1.0 CHAPTER ONE: INTRODUCTION
1.1 Background
According to (Insurance Services Office, 2014), During World War II, the U.S. military
endeavored to create an unmanned aerial vehicle. Reports indicate this military operation involved
a B-17 bomber equipped with TV cameras, parachutes, and explosives. The plan was for the
bomber pilot to take off, reach a designated altitude, and bail out, while a pilot in a second plane
used remote controls to guide the highly explosive plane to its target. This mission met with little
success with the pilot dying during the operation of the task.
While unmanned aerial vehicles were only in their infancy during World War II, the efforts of the
“greatest generation” helped lay the groundwork for today. Drones, or unmanned aircraft today
have become an integral part of the U.S. military. People around the world are buying drones
online and using them to take aerial photos or videos. (Overview, n.d.)Based on 2013 teal group
analyzed that civilian application of drones was at 12% and predicted that it will be 30% by
2030.Businesses are integrating drones into their long-term strategies and considering potential
uses.
According to (Cossio et al., 2012) in agriculture, the association of unmanned aerial vehicles
systems international (AUVSI) reports that over 100 drones are being used in china and japan to
closely monitor crops to improve management and yields. The association also predicts that drones
used for agriculture could comprise over 80% of future drone use.
Mining companies are already deploying drones worldwide with great efficiency and safety gains
to accurately measure site conditions, inspect pit walls, calculate quantities, and measure and map
in 3D. Photogrammetric techniques are used for 3D modelling however more precise laser LiDAR
sensors for UAV platforms will be developed in time(Raja, n.d.).
Monitoring from above of construction project sites provides a new input during all phases of a
project lifecycle. Aerial photography is currently used on only the largest projects but this will
change in the future as costs reduce. The ability to quickly model from above in 3D with increasing
precision will provide a check on projects compared to plans, as well as the better coordination of
materials on the job site. Monitoring activity across a large, complex construction site is
11
particularly difficult because there are so many moving parts, and because the jobs being
performed change frequently. A report published in 2009 by the National Research Council of the
National Academies found that construction lags behind other industries such as manufacturing in
terms of productivity, and blamed the situation on problems with planning, coordination, and
communication.
The Inspections, from pipelines to power lines to towers, to processing plants, the inspection of
complex infrastructure will benefit from regular aerial monitoring. The ability to sense in three
dimensions, take thermal readings, and to detect metal strain will greatly improve infrastructure
inspection (Cossio et al., 2012).
1.2 Problem Statement
The Construction Industry is growing and under ever more pressure to reduce costs, increase
quality, reduce work time and environmental impact. Inspection, monitoring and surveying on
large construction projects are very intense, expensive and time consuming activities. This is
especially so for road, railway and pipe line construction projects where surveying, inspection and
monitoring costs are high, efficient monitoring is difficult due to the longevity of the structures. In
tunnel and bridge construction workers are told to inspect in very dangerous and unhealthy
conditions. According to (Irizarry, Gheisari, & Walker, 2012), the construction industry is one of
the most dangerous industries in the world with a fata rate of 9.5 per 10,000 full time workers.
There is also an increasing demand for real time inspection, monitoring and data processing
imagery to develop more accurate and reliable 3D images. On the other hand drone technology
has developed beyond military use and various civilian applications have started to be incorporated
into the society. In the construction industry the use of unmanned aerial vehicles can make
inspection, monitoring and surveying on large construction projects faster, less costly, safer, more
reliable and accurate.
1.3 Main Objective
Is to assess the applicability of drone technology in Uganda’s construction industry.
12
1.4 Specific Objectives
1. Identify the activities drones can perform in the construction industry.
2. Assess the costs involved in using a drone to perform the activities.
3. Review the rules and regulations surrounding the use of drone technology in the
construction industry.
4. Identify the challenges facing the use of drone technology in the construction industry.
5. Assess whether drone technology can be adopted in the construction industry.
1.5 Significance of Study
 The study and research findings will help to policy makers or implementers in Uganda
to understand drone technology, their relevance in the construction industry and their
significance in addressing the issues involved in monitoring, inspection and surveying.
 The study will create awareness to the public about the existence of drone technology
and the advantages of acquiring one.
 The researcher seeks to help students in the related field to benefit from the findings
and also give room for more research in same field of drone technology
1.6 Scope of study
1.6.1 Academic Scope
This research is to concentrates on the drone technology, what activities they can do in construction
and also embodies the rules and regulations surrounding the use of drones and economic impact
in terms of costs involved in their use.
1.6.2 Geographical Scope
The geographical scope is to base in Uganda. The study will be looking at the large construction
projects that are taking place all over the country that may necessitate the use of drone technology.
Particular emphasis will be placed national roads, the Uganda section of the Uganda-Kenya
standard gauge railway
1.7 Justification of the Study
There is hardly any literature discussing the impact of drone technology on the construction
industry in Uganda. There is also a misconception about drone technology as only military based.
13
Unlike previous worldwide researchers, this particular research will focus on what activities drones
can do in the construction industry, their economic and social ramifications and whether they can
be integrated into the country’s construction industry.
14
2.0 CHAPTER TWO: LITERATURE REVIEW
Introduction
This chapter provides an insight into the history unmanned aerial systems, their evolution,
definition, types and why they are needed.
2.1 Definition of Drones
(Industry, 2014), A drone is an aerial vehicle which does not have an on board pilot. They are
officially known as UAV’s (Unmanned Aerial Vehicles). They have been brought into public
attention due to their uses in recent military operations, though their civilian use has been going
on since the 90’s, mainly in agriculture.
(AIS, 2013),Defined by the U.S. Department of Defense as “an aircraft or balloon that does not
carry a human operator and is capable of flight under remote control or autonomous
programming,”
2.2 Drone Companies
From commercial drones for civil applications to military unmanned aircraft, this selection of
game changing companies reveals the potential of the very fast growing drone market. The selected
companies are based all around the world, with a focus on Europe and France(Agarwal, Mohan,
& Kumar, 2014).
2.2.1Titan
This company founded in the USA in 2012 and mainly deals with constructor clients. Titan has
developed a solar powered drone that can navigate for up to three years at a twenty kilometers
altitude. The drone is 15 meters long with a 50 meters wingspan.
Google bought Titan in April 2014, and could use its drones to enable Internet access in remote
areas, in addition to taking high-quality images for
Google maps. Facebook had allegedly entered into discussions with Titan a few months before its
acquisition by Google.
15
2.2.2Delta
This is a company that was founded in France in 2011. It mainly has constructor clients with a
head count of over 30 employees and an investment of over 3.9 million pounds. By 2013 the
company had turnover of over 696,000 pounds Delta Drone has developed two drones: one with a
fixed wing, the other with a rotary wing. The main focus is inspection, but the drones can also
operate in sectors such as agriculture or geology.
The company offers both a renting model and a service model. It has created the Ecole Française
du Drone , to train drone operators. Unlike its competitors, Delta Drone has decided to go public
very quickly, and has been listed on Alternext since June 2013.
2.2.3 DJI
This company was founded in china in 2013 with over 800 employees and turnover of $131m
The star product of DJI is the Phantom, a mass market drone launched in January 2013, and
available from $500 (without the camera). The company has grown its sales very quickly, with an
average of 20,000 units per month since its launch, and is now Parrot’s most serious challenger on
the market. DJI has released a second version of the Phantom in December 2013. The Phantom
now starts to be used for surveillance and film-shooting purposes.
2.2.4 Parrot
Founded in 1994 by Henri Seydoux, Parrot has been widely investing in the drone sector since
2010, and has become a global leader in drones with its famous A/R drone - until the arrival of
DJI on the market. The company strategy is to accelerate its sales in the market by launching new
products and enhancing its distributors network, while developing its business (which represented
15% of 2013 turnover).
2.2.5 Sense Fly
This company was founded in Switzerland in 2009 with a financing of over $4m and a turnover of
$6.3m by 2013. The main product of Sensefly is a fixed wing drone called the eBee. Its
applications range from agriculture (monitoring of crop health, with a dedicated sensor developed
by Airinov) to 3D mapping (via a software developed by Pix4D, another Parrot subsidy). More
than 500 drones were sold in 2013, at a price around €15k. Parrot took a majority share (56,6%)
in Sensefly in July 2012
16
2.2.6 Airinov
This company was founded in France in 2010 with over 10 employees and financing of $ 1.6m.
With the help of INRA, Airinov has desiged a sensor that analyzes the reflection of the sunlight
on the plants, so as to estimate the crop health. The data is then analyzed in a dedicated software.
The sensor is implemented in Sensefly’s eBee . Parrot took a minority stake in Airinov (20.9%)
in February 2014.
2.2.7 Gimball
This company was founded in Switzerland in 2014.Gimball aims to operate in inaccessible places.
The drone can navigate close to infrastructures, since it will not be damaged if hitting an obstacle
thanks to its spherical carbon fiber protection. It can be used for inspecting tunnels, power plant
boilers, wind turbine blades, etc. The drone also has a strong potential, since it is less dangerous
than usual drones.
2.2.8 Novadem
This company was founded in France in 2006 Novadem is a French company specializing in rotary
winged drones. It has developed three drones for three specific markets: military, inspection, and
photo/video. One of Novadem’s drone’s advantages is that they can be easily folded, which is key
forthe military market in particular
2.2.9 Tech Ject
This was founded in USA in 2012.Techject has gained a lot of visibility with its Dragonfly drone,
which was originally financed through a $1m grant from the US Air Force, and then with a
Indiegogo campaign that helped raise more than $1m. The drone is 15cm long and imitates the fly
of a dragonfly, with flapping wings, which allows it to be used in spying and security scenarios.
The drone is the result of four years of R&D at Georgia Tech. A similar approach has been taken
by the American company AeroVironment ($250m of turnover), with its Hummingbird drone.
2.2.10 Red Bird
This company was founded in France in 2013 Redbird is an operator. The company does not
manufacture drones, but it flies them. Among the drone constructors supplying Redbird are
DelairTech and Gatewing (fixed wing), MicroDrones (rotary wing). Missions include inspection
17
of transportation networks, mines and quarries, realization of 3D maps (photogrammetry),
surveillance, etc
2.2.11 Photo Kite
This company was founded in Switzerland in 2014. Photo kite offers a different approach to the
drone market. Considering that flying a drone is a rather complicated task, requiring usually hours
of training, photokite has developed a drone attached to a tether, hence very easy to operate: the
user orientates the drone, turns it on, and then releases it; he can move the drone with the tether,
just like he would do with a dog - or a kite. Other than photo/video usages in the B2C market,
photokite has applications in the B2B Market: photo/video journalism, inspection.
2.2.12 General Atomics
This company was founded in the USA in 1955 and now has financing of over $2.4bn. General
Atomics is an American defense contractor. Its MQ1Predator drone is one of the most famous
military drones, and has been used in many exterior operations by several armies. It is 8 meters
long with a 17 meters wing-span, and its max endurance is 40 hours. The following version, the
Predator B, has been sold to the American, French, British and Italian armies. The Predator C is
currently under testing.
2.2.13 Cymber Hawk
This company was founded in Scotland in 2008. Cyberhawk drones conduct close visual and
thermal inspections of industrial assets both on-shore and off-shore such as flares, wind turbines
and utility transmission towers. Using a drone to realize such hazardous tasks means that the
infrastructures do not have to be shut down during the inspection, which allows to realize important
savings. Cyberhawk’s clients are mainly oil and gas companies, such as Exxon Mobil, Shell, Total
and BP. Cyberhawk raised £1.25m in June 2013, so as to accelerate its growth and enter new
markets.
2.2.14 Micro Drones
This company was founded in Germany in 2005.The star drone, the md4-1000, has a flight time
of up to 88 min. and a payload of 1200g. It can be used for security, surveillance and inspection.
The German police, as well as the Swedish and Chinese police, are among its clients.
18
The company has sold more than a thousand drones, and focuses on expanding its resellers
network. Micro drones also distributes the PIX4D software (in which Parrot has invested in July
2012) to complete its off
2.3 Types of Drones
There are so many types of civilian drones on the market. Civilian drones now count for 70% of
all manufactured drones in the world(Babel, President, Risk, & Consultant, n.d.). Some of them
include the following;
2.3.1 DJI Phantom 3 and Phantom 2 Series
One of the best drones for sale right now is the Phantom 3. Here are some of the features that make
the Phantom 3 my favorite drone.
 4K Video with 12 Megapixel Photos
 Live HD Video streaming to your mobile device (can also stream to YouTube)
 Powerful Mobile App (just like the DJI Inspire)
 Faster Charging Battery Charger
 Advanced Vision Positioning for Indoor Flight
 True 20-minute flight times.
 Free In-app Flight simulator for learning to fly.
By the time the research was made the Phantom 3 was priced at $1259 the Phantom 3 for the
easiest drone to fly with the most flight time, features and great video quality, the Phantom 3 is the
only option that one would recommend to just about anyone. There are a few other drones that
have similar functionality to the Phantom 3. The Phantom 3 comes in four different models. At the
top of the food chain, DJI’s Phantom 3 Professional comes standard with follow-me, GPS
waypoints, point-of-interest, optical-flow and ultrasonic sensors (for height and position hold when
no GPS signal is available), 4K video recording, 20-minute flight times and more. The Phantom 3
Advanced will do everything that the Phantom 3 Professional can do, but at 1080p instead of 4K.
At $700, the Phantom 3 Standard is the cheapest Phantom 3 you can buy. It has a cheaper controller
design (taken from the older Phantom 2), no optical-flow or ultrasonic sensors, but it still has
follow-me, GPS waypoints and shoots 2.7k video.
19
With the Phantom 3 Standard, you’re basically getting something comparable to a 3DR solo with
a GoPro Hero 4 Silver and gimbal for less than half the cost. The last model which came out a few
weeks ago is the Phantom 3 4K. It has a lot of great features like 4K but at the same price as the
Phantom 3 advanced.
Figure 1 DJI Phantom 2 Figure 2 DJI Phantom 3
2.3.2DJI Inspire 1 & Inspire 1 PRO w/ 4K video
The DJI inspire 1 is the most professional ready-to-fly drone one can buy. It is probably one of the
most advanced quadcopters. The Inspire 1 comes standard with all of the features of the Phantom
3 Professional, but with a much bigger and higher quality design. It's almost twice as big and twice
as fast as the Phantom 3 and with its transforming design, the propellers will almost never be seen
in your videos. Additionally, the Inspire 1 comes with a 4K camera on a 360 degree panning
gimbal, which means that one can control the motion of the camera completely independently of
the Inspire 1. This makes it great for dual pilot operation, but also for getting locked in shots in
almost any wind conditions.
For Professional video use, the Inspire 1 comes in two other variants with superior Image quality
to even the most expensive aerial platforms in it’s size. If one need a high quality camera for
shooting pro quality video The Inspire 1 pro is a version of the inspire 1 that features a micro-four-
thirds 4K camera with 13 stops of dynamic range, interchangeable lenses and a sensor that’s 8
times larger than the standard Inspire 1 camera.
The inspire 1 costs about $2900 and is mainly for people who want an amazing tool for aerial
photography, videography, search and rescue, 3D mapping, or any other professional application.

2.3.3 Yuneec Q500 4K
Compared to DJI and 3D robotics, Yuneec is a relatively unknown company, however that hasn’t
stopped them from competing. The q500 4K is the newest model from Yuneec and as the name
implies, it shoots 4K video just like the Phantom 3 and Solo. It has lots of great features for the
price. For example, it comes with two batteries and a hand mount that allows you to take the
camera (and gimbal) off the quadcopter to use it as a mini handheld stabilized camera system.
$1300 is cost of Q500 4K. Because the Q500 4K isn’t super popular compared to the other models,
one will not find a lot of information and videos about it yet, nor will there be any third-party
accessories available. The most interesting feature of the Q500 4K is that it has a android device
built into the controller, so there’s no need to use your tablet or smartphone, although the quality
of the screen on the controller is definitely subpar compared to an iPad.
Figure 5 Yuneec Q500 4K Figure 6 Yuneec Q500 4K
21
2.3.4 3DR Solo
The 3D robotics Solo is extremely functional and easy to use. It has many features similar to the
Phantom 3 but instead of using a built-in camera, it uses the GoPro Hero 4. This means that you
have the ability to take the camera off and use it for whatever you want. The biggest difference
between the Solo and almost any other ready-to-fly camera drone is that it’s modular/upgradable
but still easy to use. It has a gimbal bay and an accessory bay, meaning that third-pardy companies
can easily make new gimbals along with other accessories. One can get the Solo for only $999,
however this price does not include the GoPro or 3 axis gimbal. If one wanted to get the Solo with
the 3DR gimbal and a GoPro Hero 4 Black Edition, the total cost will be around $1900.
Figure 7 3DR Solo Figure8 3DR Solo
2.3.5 Hubsan X4
The Hubsan X4 is about the same size as the Nano QX, but roughly half of the price. There’s 4
different versions of the Hubsan X4. The cheapest version is about $45 USD (including the
controller). It doesn’t have an Agility mode like the Nano QX so you can’t fly with complete
manual control, but it’s pretty fast and maneuverable (even with auto leveling). It also has 6 LED
lights which can be turned on and off from the controller. Speaking of controllers, the controller
that comes with the 3 cheaper Hubsan models is actually pretty nice. The next 2 versions of the
Hubsan X4 have cameras. They’re slightly bigger and heavier than the cheaper version of the X4,
but the flight time is about the same. The H107C is the version with a standard definition camera
and the 61170-02 is the one with a 720p camera. The only problem with the HD version is that it’s
more expensive and the flight time is slightly less.
22
The most expensive version of the Hubsan X4 is the H107D. It’s mainly for FPV, which allows
you to see everything that the drone can see in real time. The design is slightly different from any
of the other models and it has a black antenna on the bottom.

2.3.6 Blade Nano QX
The nano QX is a lot like the LaTrax Alias but smaller. Because it’s a few inches smaller than the
Alias it doesn’t have as much authority. It has two flight modes, stability and agility. In agility
mode, you have full control over the quadcopter to learn how to fly manually (it will not auto level
itself). In stability mode, it will automatically level itself when you let go of the controls.
The nano doesn’t have the auto flipping functions that the Alias does. Since the Nano QX is smaller
than the Alias, it’s only $90 instead of $150. One of the major problems about having a smaller
quadcopter like the Nano QX is that it’s harder to see when flying far away, so it’s easier to lose
orientation.

2.3.7 Parrot Bebop
The Parrot Bebop is one of the more technologically advanced drones for sale right now. It’s the
AR Drone’s smaller, smarter, faster and more expensive little brother.
Just like the AR Drone, you can control the Bebop with your iPhone or Android device. But with
the Bebop, there’s an optional Sky Controller which will allow you to have real joystick controls,
extended range, HDMI output and a few other cool things.
The Bebop has a lot of improvements over the AR Drone 2.0, but the most interesting feature is
the video system. It has a 14-megapixel camera with a 180-degree field-of-view fisheye lens. Since
the camera lens has such a wide field-of-view and a really fast processor, the Bebop is able to take
the full 14-megapixel image, fix the image distortion (eliminating the fisheye effect), stabilize the
image, then send the live video back to your phone. What all that means is that you’ll be getting a
digitally stabilized standard definition video feed straight to your phone. At the same time, It also
records digitally stabilized 1080p video to the 8GB of onboard memory.
The price for the Bebop is $499 USD and you have to use your smartphone to fly it, which means
that you won’t have precise controls unless you buy the optional $400 Sky Controller (making it
$899 USD total).

2.3.8 Tbs Gemini
The TBS GEMINI is a tiny little hex copter designed specifically for FPV (first person view)
racing. It’s actually one of the only FPV racing drones for sale that comes ready to fly.
24
The first thing that one would notice when watching videos of the GEMINI is the fact that it hovers
with the nose tilted up. This is because all of the motors are tilted forward by about 10 degrees.
Doing this will actually improve the performance of the drone by decreasing drag and increasing
speed in forward flight. Another cool feature of the GEMINI is the modular design. If one was to
look on the inside of this little hexacopter, you would notice it’s not like a typical hobby grade
drone. Like the QAV400, the GEMINI isn’t for everyone though. It’s mostly intended for people
who want to get into the hobby side of drones and just want something really small and fast for
FPV.As far as price goes, it’s about $600. Availability for the GEMINI is pretty good, so one
shouldn’t have a super hard time getting it.
Figure 15 TBS Gemini Figure 16 TBS Gemini
2.3.9 3d Robotics Iris +
Out of all the drones for sale, (other than the AR Drone) the IRIS has the biggest list of features.
In a nutshell, the IRIS is for people who have never owned a drone before, but want something
that they can tinker with and modify.
It has a lot of auto-pilot features such as auto takeoff and landing, GPS waypoint flight (with a
computer or android device), live data telemetry and more. You can also order the IRIS with a
brushless gimbal for the GoPro (made by a company called Tarot) for shooting aerial video.
The IRIS is an interesting quadcopter, especially for people who want to learn about flight
controllers and how auto-pilot systems work. It costs about $750.The iris is also not that user
friendly.
25
Figure 17 3D Robotics Iris + Figure 18 3D Robotics Iris +
2.3.10 3d Robotics X8+
The 3D Robotics X8+ is like the tank of ready-to-fly drones for sale. it has 8 motors that turn large
11 inch propellers. With all that power, it's able to lift over 800g (about 2 pounds) of payload,
making it a great option for lifting large cameras and LIDAR systems.
Basically, the X8 is like the bigger brother of the IRIS. It has the same flight controller, but the
electronics are just bigger and better. One good thing about having 8 motors in this configuration,
is that you get extra redundancy. For example, one motor could completely shut off and the drone
would still hover in the air without any issue.
Another feature that both the X8+ and IRIS+ have is the popular "follow me" feature that everyone
talks about. In this mode, the drone will try to follow you around by getting GPS position
information from your smartphone.

2.3.11 Quanum Nova
If you’re on a budget and want a lot of features for your money, the Quanum Nova is probably the
best option. It has a similar shell design to the DJI Phantom 2, but it’s running the same software
as the 3D Robotics IRIS, which means that it has almost all of the features of the IRIS (with the
exception of data telemetry) at a fraction of the cost.
The Quanum Nova is only $300 which is very low for what it can do. One has to buy the battery
and charger separately, but even when adding that to the full cost it would only be about $400 for
everything ($350 less than the IRIS). Just like the IRIS, the Nova also has an optional brushless
gimbal for the GoPro that costs $100 extra. The main thing to take into consideration with the
Quanum Nova is that it’s a very cheap quadcopter.
Figure 21 Quannum Nova Figure 22 Quannum Nova
2.3.12 Latrax Alias
If one wanted to learn how to fly a quadcopter manually, the LaTrax Alias is a great way to start.
The reason why it’s a good quadcopter to learn with is because it has a full manual flight mode
and it’s extremely durable. This means that you can learn how to fly without worrying too much
about crashing.
Since it’s about 7 inches wide and has big propellers it also has great authority, so doing bank
turns, pirouette maneuvers and more would be no problem. It’s also big enough to carry a small
camera like the 808 keychain camera. People install video transmitters and do FPV. The Alias
costs around $150.

2.3.13Parrot AR Drone 2.0
When the AR Drone 2.0 first came out, it was one of the coolest drones for sale on the market. It
has a 1GHz 32 bit processor, 1GB of ram, gyros, accelerometers, magnetometers, a pressure
sensor, an ultrasonic sensor, 2 cameras and more. Even though it’s over 2 years old, the AR Drone
is still one of the most advanced quadcopters available in its price range which is $299.
The biggest feature of the AR Drone is that it can be controlled from your iPhone. One can also
see a live video feed from the phone screen and record video. It’s even running Linux and there’s
an AR Drone open API platform, so you can program it to do whatever you want.The AR drone
can only be controlled with your phone, meaning that you can’t use a normal RC controller with
real control sticks. That also means that there’s no way to fly manually.

2.3.14 QAV400
The QAV400 is a quadcopter designed for sport flying and FPV (first person view). It’s actually
just a frame that’s sold so people can add their own electronics to it, but you can get a ready-to-fly
version with all of the electronics installed if you’re willing to pay extra.
The feeling you get when flying FPV with this quadcopter is absolutely amazing. That being said,
I wouldn’t recommend buying anything like this unless you already have experience with RC
planes or helicopters. This is truly a hobbyist type of multirotor and all of the parts and components
are high quality, customizable and made by completely different companies. So getting it set up
and fixing it when you crash would be a lot harder than most of the other ready-to-fly options out
there. The price for this quadcopter is $970 which is normal for ready-to-fly multirotors in this
category.
Figure 27 QAV 400
2.3.15 Proto X
The Proto X is one of the smallest drones for sale on the planet. It has 3 gyros, 3 accelerometers,
4 motor speed controllers and a radio receiver all shoved into a tiny PCB board about the size of a
quarter.
The price for this little drone is only about $38. It’s one of the cheapest quadcopters you can buy
(but cheap isn’t necessarily a good thing). It’s very fast for how small it is, but at the same time
since the rotors are so small and close together, people have found that it’s a bit hard to do bank
turns with it. Since the Proto X is so cheap, there is a chance that you could buy a defective one,
but you can always just send it back.

2.4 Classification of Drones
According (Juty & Morris, 2015),The definition of UAVs encompasses fixed and rotary wings
UAVs, lighter-than-air UAVs, lethal aerial vehicles, decoys and targets, alternatively piloted
aircrafts and uninhabited combat aerial vehicles.
Unmanned aerial vehicles can be:
 Remotely piloted aircraft (RPA) controlled from the ground.
 Autonomously controlled by on-board computers.
 Pre-programmed to fly specified routes.
According to (PeterWijninga, Sijbren de Jong, 2015), drones can be classified under three major
categories,
2.4.1 Class III
These are drones that have a weight of over 600kg. The class iii drones come in three different
types, UCAV, HALE and the MALE.
The UCAV is basically a military, combat and tactical strike drone. It has an average elevation of
20km.the drone is usually used to an unlimited line of sight. They use an acquisition, target and
designation sensor suite. Examples of these drones include Pegasus, Phantom Ray, nEUROn, Skat,
AURA. Currently they are not being used for any civilian applications.
The HALE is used for strategic and national observation during military surveys. It also has an
average elevation of 20km. the drone is also used for an unlimited line of sight. They use SAR/MTI
sensor suite. These drones are also used real time imagery of large geographical areas. Example
of this type includes the global hawk and the Euro hawk.
The MALE, this is also used for strategic and national observation during military surveys. It is
very similar to the HALE. The only difference is its appearance and that it uses a ground search
radar and laser range finder as the sensor suites.
2.4.2 Class II
These are drones that basically are in the weight of between 150-600kg.In the military they are
used for tactical observation and strike operations. They can fly up to 3km in the air and have a
30
200km line of sight. Some civilian applications include real time high precision imagery of
geographical areas. Examples include sperwer and aerostar.
2.4.3 Class I
These are drones that weigh below 150kg. they come in three versions; small, mini and micro
drones. In the military they are used for tactical individual observations. They can fly up to 1km
in the air. Examples of these include black hornet, scan eagle, raven and aladin.
2.5 Evolution of Drones
According to (AIS, 2013)Unmanned systems have been in use by American armed forces since
1917, when the Kettering Aerial Torpedo flew using preset pneumatic and electrical controls.
Radio control technology enabled the use of pilotless flight in both world wars on a limited basis,
and improvements in altimeter, gyrocompass and guidance technology led to increasing
deployments during the Vietnam era. From 1964 to 1975, the U.S. Air Force flew 3,435
reconnaissance drone missions over North Vietnam and its surrounding areas, and lost 554 UAVs
during the conflict.9
With the advent of GPS technology, stealth-based three-dimensional thrust vectoring flight control
[jet steering], and advanced avionics, UAS entered the modern age in the late 1980s, when they
were effectively deployed for reconnaissance by the Israeli Air Force, and later by the United
States in the Balkans. In 1999, the United States flew 100,000 flight hours with unmanned systems.
Today, the United States flies more than 1 million unmanned flight hours annually, and the
Department of Defense operates more than 7,000 UAS. The growth of unmanned systems for
military and civil use is projected to continue through the next decade. It is estimated that UAS
spending will almost double over the next decade, from $6.6 billion to $11.4 billion on an annual
basis.
2.6 Factor to Consider Before Using a Drone
There are a range of factors to be considered when specifying an adequate unmanned aerial system
for a certain application. Some general considerations whilst others are dependent and relative to
the final purpose of a particular task the UAV must perform. The most relevant factors to account
for when choosing a UAV system are listed and briefly described below.
31
2.6.1 Flying Time, Distance, and Area Coverage
The extent of the area to survey is crucial for selection of an adequate UAV, capable to cover the
area in a reasonable time and with affordable power consumption. Among N-rotor platforms, DJI
claims that the Phantom Quadcopter can fly at horizontal speeds of 10 meters per second (36 km
per hour). However, given the battery life and energy required to travel vertically, it is not possible
to fly more than 2-4 kilometres from the ground location origin. The maximum vertical speed is 6
meters per second, meaning it can rise to 30 m in as little as 5 seconds!
2.6.2 Flying Height and Ground Control
Realizable flying heights for UAVs depend very much upon the type and size of the platform, the
‘fuel’, and the means of control. In the case of large drone-based systems the flying height can be
over 9000 m. Some small platforms can climb to 600-700 m although most are restricted by the
control unit typically to heights below 400 m, when the control signal is lost. Generally small
platforms do not need to fly at such high altitude: for small area surveys where high resolution
imagery is required, the flying height may be only around 5-10 metres. For example, in order to
achieve 3.3 cm Ground Sampling Distance (GSD) imagery, a UAV may only be required to fly at
100 m high. As the flying height increases, the area coverage increase, and the image resolution
decreases, depending on the camera resolution.
2.6.3 UAV Altitude Control
The flying height of a UAV depends on the characteristics of the platform and mission, but is
determined in particular by the propellers and the payload. Maximum flying time decreases when
flying height increases. Because the rotors spin faster to get higher altitude, the motors and the
entire system become hotter during the high flights. There is a noticeable decrease in performance
when going higher than 3000 m above sea level. However, this is unlikely to be a problem in the
UK where 400 feet is the maximum permitted flying height.
2.6.4 Manual and Automated Launch / Landing
Many small UAVs (e.g. N-copters) can take-off and land on the ground with or without the aid of
a landing pad. Some can also be hand launched and landed, making them very flexible and easy to
use. Larger and more sophisticated UAVs (N-rotor or fixed wing) require some form of launching
device to facilitate the take-off of the platform. These pieces of kit are additional equipment that
makes the logistics of the mission less easy and flexible. Safe retrieval is important and whilst
32
many platforms can be easily landed in areas of grass or bushes, this is not always possible. In
order to prevent damage to the sensors and aircraft, recovery options including parachute and
homing systems have been developed for recovery.
2.6.5 System Failure and Retrieval
System failure is not impossible or unlikely, and whilst most UAV platforms are now ReadyTo-
Fly (RTF) systems, problems can arise including rotor failure, fly-aways, and motor malfunction
amongst other things. Depending on the severity of the problem, UAV platforms could be
destroyed or damaged beyond repair together with the on-board sensors and electronics. However,
most UAV kit is built robust, and both easy and cheap to repair. Operators should have ready to
use spares (e.g. rotors, nuts, bolts) and ensure rigorously conducted thorough checks of the system
and platform prior and in between each flight.
2.6.6 Flying Conditions
Most UAVs are restricted by the environmental flying conditions they can operate in. As most
platforms are not waterproof, this means that for the most part these platforms and their sensors
cannot be flown in anything other than dry conditions, especially for most electric powered UAVs.
If a UAV gets caught in the rain it is generally best to land as soon as possible.
2.7.7 Mission Planning
Mission planning software (http://ardupilot.com/downloads/?did=82) is now widely available
providing the basis for small UAV platforms to fly fully autonomously. Increasingly these are
designed to be plug and play and can be determined using waypoints ‘on the fly’ or via pre-
planning for an aerial sortie. Many e.g. Mission Planner and Droid Planner (see section 3.3.2 in
this report) arewidely available for use on tablets and smartphones and can be used to plan
repetitive and large area coverage flights for N-copters and fixed wing UAVs.
2.6.8 Operation and Control
In the past, most radio control model aircraft required considerable skills for launching, flying and
landing and was regarded as a specialist activity. Today, part of the attraction and rapidly growing
use of the small UAV platforms has been driven by developments in the technology allowing
virtually anyone to fly – with a shallow learning curve –small quadcopters, and more recently the
autonomous fixed wing aircraft increasingly used for aerial survey work. These days many popular
33
UAVs come ready to fly, the platform can fly in an autonomous mode in which the aircraft is
guided via GPS to pre-programmed waypoints. RTF aircraft can easily be flown horizontally and
vertically along a flight line using a monitor or goggles which display the view over which the
UAV is flying, and include altimetry, battery power and other useful parameters. Simple radio-
controlled hand-held controls, operating in the 36 MHz band or the 2.4 GHz bands, with Mode 1
and mode 2 controls – left and right joysticks – allow the UAV to be controlled easily.
2.6.9 Digital Image Processing Software
The photography acquired by UAVs can be visually interpreted with aerial photo-interpretation
techniques. Digital Image Processing (DIP) software, much of it now low-cost, can also be used
to geo-correct and mosaic the photographic prints or images together as the basis for onscreen
interpretation and the mapping of thematic information for subsequent input to a GIS. The lower
cost of PCs and accompanying hardware (e.g. storage media, scanners, printers and software)
provides opportunities to capture, store, process and map the data in-house on a regular basis.
Digital image processing (e.g. geometric and radiometric corrections) can be performed with
standard or specialized DIP software. Furthermore, there is now a small range of UAV dedicated
software packages available specifically aimed at UAV image acquisition and correction, which
have similar functionality and better price. A few examples of UAV dedicated software are listed
below: Pix4D, Mosaic Mill, AirPhotoSE, Agisoft Photoscan Pro.

3.0 RESEARCH METHODOLOGY
3.1 Introduction
This chapter consists of methods, procedures and techniques were used while carrying out the
study. It includes the research design, targeted population and sampling techniques used, the
research methodology, how the field study was carried out, how data was collected.
3.2 Research Design
Both quantitative and qualitative methods of data collection was used to measure the answers to
questions of better relationships and variables that can be obtained mathematically for explaining
purposes, predicting and controlling phenomena whereas qualitative methods were used to answer
questions about the complex nature of phenomena with the purpose of describing and
understanding the phenomena from the respondent’s point of view
3.3Study Population
The study population was selective. It comprised of country’s construction companies and
consultants with particular emphasis given to those have engaged themselves with drone
technology.
3.4 Research Tools
This research involved various techniques which included: Interview guides, these were used for
interviewing and liaising with different drone operators and service providers to establish the costs
involved in the use drone technology. These interview guides were used with various construction
companies and consultants to acquire information about drone technology awareness among the
construction professions and the reasons why they think drones have not been used by construction
companies. Interview guides were also used to identify the rules and regulations surrounding the
use of drone technology in Uganda.
3.5 Sample Design (sampling techniques)
This research adopted a non-probability sampling technique. Purposive and convenience sampling
were used to generate a respondent list. This is because samples consisted of individuals
considered to have knowledge and information drone technology and those that were easy to reach
and acquire information from.
35
3.6 Sample Size
Formula for determining sample size (Morgan ,1970)
3.7 Research Procedure
Interview Guides
The design of interview guides took into consideration the objectives of the study as stated in
chapter 1.3 and 1.4 with the aim to answer the research questions. Great effort and analysis went
into designing the guides. Meetings with university supervisor were conducted to identify the right
questions required and to present them in a clear and an unambiguous format. Special care was
also taken into phrasing the questions in a language that is easily understood by respondents.
Content of Interview Guides
Interview guide 1 as shown in Appendix had nine questions which addressed the rules and
regulations surrounding the use of drone technology. This guide was particularly directed to the
civil aviation authority as it’s the organization with the mandate to regulate any flying machine
over Ugandan air space. The questions targeted their role as regards to drone technology and
whether they had any regulations that they use to control drone activity in the country. The
interview also looked at whether there is need for one to register his/ her drone before using it. The
interview also contained questions pertaining the right procedure one needs to go through before
using his/ her drone for a particular activity.
Interview guide 2 as shown in the Appendix had 14 questions which addressed the objectives 1
and 2 of the study. The interview was directed mainly to companies and construction professional
that have used drone technology before. The questions presented to the respondents were meant to
capture their experience with drones, the activities they used them for, the reasons why they opted
to use drone technology and at what cost.
Interview guide 3 as shown in the appendix had 6 questions which addressed the main objective
of the study. The interview was directed to construction companies, consultancies that have not
used drone technology before. The questions targeted their awareness of drone technology, reasons
why they have not incorporated drone technology in their works and if they believe drone
technology can improve their monitoring, inspection and surveying techniques.
36
3.8 Data Collection
In the context of this research, interviews guides were adopted to investigate existing rules and
regulations surrounding the use of drone technology, the activities drone are doing in the
construction industry and the economic impact drone technology introduces to the construction
process. The interview was considered a suitable process of data collection that is capable to
provide rich information. This research used unstructured interviews to stimulate discussions and
breakdown any barriers between the interviewer and interviewees.
Interview guide 1 was used to interview the air rules and regulation manager at the civil aviation
authority. All questions in the guide pertaining the legislation of drone technology were answered
clearly.
42 interviews were carried out in the investigation of activities drones can perform and economic
impact drone technology introduces in the construction industry. 10 companies that have ever used
drone technology were interviewed by the researcher. 26 companies that had no incorporated drone
technology in their works were also interviewed by the researcher. The interviews were conducted
with various construction professionals and managers within the companies. The respondents were
very cooperative and willing to give information although information pertaining the costs and
maintenance of the drones, the respondents readily willing to give the information. The interviews
were then grouped according to the professions of the various respondents.
Telephone call and online chats were carried out with 6 drone manufacturing companies. These
companies were mainly based in the Europe and United states of America. The response to this
method was good as all information pertaining drone specification was acquired with additional
brochures also provided to the researcher for further information.
The raw data was edited for missing data, double entry answers and other ambiguities.
37
3.9 Challenges Faced During Data Collection
 The time factor was of one of the biggest challenges. The researcher found most his
desired respondents having busy schedules. This made it a little difficult for the
researcher to get detailed information about drone technology.
 The financial aspect may also be a limiting factor. Money needed to access the drone
service providers and the drone equipment may be financially straining.
 Most of the respondents were not willing to give information pertaining the cost
involved in the use of drone technology.
 The researcher found it difficult to get enough information about the use of drone
technology since few construction companies and consultants within the country have
used drones in their construction process.
3.10 Data Quality Control.
Drawing upon the strengths of the different methods employed in collection of data, the validity
and reliability of the research is ensured since the questioners were brief and with clear questions,
interviews were with willing parties and observations discreet to improve the quality or validity of
the data.
38
4.0 RESEARCH FINDINGS AND DATA ANALYSIS
4.1 The Activities Drone Technology Can Perform in the Construction Industry of Uganda
Applications are often focused on the military areas, surveillance, inspection of transmission lines
and power distribution; low cost filming and panoramic picturing for the movie industry, sport
events, crop and herd monitoring, among others(Gomez & Green, 2014). In construction various
application of drones are being utilized as the following would show.
4.1.1 Unmanned Aerial Vehicles Used for Monitoring Site Safety
UAVs will be able to provide real-time visual information to monitor construction site safety. As
noted by (Gheisari, Irizarry and Walker 2012), in a constantly changing construction site the safety
manager’s job of direct observation site work and interaction with workers continuously and in
real-time are an excellent application for UAVs. UAVs have the ability to reach difficult positions
on a construction site and provide live video streaming for safety managers. Hence it is possible
for safety managers to interact with site workers if the situation arises. Similarly, Irizarry, Gheisari
and Walker (2012) also discussed some of the benefits of using drones for the construction jobsite
safety management.

4.1.2 Drones Used for Traffic Surveillance
In (Coifman et al.2004) he conducted four field experiments for freeway conducted, intersection
movements, network paths, and parking lot monitoring. The UAV, equipped with an on-board
camera, was flying low (i.e. at an altitude of 500 ft) and an air speed of 30 mph while transmitting
39
the video images and providing aerial surveillance. He concluded that the UAS could eventually
be airborne most of the time since the operator would be on duty for any emergency calls.

4.1.3 UAV’s Used for Monitoring Structures
(Irizarry & Johnson, 2014), Inspecting and monitoring linear infrastructures such as roads,
pipelines, aqueducts, rivers, and canals are very important in ensuring the reliability and life
expectancy of these structures. A UAV can stay or fly on top of the structures and transmit a
precise image or video stream for inspecting and monitoring purposes. A study, sponsored by the
Office of Naval Research's (ONR) Autonomous Intelligent Network and Systems (AINS)
program, aimed to develop a control technology that can be used to produce infrastructure
monitoring or inspection video using an autonomous UAV. While most UAVs are commanded to
fly along a path defined by a sequence of GPS points (called waypoints), this study tried to improve
the performance by putting an imaging sensor to detect the linear structure. Therefore, the UAV
with a camera can navigate based on visual information rather than GPS information.
4.1.4 Aerial Assessment of Road Surface Condition
The assessment of road surface distress is an essential part of a road management system for
developing repair and maintenance strategies to ensure a good and an effective road
network(Irizarry & Johnson, 2014). Over the last decades, significant progress has been made and
new approaches have been proposed for efficient collection of pavement condition data. An
innovative UAV-based digital imaging system for aerial assessment of surface condition data over
rural roads has also been developed. The system for unpaved road image acquisition consists of a
40
UAV helicopter equipped with a digital camera, a GPS receiver, a ground control station, an
Inertial Navigation System (INS), and a geomagnetic sensor.
The UAV features an electric engine with a payload of 15 lbs (6.8 kg) and is capable of flying
around 25 minutes with a fully charged battery. It can reach 650 ft (approx. 200 m) above the
ground and travel at a maximum speed of 30 ft (approx. 10 m) per second.

4.1.5 Bridge Inspection
Field engineers and technicians working in infrastructure construction or inspection projects need
to conduct regularly scheduled routine inspections of highway bridges in order to determine the
physical and functional condition of a bridge and to identify changes compared to previous
inspections(Irizarry & Johnson, 2014). Furthermore, these inspections are conducted to ensure that
a bridge continues to satisfy all applicable serviceability requirements. In LCPC-Paris have started
a project pertaining to civil applications of a UAV for bridge inspection and traffic surveillance.
A UAV capable of quasi-stationary flights was used to inspect the bridge and detect the location
of defects and cracks. The UAV was equipped with a camera, an image transmitter, and a vision
system that included INS and GPS. It followed a predefined path and was controlled by visual
surveying (vision-based robot control). The size and location of defects and cracks were detected
through image treatment. In order to keep the object in the camera's view field, the research team
presented a control strategy for the autonomous flight with orientation limits.

4.1.6 Drones Used for Real Estate, Urban and Regional Development
The Urban regional authority of Australia is currently exploring using aerial images captured by
drones to create 3D digital models of our built heritage and city areas. This is done using a
technique called photogrammetry, which is the science of making measurements from
photographs. Urban regional authority of Australia and local drone start-up Avetics have worked
on a trial to create a 3D digital model of the Baba House at Neil Road. Creating fine-grained 3D
digital models of our built heritage potentially offers a new dimension to document our conserved
buildings in more intricate and accurate detail. Planners can use these digital models to plan and
carry out research, guide restoration, as well as monitor and manage the state of our built heritage
in a more effective way. At the same time, it enables our conservation planners to easily ‘see’
rooftops and other aspects of conserved buildings, such as architectural motifs, without having to
physically scale the buildings. Sharing these 3D digital models with the public also enables them
to have a deeper appreciation of our built heritage.

4.1.7 Inspection of Mining Pits, Monitoring Oil and Gas Pipelines
Oil and gas transmission pipelines comprise a network of more than three million km globally
(CIA, 2013) that is in continuous expansion (Smith, 2013). Pipeline networks are made up of legs
of different lengths, up to thousands of kilometers, and can have above- or below-ground
configurations. The safety and security of all pipelines, regardless of their size, placement, or
location, is of paramount importance to stakeholders and to the public. Proper maintenance of
pipeline networks is also important for environmental protection.
Equipment failure such as breakage or leaks can occur for many reasons, including overage of
structures and material failure, natural ground movement, accidental hot-tap, and third-party
interference. (Gomez & Green, 2014) Large amounts of oil and gas can be lost following a pipe
failure, and more importantly, hydrocarbon leaks can damage the environment through
contamination and pollution, seriously affecting ecological health and human security. Developing
and implementing monitoring systems that can continuously assess the state and condition of oil
and gas pipelines is essential.
43
Traditionally, monitoring pipeline networks has often been restricted to visual inspections or
volume and mass balance measurements. Currently, most of the monitoring is still performed using
conventional methods, mainly through periodic inspections by foot patrols and aerial surveillance
using light aircraft or helicopters. Although ensuring a high level of security, the cost of monitoring
methods where there is intensive human involvement in the measurements is also very high.
Furthermore, the main disadvantage of the methods used for monitoring and inspection is the
potential for late detection of failures, when the output (oil or gas) has been reduced, or the
environment has already been affected and damaged.
Some alternative approaches to monitoring pipelines that do not over rely on human intervention,
is the use of UAVs. These can over large and remote areas in a very short and effective period.
They are periodically sent out to inspect the oil and gas pipelines in order to detect any cracks,
breakages and leakages.

4.1.8 Drones Used in Marine And Under Water Inspections
As a modern tele craft, the technology on UAV (unmanned aerial vehicle) has become maturing
and widely used in the field of military affairs and civil purpose. Due to the good flexibility, high
efficiency, low cost and damage, low risk, and excellent monitoring ability and widespread
coverage, the UAV is capable of the waterborne supervision.
44
Nowadays, the Tianjin Maritime Safety Administration, Guangdong Maritime Safety
Administration and Changjiang Maritime Safety Administration have taken a trail and commerce
project on the UAV used for the maritime supervision and monitoring of aerial cruise.
At the same time, the UAV has been put into monitoring the oil leakage at sea. A series of instances
shows that the maritime system, fitted with UAVs and some monitoring systems,

4.1.9 Aerial Surveying (UAV photogrammetry)
The new terminology UAV photogrammetry describes a photogrammetric measurement platform,
which operates remotely controlled, semi autonomously, or autonomously, without a pilot sitting
in the vehicle. The platform is equipped with a photogrammetric measurement system, including,
but not limited to a small or medium size still-video or video camera, thermal or infrared camera
systems, airborne LiDAR system, or a combination thereof. Current standard UAVs allow the
registration and tracking of the position and orientation of the implemented sensors in a local or
global coordinate system. Hence, UAV photogrammetry can be understood as a new
photogrammetric measurement tool.
UAV photogrammetry opens various new applications in the close range domain, combining aerial
and terrestrial photogrammetry, but also introduces new (near-) real time application and low-cost
alternatives to the classical manned aerial photogrammetry.
45
Existing UAVs can be used in large-scale and small-scale applications. The system price may vary
within some orders of magnitude, depending on the complexity of the system. With costs between
€1000 up to several millions of Euro, the system can be similar or even higher priced compared to
a standard manned aircraft system.

From the research who carried out there were 36 respondents interviewed about their knowledge
of drone technology. These were mainly from the professional fields electrical engineering, civil
engineering, quantity surveying, architecture and project management. 80% of the respondents
were electrical engineers. This is due to the fact that the other professionals felt they could not give
detail in sight in the use of drone technology. The other reason was most the construction
companies interviewed would direct you to the Mechanical and Electrical department that was
mainly composed of electrical engineers. This is illustrated from the graph below.
46
The graph above clearly shows electrical engineering having more knowledge about drone
technology. This is due to the fact electrical engineers interact with similar kinds of technologies
during their studies and working environment.
From the research it was determined that most construction professionals don’t know about drone
technology. This is due to the fact that it’s a new kind of technology that is not yet well sought out
and integrated in their fields of work.

The graph above shows the number of construction professionals that have used drone technology
before. From the research it was discovered that most construction professionals have not used
drone technology in their works. This clearly shows that drone technology has not yet been
harnessed or properly tested out in the construction industry.
.
The graph above shows types of drones Most common drone used is the DJI phantom 3 because
its more reliable than the other types. This is because DJI phantom 3 has a longer lasting battery,
is more resilient to windy conditions. The DJI phantom 3 is more readily available and has easier
to learn navigation and control system as compared to the others.

According to the research carried out the average number of drones used for a particular activity
is 2 drones. This is because most of the work load the companies had did not require the use of
more than 3 drones.
The figure above illustrates that 60% of the companies that have ever used drones in their activities
preferred hiring them rather than fully purchasing and owning the drones. This is because it’s
difficult to own one as few companies sell them first of all.
Secondly the costs of maintenance, repairs and having a few time drone operators are transferred
to the hiring company. The burden of looking for extra work is also placed onto the hiring
company. Most of the companies interviewed had were using drone technology in a testing a phase
and therefore did not want to commit a lot of funds towards purchasing the drones

From the research carried out it was determined that drone technology had been carried out mostly
on road design and construction projects with a few drone work carried out on buildings and
pipeline works. This is because road construction projects are more common in Uganda and tend

to cover a longer distance. This makes supervision very tiresome breeding the ideal conditions for
the use of drones.
From the research carried out it was found that 60% of companies have used drone technology
before, have used drones in average of 2 construction projects underlining the fact the drone is a
new technology that has not been fully engraved in the construction industry.
From the research carried out it was determined drone technology is mainly used for aerial
photogrammetry. This is because drone technology has made this activity far much cheaper, faster
and produced more resolute and clear aerial images as compared to the traditional use of a manned
aircrafts. Traffic surveillance and marine inspections are activities not often carried out in Uganda
that is why no drones have been used in their execution. Using drones for inspection of buildings
is still low in Uganda because the types of high resolution cameras that are used for building
inspection are still very expensive. There is also high difficulty in maneuvering a drone around a
building structure for inspection(Irizarry et al., 2012).
80% companies interviewed did not employ any drone specialist. This is because most of the
companies do not use drone technology a lot therefore did not find economically viable employ
them.

70% companies interviewed use roughly 1 to 3 drone operators when utilizing the drone. One
person flies the drone, the other directs the operator and looks out for any obstacles to avoid any
collisions.
The tables show the average cost of purchasing a drone, the average operational costs per day and
the annual maintenance costs. This information was obtained from various drone manufacturing
and distribution companies that included aeryon labs, sensefly, and DJI

DJI phantom 3 has the highest purchasing price as seen from the table above. This is because of
its higher specification capabilities and very high demand on the market.

4.3 Rules and regulations surrounding drone technology all over the world
Regulations
With the rapid development of UAV applications worldwide, coupled with a fair number of
ongoing incidents and accidents concerning UAVs and other airborne platforms usually
highlighted by the media, there is a growing call worldwide for tightening-up the current rules and
regulations concerning who, what, where and when UAV platforms can actually be flown. Already
in many countries (e.g. the UK, USA, Australia and Canada) there are moves to regulate UAV
flights, and to necessitate education and training of operators and pilots, including best practice,
guidelines, and operator insurance amongst many other things. Whilst the UK and USA have been
relatively slow in addressing this rapid growth in platform and user-base, Canada is frequently
cited as moving in the right direction concerning the rapid proliferation of a wide range of UAV
technology, from the hobbyist to the commercial service provider(Juty & Morris, 2015).
In 2007, a group of national authorities under the leadership of The Netherlands joined in an effort
to develop harmonized operational and technical regulations for “light” (i.e. less than 150 kg)
UAS. JARUS (Joint Authorities for Rulemaking on Unmanned Systems) is open to participation
from all civil aviation authorities and current participants are from European and non-European
countries. JARUS is organized in seven working groups focusing on diverse guidance and
regulatory aspects (e.g. detect and avoid technology, command control and communication). The
primary output will be recommended operational requirements and certification specifications. For
example, the group dealing with technical requirements of platforms is focusing on establishing
certification specifications for various types of aircraft, starting with light unmanned rotorcrafts.
Expansion of UAVs and applications will have an impact on the airspace, but other industry areas
will also be affected and need regulations and adaptation. UAV communication with the ground
control system (GCS) requires radio frequencies with sufficient band width. The International
Telecommunication Union (ITU) has not yet allocated such bandwidth to UAVs, hence they may
have to use different radio frequencies in every country (Everaerts, 2008), something to be
considered by international operators and manufacturers.
54
4.4 EU Regulations
The capacity and responsibility to regulate UAVs rely on different bodies internationally. In
Europe the European Aviation Safety Agency (EASA) regulates all aspects in relation to UAV
that have a Maximum Take Off Mass (MTOM) of over 150 kg, while national Civil Aviation
Authorities (CAA) deal with light systems less than 150 kg (including fuel) which should fly at
altitudes below 150 m.
Legal operations with UAVs in Europe currently require:
 The RPAS (RPA and remote pilot station) to be certificated or approved by the National
Aviation Authority (NAA) of the country where the operation takes place, or certificated
or approved by a Regional Authority (RA) with delegated authority. This certification
should cover all system constituents necessary for command and control (e.g. transceivers)
installed on board the RPA/UAV or on the ground, and under direct management of the
Operator.
 The Command & Control link to be provided by a Communications Service Provider
(COM SP) has to be certificated or approved by the NAA or a RA of the country where the
operation takes place;
 The Remote Pilot (RP) has to be licensed by the NAA of the country where the operation
takes place.
 The Operator has to be certificated, approved, or authorized by the NAA of the country
where the operation takes place, and is required to possess the obligatory third party
liability insurance (which may vary in function of the type of operation). For a specific
aerial operation, approved operators have to apply for a flight authorization using a specific
RPAS in a defined area, possibly on specific day(s). The duration of the validity of the
flight authorizations varies from one day to two years in different EU countries.
The International Civil Aviation Organization (ICAO) aims to provide fundamental international
regulatory framework through standards and recommended practices with supporting Procedures
for Air Navigation Services (PANS) and guidance material, to underpin routine operation of UAS
throughout the world in a safe, harmonized in a seamless manner comparable to that of manned
operations. According to ICAO, only Remotely Piloted Aircraft (RPA) will be able to integrate
into the international civil aviation system in the foreseeable future.
55
RPA that utilize visual line of sight (VLOS) as the basis for navigation would not require an on-
board means for determining position or the ability to fly an instrument approach. Operations of
these aircraft are usually conducted under visual meteorological conditions (VMC) to ensure the
remote pilot can maintain continuous and direct visual observation of the RPA and its surrounding
environment. In cases where small RPA have a requirement to fly beyond VLOS, they will need
a means to meet navigation capabilities for the airspace within which they are operating. This
could involve an alternative means of achieving the navigation performance. RPA that traverse
several airspace volumes may operate for the most part under Instrument Flight Rules) (IFR). Such
RPA will have to meet the communications, navigation, and surveillance requirements and have
an appropriate aircraft operational certification associated with the airspace.
4.5 UK Regulations
The Civil Aviation Authority (CAA) in the UK has regulated UAS flights in two documents which
are eventually updated to incorporate relevant changes: CAP393 Air Navigation: The Order and
the Regulations (CAA, 2014), and CAP 722 Unmanned Aircraft System Operations in UK
Airspace (CAA, 2012). Small Unmanned Aircraft (lightweight UAVs of less than 20kg) are
exempted from the majority of the UK Air Navigation Order (CAP393 document). However,
detailed regulation is established specifically for these vehicles in articles 166 and 167 of the
CAP393.
UAV that weigh more than 20kg are currently banned from flying in civilian airspace other than
in a large zone in west Wales and a smaller one over the military base at Boscombe Down.
UAVs that are less than 20kg (small unmanned aircraft) can fly in normal airspace for private use
as long as the operator is not planning to use data or images from the flight acquired by flying
close to people or objects. UAVs have to remain 150m from congested events or large assemblies,
50m from a person or building, and within visual line of sight (VLOS) (500m horizontally and
122m vertically). Flights beyond VLOS can be permitted but the operators need to demonstrate
they can fly the plane safely. Live-streaming from the UAV to the pilot is not considered a good
enough measure by the CAA to allow drones to be flown beyond VLOS. Anyone who is using a
drone under 20kg for commercial purposes has to be licensed to ensure that they are sufficiently
trained to fly the plane and have the appropriate insurance in place.
56
General guidelines to fly UAV for civilian applications in UK:
 Small UAV under 7kg can be flown exempt from any restrictive rules
 UAV under 20kg can be flown following CAA rules
 Fly inside visual line of sight (VLOS):
a) Vertically < 400ft (~122m) b) Horizontally < 500m
 Maintain a pilot in control, (ability to take manual control and fly the aircraft out of danger)
 Stay away from built-up or congested areas
 A permission from the CAA is required to:
a) fly for commercial use industry b) fly near congested areas
Currently, as of December 2014, with the rapidly growing interest in and expanding end-user
community, there is increasingly growing concern about the use of UAVs of any size in general.
Daily reports of accidents and near misses between drones and civilian aircraft has escalated
concern about the safety issues of these small aerial platforms, not so much for commercial
operators, but the growing number of individuals and hobbyists who clearly have no sense of the
danger and risk that carelessly flown UAV platforms, no matter how small can pose to people,
animals, installations, and now passenger airliners, aside from the security and privacy issues that
have been raised. Irrespective of whether or not these platforms are classed as toys or aircraft, all
platforms with or without sensors on board can pose considerable risk which ultimately will
probably lead to a requirement for not only extended guidelines for their safe and responsible
operation, but also training, retraining, and insurance.
4.6 UAVs and privacy
The potential uses for UAVs stagger the imagination. The units are relatively inexpensive, so the
possible pool of users is much larger than for conventional aircraft or helicopters that historically
have been used for aerial monitoring or photography. Drones can go many places a plane or
helicopter cannot, such as over fences and next to windows, and that ability raises serious privacy
issues. Intentions might not even be an issue: an agent using a UAV to take a panoramic video of
a listed property might find that he or she accidentally recorded a view of the neighbors inside
their home.
57
In 2013 and 2014, 15 states in the USA enacted laws relating to UAVs and privacy. Of these,
most initially focus on law enforcement drones. Eleven states (Alaska, Florida, Idaho, Illinois,
Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah, and Wisconsin) passed laws that
specifically require law enforcement to obtain a warrant before conducting a search with a UAV.
In Iowa, the state law also prohibits the use of UAVs to enforce traffic laws.
States also moved to protect individual privacy from private drones. Laws in Indiana and
Louisiana make it a criminal offense to use a UAV to monitor or photograph property without the
property owner’s consent. In Illinois and Tennessee, it is unlawful to use UAVs to interfere with
hunters and fishers. Idaho law allows a person to bring a lawsuit against one who uses a UAV to
photograph or record the person without his or her written consent, if the operator intends to
publish or publicly disseminate the photo or recording(Planners, 2015). North Carolina also grants
a private right of action to a person who is photographed without their consent by a drone operator.
In Oregon, the law allows an owner or occupant of property to bring a civil action against a person
who flies a UAV over the property at an altitude of less than 400 feet in certain circumstances.
4.7 Rules and regulations surrounding drone technology in Uganda
In Uganda at all aircraft machinery operating in Ugandan air space are subject to regulation by the
civil aviation authority of Uganda as stipulated by civil aviation authority act 1991 that states that
all aircraft operating in Uganda airspace, whether the aircraft is of foreign or Uganda registry, and
to Uganda aircraft operating outside of Uganda territory shall be subject to this act.
With that said, since drones are considered to aircraft that means drone activities in Uganda are
bound by this act. Therefore, a person with the intention of flying a drone should be in line with
this act. However, since drone technology is a new and emerging market in Uganda civil aviation
authority has not set up any regulations as of the time this research was carried out. This is because
civil aviation authority of Uganda subscribes to the international civil aviation authority
organization Chicago convention and as of the time this research was carried out plans for proper
integration of drones into the airspace was still in its infant stages.However, the international civil
aviation authority organization has set time lines for for integrating all drone classes: By 2018,
initial integration into non-segregated airspace (i.e. where manned aircraft also flies). By 2028,
full integration, i.e. so that drones can communicate with air traffic control
58
Procedure carried out before operating a drone in Uganda
 Every drone project should lay in a certain ministry. Therefore, permission for one to use
a drone is first sought from that ministry. For example, if a student wanted to fly a drone,
then he would seek for permission from Ministry of education and Sports.
 Then he would have to go to the highest security organ in the land which is the central
military Intelligence(CMI) at the headquarters of Ministry of Defense. He is then awarded
a letter that makes the security organ aware of his activities.
 He then proceeds to apply to fly the drone in Ugandan air space from the civil Aviation
authority.
 If accepted, he then proceeds to the area of interest and then seeks permission and letters
of acceptance from the local authorities like the police station or barracks in the area, the
LC5, LC3 and LC1 of the area.
Information to be availed to the various authorities
 Type and purpose of work to be done
 Duration of work
 Area of coverage of work
 Type of drone and equipment specifications to be used
 Information to be collected
59
5.0 CONCLUSION AND RECOMMENDATION
Introduction
The main objective of this research was to assess the applicability of drone technology in Uganda’s
construction industry. This chapter includes the conclusions, contributions and recommendations
that can bring forth drone technology to the construction industry. This research had 5 specific
objectives which were achieved through reviewing literature and data collection using interview
guides and participant questionnaires. The data collected was then analyzed in detail. The first
objective was to identify the activities drones can perform in the construction industry, the second
objective was to assess the economic impact drone technology would have on the construction
process, the third objective was to identify the rules and regulations surrounding the use of drone
technology in Uganda, the fourth was to identify the challenges facing applicability drone
technology in Uganda and the last was to suggest remedies and recommendations.
Conclusions
 It is an established fact that most construction professionals do not know about drone
technology being used in the construction industry.
 There are no proper and clear rules, regulations and registration procedures surrounding
the use of drone technology in Uganda.
 Most construction companies that have used drones in the construction process just hire
them for a particular task.
 Drone technology is mainly used in when inspecting and monitoring infrastructure
 There is limited skilled man power that can properly operate and process data from
drone technology.
 There is also limited access to spare parts and repairs for drone technology in Uganda.
The construction industry plays an important role in the economic contribution for the
development of the country. Therefore, incorporating drone technology would surely make
construction industry faster, easier and more accurate in order to carter for the ever increasing
demands laid upon it. Despite the increase awareness and use of drones in other sectors, the
government and professional bodies in the construction industry should come with more
mechanism to promote the use of drone technology in the industry.

  • 10. 10 1.0 CHAPTER ONE: INTRODUCTION 1.1 Background According to (Insurance Services Office, 2014), During World War II, the U.S. military endeavored to create an unmanned aerial vehicle. Reports indicate this military operation involved a B-17 bomber equipped with TV cameras, parachutes, and explosives. The plan was for the bomber pilot to take off, reach a designated altitude, and bail out, while a pilot in a second plane used remote controls to guide the highly explosive plane to its target. This mission met with little success with the pilot dying during the operation of the task. While unmanned aerial vehicles were only in their infancy during World War II, the efforts of the “greatest generation” helped lay the groundwork for today. Drones, or unmanned aircraft today have become an integral part of the U.S. military. People around the world are buying drones online and using them to take aerial photos or videos. (Overview, n.d.)Based on 2013 teal group analyzed that civilian application of drones was at 12% and predicted that it will be 30% by 2030.Businesses are integrating drones into their long-term strategies and considering potential uses. According to (Cossio et al., 2012) in agriculture, the association of unmanned aerial vehicles systems international (AUVSI) reports that over 100 drones are being used in china and japan to closely monitor crops to improve management and yields. The association also predicts that drones used for agriculture could comprise over 80% of future drone use. Mining companies are already deploying drones worldwide with great efficiency and safety gains to accurately measure site conditions, inspect pit walls, calculate quantities, and measure and map in 3D. Photogrammetric techniques are used for 3D modelling however more precise laser LiDAR sensors for UAV platforms will be developed in time(Raja, n.d.). Monitoring from above of construction project sites provides a new input during all phases of a project lifecycle. Aerial photography is currently used on only the largest projects but this will change in the future as costs reduce. The ability to quickly model from above in 3D with increasing precision will provide a check on projects compared to plans, as well as the better coordination of materials on the job site. Monitoring activity across a large, complex construction site is
  • 11. 11 particularly difficult because there are so many moving parts, and because the jobs being performed change frequently. A report published in 2009 by the National Research Council of the National Academies found that construction lags behind other industries such as manufacturing in terms of productivity, and blamed the situation on problems with planning, coordination, and communication. The Inspections, from pipelines to power lines to towers, to processing plants, the inspection of complex infrastructure will benefit from regular aerial monitoring. The ability to sense in three dimensions, take thermal readings, and to detect metal strain will greatly improve infrastructure inspection (Cossio et al., 2012). 1.2 Problem Statement The Construction Industry is growing and under ever more pressure to reduce costs, increase quality, reduce work time and environmental impact. Inspection, monitoring and surveying on large construction projects are very intense, expensive and time consuming activities. This is especially so for road, railway and pipe line construction projects where surveying, inspection and monitoring costs are high, efficient monitoring is difficult due to the longevity of the structures. In tunnel and bridge construction workers are told to inspect in very dangerous and unhealthy conditions. According to (Irizarry, Gheisari, & Walker, 2012), the construction industry is one of the most dangerous industries in the world with a fata rate of 9.5 per 10,000 full time workers. There is also an increasing demand for real time inspection, monitoring and data processing imagery to develop more accurate and reliable 3D images. On the other hand drone technology has developed beyond military use and various civilian applications have started to be incorporated into the society. In the construction industry the use of unmanned aerial vehicles can make inspection, monitoring and surveying on large construction projects faster, less costly, safer, more reliable and accurate. 1.3 Main Objective Is to assess the applicability of drone technology in Uganda’s construction industry.
  • 12. 12 1.4 Specific Objectives 1. Identify the activities drones can perform in the construction industry. 2. Assess the costs involved in using a drone to perform the activities. 3. Review the rules and regulations surrounding the use of drone technology in the construction industry. 4. Identify the challenges facing the use of drone technology in the construction industry. 5. Assess whether drone technology can be adopted in the construction industry. 1.5 Significance of Study  The study and research findings will help to policy makers or implementers in Uganda to understand drone technology, their relevance in the construction industry and their significance in addressing the issues involved in monitoring, inspection and surveying.  The study will create awareness to the public about the existence of drone technology and the advantages of acquiring one.  The researcher seeks to help students in the related field to benefit from the findings and also give room for more research in same field of drone technology 1.6 Scope of study 1.6.1 Academic Scope This research is to concentrates on the drone technology, what activities they can do in construction and also embodies the rules and regulations surrounding the use of drones and economic impact in terms of costs involved in their use. 1.6.2 Geographical Scope The geographical scope is to base in Uganda. The study will be looking at the large construction projects that are taking place all over the country that may necessitate the use of drone technology. Particular emphasis will be placed national roads, the Uganda section of the Uganda-Kenya standard gauge railway 1.7 Justification of the Study There is hardly any literature discussing the impact of drone technology on the construction industry in Uganda. There is also a misconception about drone technology as only military based.
  • 13. 13 Unlike previous worldwide researchers, this particular research will focus on what activities drones can do in the construction industry, their economic and social ramifications and whether they can be integrated into the country’s construction industry.
  • 14. 14 2.0 CHAPTER TWO: LITERATURE REVIEW Introduction This chapter provides an insight into the history unmanned aerial systems, their evolution, definition, types and why they are needed. 2.1 Definition of Drones (Industry, 2014), A drone is an aerial vehicle which does not have an on board pilot. They are officially known as UAV’s (Unmanned Aerial Vehicles). They have been brought into public attention due to their uses in recent military operations, though their civilian use has been going on since the 90’s, mainly in agriculture. (AIS, 2013),Defined by the U.S. Department of Defense as “an aircraft or balloon that does not carry a human operator and is capable of flight under remote control or autonomous programming,” 2.2 Drone Companies From commercial drones for civil applications to military unmanned aircraft, this selection of game changing companies reveals the potential of the very fast growing drone market. The selected companies are based all around the world, with a focus on Europe and France(Agarwal, Mohan, & Kumar, 2014). 2.2.1Titan This company founded in the USA in 2012 and mainly deals with constructor clients. Titan has developed a solar powered drone that can navigate for up to three years at a twenty kilometers altitude. The drone is 15 meters long with a 50 meters wingspan. Google bought Titan in April 2014, and could use its drones to enable Internet access in remote areas, in addition to taking high-quality images for Google maps. Facebook had allegedly entered into discussions with Titan a few months before its acquisition by Google.
  • 15. 15 2.2.2Delta This is a company that was founded in France in 2011. It mainly has constructor clients with a head count of over 30 employees and an investment of over 3.9 million pounds. By 2013 the company had turnover of over 696,000 pounds Delta Drone has developed two drones: one with a fixed wing, the other with a rotary wing. The main focus is inspection, but the drones can also operate in sectors such as agriculture or geology. The company offers both a renting model and a service model. It has created the Ecole Française du Drone , to train drone operators. Unlike its competitors, Delta Drone has decided to go public very quickly, and has been listed on Alternext since June 2013. 2.2.3 DJI This company was founded in china in 2013 with over 800 employees and turnover of $131m The star product of DJI is the Phantom, a mass market drone launched in January 2013, and available from $500 (without the camera). The company has grown its sales very quickly, with an average of 20,000 units per month since its launch, and is now Parrot’s most serious challenger on the market. DJI has released a second version of the Phantom in December 2013. The Phantom now starts to be used for surveillance and film-shooting purposes. 2.2.4 Parrot Founded in 1994 by Henri Seydoux, Parrot has been widely investing in the drone sector since 2010, and has become a global leader in drones with its famous A/R drone - until the arrival of DJI on the market. The company strategy is to accelerate its sales in the market by launching new products and enhancing its distributors network, while developing its business (which represented 15% of 2013 turnover). 2.2.5 Sense Fly This company was founded in Switzerland in 2009 with a financing of over $4m and a turnover of $6.3m by 2013. The main product of Sensefly is a fixed wing drone called the eBee. Its applications range from agriculture (monitoring of crop health, with a dedicated sensor developed by Airinov) to 3D mapping (via a software developed by Pix4D, another Parrot subsidy). More than 500 drones were sold in 2013, at a price around €15k. Parrot took a majority share (56,6%) in Sensefly in July 2012
  • 16. 16 2.2.6 Airinov This company was founded in France in 2010 with over 10 employees and financing of $ 1.6m. With the help of INRA, Airinov has desiged a sensor that analyzes the reflection of the sunlight on the plants, so as to estimate the crop health. The data is then analyzed in a dedicated software. The sensor is implemented in Sensefly’s eBee . Parrot took a minority stake in Airinov (20.9%) in February 2014. 2.2.7 Gimball This company was founded in Switzerland in 2014.Gimball aims to operate in inaccessible places. The drone can navigate close to infrastructures, since it will not be damaged if hitting an obstacle thanks to its spherical carbon fiber protection. It can be used for inspecting tunnels, power plant boilers, wind turbine blades, etc. The drone also has a strong potential, since it is less dangerous than usual drones. 2.2.8 Novadem This company was founded in France in 2006 Novadem is a French company specializing in rotary winged drones. It has developed three drones for three specific markets: military, inspection, and photo/video. One of Novadem’s drone’s advantages is that they can be easily folded, which is key forthe military market in particular 2.2.9 Tech Ject This was founded in USA in 2012.Techject has gained a lot of visibility with its Dragonfly drone, which was originally financed through a $1m grant from the US Air Force, and then with a Indiegogo campaign that helped raise more than $1m. The drone is 15cm long and imitates the fly of a dragonfly, with flapping wings, which allows it to be used in spying and security scenarios. The drone is the result of four years of R&D at Georgia Tech. A similar approach has been taken by the American company AeroVironment ($250m of turnover), with its Hummingbird drone. 2.2.10 Red Bird This company was founded in France in 2013 Redbird is an operator. The company does not manufacture drones, but it flies them. Among the drone constructors supplying Redbird are DelairTech and Gatewing (fixed wing), MicroDrones (rotary wing). Missions include inspection
  • 17. 17 of transportation networks, mines and quarries, realization of 3D maps (photogrammetry), surveillance, etc 2.2.11 Photo Kite This company was founded in Switzerland in 2014. Photo kite offers a different approach to the drone market. Considering that flying a drone is a rather complicated task, requiring usually hours of training, photokite has developed a drone attached to a tether, hence very easy to operate: the user orientates the drone, turns it on, and then releases it; he can move the drone with the tether, just like he would do with a dog - or a kite. Other than photo/video usages in the B2C market, photokite has applications in the B2B Market: photo/video journalism, inspection. 2.2.12 General Atomics This company was founded in the USA in 1955 and now has financing of over $2.4bn. General Atomics is an American defense contractor. Its MQ1Predator drone is one of the most famous military drones, and has been used in many exterior operations by several armies. It is 8 meters long with a 17 meters wing-span, and its max endurance is 40 hours. The following version, the Predator B, has been sold to the American, French, British and Italian armies. The Predator C is currently under testing. 2.2.13 Cymber Hawk This company was founded in Scotland in 2008. Cyberhawk drones conduct close visual and thermal inspections of industrial assets both on-shore and off-shore such as flares, wind turbines and utility transmission towers. Using a drone to realize such hazardous tasks means that the infrastructures do not have to be shut down during the inspection, which allows to realize important savings. Cyberhawk’s clients are mainly oil and gas companies, such as Exxon Mobil, Shell, Total and BP. Cyberhawk raised £1.25m in June 2013, so as to accelerate its growth and enter new markets. 2.2.14 Micro Drones This company was founded in Germany in 2005.The star drone, the md4-1000, has a flight time of up to 88 min. and a payload of 1200g. It can be used for security, surveillance and inspection. The German police, as well as the Swedish and Chinese police, are among its clients.
  • 18. 18 The company has sold more than a thousand drones, and focuses on expanding its resellers network. Micro drones also distributes the PIX4D software (in which Parrot has invested in July 2012) to complete its off 2.3 Types of Drones There are so many types of civilian drones on the market. Civilian drones now count for 70% of all manufactured drones in the world(Babel, President, Risk, & Consultant, n.d.). Some of them include the following; 2.3.1 DJI Phantom 3 and Phantom 2 Series One of the best drones for sale right now is the Phantom 3. Here are some of the features that make the Phantom 3 my favorite drone.  4K Video with 12 Megapixel Photos  Live HD Video streaming to your mobile device (can also stream to YouTube)  Powerful Mobile App (just like the DJI Inspire)  Faster Charging Battery Charger  Advanced Vision Positioning for Indoor Flight  True 20-minute flight times.  Free In-app Flight simulator for learning to fly. By the time the research was made the Phantom 3 was priced at $1259 the Phantom 3 for the easiest drone to fly with the most flight time, features and great video quality, the Phantom 3 is the only option that one would recommend to just about anyone. There are a few other drones that have similar functionality to the Phantom 3. The Phantom 3 comes in four different models. At the top of the food chain, DJI’s Phantom 3 Professional comes standard with follow-me, GPS waypoints, point-of-interest, optical-flow and ultrasonic sensors (for height and position hold when no GPS signal is available), 4K video recording, 20-minute flight times and more. The Phantom 3 Advanced will do everything that the Phantom 3 Professional can do, but at 1080p instead of 4K. At $700, the Phantom 3 Standard is the cheapest Phantom 3 you can buy. It has a cheaper controller design (taken from the older Phantom 2), no optical-flow or ultrasonic sensors, but it still has follow-me, GPS waypoints and shoots 2.7k video.
  • 19. 19 With the Phantom 3 Standard, you’re basically getting something comparable to a 3DR solo with a GoPro Hero 4 Silver and gimbal for less than half the cost. The last model which came out a few weeks ago is the Phantom 3 4K. It has a lot of great features like 4K but at the same price as the Phantom 3 advanced. Figure 1 DJI Phantom 2 Figure 2 DJI Phantom 3 2.3.2DJI Inspire 1 & Inspire 1 PRO w/ 4K video The DJI inspire 1 is the most professional ready-to-fly drone one can buy. It is probably one of the most advanced quadcopters. The Inspire 1 comes standard with all of the features of the Phantom 3 Professional, but with a much bigger and higher quality design. It's almost twice as big and twice as fast as the Phantom 3 and with its transforming design, the propellers will almost never be seen in your videos. Additionally, the Inspire 1 comes with a 4K camera on a 360 degree panning gimbal, which means that one can control the motion of the camera completely independently of the Inspire 1. This makes it great for dual pilot operation, but also for getting locked in shots in almost any wind conditions. For Professional video use, the Inspire 1 comes in two other variants with superior Image quality to even the most expensive aerial platforms in it’s size. If one need a high quality camera for shooting pro quality video The Inspire 1 pro is a version of the inspire 1 that features a micro-four- thirds 4K camera with 13 stops of dynamic range, interchangeable lenses and a sensor that’s 8 times larger than the standard Inspire 1 camera. The inspire 1 costs about $2900 and is mainly for people who want an amazing tool for aerial photography, videography, search and rescue, 3D mapping, or any other professional application.
  • 20. 20 Figure 3 DJI Inspire 1 Figure 4 DJI Inspire 1 2.3.3 Yuneec Q500 4K Compared to DJI and 3D robotics, Yuneec is a relatively unknown company, however that hasn’t stopped them from competing. The q500 4K is the newest model from Yuneec and as the name implies, it shoots 4K video just like the Phantom 3 and Solo. It has lots of great features for the price. For example, it comes with two batteries and a hand mount that allows you to take the camera (and gimbal) off the quadcopter to use it as a mini handheld stabilized camera system. $1300 is cost of Q500 4K. Because the Q500 4K isn’t super popular compared to the other models, one will not find a lot of information and videos about it yet, nor will there be any third-party accessories available. The most interesting feature of the Q500 4K is that it has a android device built into the controller, so there’s no need to use your tablet or smartphone, although the quality of the screen on the controller is definitely subpar compared to an iPad. Figure 5 Yuneec Q500 4K Figure 6 Yuneec Q500 4K
  • 21. 21 2.3.4 3DR Solo The 3D robotics Solo is extremely functional and easy to use. It has many features similar to the Phantom 3 but instead of using a built-in camera, it uses the GoPro Hero 4. This means that you have the ability to take the camera off and use it for whatever you want. The biggest difference between the Solo and almost any other ready-to-fly camera drone is that it’s modular/upgradable but still easy to use. It has a gimbal bay and an accessory bay, meaning that third-pardy companies can easily make new gimbals along with other accessories. One can get the Solo for only $999, however this price does not include the GoPro or 3 axis gimbal. If one wanted to get the Solo with the 3DR gimbal and a GoPro Hero 4 Black Edition, the total cost will be around $1900. Figure 7 3DR Solo Figure8 3DR Solo 2.3.5 Hubsan X4 The Hubsan X4 is about the same size as the Nano QX, but roughly half of the price. There’s 4 different versions of the Hubsan X4. The cheapest version is about $45 USD (including the controller). It doesn’t have an Agility mode like the Nano QX so you can’t fly with complete manual control, but it’s pretty fast and maneuverable (even with auto leveling). It also has 6 LED lights which can be turned on and off from the controller. Speaking of controllers, the controller that comes with the 3 cheaper Hubsan models is actually pretty nice. The next 2 versions of the Hubsan X4 have cameras. They’re slightly bigger and heavier than the cheaper version of the X4, but the flight time is about the same. The H107C is the version with a standard definition camera and the 61170-02 is the one with a 720p camera. The only problem with the HD version is that it’s more expensive and the flight time is slightly less.
  • 22. 22 The most expensive version of the Hubsan X4 is the H107D. It’s mainly for FPV, which allows you to see everything that the drone can see in real time. The design is slightly different from any of the other models and it has a black antenna on the bottom. Figure 9 Hubsan X4 Figure 10 Hubsan X4 2.3.6 Blade Nano QX The nano QX is a lot like the LaTrax Alias but smaller. Because it’s a few inches smaller than the Alias it doesn’t have as much authority. It has two flight modes, stability and agility. In agility mode, you have full control over the quadcopter to learn how to fly manually (it will not auto level itself). In stability mode, it will automatically level itself when you let go of the controls. The nano doesn’t have the auto flipping functions that the Alias does. Since the Nano QX is smaller than the Alias, it’s only $90 instead of $150. One of the major problems about having a smaller quadcopter like the Nano QX is that it’s harder to see when flying far away, so it’s easier to lose orientation.

  • 23. 23 2.3.7 Parrot Bebop The Parrot Bebop is one of the more technologically advanced drones for sale right now. It’s the AR Drone’s smaller, smarter, faster and more expensive little brother. Just like the AR Drone, you can control the Bebop with your iPhone or Android device. But with the Bebop, there’s an optional Sky Controller which will allow you to have real joystick controls, extended range, HDMI output and a few other cool things. The Bebop has a lot of improvements over the AR Drone 2.0, but the most interesting feature is the video system. It has a 14-megapixel camera with a 180-degree field-of-view fisheye lens. Since the camera lens has such a wide field-of-view and a really fast processor, the Bebop is able to take the full 14-megapixel image, fix the image distortion (eliminating the fisheye effect), stabilize the image, then send the live video back to your phone. What all that means is that you’ll be getting a digitally stabilized standard definition video feed straight to your phone. At the same time, It also records digitally stabilized 1080p video to the 8GB of onboard memory. The price for the Bebop is $499 USD and you have to use your smartphone to fly it, which means that you won’t have precise controls unless you buy the optional $400 Sky Controller (making it $899 USD total). Figure 13 Parrot Bebop Figure 14 Parrot Bebop 2.3.8 Tbs Gemini The TBS GEMINI is a tiny little hex copter designed specifically for FPV (first person view) racing. It’s actually one of the only FPV racing drones for sale that comes ready to fly.
  • 24. 24 The first thing that one would notice when watching videos of the GEMINI is the fact that it hovers with the nose tilted up. This is because all of the motors are tilted forward by about 10 degrees. Doing this will actually improve the performance of the drone by decreasing drag and increasing speed in forward flight. Another cool feature of the GEMINI is the modular design. If one was to look on the inside of this little hexacopter, you would notice it’s not like a typical hobby grade drone. Like the QAV400, the GEMINI isn’t for everyone though. It’s mostly intended for people who want to get into the hobby side of drones and just want something really small and fast for FPV.As far as price goes, it’s about $600. Availability for the GEMINI is pretty good, so one shouldn’t have a super hard time getting it. Figure 15 TBS Gemini Figure 16 TBS Gemini 2.3.9 3d Robotics Iris + Out of all the drones for sale, (other than the AR Drone) the IRIS has the biggest list of features. In a nutshell, the IRIS is for people who have never owned a drone before, but want something that they can tinker with and modify. It has a lot of auto-pilot features such as auto takeoff and landing, GPS waypoint flight (with a computer or android device), live data telemetry and more. You can also order the IRIS with a brushless gimbal for the GoPro (made by a company called Tarot) for shooting aerial video. The IRIS is an interesting quadcopter, especially for people who want to learn about flight controllers and how auto-pilot systems work. It costs about $750.The iris is also not that user friendly.
  • 25. 25 Figure 17 3D Robotics Iris + Figure 18 3D Robotics Iris + 2.3.10 3d Robotics X8+ The 3D Robotics X8+ is like the tank of ready-to-fly drones for sale. it has 8 motors that turn large 11 inch propellers. With all that power, it's able to lift over 800g (about 2 pounds) of payload, making it a great option for lifting large cameras and LIDAR systems. Basically, the X8 is like the bigger brother of the IRIS. It has the same flight controller, but the electronics are just bigger and better. One good thing about having 8 motors in this configuration, is that you get extra redundancy. For example, one motor could completely shut off and the drone would still hover in the air without any issue. Another feature that both the X8+ and IRIS+ have is the popular "follow me" feature that everyone talks about. In this mode, the drone will try to follow you around by getting GPS position information from your smartphone. Figure 19 3D Robotics Iris X8 Figure 20 3D Robotics X8 +
  • 26. 26 2.3.11 Quanum Nova If you’re on a budget and want a lot of features for your money, the Quanum Nova is probably the best option. It has a similar shell design to the DJI Phantom 2, but it’s running the same software as the 3D Robotics IRIS, which means that it has almost all of the features of the IRIS (with the exception of data telemetry) at a fraction of the cost. The Quanum Nova is only $300 which is very low for what it can do. One has to buy the battery and charger separately, but even when adding that to the full cost it would only be about $400 for everything ($350 less than the IRIS). Just like the IRIS, the Nova also has an optional brushless gimbal for the GoPro that costs $100 extra. The main thing to take into consideration with the Quanum Nova is that it’s a very cheap quadcopter. Figure 21 Quannum Nova Figure 22 Quannum Nova 2.3.12 Latrax Alias If one wanted to learn how to fly a quadcopter manually, the LaTrax Alias is a great way to start. The reason why it’s a good quadcopter to learn with is because it has a full manual flight mode and it’s extremely durable. This means that you can learn how to fly without worrying too much about crashing. Since it’s about 7 inches wide and has big propellers it also has great authority, so doing bank turns, pirouette maneuvers and more would be no problem. It’s also big enough to carry a small camera like the 808 keychain camera. People install video transmitters and do FPV. The Alias costs around $150.
  • 27. 27 Figure 23 LaTrax Alias Figure 24 LaTrax Alias 2.3.13Parrot AR Drone 2.0 When the AR Drone 2.0 first came out, it was one of the coolest drones for sale on the market. It has a 1GHz 32 bit processor, 1GB of ram, gyros, accelerometers, magnetometers, a pressure sensor, an ultrasonic sensor, 2 cameras and more. Even though it’s over 2 years old, the AR Drone is still one of the most advanced quadcopters available in its price range which is $299. The biggest feature of the AR Drone is that it can be controlled from your iPhone. One can also see a live video feed from the phone screen and record video. It’s even running Linux and there’s an AR Drone open API platform, so you can program it to do whatever you want.The AR drone can only be controlled with your phone, meaning that you can’t use a normal RC controller with real control sticks. That also means that there’s no way to fly manually. Figure 25 Parrot AR Drone 2.0 Figure 26 Parrot AR Drone 2.0
  • 28. 28 2.3.14 QAV400 The QAV400 is a quadcopter designed for sport flying and FPV (first person view). It’s actually just a frame that’s sold so people can add their own electronics to it, but you can get a ready-to-fly version with all of the electronics installed if you’re willing to pay extra. The feeling you get when flying FPV with this quadcopter is absolutely amazing. That being said, I wouldn’t recommend buying anything like this unless you already have experience with RC planes or helicopters. This is truly a hobbyist type of multirotor and all of the parts and components are high quality, customizable and made by completely different companies. So getting it set up and fixing it when you crash would be a lot harder than most of the other ready-to-fly options out there. The price for this quadcopter is $970 which is normal for ready-to-fly multirotors in this category. Figure 27 QAV 400 2.3.15 Proto X The Proto X is one of the smallest drones for sale on the planet. It has 3 gyros, 3 accelerometers, 4 motor speed controllers and a radio receiver all shoved into a tiny PCB board about the size of a quarter. The price for this little drone is only about $38. It’s one of the cheapest quadcopters you can buy (but cheap isn’t necessarily a good thing). It’s very fast for how small it is, but at the same time since the rotors are so small and close together, people have found that it’s a bit hard to do bank turns with it. Since the Proto X is so cheap, there is a chance that you could buy a defective one, but you can always just send it back.
  • 29. 29 2.4 Classification of Drones According (Juty & Morris, 2015),The definition of UAVs encompasses fixed and rotary wings UAVs, lighter-than-air UAVs, lethal aerial vehicles, decoys and targets, alternatively piloted aircrafts and uninhabited combat aerial vehicles. Unmanned aerial vehicles can be:  Remotely piloted aircraft (RPA) controlled from the ground.  Autonomously controlled by on-board computers.  Pre-programmed to fly specified routes. According to (PeterWijninga, Sijbren de Jong, 2015), drones can be classified under three major categories, 2.4.1 Class III These are drones that have a weight of over 600kg. The class iii drones come in three different types, UCAV, HALE and the MALE. The UCAV is basically a military, combat and tactical strike drone. It has an average elevation of 20km.the drone is usually used to an unlimited line of sight. They use an acquisition, target and designation sensor suite. Examples of these drones include Pegasus, Phantom Ray, nEUROn, Skat, AURA. Currently they are not being used for any civilian applications. The HALE is used for strategic and national observation during military surveys. It also has an average elevation of 20km. the drone is also used for an unlimited line of sight. They use SAR/MTI sensor suite. These drones are also used real time imagery of large geographical areas. Example of this type includes the global hawk and the Euro hawk. The MALE, this is also used for strategic and national observation during military surveys. It is very similar to the HALE. The only difference is its appearance and that it uses a ground search radar and laser range finder as the sensor suites. 2.4.2 Class II These are drones that basically are in the weight of between 150-600kg.In the military they are used for tactical observation and strike operations. They can fly up to 3km in the air and have a
  • 30. 30 200km line of sight. Some civilian applications include real time high precision imagery of geographical areas. Examples include sperwer and aerostar. 2.4.3 Class I These are drones that weigh below 150kg. they come in three versions; small, mini and micro drones. In the military they are used for tactical individual observations. They can fly up to 1km in the air. Examples of these include black hornet, scan eagle, raven and aladin. 2.5 Evolution of Drones According to (AIS, 2013)Unmanned systems have been in use by American armed forces since 1917, when the Kettering Aerial Torpedo flew using preset pneumatic and electrical controls. Radio control technology enabled the use of pilotless flight in both world wars on a limited basis, and improvements in altimeter, gyrocompass and guidance technology led to increasing deployments during the Vietnam era. From 1964 to 1975, the U.S. Air Force flew 3,435 reconnaissance drone missions over North Vietnam and its surrounding areas, and lost 554 UAVs during the conflict.9 With the advent of GPS technology, stealth-based three-dimensional thrust vectoring flight control [jet steering], and advanced avionics, UAS entered the modern age in the late 1980s, when they were effectively deployed for reconnaissance by the Israeli Air Force, and later by the United States in the Balkans. In 1999, the United States flew 100,000 flight hours with unmanned systems. Today, the United States flies more than 1 million unmanned flight hours annually, and the Department of Defense operates more than 7,000 UAS. The growth of unmanned systems for military and civil use is projected to continue through the next decade. It is estimated that UAS spending will almost double over the next decade, from $6.6 billion to $11.4 billion on an annual basis. 2.6 Factor to Consider Before Using a Drone There are a range of factors to be considered when specifying an adequate unmanned aerial system for a certain application. Some general considerations whilst others are dependent and relative to the final purpose of a particular task the UAV must perform. The most relevant factors to account for when choosing a UAV system are listed and briefly described below.
  • 31. 31 2.6.1 Flying Time, Distance, and Area Coverage The extent of the area to survey is crucial for selection of an adequate UAV, capable to cover the area in a reasonable time and with affordable power consumption. Among N-rotor platforms, DJI claims that the Phantom Quadcopter can fly at horizontal speeds of 10 meters per second (36 km per hour). However, given the battery life and energy required to travel vertically, it is not possible to fly more than 2-4 kilometres from the ground location origin. The maximum vertical speed is 6 meters per second, meaning it can rise to 30 m in as little as 5 seconds! 2.6.2 Flying Height and Ground Control Realizable flying heights for UAVs depend very much upon the type and size of the platform, the ‘fuel’, and the means of control. In the case of large drone-based systems the flying height can be over 9000 m. Some small platforms can climb to 600-700 m although most are restricted by the control unit typically to heights below 400 m, when the control signal is lost. Generally small platforms do not need to fly at such high altitude: for small area surveys where high resolution imagery is required, the flying height may be only around 5-10 metres. For example, in order to achieve 3.3 cm Ground Sampling Distance (GSD) imagery, a UAV may only be required to fly at 100 m high. As the flying height increases, the area coverage increase, and the image resolution decreases, depending on the camera resolution. 2.6.3 UAV Altitude Control The flying height of a UAV depends on the characteristics of the platform and mission, but is determined in particular by the propellers and the payload. Maximum flying time decreases when flying height increases. Because the rotors spin faster to get higher altitude, the motors and the entire system become hotter during the high flights. There is a noticeable decrease in performance when going higher than 3000 m above sea level. However, this is unlikely to be a problem in the UK where 400 feet is the maximum permitted flying height. 2.6.4 Manual and Automated Launch / Landing Many small UAVs (e.g. N-copters) can take-off and land on the ground with or without the aid of a landing pad. Some can also be hand launched and landed, making them very flexible and easy to use. Larger and more sophisticated UAVs (N-rotor or fixed wing) require some form of launching device to facilitate the take-off of the platform. These pieces of kit are additional equipment that makes the logistics of the mission less easy and flexible. Safe retrieval is important and whilst
  • 32. 32 many platforms can be easily landed in areas of grass or bushes, this is not always possible. In order to prevent damage to the sensors and aircraft, recovery options including parachute and homing systems have been developed for recovery. 2.6.5 System Failure and Retrieval System failure is not impossible or unlikely, and whilst most UAV platforms are now ReadyTo- Fly (RTF) systems, problems can arise including rotor failure, fly-aways, and motor malfunction amongst other things. Depending on the severity of the problem, UAV platforms could be destroyed or damaged beyond repair together with the on-board sensors and electronics. However, most UAV kit is built robust, and both easy and cheap to repair. Operators should have ready to use spares (e.g. rotors, nuts, bolts) and ensure rigorously conducted thorough checks of the system and platform prior and in between each flight. 2.6.6 Flying Conditions Most UAVs are restricted by the environmental flying conditions they can operate in. As most platforms are not waterproof, this means that for the most part these platforms and their sensors cannot be flown in anything other than dry conditions, especially for most electric powered UAVs. If a UAV gets caught in the rain it is generally best to land as soon as possible. 2.7.7 Mission Planning Mission planning software (http://ardupilot.com/downloads/?did=82) is now widely available providing the basis for small UAV platforms to fly fully autonomously. Increasingly these are designed to be plug and play and can be determined using waypoints ‘on the fly’ or via pre- planning for an aerial sortie. Many e.g. Mission Planner and Droid Planner (see section 3.3.2 in this report) arewidely available for use on tablets and smartphones and can be used to plan repetitive and large area coverage flights for N-copters and fixed wing UAVs. 2.6.8 Operation and Control In the past, most radio control model aircraft required considerable skills for launching, flying and landing and was regarded as a specialist activity. Today, part of the attraction and rapidly growing use of the small UAV platforms has been driven by developments in the technology allowing virtually anyone to fly – with a shallow learning curve –small quadcopters, and more recently the autonomous fixed wing aircraft increasingly used for aerial survey work. These days many popular
  • 33. 33 UAVs come ready to fly, the platform can fly in an autonomous mode in which the aircraft is guided via GPS to pre-programmed waypoints. RTF aircraft can easily be flown horizontally and vertically along a flight line using a monitor or goggles which display the view over which the UAV is flying, and include altimetry, battery power and other useful parameters. Simple radio- controlled hand-held controls, operating in the 36 MHz band or the 2.4 GHz bands, with Mode 1 and mode 2 controls – left and right joysticks – allow the UAV to be controlled easily. 2.6.9 Digital Image Processing Software The photography acquired by UAVs can be visually interpreted with aerial photo-interpretation techniques. Digital Image Processing (DIP) software, much of it now low-cost, can also be used to geo-correct and mosaic the photographic prints or images together as the basis for onscreen interpretation and the mapping of thematic information for subsequent input to a GIS. The lower cost of PCs and accompanying hardware (e.g. storage media, scanners, printers and software) provides opportunities to capture, store, process and map the data in-house on a regular basis. Digital image processing (e.g. geometric and radiometric corrections) can be performed with standard or specialized DIP software. Furthermore, there is now a small range of UAV dedicated software packages available specifically aimed at UAV image acquisition and correction, which have similar functionality and better price. A few examples of UAV dedicated software are listed below: Pix4D, Mosaic Mill, AirPhotoSE, Agisoft Photoscan Pro.

It includes the research design, targeted population and sampling techniques used, the research methodology, how the field study was carried out, how data was collected. 3.2 Research Design Both quantitative and qualitative methods of data collection was used to measure the answers to questions of better relationships and variables that can be obtained mathematically for explaining purposes, predicting and controlling phenomena whereas qualitative methods were used to answer questions about the complex nature of phenomena with the purpose of describing and understanding the phenomena from the respondent’s point of view 3.3Study Population The study population was selective. It comprised of country’s construction companies and consultants with particular emphasis given to those have engaged themselves with drone technology. 3.4 Research Tools This research involved various techniques which included: Interview guides, these were used for interviewing and liaising with different drone operators and service providers to establish the costs involved in the use drone technology. These interview guides were used with various construction companies and consultants to acquire information about drone technology awareness among the construction professions and the reasons why they think drones have not been used by construction companies. Interview guides were also used to identify the rules and regulations surrounding the use of drone technology in Uganda. 3.5 Sample Design (sampling techniques) This research adopted a non-probability sampling technique. Purposive and convenience sampling were used to generate a respondent list. This is because samples consisted of individuals considered to have knowledge and information drone technology and those that were easy to reach and acquire information from.

Great effort and analysis went into designing the guides. Meetings with university supervisor were conducted to identify the right questions required and to present them in a clear and an unambiguous format. Special care was also taken into phrasing the questions in a language that is easily understood by respondents. Content of Interview Guides Interview guide 1 as shown in Appendix had nine questions which addressed the rules and regulations surrounding the use of drone technology. This guide was particularly directed to the civil aviation authority as it’s the organization with the mandate to regulate any flying machine over Ugandan air space. The questions targeted their role as regards to drone technology and whether they had any regulations that they use to control drone activity in the country. The interview also looked at whether there is need for one to register his/ her drone before using it. The interview also contained questions pertaining the right procedure one needs to go through before using his/ her drone for a particular activity. Interview guide 2 as shown in the Appendix had 14 questions which addressed the objectives 1 and 2 of the study. The interview was directed mainly to companies and construction professional that have used drone technology before. The questions presented to the respondents were meant to capture their experience with drones, the activities they used them for, the reasons why they opted to use drone technology and at what cost. Interview guide 3 as shown in the appendix had 6 questions which addressed the main objective of the study. The interview was directed to construction companies, consultancies that have not used drone technology before. The questions targeted their awareness of drone technology, reasons why they have not incorporated drone technology in their works and if they believe drone technology can improve their monitoring, inspection and surveying techniques.
  • 36. 36 3.8 Data Collection In the context of this research, interviews guides were adopted to investigate existing rules and regulations surrounding the use of drone technology, the activities drone are doing in the construction industry and the economic impact drone technology introduces to the construction process. The interview was considered a suitable process of data collection that is capable to provide rich information. This research used unstructured interviews to stimulate discussions and breakdown any barriers between the interviewer and interviewees. Interview guide 1 was used to interview the air rules and regulation manager at the civil aviation authority. All questions in the guide pertaining the legislation of drone technology were answered clearly. 42 interviews were carried out in the investigation of activities drones can perform and economic impact drone technology introduces in the construction industry. 10 companies that have ever used drone technology were interviewed by the researcher. 26 companies that had no incorporated drone technology in their works were also interviewed by the researcher. The interviews were conducted with various construction professionals and managers within the companies. The respondents were very cooperative and willing to give information although information pertaining the costs and maintenance of the drones, the respondents readily willing to give the information. The interviews were then grouped according to the professions of the various respondents. Telephone call and online chats were carried out with 6 drone manufacturing companies. These companies were mainly based in the Europe and United states of America. The response to this method was good as all information pertaining drone specification was acquired with additional brochures also provided to the researcher for further information. The raw data was edited for missing data, double entry answers and other ambiguities.
  • 37. 37 3.9 Challenges Faced During Data Collection  The time factor was of one of the biggest challenges. The researcher found most his desired respondents having busy schedules. This made it a little difficult for the researcher to get detailed information about drone technology.  The financial aspect may also be a limiting factor. Money needed to access the drone service providers and the drone equipment may be financially straining.  Most of the respondents were not willing to give information pertaining the cost involved in the use of drone technology.  The researcher found it difficult to get enough information about the use of drone technology since few construction companies and consultants within the country have used drones in their construction process. 3.10 Data Quality Control. Drawing upon the strengths of the different methods employed in collection of data, the validity and reliability of the research is ensured since the questioners were brief and with clear questions, interviews were with willing parties and observations discreet to improve the quality or validity of the data.
  • 38. 38 4.0 RESEARCH FINDINGS AND DATA ANALYSIS 4.1 The Activities Drone Technology Can Perform in the Construction Industry of Uganda Applications are often focused on the military areas, surveillance, inspection of transmission lines and power distribution; low cost filming and panoramic picturing for the movie industry, sport events, crop and herd monitoring, among others(Gomez & Green, 2014). In construction various application of drones are being utilized as the following would show. 4.1.1 Unmanned Aerial Vehicles Used for Monitoring Site Safety UAVs will be able to provide real-time visual information to monitor construction site safety. As noted by (Gheisari, Irizarry and Walker 2012), in a constantly changing construction site the safety manager’s job of direct observation site work and interaction with workers continuously and in real-time are an excellent application for UAVs. UAVs have the ability to reach difficult positions on a construction site and provide live video streaming for safety managers. Hence it is possible for safety managers to interact with site workers if the situation arises. Similarly, Irizarry, Gheisari and Walker (2012) also discussed some of the benefits of using drones for the construction jobsite safety management.

The UAV, equipped with an on-board camera, was flying low (i.e. at an altitude of 500 ft) and an air speed of 30 mph while transmitting
  • 39. 39 the video images and providing aerial surveillance. He concluded that the UAS could eventually be airborne most of the time since the operator would be on duty for any emergency calls. Photograph 2 Drone used for Traffic surveillance Source; aero-vision.com 4.1.3 UAV’s Used for Monitoring Structures (Irizarry & Johnson, 2014), Inspecting and monitoring linear infrastructures such as roads, pipelines, aqueducts, rivers, and canals are very important in ensuring the reliability and life expectancy of these structures. A UAV can stay or fly on top of the structures and transmit a precise image or video stream for inspecting and monitoring purposes. A study, sponsored by the Office of Naval Research's (ONR) Autonomous Intelligent Network and Systems (AINS) program, aimed to develop a control technology that can be used to produce infrastructure monitoring or inspection video using an autonomous UAV. While most UAVs are commanded to fly along a path defined by a sequence of GPS points (called waypoints), this study tried to improve the performance by putting an imaging sensor to detect the linear structure. Therefore, the UAV with a camera can navigate based on visual information rather than GPS information. 4.1.4 Aerial Assessment of Road Surface Condition The assessment of road surface distress is an essential part of a road management system for developing repair and maintenance strategies to ensure a good and an effective road network(Irizarry & Johnson, 2014). Over the last decades, significant progress has been made and new approaches have been proposed for efficient collection of pavement condition data. An innovative UAV-based digital imaging system for aerial assessment of surface condition data over rural roads has also been developed. The system for unpaved road image acquisition consists of a
  • 40. 40 UAV helicopter equipped with a digital camera, a GPS receiver, a ground control station, an Inertial Navigation System (INS), and a geomagnetic sensor. The UAV features an electric engine with a payload of 15 lbs (6.8 kg) and is capable of flying around 25 minutes with a fully charged battery. It can reach 650 ft (approx. 200 m) above the ground and travel at a maximum speed of 30 ft (approx. 10 m) per second. Photograph 3 Drone used for road surface inspection Source; www.aeryon.com 4.1.5 Bridge Inspection Field engineers and technicians working in infrastructure construction or inspection projects need to conduct regularly scheduled routine inspections of highway bridges in order to determine the physical and functional condition of a bridge and to identify changes compared to previous inspections(Irizarry & Johnson, 2014). Furthermore, these inspections are conducted to ensure that a bridge continues to satisfy all applicable serviceability requirements. In LCPC-Paris have started a project pertaining to civil applications of a UAV for bridge inspection and traffic surveillance. A UAV capable of quasi-stationary flights was used to inspect the bridge and detect the location of defects and cracks. The UAV was equipped with a camera, an image transmitter, and a vision system that included INS and GPS. It followed a predefined path and was controlled by visual surveying (vision-based robot control). The size and location of defects and cracks were detected through image treatment. In order to keep the object in the camera's view field, the research team presented a control strategy for the autonomous flight with orientation limits.

This is done using a technique called photogrammetry, which is the science of making measurements from photographs. Urban regional authority of Australia and local drone start-up Avetics have worked on a trial to create a 3D digital model of the Baba House at Neil Road. Creating fine-grained 3D digital models of our built heritage potentially offers a new dimension to document our conserved buildings in more intricate and accurate detail. Planners can use these digital models to plan and carry out research, guide restoration, as well as monitor and manage the state of our built heritage in a more effective way. At the same time, it enables our conservation planners to easily ‘see’ rooftops and other aspects of conserved buildings, such as architectural motifs, without having to physically scale the buildings. Sharing these 3D digital models with the public also enables them to have a deeper appreciation of our built heritage.

Pipeline networks are made up of legs of different lengths, up to thousands of kilometers, and can have above- or below-ground configurations. The safety and security of all pipelines, regardless of their size, placement, or location, is of paramount importance to stakeholders and to the public. Proper maintenance of pipeline networks is also important for environmental protection. Equipment failure such as breakage or leaks can occur for many reasons, including overage of structures and material failure, natural ground movement, accidental hot-tap, and third-party interference. (Gomez & Green, 2014) Large amounts of oil and gas can be lost following a pipe failure, and more importantly, hydrocarbon leaks can damage the environment through contamination and pollution, seriously affecting ecological health and human security. Developing and implementing monitoring systems that can continuously assess the state and condition of oil and gas pipelines is essential.
  • 43. 43 Traditionally, monitoring pipeline networks has often been restricted to visual inspections or volume and mass balance measurements. Currently, most of the monitoring is still performed using conventional methods, mainly through periodic inspections by foot patrols and aerial surveillance using light aircraft or helicopters. Although ensuring a high level of security, the cost of monitoring methods where there is intensive human involvement in the measurements is also very high. Furthermore, the main disadvantage of the methods used for monitoring and inspection is the potential for late detection of failures, when the output (oil or gas) has been reduced, or the environment has already been affected and damaged. Some alternative approaches to monitoring pipelines that do not over rely on human intervention, is the use of UAVs. These can over large and remote areas in a very short and effective period. They are periodically sent out to inspect the oil and gas pipelines in order to detect any cracks, breakages and leakages.

Due to the good flexibility, high efficiency, low cost and damage, low risk, and excellent monitoring ability and widespread coverage, the UAV is capable of the waterborne supervision.
  • 44. 44 Nowadays, the Tianjin Maritime Safety Administration, Guangdong Maritime Safety Administration and Changjiang Maritime Safety Administration have taken a trail and commerce project on the UAV used for the maritime supervision and monitoring of aerial cruise. At the same time, the UAV has been put into monitoring the oil leakage at sea. A series of instances shows that the maritime system, fitted with UAVs and some monitoring systems, Photograph 10 and 11 Drones used for marine inspection Source; www.deltadrone.fr 4.1.9 Aerial Surveying (UAV photogrammetry) The new terminology UAV photogrammetry describes a photogrammetric measurement platform, which operates remotely controlled, semi autonomously, or autonomously, without a pilot sitting in the vehicle. The platform is equipped with a photogrammetric measurement system, including, but not limited to a small or medium size still-video or video camera, thermal or infrared camera systems, airborne LiDAR system, or a combination thereof. Current standard UAVs allow the registration and tracking of the position and orientation of the implemented sensors in a local or global coordinate system. Hence, UAV photogrammetry can be understood as a new photogrammetric measurement tool. UAV photogrammetry opens various new applications in the close range domain, combining aerial and terrestrial photogrammetry, but also introduces new (near-) real time application and low-cost alternatives to the classical manned aerial photogrammetry.
  • 45. 45 Existing UAVs can be used in large-scale and small-scale applications. The system price may vary within some orders of magnitude, depending on the complexity of the system. With costs between €1000 up to several millions of Euro, the system can be similar or even higher priced compared to a standard manned aircraft system. Photograph 12 and 13 Aerial image captured by a drone Source; www.deltadrone.fr From the research who carried out there were 36 respondents interviewed about their knowledge of drone technology. These were mainly from the professional fields electrical engineering, civil engineering, quantity surveying, architecture and project management. 80% of the respondents were electrical engineers. This is due to the fact that the other professionals felt they could not give detail in sight in the use of drone technology. The other reason was most the construction companies interviewed would direct you to the Mechanical and Electrical department that was mainly composed of electrical engineers. This is illustrated from the graph below.

  • 48. 48 According to the research carried out the average number of drones used for a particular activity is 2 drones. This is because most of the work load the companies had did not require the use of more than 3 drones. The figure above illustrates that 60% of the companies that have ever used drones in their activities preferred hiring them rather than fully purchasing and owning the drones. This is because it’s difficult to own one as few companies sell them first of all. Secondly the costs of maintenance, repairs and having a few time drone operators are transferred to the hiring company. The burden of looking for extra work is also placed onto the hiring company. Most of the companies interviewed had were using drone technology in a testing a phase and therefore did not want to commit a lot of funds towards purchasing the drones s From the research carried out it was determined that drone technology had been carried out mostly on road design and construction projects with a few drone work carried out on buildings and pipeline works.

From the research carried out it was found that 60% of companies have used drone technology before, have used drones in average of 2 construction projects underlining the fact the drone is a new technology that has not been fully engraved in the construction industry. From the research carried out it was determined drone technology is mainly used for aerial photogrammetry. This is because drone technology has made this activity far much cheaper, faster and produced more resolute and clear aerial images as compared to the traditional use of a manned aircrafts. Traffic surveillance and marine inspections are activities not often carried out in Uganda that is why no drones have been used in their execution. Using drones for inspection of buildings is still low in Uganda because the types of high resolution cameras that are used for building inspection are still very expensive. There is also high difficulty in maneuvering a drone around a building structure for inspection(Irizarry et al., 2012). 80% companies interviewed did not employ any drone specialist. This is because most of the companies do not use drone technology a lot therefore did not find economically viable employ them.

  • 53. 53 4.3 Rules and regulations surrounding drone technology all over the world Regulations With the rapid development of UAV applications worldwide, coupled with a fair number of ongoing incidents and accidents concerning UAVs and other airborne platforms usually highlighted by the media, there is a growing call worldwide for tightening-up the current rules and regulations concerning who, what, where and when UAV platforms can actually be flown. Already in many countries (e.g. the UK, USA, Australia and Canada) there are moves to regulate UAV flights, and to necessitate education and training of operators and pilots, including best practice, guidelines, and operator insurance amongst many other things. Whilst the UK and USA have been relatively slow in addressing this rapid growth in platform and user-base, Canada is frequently cited as moving in the right direction concerning the rapid proliferation of a wide range of UAV technology, from the hobbyist to the commercial service provider(Juty & Morris, 2015). In 2007, a group of national authorities under the leadership of The Netherlands joined in an effort to develop harmonized operational and technical regulations for “light” (i.e. less than 150 kg) UAS. JARUS (Joint Authorities for Rulemaking on Unmanned Systems) is open to participation from all civil aviation authorities and current participants are from European and non-European countries. JARUS is organized in seven working groups focusing on diverse guidance and regulatory aspects (e.g. detect and avoid technology, command control and communication). The primary output will be recommended operational requirements and certification specifications. For example, the group dealing with technical requirements of platforms is focusing on establishing certification specifications for various types of aircraft, starting with light unmanned rotorcrafts. Expansion of UAVs and applications will have an impact on the airspace, but other industry areas will also be affected and need regulations and adaptation. UAV communication with the ground control system (GCS) requires radio frequencies with sufficient band width. The International Telecommunication Union (ITU) has not yet allocated such bandwidth to UAVs, hence they may have to use different radio frequencies in every country (Everaerts, 2008), something to be considered by international operators and manufacturers.
  • 54. 54 4.4 EU Regulations The capacity and responsibility to regulate UAVs rely on different bodies internationally. In Europe the European Aviation Safety Agency (EASA) regulates all aspects in relation to UAV that have a Maximum Take Off Mass (MTOM) of over 150 kg, while national Civil Aviation Authorities (CAA) deal with light systems less than 150 kg (including fuel) which should fly at altitudes below 150 m. Legal operations with UAVs in Europe currently require:  The RPAS (RPA and remote pilot station) to be certificated or approved by the National Aviation Authority (NAA) of the country where the operation takes place, or certificated or approved by a Regional Authority (RA) with delegated authority. This certification should cover all system constituents necessary for command and control (e.g. transceivers) installed on board the RPA/UAV or on the ground, and under direct management of the Operator.  The Command & Control link to be provided by a Communications Service Provider (COM SP) has to be certificated or approved by the NAA or a RA of the country where the operation takes place;  The Remote Pilot (RP) has to be licensed by the NAA of the country where the operation takes place.  The Operator has to be certificated, approved, or authorized by the NAA of the country where the operation takes place, and is required to possess the obligatory third party liability insurance (which may vary in function of the type of operation). For a specific aerial operation, approved operators have to apply for a flight authorization using a specific RPAS in a defined area, possibly on specific day(s). The duration of the validity of the flight authorizations varies from one day to two years in different EU countries. The International Civil Aviation Organization (ICAO) aims to provide fundamental international regulatory framework through standards and recommended practices with supporting Procedures for Air Navigation Services (PANS) and guidance material, to underpin routine operation of UAS throughout the world in a safe, harmonized in a seamless manner comparable to that of manned operations. According to ICAO, only Remotely Piloted Aircraft (RPA) will be able to integrate into the international civil aviation system in the foreseeable future.
  • 55. 55 RPA that utilize visual line of sight (VLOS) as the basis for navigation would not require an on- board means for determining position or the ability to fly an instrument approach. Operations of these aircraft are usually conducted under visual meteorological conditions (VMC) to ensure the remote pilot can maintain continuous and direct visual observation of the RPA and its surrounding environment. In cases where small RPA have a requirement to fly beyond VLOS, they will need a means to meet navigation capabilities for the airspace within which they are operating. This could involve an alternative means of achieving the navigation performance. RPA that traverse several airspace volumes may operate for the most part under Instrument Flight Rules) (IFR). Such RPA will have to meet the communications, navigation, and surveillance requirements and have an appropriate aircraft operational certification associated with the airspace. 4.5 UK Regulations The Civil Aviation Authority (CAA) in the UK has regulated UAS flights in two documents which are eventually updated to incorporate relevant changes: CAP393 Air Navigation: The Order and the Regulations (CAA, 2014), and CAP 722 Unmanned Aircraft System Operations in UK Airspace (CAA, 2012). Small Unmanned Aircraft (lightweight UAVs of less than 20kg) are exempted from the majority of the UK Air Navigation Order (CAP393 document). However, detailed regulation is established specifically for these vehicles in articles 166 and 167 of the CAP393. UAV that weigh more than 20kg are currently banned from flying in civilian airspace other than in a large zone in west Wales and a smaller one over the military base at Boscombe Down. UAVs that are less than 20kg (small unmanned aircraft) can fly in normal airspace for private use as long as the operator is not planning to use data or images from the flight acquired by flying close to people or objects. UAVs have to remain 150m from congested events or large assemblies, 50m from a person or building, and within visual line of sight (VLOS) (500m horizontally and 122m vertically). Flights beyond VLOS can be permitted but the operators need to demonstrate they can fly the plane safely. Live-streaming from the UAV to the pilot is not considered a good enough measure by the CAA to allow drones to be flown beyond VLOS. Anyone who is using a drone under 20kg for commercial purposes has to be licensed to ensure that they are sufficiently trained to fly the plane and have the appropriate insurance in place.
  • 56. 56 General guidelines to fly UAV for civilian applications in UK:  Small UAV under 7kg can be flown exempt from any restrictive rules  UAV under 20kg can be flown following CAA rules  Fly inside visual line of sight (VLOS): a) Vertically < 400ft (~122m) b) Horizontally < 500m  Maintain a pilot in control, (ability to take manual control and fly the aircraft out of danger)  Stay away from built-up or congested areas  A permission from the CAA is required to: a) fly for commercial use industry b) fly near congested areas Currently, as of December 2014, with the rapidly growing interest in and expanding end-user community, there is increasingly growing concern about the use of UAVs of any size in general. Daily reports of accidents and near misses between drones and civilian aircraft has escalated concern about the safety issues of these small aerial platforms, not so much for commercial operators, but the growing number of individuals and hobbyists who clearly have no sense of the danger and risk that carelessly flown UAV platforms, no matter how small can pose to people, animals, installations, and now passenger airliners, aside from the security and privacy issues that have been raised. Irrespective of whether or not these platforms are classed as toys or aircraft, all platforms with or without sensors on board can pose considerable risk which ultimately will probably lead to a requirement for not only extended guidelines for their safe and responsible operation, but also training, retraining, and insurance. 4.6 UAVs and privacy The potential uses for UAVs stagger the imagination. The units are relatively inexpensive, so the possible pool of users is much larger than for conventional aircraft or helicopters that historically have been used for aerial monitoring or photography. Drones can go many places a plane or helicopter cannot, such as over fences and next to windows, and that ability raises serious privacy issues. Intentions might not even be an issue: an agent using a UAV to take a panoramic video of a listed property might find that he or she accidentally recorded a view of the neighbors inside their home.
  • 57. 57 In 2013 and 2014, 15 states in the USA enacted laws relating to UAVs and privacy. Of these, most initially focus on law enforcement drones. Eleven states (Alaska, Florida, Idaho, Illinois, Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah, and Wisconsin) passed laws that specifically require law enforcement to obtain a warrant before conducting a search with a UAV. In Iowa, the state law also prohibits the use of UAVs to enforce traffic laws. States also moved to protect individual privacy from private drones. Laws in Indiana and Louisiana make it a criminal offense to use a UAV to monitor or photograph property without the property owner’s consent. In Illinois and Tennessee, it is unlawful to use UAVs to interfere with hunters and fishers. Idaho law allows a person to bring a lawsuit against one who uses a UAV to photograph or record the person without his or her written consent, if the operator intends to publish or publicly disseminate the photo or recording(Planners, 2015). North Carolina also grants a private right of action to a person who is photographed without their consent by a drone operator. In Oregon, the law allows an owner or occupant of property to bring a civil action against a person who flies a UAV over the property at an altitude of less than 400 feet in certain circumstances. 4.7 Rules and regulations surrounding drone technology in Uganda In Uganda at all aircraft machinery operating in Ugandan air space are subject to regulation by the civil aviation authority of Uganda as stipulated by civil aviation authority act 1991 that states that all aircraft operating in Uganda airspace, whether the aircraft is of foreign or Uganda registry, and to Uganda aircraft operating outside of Uganda territory shall be subject to this act. With that said, since drones are considered to aircraft that means drone activities in Uganda are bound by this act. Therefore, a person with the intention of flying a drone should be in line with this act. However, since drone technology is a new and emerging market in Uganda civil aviation authority has not set up any regulations as of the time this research was carried out. This is because civil aviation authority of Uganda subscribes to the international civil aviation authority organization Chicago convention and as of the time this research was carried out plans for proper integration of drones into the airspace was still in its infant stages.However, the international civil aviation authority organization has set time lines for for integrating all drone classes: By 2018, initial integration into non-segregated airspace (i.e. where manned aircraft also flies). By 2028, full integration, i.e. so that drones can communicate with air traffic control
  • 58. 58 Procedure carried out before operating a drone in Uganda  Every drone project should lay in a certain ministry. Therefore, permission for one to use a drone is first sought from that ministry. For example, if a student wanted to fly a drone, then he would seek for permission from Ministry of education and Sports.  Then he would have to go to the highest security organ in the land which is the central military Intelligence(CMI) at the headquarters of Ministry of Defense. He is then awarded a letter that makes the security organ aware of his activities.  He then proceeds to apply to fly the drone in Ugandan air space from the civil Aviation authority.  If accepted, he then proceeds to the area of interest and then seeks permission and letters of acceptance from the local authorities like the police station or barracks in the area, the LC5, LC3 and LC1 of the area. Information to be availed to the various authorities  Type and purpose of work to be done  Duration of work  Area of coverage of work  Type of drone and equipment specifications to be used  Information to be collected
  • 59. 59 5.0 CONCLUSION AND RECOMMENDATION Introduction The main objective of this research was to assess the applicability of drone technology in Uganda’s construction industry. This chapter includes the conclusions, contributions and recommendations that can bring forth drone technology to the construction industry. This research had 5 specific objectives which were achieved through reviewing literature and data collection using interview guides and participant questionnaires. The data collected was then analyzed in detail. The first objective was to identify the activities drones can perform in the construction industry, the second objective was to assess the economic impact drone technology would have on the construction process, the third objective was to identify the rules and regulations surrounding the use of drone technology in Uganda, the fourth was to identify the challenges facing applicability drone technology in Uganda and the last was to suggest remedies and recommendations. Conclusions  It is an established fact that most construction professionals do not know about drone technology being used in the construction industry.  There are no proper and clear rules, regulations and registration procedures surrounding the use of drone technology in Uganda.  Most construction companies that have used drones in the construction process just hire them for a particular task.  Drone technology is mainly used in when inspecting and monitoring infrastructure  There is limited skilled man power that can properly operate and process data from drone technology.  There is also limited access to spare parts and repairs for drone technology in Uganda. The construction industry plays an important role in the economic contribution for the development of the country. Therefore, incorporating drone technology would surely make construction industry faster, easier and more accurate in order to carter for the ever increasing demands laid upon it. Despite the increase awareness and use of drones in other sectors, the government and professional bodies in the construction industry should come with more mechanism to promote the use of drone technology in the industry.
