Unmanned aerial vehicles can be used for 10 construction applications: 1. Creating promotional and marketing material using aerial and ground images. 2. Routine progress monitoring through monthly or biweekly flights to capture images of development over time. 3. 3D modeling using photogrammetry to create accurate CAD models of structures or terrain from aerial images.

2. Let’s get the basic ones out of the way first shall
we. At the very heart of unmanned aerial
vehicles is the ability to place a sensor – camera
or otherwise - in a three dimensional space with
relative ease.
Aerial and ground based images and video can
be combined to create stunning, high impact
footage.
This not only looks good, it also conveys a lot
of information about the property, its size and
its surroundings.

3. Routine progress monitoring
Throughout a development’s
construction phase (and even before)
agreed flight paths over and around
the site can be made to provide almost
real time visual progress reporting for
developers, stakeholders and even the
people on site as an engaging record
of how the project is going.
We recommend either monthly or
fortnightly visits with a number of ad-
hoc visits throughout the development
to capture key milestones.
Reports are typically created within 48
hours.

4. 3D modelling
Using photogrammetry and GPS ground
control points, accurate 3D models of a
surfaces or structures can be created and
exported as CAD files. These have a
number of design and planning
applications as terrain or structural
models do not have to be created from
measurements or from scratch.
Existing CAD files of a finished structure
can be imported into the terrain model to
provide a simple and effective visual
representation of the finished project for
planning, pitching and consultation.

5. Inspection and survey
Unmanned aerial vehicles are ideal for
gathering data from hard to reach
places. In some cases this may be as a
cost effective alternative to scaffolding
or a cherry picker, though in the case of
heritage sites, drones are a less intrusive
means of inspection and less likely to
incur damage to ground and structures.
Data gathered can then be processed
into an inspection report or using the
geo-tagged images and video imported
into third party software to create long-
term monitoring.

6. Planning and consultation
Pictures say a thousand words. When
consulting with local residents or planning
agencies, being able to convey a proposed
development in the context of its environment
is hugely beneficial.
Up to date and informative visual material can
also be produced to evidence key
commitments to local authorities or planning
agencies such as parks, roads, greenspaces or
tree protection orders.

7. Line of sight visualization
Want to know what the view will look
like from the top floor of your new
development? Drones are a fast and
cost effective means to capture this.
The same principle can be applied for
signaling or communications equipment
when establishing what height a mast
or receiver must be to transmit an
unobstructed signal to another point.

8. Volumetric measurement
Using accurate aerial photogrammetry techniques,
large areas (2D and 3D) can be measured to within
CM accuracy. This can be accomplished quickly,
cost effectively and with minimal disruption to the
day to day workings of the site

9. 360 VR material
Virtual reality devices such as Google
Cardboard are cheap and readily
available. By capturing 360 degree
imagery by drone and viewing the
outputs in such devices provides an
immersive and useful representation of a
site from an elevated point of view.
This is not only effective in understanding
the location of a site in context with its
environment, it is also hosted online
meaning it is easily sharable.

10. Aerial imaging can be used to record how tools, machinery, temporary structures and
assets are stored and maintained in the context of their environment. This can
support health and safety and insurance commitments as well as providing an audit
trail for compliance purposes.

11. Thermal imaging
In recent years, thermal imaging sensors have
become much more compact and feature
state of the art radiometric measuring
capabilities. These units can gather high
resolution (640x480) thermal imaging data at
±2% accuracy.
The benefit of mounting to an aerial platform
is that it can view subjects at angles either
previously unachievable or via a costly and
time consuming cherry picker. Thermal
imaging data can also be gathered quickly
and the outputs viewed live on the ground via
a monitor.
