-Methods of locating contour:
A- The direct methods
1- Level and staff method.
2- Plan table and alidade method.
Direct method procedure:
In this method the actual contour is pegged out on the ground and its
planimetric position located. A back-sight is taken to an appropriate BM and
the HPC of the instrument is obtained, say( 34.800m.) A staff reading of
0.800m would then place the foot of the staff at the( 34m )contour level. The
staff is then moved throughout the terrain area, with its position pegged at
every 0.800m reading. In this way the 34m contour is located. Similarly a
staff reading of (1.800m) gives the 33m contour and so on. The planimetric position of the contour needs to be located using an appropriate survey technique.

Test holes are commonly used to determine the “true” elevation of an existing underground utility. We can achieve this information with vacuum excavation, which is the highest quality level in the S.U. E process. Vacuum Excavation is a process where high pressure air or water is shot into the ground to loosen the material ( dirt, gravel, clay, etc.) around a utility line. The loose material is then vacuumed out, hence exposing the desired utility. We now can gather all the necessary information needed to identify the utility and it’s elevation.

Ground Penetrating Radar, also known as GPR, is a tool that is used to find Underground Utilities, Underground Storage Tanks (USTs), and in some cases, Graves. The depth and accuracy are dependent on a number of variables, such as soil density, moisture content, and antenna frequency. We use a 350 MHz antenna, which has the potential to reach depths of up to 35 ft (in perfect situations).

The importance of underground utility detection and mapping
1.
2. If you are building or constructing a new house or office, then you
must get underground utility detection. It gives you a rough idea on
how easy or difficult it is to do a particular project in that area.
3. With the most advanced tech used in it, it shows the colour coded mapping
of that area. This reduces the burden of huge excavations and does your
work in a very simpler manner.
It is very much advised to install this detector whether it is a big project or
a small project. It is a safe decision.
4. It is important to install this so that you the likelihood of your area. How
feasible or easily constructible your area is. It counts how much utilities
are there and also finds everything about the owner of the land.
This will make sure that you don’t get into any kind of issue or trouble.
5. For instance, if a site designer intends to change a modern unit into
private property, they should check the accessibility of adequate utilities
required for taking care of the demands of society.
This additionally implies checking underground to detect any potential
risk covered underneath that needs to be expelled before the
development starts.
6. Dangers incorporate waste from past site, any dangerous gas pipeline, and
so on that needs quick work. With the assistance of an underground utility
recognition specialist organisation will have the capacity to answer every
one of these inquiries.
They utilize the most recent innovations like ground entering radar and
radiolocation methods to help the site designer spare both time and cash.
7. All the information that is provided by this detector is very useful for the
builder, and it is priceless for him.
It can also locate telephone portals or inspection chambers.
8. You can clearly tell how important is us for a builder to have a detector. If
there is a nuclear waste beneath the land and is not detected the first hand,
it can cause a huge problem.
The radiation can affect the land as well as the individuals working there.
9. There is also an over ground utility detector which tells about all
the stuff you need to know about for the surface of the land. A
builder is advised to have both so that he can be safe from all the
possible dangers. Now let’s move to the importance of the
detector!
11. · Rectifying Mapping Errors
As significant as utility endeavours to be, human blunders are conceivable.
A slight blunder in a flag can prompt employees coincidentally serving a
fibre optic line, harming a gas fundamental, or reducing power to the area.
Ground-infiltrating radar enables employees to see under the surface,
reducing or diminishing vulnerability without the time or cost of digging.
12. · Recognizing Potential Threats
Not all utilities or underground dangers in every case are accurately
mapped.
For example, if the property where your house will be built was at one
time a modern site, it might contain unused gas lines, underground fuel
tanks, or different impediments which could be perilous whenever
found amid the development procedure.
13. · Finding Existing Resources
Before a designer starts building private properties, they might need
to affirm that the utilities that owners require already exist.
With ground-infiltrating radar, an expert can find electrical cables, and
different utilities that were there starts uncovering, giving the worker
a chance to adjust their plans, sparing the cost of changing plans later.
14. · Making Working Environment Safer
Engineers can easily adjust the layout plan for construction once
the underground map is updated and accurate.
The underground mapping is an inevitable reference to work
around obstructions, even before the planning.
15. As a result, it not only creates a safer working environment for
everyone but also offers protection from fatal accidents for the crew.
For instance, if labour accidentally comes in contact with the main
power line, it may result in severe injuries and even fatalities.
16. Even the pressure of the water pipe can propel the water and debris to
workers.
However, such kind of unfortunate events is easily preventable with the
help of an underground utility mapping.
17. · Having a permanent record
There is a need to keep the permanent records of the surveyed site as a
part of an underground project. This may be the case as well if a project
is just under the developmental stage.
So, in case if a client needs to re-visit the design, already having the
important information and data in records comes in handy.
18. But, how do the results of underground mapping look like? With the
help of pioneering ground penetrating radar, it becomes easier to see a
clear picture of what’s lying around.
It can be plastic pipes, electricity cables, drainage systems, telecoms
and fibre optic cables. Even the buried things will show up and can be
added to the map.
19. Underground Utility Detection and mapping.
It is especially necessary for industries to use this, the dangers
involved in the industry is far more than normal constructions.
20. You need skilled personnel to decode and intercept the information.
The work is very difficult and tiring, yet important.
It is recommended to have Underground Utility Detection and
mapping.
