Topographical surveys are necessary
only before starting with construction work, as it helps in doing the work of
surveying land. Carrying out this survey helps in determining and locating
different features present in any land, be it a manmade or another kind of
natural characteristics. Compared to other surveys, this one is different since
it helps in studying and knowing regarding the elevation of the land surface.
The crucial measurements required for doing the survey is mostly taken by
utilizing the GPS and EDM. The map contains parcel elevation which is shown
with the help of contour lines that are highlighted through Earth surface
contours and also with elevations. It depicts the present underground
attributes like the presence of man-made or natural gas lines, fences, utility
poles, retaining walls, wells and more. It provides information that can help
designers to create suitable designs fitted to the specified land.
There are different ways of doing
these surveys such as GIS or Geographic Information System, GPS, LIDAR and
Theodolite surveys.
Who
Utilize These Surveys?
Mostly an engineer requires the
survey since they have to understand about the land surface and its elevation
and find out if it is necessary to do any work or making any adjustments inside
the property. Apart from an engineer, even an architect utilize this survey for
designing a blueprint of any upcoming construction project which assists them
for getting a green signal before starting with the groundbreaking process. In
case any of the building has particular topographical threats and challenges
like steep grade, or any kind of issues then a detailed survey is necessary to
be done before beginning with the construction. This makes sure that the
planned design works accurately in the given condition. Any government agency
before beginning with the construction work or zoning regulations performs the
survey which helps in evaluating the already present infrastructure.
When
Is Survey Required?
Topographical surveys are also commonly known as contour surveys is considered as
a part of the transactions made in real estate, different construction projects
and also for making any of the designs in civil engineering which includes
remodelling of the different projects, designing a new road or any kind of
drainage projects. With the boundary survey, all of these surveys are utilized
by the architects along with engineers for making accurate designs depending on
the present conditions.
Importance
For proper understanding and knowing
about form, shape and also as the geographical position of various land
features. These surveys are essential for designing a farm, garden or any
highway. It targets mainly on gathering essential data of land features along
with its altitude.
Therefore, these are the basic
things that are necessary to know about topographic surveys.
