Topographical Surveying

Topographical Surveys

a key starting point for any project whether it be residential, commercial or rural

Our topographical surveys visualise the features and contours of your land before you get to work. We’ll provide you with ample information including all existing features and levels of the property, boundaries and even drainage where possible to assist with every aspect of the design stage.

In essence, we will provide you with a PDF plan as well as a 3-dimensional DWG file of the property showing all natural and man-made features and improvements. Specific information, such as location, size, height, and any changes in elevation will be surveyed and visible on the Plan and DWG file.

What do we survey?

Features are identified when a topographic survey is completed. Most features surveyed are standard, but additional features can be requested from the client (private owners, architects and/or engineers). These include:

When do you need a topographic survey

Topographic surveys may be required as part of a civil engineering and architectural design and construction projects, including:

Using data from Topographic surveys

A GPS (Global Positioning System) or Total Station is used to record the measurements of a topographical survey. Each point will have a coordinate defining a certain feature on the site. The information of a topographic survey is presented as contours, lines, and symbols on a site plan. 

A drone can also be used for aerial mapping especially on larger projects. The drone will take images of the site which can be converted to a 3D rich point cloud and/or surface for a detailed survey. 

Once all the information is obtained after conducting a topographical survey, we can produce high-quality drawings, plans, 3D point clouds for 3D models, photographs, and attributes such as chamber inverts and pipe diameters. 

Most importantly a topographic survey can help prevent any expensive issues or mistakes that can occur down the line because you will have full detail of the specific site.

Using data from Topographic surveys

A wide range of information is provided after a site has been surveyed. The information can be used to produce detailed drawings. The survey results can be used for:

Frequently Asked Questions

To read a topographic survey, one needs to look at the contour lines. The contour lines detail where the terrain meets a specific elevation value on any given site. These can be interpreted to show where there are depressions and rises in the ground.
Topographic surveys form the basis for any development on a site. It is conducted to identify and map terrain features of a land area that exists above and below the ground, for example, buildings, services, roads, manholes, walkways, retaining walls, utility poles and vegetation. These surveys include boundary lines and easements.

Topographic surveys are carried out when an area is being assessed for new construction or the addition to new development.
It depends on the location of the site, the size of the site and the amount of detail required.
