Survey Control Networks

Survey Control Networks

Construction site control networks are a series of survey stations. These can be used as reference for setting out of grid lines, benchmarks, walls and any building elements.

These can be primary and secondary. Location and accuracy of control points is crucial for the whole construction process.

Our construction teams have years of experience in establishing surveying and postprocessing of any control network. Control networks can vary depending on type on construction site and accuracy we want to achieve. We have a good experience in all types of control networks, we do linear control networks for infrastructure, precise control networks (precise levelling, precise horizontal measurements) for structural monitoring and control networks for civil engineering. To establish a proper control network we work with the newest and most precise equipment. Our team will ensure that the network is established correctly with required accuracy and in line with your needs.

Maps and plans are produced to scale, designed to show the details of the environment accurately. Accuracy is vital as these plans may be used to calculate flood risks, resolve boundary disputes, and many other uses.

Topographical surveys are commonly used for planning the construction of roads, railways, pipelines, etc. and can help inform the placement of buildings within a construction area.

Topo maps are created by a topographer taking measurements of the land, including all physical features, and producing a map to the specification required. Contour lines showing changes in ground elevations concerning distance or direction will be included.

We provide services for vast range of construction sites:

Power Substations and lines



Residential Developments

... and more


At Geo Cart, we provide a comprehensive range of engineering surveys for construction, renovation, and repair projects. Geo Cart’s engineers are experts in engineering surveying, and mapping.

To ensure accuracy, the staff at Geo Cart are trained in various areas, including GPS, TotalStation, Laser Scanning, GPR Underground Surveys, surveying techniques, and drafting software application skillsets which allow them to generate topographic and underground utility maps. This enables our engineering surveys to be highly accurate, which is critical for successful projects.

Although these surveys can be time-consuming, it’s essential to do them right the first time so that you don’t have to return later and spend money on additional engineering surveys. Understanding the area you are working in ensures the safety of your team and minimizes the problems you will face during the project.

You need to know if your work will interfere with any water or sewage pipes buried in the area, as well as identifying the location of any electrical cables or gas lines that may have been installed there since the last engineering survey was done.

We provide the engineering surveys your project needs.

We are authorized to make projects on power substations, power lines and other types of buildings.
