johannesburg Utility detection & gpr survey services

Underground utility detection is done by locating and mapping underground utilities, as the name implies. The location and depth of underground pipes, cables, and inspection pits, as well as cambers associated with power, communications, water, storm-water drainage, sewerage, gas and signaling utilities, are among the types of data collected.

At Freelance Geomatics ZA, we use a variety of techniques to detect underground services. Some of the techniques we use include; electromagnetic, geophysical and high frequency induction. These techniques allow us to detect, map and validate positions of underground services and utilities.

Lifting all pit covers and manholes is part of the mapping process in order to gather and detailed data on pipe and chamber sizes, flow direction, construction materials and utility type. All of these details are then documented by a Surveyor, through high accuracy total station and GNSS survey techniques. The final data output generally includes 3D spatial maps, showing depth and position of the utilities.

There are many advantages of utility detection and mapping, however the following are its main advantages:

• Utility information is essential for project planning and feasibility analysis

• Techniques used to detect utilities are non-invasive, they require no digging and do not disturb the ground.

• Utility information helps the contractor know the positions and depth of underground assets, this information enables the contractor to avoid digging through buried utilities. Damage to buried utilities can result to unexpected project costs, services disruption, disaster and project delays.
