Underground Service Location

STS Ltd. provides cost-effective and accurate service location surveys generally utilising a multi-technique approach to maximise the potential for underground service detection.

The methods utilised will vary depending upon individual site conditions  with equipment such as Radiodetection electromagnetic service location devices, Ground Penetrating Radar, Magnetometer and other electromagnetic systems all providing service location capabilities in certain circumstances. The use of these types of detection techniques, coupled with direct visual survey methods and correlation with existing documentation, provides the most accurate service location solution.

Survey results are generally provided in plan format, with detected service locations superimposed on digital site plans, indicating the nature of the detected service line and depth estimate. However, services may also be marked directly on the ground if required.

Service location surveys range from the location of single pipeline or cable routes to the full scale investigation of complex underground utilities in roadways, chemical plants and fuel filling stations for example.

The proposed refurbishment of a number of blocks of flats in London required the existing services to be accurately located to ensure that any excavations could be carried out safely. A combination of methods including ground penetrating radar, electromagnetic service location devices and visual inspection were used to create service/utility location plans
