Underground Utility / GPR / PAS128 Surveys

Sub Surface utilities such as electricity, gas mains and other services run beneath our feet without us realising. Existing statutory authority records identifying the position these utilities often do not provide the level of accuracy needed for construction projects and a more detailed utilities survey may be required. With a good utility survey showing below ground services, you vastly reduce the possibility of any utilities strikes and ensure digging and excavation activities are carried out as safely as possible.

PAS128 Specification Standard

Surveys are generally provided to the PAS128 standard as required. Equipment includes Ground Penetrating Radar (GPR) and Electromagnetic Location (EML) tools. We can of course, provide the base mapping (topographic survey) to overlay the services information onto, or, we can use good quality client supplied surveys.
