A utility survey is a type of subsurface survey that involves identifying all the underground utilities and service routes, including gas, water, telecommunications, electricity, drainage, and voids in a specific area. To conduct a utility survey, two primary methods are used: Ground Penetrating Radar (GPR) and Electro-Magnetic Locators (EML). The GPR method sends signals into the ground and listens for reflections from the signal, while EML detects the electromagnetic signal emitted by power cables. However, it is important to note that GPR should always be used alongside EML techniques for the best results.

Having accurate information about the underground services located on a site is crucial in complying with health and safety regulations, reducing project planning time, and minimising risks. The location of the underground utilities is usually marked on a topographical survey plan, along with above-ground features like buildings and boundaries, to create precise survey drawings for clients.

No matter what project you are considering, it is always recommended to have a thorough and accurate survey drawing to minimise the risk of cable strikes and other mistakes.
