Underground utilities

Underground utility survey

Understanding the location of buried services can be key to the successful delivery of a design or construction project. An underground utility survey from Premier Surveys provides accurate mapping of below-ground infrastructure, allowing our client to make informed design decisions and facilitate safe project works. Our experienced utility surveyors use a combination of Electromagnetic Location (EML) and Ground Penetrating Radar (GPR) technology to locate buried services and deliver high-quality mapping to a variety of bespoke specifications, including PAS128. In addition to our mapping works, we also undertake service verification surveys where requested.

Desktop utility survey

As part of a compliant PAS128 survey our experienced team can also provide comprehensive ‘Type D’ desktop utility surveys. Sourcing information from a variety of asset owners, we compile the detail into a clear and concise report. This provides our client with an outline understanding of the public utilities to assist with early planning and feasibility considerations. This service is often complimented by a detailed underground utility mapping survey, providing comprehensive underground service knowledge to inform more detailed design considerations.

Borehole clearance survey

Extending from our utility mapping works, we also provide borehole clearance surveys. Using locations proposed by our client, our team can set out the position of proposed boreholes and conduct below-ground surveys to determine any potential clashes with existing services. Where required we will recommend alternative locations for site investigation, negating additional costs for separate setting-out works and providing cost-saving benefits in the process.
