Utility Surveys

A utility survey is a specialist investigation used to detect, locate and map underground services within a site. These services may include electricity, gas, water, drainage and telecommunications infrastructure. Utility surveys provide accurate and reliable data on the position and depth of buried assets, supporting safe design, planning and construction activities.

Geospatial delivers utility surveys with a strong focus on technical quality, risk management and compliance. Our surveyors are highly experienced in working across complex sites and constrained environments. We apply industry recognised methodologies and robust quality controls to ensure data accuracy and consistency. By maintaining independence and technical integrity, we provide objective information that clients can rely on at every project stage.

Post‑processing enhances raw GPR survey data using specialist software to improve clarity and interpretation. This allows us to identify buried features that may not produce a strong metallic signal, such as plastic pipes, ducts and voids. As a result, utility detection is more comprehensive, reducing uncertainty and improving confidence in the survey outputs, particularly on complex or congested sites.

Accurate knowledge of underground services is critical to reducing risk during design development and construction works. Utility surveys inform safe excavation strategies, support coordination with other disciplines and help avoid service strikes, programme delays and unplanned costs. Early identification of constraints enables more efficient design solutions and improved site safety outcomes.
