Utility surveys

We provide accurate and fully compliant utility surveys to help you locate and map underground services before excavation or development begins. Our surveys reduce the risk of service strikes, improve planning confidence, and support safe, efficient project delivery.

What is a utility survey?

A utility survey identifies the location, depth and type of underground utilities, such as electric, gas, water, telecoms and drainage infrastructure, using a combination of non-invasive techniques and physical verification. This information is essential for safe design, planning, and construction in built environments or greenfield sites.

Utility surveys are critical for:

  • Reducing health and safety risks
  • Meeting planning and CDM regulations
  • Designing around live services
  • Supporting permit-to-dig and risk assessments
  • Verifying utility locations prior to excavation

Our approach

We use industry-leading techniques, including electromagnetic location (EML), ground penetrating radar (GPR), and vacuum excavation where required, to accurately detect and trace buried assets. Surveys are carried out to PAS 128 standards and tailored to suit your site conditions, project stage and information requirements.

Our service includes:

  • PAS 128 utility surveys
    • ​Type D – Existing Utility Records Search
    • Type C – Site Reconnaissance with visual site inspection
    • Type B – Detection Survey (Non- intrusive with Electromagnetic Locators (EML) & Ground Penetrating Radar (GPR), given a quality level (QL1 -QL4) indicating the confidence in horizonal and vertical accuracy.
    • Type A – Verification (Intrusively expose services for physical check using Trial holes and vaccum Excavation)​
  • Drainage tracing and CCTV integration
  • Utility mapping with topographical overlay​​

We deliver clear combined service models, 2D CAD/3D CAD/GIS drawings, reports, pit schedules and digital outputs to help you plan confidently and work safely.
