Utility Detection Surveys
Using Electromagnetic Location (EML) and Ground Penetrating Radar (GPR) equipment we are able to accurately locate sub-surface utilities. This can either be 2D or 3D data superimposed onto survey base data, either client-supplied or produced in-house.
All our underground services surveys adhere to PAS128, the industry recognised specification for underground utility detection, verification, and location.
Accurate location of subsurface utilities
Using Industry-recognised methods of Electromagnetic Location (EML) and Ground Penetrating Radar (GPR), we can precisely locate underground utilities during an underground utility survey. Our state-of-the-art technology allows us to generate accurate 2D or 3D data, which can be superimposed onto a measured survey base for a comprehensive understanding of the subsurface infrastructure. In commissioning a utilities detection survey you can ensure that excavation and construction projects are conducted with maximum safety and efficiency, minimising the risks associated with accidental utility damage.
PAS128 is the benchmark for underground surveys, and at Laser Surveys all our underground surveys are compliant.
This means that all our surveys benefit from the best practices outlined in PAS128. This means we apply the same high standards in data collection, interpretation, and reporting, ensuring a reliable and detailed understanding of underground utilities, regardless of survey type.

PAS128-Compliant Underground Surveys

All our underground services surveys adhere to PAS128, the industry recognised specification for underground utility detection, verification, and location. PAS128 ensures a consistent, high-quality approach to surveying buried services, minimising risks and enhancing the reliability of data used for construction, design, and infrastructure projects.
What is PAS128?
PAS128, developed by the British Standards Institution (BSI), sets out a structured methodology for underground utility surveys. It defines survey types, quality levels, and data capture techniques, ensuring that utility information is as accurate and reliable as possible. By following PAS128, our surveys deliver a clear and comprehensive understanding of underground assets, reducing uncertainties in project planning and execution.

Testimonials
“I felt I needed to write you an email regarding your two operatives, Dan Jenkins and James Green. They worked incredibly well today and have found exactly what we needed to know. They also managed to help out in discovering another manhole, which I’m glad they’ve brought to our attention.
I would be very happy to use Laser Surveys again given the current performance of your two operatives and if there is anymore work on this site I would request the same two people to do the work”
