What is PAS 128 (Underground utility detection) ?
PAS 128 specifies requirements for the detection, verification and location of active, abandoned, redundant or unknown underground utilities and the location of their associated surface features, irrespective of location.
Also known as Utility Surveys or GPR Surveys, these surveys are essential in, detection, positioning and identification of buried pipes and cables beneath the ground. Our utility surveys combine the techniques of manhole lifting, Radio Frequency/Electromagnetic Location (EML) and Ground Penetrating Radar (GPR); we can easily detect and map metal pipes, plastic pipes, electricity cables, drainage systems, telecoms, traffic signalling, and fibre optic cables.
For detecting metallic and non-metallic services, full utility detection and mapping, past site occupancy surveys, single service tracking, buried tank or reservoir location.
The Benefits of PAS 128 (underground utility detection)
- Eliminating the risk of a strike
- All of the final delivery are in the same standards
- The safety of the workforce and public
- Minimise utility damage
- Minimise project delays
- Saving costs producing as built records
- Designing and planning, knowing the constraints –
- Safety in Design
- True 3-Dimensional data
- Optimal resolution at all depths
- Pavement – Delamination. Dowel Bar Alignment. Rebar
- Bridge Decks – Rebar health. Overlay. Delamination
- Voids – Sinkholes
- Utility mapping – Power cables. Pipes
