The wide range of utility survey solutions we offer to clients around the UK includes PAS128 Surveys which detect abandoned or redundant utilities below ground.
We have the skills and equipment to detect many different surface features, as well as classifying and confirming the location of various underground utility infrastructures.
With our PAS 128 surveys, clients are guaranteed a subsurface engineering industry standard service that sets the accuracy and quality of captured data; you can be confident in the knowledge that all data is precise.

PAS128 -Type D, C, B, A:

The four quality levels within PAS 128 range from ‘A’ to ‘D’; to satisfy the project need and address safety and financial risk, the survey area can be subdivided to ensure the appropriate survey level is applied to each.
Before construction work begins on a site, our professional surveying team carries out utility mapping services such as borehole and trial pit works. When a survey conforms to PAS 128 it can indicate underground utilities before breaking ground.

Subvision Surveys’ clients are guaranteed to receive the highest possible standards of service and for a great price. We use a wide range of state of the art equipment and our skilled team – who have been trained for many years – have the latest specialist techniques at their disposal. Our experience of working on large scale projects includes The Shard, Heathrow Terminal 2 and Wembley.
