PAS 128 & Utility Mapping

We provide clients nationwide with a wide range of different survey solutions, including PAS 128 which is used to detect abandoned or redundant utilities below ground.

Different surface features can also be detected and this service benefits the location and classification of underground utility infrastructures. With a PAS 128 survey you are guaranteed a subsurface engineering industry standard that sets the accuracy and quality of captured data. This gives our team and our clients confidence, knowing that all data is precise.

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. Our professional surveying team carries out utility mapping on sites prior to any construction works commencing, including borehole and trial pit works. When a survey conforms to PAS 128 it can indicate underground utilities before breaking ground.
