PAS128 Compliant Utility Surveys

What is PAS128?


PAS128:2014 is a British Standards Institution (BSI) document specifying requirements for the detection, verification and location of existing and new underground utilities. PAS128:2014 was sponsored by the Institution of Civil Engineers (ICE) in conjunction with the BSI. PAS128 provides a transparent and robust methodology for delivering utility surveys in the UK.

PAS128:2014 defines four Survey Category Types ranging from D to A, representing increasing amounts of accuracy. You can specify the desired level of accuracy when requesting a PAS128:2014 compliant survey.

Macleod Simmonds performs Utility Surveys to the highest level of accuracy as defined by PAS128:2014. By providing the best possible survey results, we help you to make timely, informed decisions, designing out potential issues before they become problems. Our interpretation of the PAS128:2014 M4p level survey exceeds the specification in many aspects, whilst remaining competitively priced.



Our PAS128:2014 compliant surveys help you to precisely specify the type of survey you need, whilst understanding the methods and techniques that will be deployed at each accuracy level. This increases confidence within your project team that they are using accurate information before breaking ground.

Specifying a PAS128:2014 survey means that the data must be gathered strictly according to the BSI survey methodology. This ensures that all data are of a reliable quality.
