How to accurately map underground utility networks
What’s happened and why?
The PAS specifying requirements for the detection, verification and location of existing and new underground utilities has been fully revised.
What does PAS 128:2022 cover?
The detection, verification and location of active, abandoned, redundant or unknown underground utilities and the location of their associated surface features, irrespective of location. Specifically it covers:
- Project planning and the scoping process
- The classification system for quality levels based on survey type, location accuracy, inclusion of post-processing and level of supporting data
- Desktop utility records search
Why use PAS 128:2022?
A current utility mapping survey conforming to this PAS can be used as an indicator of the presence or absence of underground utilities before conducting further ground investigation prior to breaking ground.
And if a full detection survey is not available prior to a ground investigation, then this specification can be used to support the detection, location and avoidance of buried services as part of a permit to break ground safe system of work.
In addition the specification’s use can lead to more effective planning and safer execution of works as well as less conflict, delay, unnecessary work, damage to third party assets, utility service disruptions and redesigns.
