PAS 128:2014 Specification for underground utility detection, verification and location

PAS 128:2014

Specification for underground utility detection, verification and location

Status : Current   Published : June 2014



What is this PAS about?

 It provides a way to accurately map underground utility networks. 

Who is this PAS for?

  • Practitioners (surveyors, geophysicists, subsurface utility engineers)
  • Clients (engineers, constructors, project managers)
  • Utility owners

Why should you use this PAS? 

Sponsored by the Institute of Civil Engineers, it specifies requirements for the detection, verification and location of existing and new underground utilities.

It applies to active, abandoned, redundant or unknown underground utilities and the location of their associated surface features.

It applies regardless of where these utilities are located (e.g. in urban or rural areas, in the street, on private sites, such as hospitals or airfields). It applies to utilities buried no deeper than three metres.

It sets out the accuracy to which the data are captured, the quality expected of those data and a means by which to assess and indicate the confidence that can be placed in those data.

Specifically it covers:

  1. Project planning and scoping process
  2. Classification system for quality levels based on survey category type, location accuracy, inclusion of post-processing and level of supporting data
  3. Desktop utility records search
  4. Detection 
  5. Verification
  6. Location
  7. Deliverables

The benefits of the PAS are:

  • It enables those involved to make informed decisions using more complete, up-to-date and accurate data. This reduces conflicts, delays, utility service disruptions, redesigns, personal injuries and even loss of life
  • Accurate utility data could also lead to as yet unrealized benefits, such as the use of remote robotic techniques to maintain asset networks in busy highways in future, reducing the need for intrusive road excavations
  • Accurate mapping of utility networks could improve asset modelling capabilities
