PAS 128:2014 Survey Standard

Desktop Utility Records Search (Survey Type D)

This survey would be in the form of a report using record information obtained from utility service providers, showing their assets within the survey area identified, usually in a drawing format. This data is presented in drawings and pdf documents.

Site Reconnaissance (Survey Type C)

This survey would accompany a Desktop Search (Type D) and involves a site reconnaissance visit to identify physical features that support the existence of utilities within the survey area, usually in the form of manholes, inspection covers, street furniture and excavation scar lines. This data is presented as a record overlay onto a topographical survey or Ordnance Survey plan.

Detection (Survey Type B)

This survey would accompany a Desktop Search (Type D) and involves the scanning of the site area using at least 2 geophysical survey techniques. A minimum of GRP (Ground Penetrating Radar) and EML (Electro Magnetic Location) would be used to identify underground services. This data is presented as a record overlay onto a topographical survey or Ordnance Survey plan and output would be an agreed digital/cad layered format. A written report and photographic report would accompany the digital outputs.

Verification (Survey Type A)

This survey would involve exposing the target utilities within the survey area to confirm and record the location and depths of identified underground utility services. In addition, visual inspection of a service can be made by viewing manholes / inspection covers and excavation areas.
