PAS 128 Cat D – Desktop Utility Record Search

This survey is a Search and Collation of existing records that are available.

Developments, feasibility studies and most on site works require some sort of utility survey to establish the location of assets such as pipes and cables. The first step in utility location is to write to the utility affected by your project and request a plan of their apparatus. If your company follows:

– British Standards Institution PAS 128, Specification for underground utility detection, verification and location
– HSG47 Avoiding danger from underground services
– The Construction (Design and Management) Regulations 2015

You could spend several weeks writing many individual letters to various utilities chasing up payments to these utilities and waiting on potential missing plans. This is time consuming, frustrating and not a good use of your time. Subscan UDS offers a Utility Search service, this gives you the opportunity of ordering all your utility search information from your desktop.

Which suppliers are included in a survey?

A Subscan desktop survey report sources responses from an average of 90 suppliers to ensure that you receive details on every supplier within your site area. The suppliers contacted operate in the areas of:

  • Gas supply
  • Water and sewerage supply

  • Oil and fuel supply
  • Telecommunications and cabling
  • Transportation and infrastructure, including:
  • Network Rail
  • Crossrail
  • London Underground
  • Transport for London

Survey Deliverables

Our Utility Search includes the identification of Utility Providers/Suppliers within your site. Copies of the Utility Providers/Suppliers record information (Stats) are then obtained and collated into a PDF Report or an AutoCAD Drawing (If Requested), depending on your requirements. This information can then be overlaid onto an existing topographical survey drawing.
