They set industry bench​marks, provide assurance and reassurance.

As a subsidiary of Survey Systems Ltd, Locate Surveys undertake utility surveys in accordance with the following:

  • The Survey Association: The Essential Guide to Utility Surveys

Detailed guidance notes for specifying a utility survey: Issue 4, October 2011

Specification for underground utility detection, verification and location

The current standards exist to guide clients towards a specification for their survey and allow the comparison of like-for-like quotations.

Both the Survey Association’s guide and the PAS128 specification document provide a ranking of utility surveys ranging from the most basic through to the most complex. Considerations such as objective, budget, terrain and location are key when considering survey types and techniques.

Using unfamiliar terminology can be a significant barrier to the appropriate use of these documents but Locate Surveys will work with you to establish the most effective specification for your site.
