3D Underground Utility Mapping Surveys

The term Utility Mapping Survey refers to the location, positioning and identification of buried pipes and cables beneath the ground. Other terms used for this type of survey include:

  • Service Tracing
  • Underground Utility Surveys
  • Underground Utility Mapping
  • Utility Detection Survey
  • CAT scan
  • Radar survey or GPR survey
  • Virtual Slit Trenching


3D Utility



There are many benefits which come from a well-executed utility survey including:

  • The safety of the workforce and public
  • Minimise utility damage
  • Minimise project delays
  • Save delay and damage costs
  • Designing and planning knowing the constraints
  • Saving costs with producing as built records
  • Reduces traffic management costs.
  • Reduces the amount of intrusive investigation such as slit trenching.
  • Gives the client an overall view as opposed to slit trenching which usually covers only a small % of a site.
  • Promoting good relationships between client and surveyor


What is involved in a utility survey?

The successful detection and mapping of buried utilities involves the combination of several techniques, the results of which are synthesised down to a single interpreted plot. The techniques and methodologies used will primarily depend upon the required outcome for the survey, the site conditions and the type of pipes or cables being targeted.
