An Underground Services Survey or Utility Survey refers to the location, positioning and identification of buried pipes and cables beneath the ground. There are several techniques involved in locating underground services but the main ones include Electromagnetic locators (EML) and Ground Penetrating Radar (GPR).
PAS 128 provides a robust methodology for delivering utility surveys in the UK. It focuses on levels of accuracy – referred to as Survey Category Types – that you can specify when requiring a PAS 128 compliant underground utility survey.
