Subsurface Utility Engineering

Subsurface Utility Engineering (SUE) is the investigation and identification of underground utilities. GUY provides SUE services to help project owners, utility owners, designers, engineers, and contractors understand the underground utilities that might affect their project. Using SUE technology, GUY can identify the precise vertical and horizontal location, size, and configuration of underground utilities before design and construction begins. Project designs can thus avoid unnecessary impacts to those utilities, reducing costly, time-consuming project delays.

GUY provides all four quality levels of SUE:

  • Quality Level D (Records Research / Data Collection)
  • Quality Level C (Above Ground Survey)
  • Quality Level B (Utility Designation)
  • Quality Level A (Test Hole / Pot Holing)
