What is Subsurface Utility Engineering? Subsurface Utility Engineering (SUE) is a branch of engineering practice that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, utility design. (American Society of Civil Engineers, 2002)

The Safe Site, Colorado Subsurface Utility Engineering Process
The American Society of Civil Engineers (ASCE) has developed an important standard of care guideline, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data, CI/ASCE 38-02, Safe Site, Colorado respects and has incorporated these steps into their processes.
This standard guideline describes four quality levels of utility depiction:
Quality Level D- Information derived from existing records or oral recollections.
Quality Level C - Information obtained by surveying and plotting visible above-ground utility features and by using professional judgment in correlating this information to Quality Level D.
Quality Level B - Information obtained through the application of appropriate surface geophysical methods to determine the existence and approximate horizontal position of subsurface utilities.
Quality Level A - Precise horizontal and vertical location of utilities obtained by the actual exposure and subsequent measurement of subsurface utilities, usually at a specific point.
(American Society of Civil Engineers, CI/ASCE 38-02)
