Subsurface Utility Engineering – SUE

*NC DOT Approved

We have been analyzing, planning, and designing utility systems for over 40 years.

Municipal Engineering utilizes a non-destructive air vacuum excavator to prevent damage when locating underground utilities and structures.

Using SUE, Municipal Engineering can identify underground utilities such as:



Power



Drainage



Gas / Propane



Communication



Water / Sewer / Steam



Fiber Optic

Municipal Engineering is staffed and equipped for all four quality levels of SUE.

In 2003, the American Society of Civil Engineers (ASCE) published Standard 38-02 titled Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data. The standard defined SUE and set guidance for the collection and depiction of subsurface utility information. The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:

LEVEL A – NON-DESTRUCTIVE AIR VACUUM EXCAVATION

Level A is the highest level of service and provides the highest level of accuracy. With the use of air-vacuum excavation, damage to underground utilities traditionally caused by other digging methods is eliminated. By knowing the exact location of utilities, the designer can sometimes make small adjustments in the design that eliminate the relocation of utilities. NON-DESTRUCTIVE AIR VACUUM EXCAVATION is used to determine the exact horizontal and vertical location of utilities and allows the documentation of the utility type, material, size, depth, condition, location, orientation, etc.
