What is Subsurface Utility Engineering (SUE)

Subsurface Utility Engineering (SUE) services help project designers manage risks associated with surprise encounters with buried utilities which can bring construction projects to a complete halt. These services have been proven to reduce construction costs related to the risks associated with inaccurate or incomplete utility information.

 

We use state-of-the-art geophysical sensing equipment for identifying, designating, locating and mapping existing and abandoned utility infrastructure. Techniques include magnetic, sonic, and acoustic technologies, ground penetrating radar, and radio frequency detection.

 

Our experienced and highly trained staff includes engineers, surveyors, and technicians have successfully provided all four SUE quality level services to state, municipal, and private clients.

Quality Level D: Record Research/Data Collection

At this level, information is derived from records research or oral history. The D level of service can provide a "feel" for the overall congestion of utilities, but is often limited in terms of comprehensiveness and accuracy.

 

All SUE services are performed in accordance with ASCE CI-38-02.

Quality Level B: Utility Designation

Designation data is collected by thorough applications of appropriate surface geophysical sensing technology. Located utilities are marked, field-tied to project monumentation, and mapped onto plan documents.

 

All SUE services are performed in accordance with ASCE CI-38-02.

Quality Level A: Underground Utility Locating (Test Hole)

For this highest confidence level, precise horizontal and vertical locations of utilities are obtained using nondestructive vacuum equipment excavation to safely expose, measure and map utilities. Level A includes all other quality level tasks and conflict resolution.

 

All SUE services are performed in accordance with ASCE CI-38-02.

Quality Level C: Visible Surface Feature Utility Survey

At Level C, utility surface feature data is obtained from surveying and plotting aboveground utility features. Level C data supplements Level D data and finds omissions and errors in record information.

 

All SUE services are performed in accordance with ASCE CI-38-02.
