Do you know what Subsurface Utility Engineering is?

SUE is a branch of engineering practice that combines civil engineering, surveying and geophysics in a process to manage certain risks associated with the following:

• Existing Utility mapping at appropriate Quality Levels (QL)

• Utility conflict analysis

• Communication of utility data to concerned parties

SJB provides in-house SUE services on all four quality levels D, C, B, and A, in general accordance with the recommended practices and procedures set forth by the American Society of Civil Engineers (ASCE) Publication CI/ASCE 38-02 (Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data). The four quality levels are separated based on accuracy of information and are detailed in the following pages along with examples of deliverables SJB can provide.

SJB’s Utilities staff has provided SUE services on hundreds of projects involving transportation, infrastructure, airports, water districts, seaports, bridges, hospitals, industrial plants, construction sites, light rail, prison facilities and schools. Existing utilities mapped include, but are not limited to CATV, telephone, fiber optic, electric, gas, water, sanitary sewer, storm drain, force main, product line, and reclaimed water.
