Subsurface Utility Engineering
Subsurface Utility Engineering (SUE) is an effective means of verifying and mapping the location of existing underground utilities. Collecting data from all available sources enables our licensed professionals to provide clients with the most complete information available. This includes employing a combination of geophysical methods, civil engineering, survey mapping, electromagnetic, ground penetrating radar (GPR) and nondestructive excavation technologies. SUE is a critical part of the design process for new and existing infrastructure projects that saves clients time and cost by helping to eliminate unexpected utility conflicts and unnecessary relocations while enhancing safety during construction.
Our professionals operate in accordance with the ASCE-38-22 Standard Guideline for Investigating and Documenting Existing Utilities. Our professionals address all four quality levels (A, B, C & D) and combinations thereof in accordance with the Standard and in conjunction with Survey/Geospatial, Utility Coordination and Utility Engineering to provide complete end to end utility solutions for our Clients. We work with DOTs, airports, railroads, transit, land development, building construction, all branches of government, utility owners and clients throughout the utility engineering process to develop an approach for each unique project type to confirm and resolve utility conflicts.
Colliers Engineering & Design SUE Professionals are very involved with standards development and industry groups including; the Utility Engineering & Surveying Institute (UESI), where our Team members serve on multiple national committees to improve standards and practices, and the SUE Association, where our Team members serve in leadership roles to advance understanding and utilization of the SUE Process.
