Subsurface Utility Engineering (SUE)

Lexis’ staff follow the American Society of Civil Engineers Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data.

The effective application of SUE has been demonstrated to reduce overall project costs in both the design and construction phases.  Accurate utility mapping early during the project lifecycle reduces redesign and unforeseen utility conflicts during construction.  Cost-savings per dollar spent on SUE for transportation projects range from $4.62 to $22.21 as found by independent studies performed by Purdue University’s Department of Building Construction Management (commissioned by the Federal Highway Administration) and The Pennsylvania Transportation Institute at The Pennsylvania State University (sponsored by the Pennsylvania Department of Transportation), respectively.


Our Team members have experience providing geophysical applications, specifically SUE services to a wide array of clients including transportation, state/local government, hospitals, site/land development, and the oil and gas industry.
