Utility & Subsurface Mapping Services

Field-proven services built to reduce rework, support design teams, and streamline permitting across the U.S.

Subsurface Utility Mapping (SUM)

We deliver full-stack subsurface data using GPR, EM, and GPS tools. Our SUM process helps reduce strikes and streamline design and permitting plans. As part of our Subsurface Utility Engineering (SUE) services, we provide CAD-ready outputs and precise field data to support engineers, contractors, and municipalities.

Utility Test Holes (Vacuum Excavation)

We use hydro and vacuum excavation to verify utilities in the field. Clean test holes, SUE Level A data, and reduced risk for crews. Our test hole coordination and SUE verification eliminate compliance delays, reduce permitting risks, and keep projects moving.

“Nick’s team delivered clear, CAD-ready maps with zero back-and-forth. That alone made them more useful than most survey companies we’ve dealt with. Highly recommend.”

– Bill Reeves, Letter 88 Surveying

"SiteTwin’s crew was a game-changer for our deadlines. Their private locates were spot-on, fast, and cleared us to trench without waiting on 811. Easy choice every time."

– Nate Welch, Apex Construction

“SiteTwin’s data helped us avoid strikes on two major projects. Their GPR was accurate, fast, and the crew knew exactly how to work around our timeline. That saved us thousands.”
