Utility Engineering and Location Services

EST is committed to eliminate utility problems during construction for our clients, for them to feel confident that they will not have any project delays, and to reduce any possible change orders due to utility issues.


Utility coordination requires a careful & accurate survey needed to ensure exact locations and depths of underground utilities. With this being said, we are excited to announce our newest service, Subsurface Utility Engineering (SUE), which utilizes several processes, including surface geophysics and vacuum excavation (also known as hydrovac and/or potholing).


  • Provide precise location and depths of utilities
  • Unnecessary utility relocations are avoided
  • Reduces costly relocations (helps w/estimates)
  • Reduces delays to the project
  • Initial utility condition assessment

EST’s staff of professionals will facilitate and manage close communication with utility companies and our clients to ensure efficient and accurate design, plan development, and safe utility relocations to keep projects on schedule without delays. In-house licensed surveyors and CADD specialists will also provide support to help expedite construction and minimize costs.
