Subsurface Utility Engineering & 3D GPR

ESP’s subsurface utility engineering (SUE) & 3D GPR division applies the latest technology and methods to accurately map underground utilities for design and construction projects. In addition to investment in non-destructive vacuum excavation equipment and geophysical/remote-sensing devices like ground-penetrating radar, ESP employs professional surveyors and engineers with more than 200 combined years of experience performing SUE & 3D GPR services.

Our high-tech equipment and qualified professional staff allow ESP to provide clients with accurate and efficient subsurface utility mapping in accordance with ASCE Standard 38-22. With the ability to integrate data with survey and other SUE mapping deliverables, ESP delivers 3D data to mitigate utility conflicts and keep projects on schedule.

Subsurface Utility Engineering & 3D GPR Applications

High-Speed Raptor® 3D GPR

ESP employs a high-speed Raptor® ground penetrating radar (GPR) array, the first real-time sampling (RTS) system capable of collecting 3D GPR images at posted speed limits. Through its speed of data acquisition, this tool increases production capability on large-scale urban utility mapping projects while also improving safety margins for site personnel.

Benefits of High-Speed 3D GPR:

Eliminates need for traffic control
Reduces cost & time for efficient data collection
Increases safety for consultants & the general public
Minimizes time field personnel spend in the traffic corridor
Provides survey-grade position via RTK/GPS or total station
Collects large volumes of 3D subsurface data at posted speed limits
Allows conversion of post-processed 3D data into line data for CAD export that depicts utilities in a 3D survey
