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.
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.
From residential storm lines to large-scale drainage infrastructure, our NASSCO-certified staff use Envirosight® pole cameras and Minicam Proteus® crawlers to locate, inventory, and assess conditions within otherwise inaccessible water and stormwater pipes. These systems provide detailed reports, including video, images, and measurements.
Improving what people depend on isn’t just our mission—it’s who we are.
