    Highways

    Highway projects demand an accurate and complete understanding of subsurface data, with safety and efficiency at the forefront. ESP uses a high-speed GPR array (Raptor®) the first real-time-sampling (RTS) system capable of collecting 3D GPR images at posted speed limits. This tool increases production capability on large scale roadway utility mapping projects in terms of speed of data acquisition while improving safety margins for site personnel.

    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.

    Having a thorough understanding of underground utility infrastructure prior to design or construction saves time and money for construction projects, and, even more importantly, avoiding potential injury. Quality level D through A SUE and 3D GPR services in support of site construction is performed at critical locations to avoid damage to existing utilities during the construction.

    SUE services provide valuable information at the design and construction stages of single-family and multi-family residential developments.

ESP’s subsurface utility engineering (SUE) division applies the latest technology and methods to accurately map underground utilities for design/construction projects. The quality and accuracy of a subsurface investigation is based not only on the right equipment and techniques, but also on the experience of the people performing the service.

That’s why, in addition to its investment in non-destructive vacuum excavation equipment and geophysical/remote-sensing devices like ground penetrating radar GPR), ESP employs professional surveyors and engineers with more than 200 combined years of experience performing SUE services. Our high-tech equipment and qualified professional staff allow ESP to provide our clients with accurate and efficient SUE services ranging from Quality Level-D (QL-D) to QL-A.

ESP integrates a high-speed GPR array (Raptor®) as a tool within the SUE process.  The Raptor is the first real-time-sampling (RTS) system capable of collecting 3D GPR images at posted speed limits. This tool increases production capability on large scale urban utility mapping projects in terms of speed of data acquisition while improving safety margins for site personnel. 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.
