Task

Conduct full site utility locates for seven compression stations located in four states and deliver CAD files containing subsurface infrastructure data to the customer.

PROBLEM

  • The customer required comprehensive subsurface utility & infrastructure mapping data for seven compression stations in Ohio, Kentucky, Indiana, and Mississippi
  • Utilities located at compression facilities are complex and condensed, requiring precise and accurate measurements
  • Daylighting or potholing to identify utility lines posed additional risk for the customer due to the proximity of buried gas pipelines, so it was vital to utilize non-destructive testing & imaging (NDT)
  • The projects required an expedited turnaround time from field work to CAD delivery

Solution

  • GPRS Project Managers visited all seven locations to provide SIM-supported utility assessment and mapping
  • Electromagnetic (EM) locators were initially used, complemented by ground penetrating radar (GPR) deployed in a 5 ft. x 10 ft. grid pattern to capture every underground feature, including depths
  • GPS/GNSS Geodes were utilized to geolocate and upload precise geographical data to SW Maps & SiteMap®
  • GPRS’ Mapping & Modeling Team exported the geolocated utility data to create precise CAD satellite image overlays of all underground utilities which were also delivered via SiteMap®

Benefits

  • Thanks to SIM (Subsurface Investigation Methodology) the client was assured that each site would have the same level of precision mapping & measuring, regardless of location
  • GPRS’ national footprint and 500-strong elite team of SIM-certified Project Managers allowed for easy multi-state coordination and rapid response
  • In-house mapping & modeling provided by GPRS provided all necessary data to meet the clients one-month timeframe
  • SiteMap® allowed the customer to have secure, shareable 24/7 access to their utility data via the desktop and/ or SiteMap® Mobile App as a single source of truth for all team members
