Utility Locating
To ensure the overall, timely success of the job, utility detection is critical to any construction project where subsurface excavation is planned. If ignored, budget overruns can multiply, your schedule can turn chaotic, and there's the risk of injuries taking place on your job site.
Concrete Scanning
With new build construction and renovation projects, the likelihood of needing to cut or core a concrete slab is high. This means there is an inherent risk of striking rebar, electrical and communications conduits, and post tension cables during the cutting, coring or drilling process. The cost of such mistakes can be high. Unreasonable constraints on already thin budgets can occur, as well as infusing havoc into your schedule and creating a safety hazard for your employees.
Pipeline Inspection (CCTV)
Introducing a new versatile technology to the GPRS family. The in-line crawler inspects the inside of pipes/culverts 6" - 96" in diameter. It can reach up to 1,000LF from the insertion point and features 360° pan and tilt. It can achieve zero-degree turning, track pipe grade and monitor temperature/pressure with onboard sensors. The in-line crawler offers digital video and images which can be exported via usb media or network port. GPRS offers this as a nationwide service and is operated by a NASSCO certified technician and offers NASSCO certified reporting.
