Utility Locating Specialist from Ground Penetrating Radar Systems

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.

The standard is one-call utility locating, a state-operated public service that is required for every project. However, the scope of this service can be limited. To achieve the complete success you are looking for you’ll want to connect with an expert private service provider like GPRS.

We can offer you a comprehensive range of reporting options, from a basic field sketch to a full-blown AutoCAD report that will pinpoint buried electrical, water, gas, communication, sewer and storm drain lines. Our report will provide you with a permanent utilities location record for future reference. Learn More >

Ground Penetrating Radar Systems Specialist Performing 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.

Our well-trained, skilled, experienced technicians are accustomed to responding quickly to any service request, especially when your need for concrete scanning is a last-minute discovery. The end result is professional, accurate and timely scanning - exactly the satisfaction you are seeking to mitigate your risk and keep your employees safe. Learn More >

Featured Utility Locating Story

Providing Utility Locating Services At A US Steel Site

Ground Penetrating Radar was recently contracted to locate utilities at a US Steel site for installation of new fire water lines throughout the plant. The project was a multistage contract with approximately 5,000 feet of fire water line installed.

GPRS was given the task of locating all underground utilities and other items along the trenching path. With all of the vital lines for the production and safety of the plant underground, accuracy was a must for this project.

GPRS Locates Reinforcing Prior To Core Drilling

Our client had called Ground Penetrating Radar System to scan a concrete wall for reinforcing prior to core drilling in Philadelphia, PA. The client was extending a section of the roof and needed to core drill for utility access. The goal for GPRS was to locate and provide site markings of the rebar within the wall. The client had contacted the project manager for the Eastern Pennsylvania, Delaware, and Southern New Jersey area, Grant McGuigan.
