GPRS Locates Utilities In Cleveland, OH

GPR Utility Scanning Used to Locate Underground Utilities in Cleveland, OH

GPRS (Ground Penetrating Radar Systems, Inc.) was recently hired by a local contractor during a project where they are remodeling 16 suites in a downtown Cleveland apartment building. Prior to our arrival, the contractor saw cut through live electrical conduits in the concrete slab. The electrical and communication conduits had no set pattern or drawings to give the contractor an idea of where they were in the floor. The contractor contacted GPRS in order to determine where the conduits were located along with the steel beams so that they could saw cut the floor between the beams. Once we arrived at the site, we walked the area of concern (area to be scanned) with the onsite contact and discussed the areas still requiring saw cutting. This was done in order to determine the exact scope of the job and how the contractor would like the findings marked. GPRS has the capability to mark findings with marker, crayon, paint, tape and even a drawing if requested. This site requested to paint the findings out using white paint for the beams and red for the conduits. Upon completing the walk-through, we were ready to scan using Ground Penetrating Radar (GPR). We set-up and calibrated our 1600MHz antenna and GSSI SIR-4000 unit and began scanning first for the beams in the floors. Once the beams were marked out, GPR was then utilized to find the conduits throughout the entire suite. Most of the time the GPR was able to take the conduits back to the source to help the contractor determine if the conduits were active or dead. Next, we used our EM Pipe Locator to confirm live electrical conduits. We were able to use the circle clamp and the 3-pronged adapter that will put a tone on an existing electrical line in order to locate it. At the conclusion of the investigation, we did a final inspection of the concerned area to explain all the findings and be sure the contractor understood the markings. GPRS also has the capability of marking the approximate depths of the conduits, but was not necessary at this job site. The first image below shows part of suite 902 with the white marks showing the beams and the red showing the conduits and the direction they are heading. The remaining images depict onsite photos of a few more of the suites scanned as well as our surface markings of beams and conduits are located. It is important to call GPRS and have each area being saw-cut or excavated scanned with GPR prior to any work being done. In this case, we were able to help the contractor avoid any further damage to the existing conduits. The Contact number for this area is David Abdul 330.815.7860, david.abdul@gprsinc.com for any of your concrete or utility scanning needs.
