GPR Scanning to Locate After Contractor Hits Post Tension Cable - Melissa, TX

Ground Penetrating Radar Systems, Inc., was contacted by a general contracting firm that needed to have several locations of a concrete slab scanned. The store front renovation project called for several sections of concrete to be saw-cut, and to keep the job-site safe and to avoid damaging the structural integrity of the building it was importantl that the contractor had reliable information on the locations of all of the post tension cables.

Prior to calling GPRS, the contractor hired of our competitors to locate the post tension (PT) cables. However, it became very clear that several of the PT cables had been missed by the scanning company. During the initial saw-cutting process, a PT cable was hit. The cable was “nicked”, and a large rumbling was felt throughout the entire building. As a result of this issue, the contractor was forced to halt all of their operations. To ensure that the project could completed without any more delays, the contractor decided to call the Experts in GPR: GPRS of Texas.

GPRS Inc., Project Manager, Gasten Schoonover was contracted to rescan the areas where the saw cutting was going to be performed. The customer also asked us to determine the location of the PT cable that was hit during the initial saw-cutting process. By using Ground Penetrating Radar equipment, we were able to accurately mark out all of the post tension cables within the areas of concern. Additionally, we were also able to locate several inaccuracies in the work of the previous scanning company. Further, numerous unmarked post tension cables were located directly in the locations of the planned saw-cutting area (where the initial PT cable had been hit). Thanks to the fact that we use industry leading equipment, and that we are able to provide a quick response time, a rapid turnaround, and high quality work, all of the post tension cables were located, and job-site operations were resumed. Most importantly, we were able to keep the job-site safe by ensuring that all of the post tension cables were located, and that a 2nd post tension cable would not be hit once saw-cutting was resumed.
