Ground Penetrating Radar Systems, Inc. scans for conduits and reinforcing steel prior to Electrician core drilling in Columbus, Ohio

Ground Penetrating Radar Systems was recently called by a local electrician to help assist in the installation of a couple concrete core drilling locations in Columbus, Ohio. The electrician needed to core drill through the slab to install a couple conduits. Ground Penetrating Radar Systems was able to identify clear areas as well as mark and identify reinforcing steel and beams located in the slab. Providing the electrician with as much information as we can directly assists with a safe and speedy project. While we identified multiple obstructions throughout their area of concern, we were also able to tell them an approximate slab thickness. All this information prevents delays on the project and keeps people safe. Striking a conduit can cost a contractor thousands of dollars in repairs, as well as potentially harming the workers drilling on site. Ground Penetrating Radar Systems, Inc. was able to get to the job in a timely manner which allowed the contractor to stay on schedule. Ground penetrating radar is an accurate and effective way of locating conduits, rebar, and post tension cables in a concrete slab.

Below you will find our standard markings for this project, we used sharpie to ensure a lasting deliverable in case of other delays on the project. We were able to identify several open areas for the general contractor to core drill through safely. We believe that all these marks represent possible rebar locations but conveyed to the contractor that these could be possible conduits and to be safe they should stay a minimum of 1”-2” of all our marks. We also identified several beams in our scans, we were able to mark these out and get the contractor to avoid these when drilling. By doing this we can ensure an efficient drilling process by avoiding the steel, beams, and conduits in the slab. This helps keep the project on schedule and prevents any unnecessary injuries that could be caused by striking a conduit with a drill. Since GPRS was able to arrive on site quickly and identify potential hazards in the slab prior to core drilling the general contractor was able to safely and efficiently core through the locations they needed.

Ground Penetrating Radar Systems, LLC. is very familiar with working closely with countless major commercial projects and contractors. Ground penetrating radar mapping is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes. Ground penetrating radar can also be used to locate underground utilities such as water, gas, electrical, communication, sewer, and other objects prior to digging or excavating.
