Ground Penetrating Radar Systems was recently called by a local construction engineering firm to help analyze a concrete slab for future construction planning in Dayton, Ohio. The contractor needed to know information such as slab thickness, rebar spacing, and conduit presence. The building was extremely old and little information about the slab composition exists. GPRS was able to identify the information the client was looking for as well as mark additional obstructions such as beams and conduits that were not thought to be present. Ground Penetrating Radar Systems was able to identify clear areas where the contractor could safely drill and take a core sample for further testing. The relevant details of the slab were then saved, and a detailed report was handed over to the client with the findings. 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. GPRS can also perform after hours services upon request to meet our client’s needs.
Ground penetrating radar findings after scanning
The photo above depicts GPRS’s standardized markings. Findings were marked directly on the surface using marker. Multiple obstructions were marked in this area including beams, joists, and rebar. GPRS was able to identify several open areas for the general contractor to core drill through safely. The contractors were informed to stay 1” off all markings to avoid striking rebar, beams, or conduits. 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. The detailed report provided was used to help the client determine the future construction plans for the building. This report was returned to the client within 3 business days.
