A general contractor had a project inside of a Verizon Office where he needed to install Fios lines and push them through two 7 inch core holes within the building. It was essential, while core drilling the concrete, not to compromise any conduits or utilities within or beneath the slab. Prior to beginning the core drilling process, the contractor contacted Ground Penetrating Radar Systems of New England to scan the floor in order to locate all of the conduits and utilities that ran through the area and to locate any reinforcing in the floor. GPRS used a High Resolution 1600MHz Antenna that is able to scan concrete up to 18-22” in thickness with incredible accuracy of +/-1/4” on the location and depth of the anomaly.
After all of the conduits, utilities, and reinforcing were found around the proposed core holes, the general contractor had all of the information needed to proceed with confidence and safety. With the help of Ground Penetrating Radar Systems, Inc. this project stayed on schedule and was safely completed without any damage to conduits or the individuals coring the hole locations. If you have a project where you have concerns about striking reinforcing steel, conduits or post tension cables contact your local GPRS office to ensure your project is kept on time and done safely.
