Industrial Facility Scanned for Utilities Prior to Digging a Trench

GPRS of Michigan was contacted by a general contractor to investigate a proposed trenching area to locate any underground utilities at an industrial facility in Detroit, MI. The general contractor had to connect the future electrical conduits to the existing electrical feed and it was unknown if any existing utilities were in the path of the proposed trenching area. It was essential for them to know which direction the existing electrical was running so they could tie into it without compromising it during the excavation process. They also needed to know if any other existing utilities were present before proceeding with the trenching to ensure the safety of everyone involved.

GPRS first investigated the surrounding area to locate any above-ground manholes to determine what possible utilities may be in the area. GPRS Regional Manager, Thad Bullock utilized a 400 Mhz antenna which has the capabilities of reaching depths of 8ft. depending on soil conditions. The RD-8000, which is a radio detection device, was also used to perform the investigation to ensure everything had been identified. GPRS was able to locate the existing electrical feed as well as some other unknown utilities passing through the proposed area of excavation. Thad was then able to interpret his findings with the onsite Supervisor who then had the confidence to begin the trenching project.
