Private Utility Locating Project - Near Detroit, Michigan

A general contractor had a project at a Military Site in Warren, Michigan where they needed to dig a long trench behind the building to run electrical conduit. It was unknown of the path of the existing electrical. The general contractor had to connect the future electrical conduits to the existing electrical feed. Prior to proceeding it was essential they had information to which direction the existing electrical was running so they could tie into it & also so they didn’t compromise it during the construction process. The general contractor also needed to know if any other existing utilities were present before proceeding with the trenching to ensure the safety of everyone involved.

Ground Penetrating Radar Systems of Michigan was contacted by the general contractor to investigate the proposed trenching area to locate any underground utilities. GPRS first investigated their surroundings to locate any above ground manholes to get an idea of what possible utilities may be in the area. They utilized a 400 Mhz antenna which has the capabilities of reaching depths of 8ft. depending on soil conditions. An RD-8000, which is a radio detection device, was also used to perform the investigation. GPRS was able to locate the existing electrical feed & also a couple of other unknown utilities passing through the proposed area of excavation. They communicated the findings with the onsite Superintendent to ensure everyone was on the same page.
