GPRS locates utilities in active substation in Western Ohio

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to the installation of new ground wires in an active substation. The substation was going to be staying active through most of the project and delays due to utility damages or other line-strike issues were a major cause of concern to the General Contractors on site.

GPRS was tasked with locating any underground utility on site such as: electric, drain, and ground grid. We provided the location of each utility with as much accuracy as possible and gave depth where applicable. The technologies used on this project included the standard locating equipment (400 MHz antenna and EM locator.)

Site photos taken of a new utility trench with ground grind located and identified in green, and electrical conduit identified and marked in red. When we arrived on site, we discussed what needed to be done and walked the site. The contact conveyed that their primary objective was to have us locate the ground grid so that they could install new grounding and tie into the existing; we were shown two utility trenches in which this needed to be done. Providing this knowledge to the general contractor let them stay on schedule and prevent any possible injuries from a line strike.



This site photo depicts several electrical lines leaving the utility trench. We were able to locate these using radio detection, and then later confirmed while using ground penetrating radar. The contractor on site was interested in locating the ground grid, but wanted to avoid and identify any possible electrical lines near the area of concern. We utilized the transmitter and radio detection wand to primarily identify and mark out any grounding cables along the utility trench.

Some of the utilities on site were located with both ground penetrating radar and radio detection. We have pictured above a drain line and an electrical line running side by side. These were marked out with paint and depths provided. We were able to locate and identify several grounding wires, which the contractor was mainly interested in.

Ground Penetrating Radar Systems, LLC. is very familiar with working closely with countless major commercial projects and contractors. Ground penetrating radar 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.
