GPRS locates utilities in active compressor pad in southern Ohio

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to the installation of new equipment at an active compressor pad. The compressor pad 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 the General Contractors on site.

GPRS was tasked with locating any underground utility on site such as: gas, electric, drain, and possible water lines. 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 what appears to be a wide-open area present in the existing compressor pad. When we arrived on site, we discussed what needed to be done and walked the site. The contact conveyed that this area was where they wanted to set the new equipment and that there wouldn’t be anything running through this area. During our investigation we located the main electrical line and several drains going through this area. Providing this knowledge to the general contractor let them stay on schedule and prevent any possible injuries from a line strike.


The site photo here depicts the main run of electrical conduits for the compressor pad. We were able to hook onto them using radio detection and then later confirm the accuracy and depths using Ground Penetrating Radar. Due to the number of conduits in this area we marked wider than normal and conveyed the likelihood of conduits being stacked on top of one another. The General Contractor conveyed that due to this information they would hydro excavate to be safe!

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 found that most structures on the pad had drain lines that all ran to a main trunk line.

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