GPRS Locates Utilities Prior to Soil Boring at a Gas Station Outside of Columbus, OH

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to the installation of several concrete caissons. The environmental company on site knew that some of these locations were close to potential underground electrical lines, as well as potential unknown utilities.

GPRS was tasked with locating any underground utility on site such as: electric, storm drains, and potential unknown utilities. 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 some of the electrical lines we located, this particular location was clear of any utilities or obstructions. When we arrived on site, we discussed what needed to be done and walked the site. The site contact conveyed that their primary objective was to install three soil boring locations, and wanted to go ahead and clear those locations, as well as the concrete pad for future drill locations. We were able to mark several conduits, drain lines, fuel lines, and unknowns throughout the area.

Several Conduits and Unknowns Found Using Radio Detection and Ground Penetrating Radar.

The site photo above depicts several conduits, we marked it using red paint. We were able to locate this using radio detection, and then later confirmed while using ground penetrating radar. The contractor on site was interested in locating any utilities and obstructions throughout the concrete pad. We utilized ground penetrating radar and radio detection wands to clear all three locations prior to the contractor drilling as well as located other utilities and obstructions within the concrete cut out.

Electrical Conduit, Fuel Lines, and Unknown Utilities Located on Site.

Some of the utilities on site were located with both ground penetrating radar and radio detection. We were able to locate the electric, fuel lines, and drain lines, as well as clear the locations of any other unknown utilities prior to drilling. The contractor was able to drill and proceed with all of the locations that day. With the information provided they were also able to map and identify future drill locations.

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.
