GPRS locates utilities for a new foundation install in Pittsburgh, Pennsylvania

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to the installation of a new foundation at a plant in Pittsburgh, PA.

GPRS was tasked with locating any underground utility on site such as: gas, water, storm, and communication 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 (350 MHz antenna and EM locator).

Utility Lines Found Using Radio Detection and GPR

The site photos above depicts the main run of gas and water to this section of the plant. We were able to hook onto them using radio detection and then later confirm the accuracy and depths using Ground Penetrating Radar. With the Information provided by GPRS with locations and depths of these utilities that ran through the proposed location of the new foundation the client was able to review the specs of the project to safely work around our findings.

Utilities Located using GPR and EM Pipe Locate

Some of the utilities on site were located with both ground penetrating radar and radio detection. We have pictured above a communication and storm line crossing in the same area. These were marked out with paint and depths provided. These lines were nearby the new foundation locations but did not enter the proposed area. Thanks to our diligent efforts to locate all visible nearby utilities we were able to ensure the contractor these would not interfere with their work.

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.
