GPRS locates utilities for excavation at a Pump Station in Pittsburgh, Pennsylvania

GPRS locates utilities for excavation at a Pump Station in Pittsburgh, Pennsylvania

Ground Penetrating Radar Systems was recently contracted to complete a site investigation prior to excavation inside a pump station in Pittsburgh, PA.

GPRS was tasked with locating any underground utility on site such as: gas, electric, and storm lines. We provided the location of each utility with as much accuracy as possible and gave approximate 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 depict markings of gas and electric within the proposed excavation section of the pump station. We were able to hook onto them using radio detection and then later confirm the accuracy and approximate depths using Ground Penetrating Radar. With the Information provided by GPRS with locations and depths of these utilities that ran through the proposed location the client was able to review the specs of the project to safely work around our findings.


Satellite Overlay Deliverable of Findings

Some of the utilities on site were located with both ground penetrating radar and radio detection. We have pictured above the deliverable provided to client for reference as the project and excavation move forward. These were marked out with paint and depths provided. Thanks to our diligent efforts to locate all visible nearby utilities we were able to ensure the contractor could keep the project on schedule and excavate safely.

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.
