GPRS Locates Underground Electrical Lines in State College, Pensylvana

A general contractor needed to locate utilities prior to excavating. The contractor knew there were multiple high voltage lines in the path of the proposed trenching line, as well as some grounding they didn’t want to disturb. The contractor was preparing to excavate approximately 200 linear feet within an electrical substation in State College, PA. The estimated depth of the trench was 36 inches. The client reached out to Ground Penetrating Radar Systems, whicho specializes in underground utility locating. Sam Hart, who covers the Central Pennsylvania area for GPRS, was the project manager on site who was able to assist the client with this project. He located the grounding grid which was approximately 18 inches deep. He was also able to locate multiple electrical conduits at various depths which originated at the Trenwa. These conduits branched out from the Trenwa to multiple structures in the substation. There was also a conduit to a light pole within the proposed trench line. He marked all findings on the surface as well as their depths for reference. The EM pipe locator was used to locate the grounding and conduit in the substation. The GPR antenna was used to trace out the fiber optic cable that was in the substation. The GPR unit was also used for depths.
