Atlanta Utility Locating Projects that Penhall Worked On

Locate underground utilities to complete your project safely

Atlanta utility locating Before a local business could expand their driveway, a portion of the existing parking lot needed to be removed. The client asked Penhall Technologies to locate all utilities within a 30’x 120’ area along the edge of the parking lot. The analyst started by clamping directly to any risers or transformers on site with his RD71000 unit. He then used the RD 7100 to trace out the signal into the scan area. The analyst also used the GSSI UtilityScan to confirm any findings. The hazards found were an electric line running through the middle of the lot, and a storm drain that reached a junction along the outer edge.  The analyst marked each utility with spray paint and marking flags. Upon completion of the scan, the customer was happy with the results.

Locate electrical lines and utilities before cutting into concrete

private utility locateA customer needed to locate all utilities below a sidewalk in a parking lot before an overhead canopy was built. In order to install the columns that would support the canopy, it was necessary to saw cut out portions of the sidewalk. In this scenario, a transformer that fed all exterior light posts was only a few hundred feet away from the scan area. This meant that it was likely that electrical lines were buried beneath the sidewalk. Using the RD 7100, Penhall was easily able to trace out and mark the electrical line. After that, we used the GSSI UtilityScan to determine that no other utilities were present in the scan area. The electrical line ran directly under one of the locations marked for a saw cut, meaning this quick locate likely saved the contractor an expensive and time consuming repair, and helped avoid a dangerous situation.
