Texas Substation Owners Install Communications Safely with Accurate Subsurface Data

• The client needed to confirm the location of underground electrical lines and the substation’s grounding grid before installing a new communication tower
• Without an accurate layout of the grounding grid, the risk of striking the grid or other utilities was high

• GPRS Project Managers utilized an electromagnetic (EM) locator and induction clamps to verify the location and depth of the electrical lines
• They also used ground penetrating radar (GPR) with the induction clamps to identify the location and depth of the grounding grid
• They marked all their findings with red spray paint on the ground and documented them using GPS technology to create a digital map of the markings, which they uploaded into SiteMap for immediate use by the client

• By verifying the location and depth of the subsurface lines, the project could progress safely
• The client received the scan results the same day, keeping their project on time
• With the scan results only a click away on SiteMap, they can analyze and reference the data during projects in the future
