We performed comprehensive utility locating and subsurface mapping for a large industrial parking lot in Jackson, TN. Our team identified and marked critical underground infrastructure, including electrical ducts, storm lines, and power feeds, using surface spray and utility flags. We conducted manhole inspections and trenching to verify the exact location of buried assets across both asphalt surfaces and grassy embankments. The project concluded with the creation of detailed site maps featuring technical overlays of the subsurface network. These efforts provided clear guidance for site safety and future maintenance work without disturbing existing services.
