Subsurface utility locating and mapping services are responsible for eliminating and reducing damages to underground utilities during any kind of excavation. These services are also critical to a project’s initial design and civil engineering phases.
National Underground Group locates underground utilities, including gas, water, sewer, electric and fiber optic lines, for municipalities and utility owners and their engineers. In addition, we offer our utility locating services to homeowners and contractors.
Locating and mapping of utilities are accomplished through a variety of methods, including identification of and contact with utility owners within the project limits; detailed investigations of available records, plans and maps; thorough electronic searches of the site for buried facilities; and accurate mapping of all locatable subsurface utilities.
Utilizing the latest in surveying technology combined with utility records research results in identifying the precise horizontal and vertical coordinates of all structures. We accurately map the locations of buried pipes, utility lines and cables. Pinpointing the exact horizontal and vertical coordinates of each structure allows the rerouting of new utilities at the project planning stage and helps prevent damage and explosions.
