A new roundabout is coming to the high-accident intersection of Rocky River Rd and Kistler Farm Rd in Mooresville. The CESI SUE team provided detailed underground utility marking to support the civil engineering and construction processes. The project fell within the NCDOT Right of Way, so our teams took the appropriate measures to signal oncoming traffic of the location efforts by placing crew working signage at the beginning and end of the project. The location task included coordinating with local municipalities and utility providers to gather utility plans and then to perform a field investigation to identify and mark the existing underground infrastructure, such as gas, water, electric and telecommunication lines. Utilities were marked using industry standard colors. Our survey teams then located and mapped the locations, and provided a detailed survey showing the locations and connectivity.
