Managing Construction in Established Raleigh Neighborhood

The City of Raleigh had annexed the Bentley Woods subdivision in two different phases and needed to extend water and sewer services to the area. Our teams assisted in the design of the utility extension for both phases, where 23,000 LF of 8 inch gravity sewer was extended and 21,000 LF of 6 through 12 inch water line was replaced in Phase 1, and 7,500 LF of 8 inch gravity sewer and 5,000 LF of 6 inch water line were extended in Phase 2. Since the project areas were provided water services through Asbestos Cement (AC) water lines, the project also involved abandoning these waterlines in place (pressure granted) and replacing them with new Ductile Iron water lines. The project was located in a well established neighborhood built in the 1970’s which made design and installation of the new utilities even more challenging as priority was placed on minimizing any impacts to its residents.
