MBP provided full-time, on-site inspections for the installation of the two force main projects including constructibility reviews and cost estimating services. This project replaced approximately 14,000 linear feet of force main in downtown Norfolk along Colley Avenue and other adjacent streets to minimize the risk of sewer failures in these neighborhoods. The project consisted of replacing 5,000 linear feet of 48-inch ductile iron force main, 7,300 linear feet of 42-inch ductile iron force main, and 1,700 linear feet of 16-inch ductile iron force main. The 42-inch and 48-inch force mains serve all of southern Norfolk including downtown, portions of northern Chesapeake, and occasionally portions of Virginia Beach from the Military Highway area. The methods of operation for pipe installation included the open trench method, boring, and tunneling.
