Twin 72 Interceptor Replacement and Rehabilitation, Upper West Neuse Interceptor Replacement and Crabtree Interceptor Phase III Improvements

*Location 1 Twin 72” Interceptor Replacement and Rehabilitation This project involves the removal of approximately 17,900 LF of 72-inch sanitary sewer pipe and replacement with 72” and 78” sanitary sewer pipe via open cut methods and approximately 1,500’ of 72” CIPP between Walnut Creek Pump Station and Neuse River Resource Recovery Facility (NRRRF) along the Neuse River in Wake County, North Carolina. The project also requires the removal, bypassing, inspection, and reinstallation of portions of the existing 24” and 16” reclaimed water pipeline, sewage bypassing, manhole rehabilitation, manhole replacements, “In-situ” point repairs, forcemain abandonment, installation of a sewer plug valve vault, replacement of 3 CMP arch culverts with RCP box culverts, construction in easements and residential areas, construction near an active greenway and golf course, and grading and drainage improvements. The total estimated cost of construction is $52.5 million. This project is expected to advertise for construction in the Fall of 2021 and the construction contract period is expected to be 540 days. *Location 2 Upper West Neuse Interceptor Replacement This project involves the construction of approximately 12,000 LF of 60-inch sanitary sewer pipe along the Neuse River in Wake County, with the downstream end of the project located near the confluence of Beaverdam Creek and the Neuse River. The project requires one open cut crossing of the Neuse River, two trenchless crossings beneath NCDOT roadways, construction in residential areas, construction along an active greenway, and construction in floodplain areas. The total estimated cost of construction is $15 million. This project is expected to advertise for construction in the Summer of 2022 and the construction contract period is expected to be 360 days. *Location 3 Crabtree Interceptor Phase 3 Improvements This project involves the installation of approximately 18,000 LF of 54-, 48-, 42-, 36-, 24-,12-, 8- and 4- inch gravity sewer, ranging up to 38 feet in depth. Installation methods include open cut, bore and jack, and dual pass micro-tunneling. This project also includes incidental replacement of approximately 250 LF of 12-inch water line and appurtenances and 1,400 LF of 8- to 30-inch storm sewer pipeline, inlets, and other storm water devices. The project will involve sewage bypassing; sewer pipeline and manhole abandonment; aerial sewerabandonment; incidental utility relocation for telecom, electric, and other buried utilities lines;stream crossing restoration; road replacement; handling of contaminated materials and groundwater; traffic control; construction in easements, commercial areas, and residential areas; vibration monitoring; temporary fencing; erosion & sediment control measures; and other incidental items to make a complete project. The total estimated cost of construction is $44.2 million. This project is expected to advertise for construction in the Summer of 2022 and the construction contract period is expected to be 730 days.
