This project generally consists of the removal of the existing concrete masonry unit wingwalls and concrete channel/walls at the ends of the existing ACCMP arch culvert. The existing ACCMP culvert is to remain in place but both ends of the pipe will be cut off. The portion of the culvert to remain will be cleaned and a new spray coating applied. Flowable fill will be installed over the culvert due to shallow existing cover. New concrete cut-off walls, headwalls and a new concrete channel/walls at the inlet will be constructed. The work also includes storm drainage and roadway reconstruction, placement of metal beam rail, associated regrading, riprap, turf restoration and other miscellaneous site work. The work described above includes furnishing, installing and incorporating all materials and equipment into the project as well as performing or providing all labor, supervision, equipment and services unless otherwise noted within the bid documents for the lump sum base bid.
