4636-23 NC61 WL Project Manual Certified for Bidding_09052025.pdf

The document is a Project Manual for the NC Highway 61 Water Line Extension, involving the City of Greensboro, City of Burlington, and North Carolina Department of Transportation (NCDOT). The project encompasses approximately 7,200 linear feet of 12-inch ductile iron pipe, with additional 8-inch and 6-inch ductile iron pipe installations, and includes two horizontal directional drilling (HDD) lines under Lake Mackintosh - one as a Base Bid (HDD-1) and the other as an Alternate (HDD-2). The project requires water main interconnect relocation between Greensboro and Burlington, with traffic control mandated under an approved NCDOT encroachment permit.

The project is financially supported through American Rescue Plan Act (ARPA) funds administered by the North Carolina Department of Commerce. The total project extends approximately two miles along NC Highway 61, starting from the south side of the Interstate 40/85 interchange. The specific construction approach involves precise pipe installation techniques, including standard trenching and horizontal directional drilling, with careful consideration for existing infrastructure and environmental conditions around Lake Mackintosh. The comprehensive water line extension project represents a significant infrastructure improvement initiative for the region, leveraging federal pandemic recovery funding to enhance municipal water infrastructure.
