Solicitation W9128F14B0025, issued by the Department of Defense through the W071 Endist Omaha office, concerns the installation of a new outlet pipe system for 14 relief wells located on the downstream side of Cherry Creek Dam in Arapahoe County, Colorado. The scope of work includes connecting six wells at the toe of the dam to an existing 30-inch CMP collector pipe using 6-inch diameter PVC outfall pipes. An additional eight wells located north of the CDOT right-of-way fence will be connected via 6-inch outfall pipes to a newly constructed 1,370-foot long, 18-inch diameter PVC collector pipe. All piping will be installed at depths between 10 and 25 feet and will feature stainless steel pipe tee connections at the relief wells. The project further requires the installation of two new RCP manholes and the relocation of approximately 2,500 feet of 6-foot high chain-link fence, moving it 30 feet north of the existing right-of-way fence. With an estimated construction cost ranging between 250,000 and 500,000 dollars, the contract was processed under NAICS code 237990. Bids for the project were opened on August 5, 2014, with submissions received from contractors including TZEC General Contractors, LLC and Kovillic Construction Co., Inc.
