Bid Schedule - Gold Creek Project.pdf

This is a bid schedule document for the Gold Creek Project, a state and local contract opportunity in Colorado administered through the Colorado VSS (Vendor Self Service) bidding platform. The project involves mine closure work across multiple sites with both U.S. Forest Service (USFS) and private ownership. Bidders are required to submit bids exclusively through the Colorado VSS online system, with mail and fax submissions prohibited unless VSS becomes unavailable and alternative methods are specified in the project's Special Conditions. The scope of work includes four main line items: mobilization/demobilization, development of a Project Safety, Health and Environmental Action Plan, installation of mine closures across 15 identified features, and provision of up to 9 cubic yards of additional polyurethane use fill (PUF) material on a non-guaranteed basis. The bid schedule, updated February 24, 2026, requires submission of all pages completed with line items filled in, and the bid must be signed by an authorized representative of the offeror.

The mine closure work encompasses 15 distinct features (labeled GC-01 through GC-15) utilizing two primary closure methods: bat grates with access doors for adits and polyurethane foam application for shafts and select adits. Bidders must provide individual bid amounts for each feature and calculate a total lump sum amount for Item 3.0, which consolidates all mine closure installation costs. The ownership of closure sites is divided between USFS properties and privately owned locations. All pages of the bid schedule must be completed and returned; amendments to any section are not permitted. Pricing is structured on a lump sum basis for mine closures with unit pricing for additional materials, though specific unit prices and total amounts are to be entered by the bidding contractor based on their cost proposals.
