About this file
This is a revised bid schedule for the Mineral Mountain Mine Closure Project (IFB1 PKAA 2026-0104) issued by the State of Colorado. The project encompasses mine closure activities across multiple mining features including adits, shafts, stopes, and prospect pits at the Mineral Mountain site. Bidders must complete all line items on the three-page bid schedule without amendments. The scope of work includes mobilization and demobilization, project safety and health planning, sediment control (425 linear feet), installation of mine closures across 16 features using various closure methods such as machine backfill, hand backfill, concrete sealing plugs with bat ladders, and polyurethane foam injection, and safeguarding of additional hazardous mine openings. The bid schedule was last revised on March 10, 2026, with an update noted on August 25, 2025.
The bid schedule itemizes guaranteed and non-guaranteed work items with specified quantities and units. Guaranteed items include mobilization/demobilization, safety and health planning, and sediment control, while non-guaranteed items include additional wattle (25 linear feet), rockfill (5 cubic yards), concrete (5 cubic yards), polyurethane foam (10 cubic yards), imported fill (5 cubic yards), and machine time (10 hours). Mine features are designated as either privately owned or under United States Forest Service (USFS) ownership. Bidders must provide per-unit pricing for applicable line items and calculate total project costs. The bid schedule emphasizes that all pages must be returned and all line items must be completed for a submission to be considered responsive.
