PKAA, Gold Creek Project

Pikes Peak Area Council of Governments (PKAA) is soliciting bids for mine closure work on the Gold Creek Project in Gunnison County, Colorado, with bids due August 4, 2026 at 5:00 p.m. Amendment No. 1 issued July 22, 2026 removes Item 3 (Install Mine Closures, feature GC-08) from the scope due to private landowner closure; bidders must acknowledge the amendment and submit the Revised Bid Schedule. This is a federal-funded construction project subject to Davis-Bacon Act prevailing wage requirements, Buy America domestic content preferences, and the Buy Clean Colorado Act environmental product declaration and Global Warming Potential limits.

The scope encompasses closure of 13 mine features (adits and shafts) located in the Parlin, Ohio City, and Pitkin vicinity, with 10 features requiring active closure work using three primary methods: steel grate installation with bat access, corrugated steel pipe bulkhead installation, and polyurethane foam filling. Features are distributed across United States Forest Service land and private property, with access ranging from roadside to remote sites requiring 300-plus feet of hiking over significant elevation changes. Feature depths vary from 7 feet to 300-plus feet; several features are historically eligible for cultural resource protection. Work requires detailed safety, health, and environmental planning; all contractor employees must complete orientation training and White-Nose Syndrome decontamination protocols for cave and mine work per U.S. Fish and Wildlife Service standards before commencing work.

Bidders must submit a completed List of Equipment Offered form identifying all equipment by manufacturer, model, serial number, and year. Bid items are mobilize/demobilize (lump sum), Project Safety, Health and Environmental Action Plan (lump sum), Install Mine Closures (individual pricing by feature), and Additional PUF (per cubic yard, not guaranteed). All costs for safety measures, equipment, training, and decontamination are included in the bid price. Submission is mandatory via Colorado's VSS online portal; mail and fax are not permitted unless VSS is unavailable. Bid opening is scheduled for August 5, 2026. The contract incorporates the Colorado DNR Model Construction Agreement, requiring minimum insurance coverage of $1 million per occurrence for commercial general liability and pollution liability, with the State named as additional insured.
