PKAA, 1000, Poughkeepsie Gulch Mine Safety Closure Project

The State of Colorado, Division of Reclamation, Mining and Safety, is procuring comprehensive mine closure and remediation services for the Poughkeepsie Gulch Mine Safety Closure Project (PKA-15-745) located in San Juan County within Rio Blanco County and Denver City jurisdictions. This procurement encompasses the safe closure and reclamation of approximately 36 inactive mine features, including adits, shafts, and prospects, requiring specialized closure methods such as bat grates with access features, bulkheads, concrete footers, drain pipe systems, polyurethane foam closures, and corrugated HDPE pipe installations. Deliverables include mine closure design plans, environmental assessment reports, reclamation specifications, site preparation work, fabrication and installation of closure structures, and ongoing monitoring protocols, with work phased over an anticipated 18-24 month timeline dependent on environmental conditions and regulatory approvals. Required qualifications include demonstrated experience with mine closure projects and environmental remediation in similar geological conditions, appropriate environmental and safety certifications, and bonding and insurance coverage suitable for hazardous site work. Key objectives prioritize worker safety and environmental protection while accommodating wildlife habitat considerations identified at multiple sites by U.S. Forest Service wildlife biologists. A pre-bid meeting was held on September 16, 2014, with four contractors in attendance; the bid submission deadline was April 21, 2015 at 4:00 p.m., with bid opening scheduled for April 22, 2015 at 10:00 a.m. The original posting date was February 18, 2015, with Amendment No. 1 issued to clarify specifications and provide revised bid schedules via the VSS website.

No specific incumbent contractor or set-aside designations for disadvantaged enterprises are identified in the procurement documents; however, special consideration is indicated for contractors demonstrating substantial experience with mine closure operations and environmental remediation. The project does not reference existing infrastructure or technology requiring integration beyond compliance with Standard Work Specifications (SWS 11 and SWS 8) for grate installation, concrete footers, and drain pipe systems, and materials must conform to specified ASTM standards and American Welding Society standards for field welds. All work is funded through state environmental remediation grants and federal mining reclamation programs, with pricing submitted on a lump-sum basis for defined phases and potential cost-plus-fixed-fee arrangements for contingency work related to unforeseen mine conditions or contamination levels. Specific budget amounts are not disclosed in the procurement documents; however, the revised bid schedule identifies 28 individual mine features requiring various closure methods with itemized pricing requirements, and bidders must also provide optional equipment rental pricing for 16-hour excavator rental. Contractors are required to acknowledge receipt and acceptance of Amendment No. 1 on the bid form and submit bids to Teresa Ryan at the Colorado Department of Natural Resources, Division of Reclamation, Mining and Safety in Denver, Colorado.
