The Colorado Division of Reclamation, Mining & Safety, under the Department of Natural Resources, issued a sealed bid invitation for the Lancaster Project (PKA-16-771), a mine reclamation effort located on Collier Mountain near Montezuma in Summit County, Colorado. The procurement encompasses comprehensive reclamation of the Lancaster Mine complex's lower, middle, and upper waste rock dumps, including construction of rock containment berms, consolidation and in-situ treatment of contaminated mine waste with pulverized limestone and compost amendments, installation of sediment control measures (Ertec S-Fence and straw wattles), debris removal, site grading, ditch and channel construction, revegetation of 1.5 acres, and storm water control installation. Key deliverables include mobilization/demobilization, development of a comprehensive project safety plan addressing hazardous materials handling and multiple safety protocols, debris removal of up to 60 tons, and optional line items for cement, additional excavator time, and supplemental limestone. The project must be completed within 47 calendar days, with construction scheduled between August 29, 2016 and October 14, 2016, and the original bid submission deadline was July 18, 2016 at 4:00 p.m., later amended to July 25, 2016 at 4:00 p.m., with bid opening on July 26, 2016 at 10:00 a.m. A mandatory pre-bid meeting and site showing occurred on June 30, 2016 at the Peru Creek Trailhead parking area. Sealed bids in a single copy were required to include completed bid forms with manual signatures, priced bid schedules for all line items, a bid bond of at least 5 percent of total bid price, and equipment lists. Award criteria specified the lowest responsive and responsible bidder, with performance and payment bonds equal to 100 percent of the contract price required for bids exceeding $50,000, and liquidated damages assessed at $400 per day for schedule delays.
Bidders with a Below Standard performance rating in the Colorado Contract Management System for any construction project completed for Colorado within the preceding five years were ineligible to respond. The project is funded through Federal grant money via CFDA 10.693 (USDA Forest Service) and Colorado Severance Tax collections, with all funding designated as USFS/Sev. Tax. No specific set-asides for disadvantaged enterprises, small businesses, or other protected categories were identified in the procurement documents. Seven Colorado-based contractors attended the pre-bid conference on June 30, 2016, including Epic Construction & Environmental, RMC Consultants, Berry Trucking & Excavating Inc., McCollum Excavating, Dave Enterprises Inc., H-2 Enterprises, and Roy Reynolds Secure On-Site. No incumbent vendor or current contractor information was provided in available documentation. The contract value was not explicitly stated in the procurement documents, though the requirement for performance and payment bonds on bids exceeding $50,000 and retainage terms (10 percent for bids between $50,000 and $149,999; 5 percent for bids of $150,000 or more) suggest the anticipated contract value likely fell within a six-figure range. Execution of the contract and all required documents was mandated to occur within ten days of the Notice of Award.
