Edgar Mine Sewer Line - General Contractors - Colorado School of Mines

The Colorado School of Mines is seeking general contractors for the Edgar Mine Sewer Line project, a design/bid/build procurement located in Idaho Springs, Clear Creek County. The project involves installing approximately 1,250 linear feet of HDPE sewer line down an existing road at the Edgar Mine site, with potential blasting requirements. Bidders must attend a mandatory pre-bid conference on September 24, 2025, at 3 pm and submit sealed bids by October 8, 2025, at 2:00 PM. Contractor qualifications include being in business under the same name for two years, demonstrating experience with similar projects, and showing bonding capability up to $500,000. Evaluation criteria will focus on selecting the lowest responsible bidder, with consideration given to Colorado resident bidder preferences. The anticipated construction timeline spans from November 1, 2025, to January 15, 2026, with potential liquidated damages for project delays. Bid documents require a 5% bid bond for construction values over $50,000 and comprehensive documentation of project approach and capabilities.

The procurement includes specific labor requirements mandating at least 80% Colorado workers and adhering to prevailing wage standards. No specific set-aside designations for disadvantaged enterprises were explicitly detailed in the documents. The estimated project budget is approximately $300,000, with contractors required to provide payment and performance bonds of not less than 50% of the contract value if the contract exceeds $150,000. Bidders must also comply with state regulations including environmental product declaration requirements and the Buy Clean Colorado Act provisions. A notable bid alternate allows for potential cost savings if mining staff can perform blasting services instead of the contracted general contractor. The project will be funded through the State of Colorado's Office of the State Architect State Buildings Program, with a virtual public bid opening to be conducted via Zoom and award intent notification anticipated for October 10, 2025.
