Solid Waste Center Grading and Civil Improvements

Pitkin County is seeking a qualified contractor to complete comprehensive civil construction services for the Solid Waste Center Grading and Civil Improvements project. The procurement involves approximately 100,000 cubic yards of civil grading, constructing a detailed stormwater system and 100-year storm pond, and installing a leachate pond system including specialized piping, liner installation, safety fencing, and electrical infrastructure. Proposals are due on May 21, 2025, by 2:00 PM MT, with a mandatory pre-proposal meeting scheduled for May 7, 2025, at 9:00 AM. The county will award a one-year contract with an anticipated start date of June 1, 2025, and project completion expected by December 2025. The evaluation criteria for proposals include 25% for project approach, 25% for similar work experience, 40% for estimated service costs, and 10% for references. Both primary contractors and subcontracted liner companies must demonstrate expertise in landfill liner systems, leak detection, and leachate management. Proposers are expected to align with the county's environmental priorities, focusing on climate action and carbon footprint reduction.

The procurement does not specify explicit set-aside designations or restrictions for disadvantaged enterprises. The project involves complex civil engineering work at an active landfill site in Snowmass Village, Colorado, requiring careful infrastructure integration and minimal disruption to existing operations. The total project scope encompasses approximately 10,406,338 cubic yards of earthwork, with comprehensive technical specifications for bid items including mobilization, phasing, quality control, earthwork, erosion control, and stormwater pond construction. While specific budget ranges are not explicitly detailed, the comprehensive nature of the project suggests a significant capital investment. The contract includes provisions for performance and payment bonds for contracts over $50,000, with a requirement that 80% of labor be Colorado-based. The project will involve extensive site preparation, including removing existing infrastructure, constructing new facility components, and implementing advanced environmental management systems for leachate and stormwater control.
