North Landfill Cell 1 Construction

Larimer County is seeking a contractor for the North Landfill Cell 1 Construction project, a comprehensive municipal solid waste landfill cell development located in Wellington, Colorado. The project involves constructing a new 20-acre landfill cell with an engineered liner system, requiring extensive site preparation including clearing, grubbing, precise grading, and vegetation restoration. Bidders must submit electronically through the Rocky Mountain E-Purchasing System by December 5, 2024, at 2:00 PM Mountain Time, with a virtual pre-bid meeting scheduled for November 13, 2024, at 10:00 AM. Qualified contractors must demonstrate experience with at least three major landfill cell developments or similar earthwork projects of 15 acres or more, and three geosynthetic liner projects of similar scale, completed within the past seven years. The project requires a 5% bid bond, and the total project must be completed by October 31, 2025, with key milestones including excavation, base liner earthwork, geosynthetics installation, and leachate collection system implementation. The county will award the contract to the lowest, most responsive, and responsible bidder meeting all project specifications, with a total estimated excavation of 792,000 cubic yards and significant geosynthetic installations.

There are no specific disadvantaged business enterprise (DBE) requirements or goals for this project. The contract allows for participation from small and minority firms, women's business enterprises, and labor surplus area firms, with a requirement that at least 80% of work be performed by Colorado labor under the Keep Jobs in Colorado Act. The project involves significant infrastructure development, including installing a complex liner system with geosynthetic clay liner, 60-mil HDPE geomembrane, drainage geocomposite, and a leachate collection system. The total project budget includes a $400,000 force account allocation, with unit prices to be firm unless otherwise specified in contract documents. The site has two potential entrances and will require careful coordination with existing Western Area Power Administration transmission lines and Poudre Valley REA electrical infrastructure. Construction quality assurance and oversight will be provided by HDR Engineering, and the project will require obtaining a CDPHE General COR400000 Stormwater Discharges Associated with Construction Activity permit, with an anticipated notice-to-proceed date of January 6, 2025.
