Completed plans call for the construction of a 5,900-square-foot, one-story above grade office development; industrial development; for the demolition of a industrial development; and for site work for a industrial development.

Dane County is seeking bids from qualified contractors for the RNG Maintenance Shop and Office Building, located at 7202 Maahic Way Madison, WI 53718. This project involves the construction of a combined office and maintenance shop building to service the needs of the Renewable Natural Gas (RNG) Facility located at Dane County Landfill Site No. 2, and the demolition of the existing maintenance shop upon completion of the new building, and is being delivered under a lump sum contract. The goal is to upgrade outdated infrastructure and provide RNG staff with permanent office space and a break area. Work must be performed in coordination with landfill operations and RNG facility operations, and must comply with all applicable county specifications, ordinances, local permitting requirements, or prevailing wage laws. Interested vendors should have demonstrated experience in site civil and building construction and the ability to manage projects of similar size and complexity. Key considerations for vendors include the limited available staging area, the need to coordinate closely with landfill and RNG operations during work hours, and the requirement to maintain clean and safe work zones. Effective communication and coordination with site staff is essential. Bidders are encouraged to thoroughly review site conditions and propose solutions that align with project goals and remain within the defined scope and specifications.
