Dane County is seeking bids from qualified contractors for the Dane County Courthouse District Attorney's Office Renovation, located at 215 S. Hamilton St., Madison, WI. This project involves the full buildout of new fourth-floor office space, major renovation of the vacated third-floor area including expansion of the existing mezzanine, and mechanical upgrades to the second-floor Air Handling Unit through installation of a new supply fan array. Work will be delivered under a lump sum contract. Question Deadline 01/09/2026 at 4:00 PM CT All inquiries related to this Request for Bids (RFB) must now be submitted electronically through online. Bidders are responsible for raising any questions, exceptions, or suggested changes during this period. The goal of this project is to modernize existing office space, expand capacity for DA staff operations, and upgrade building systems to support the renovated and expanded program area. Work is expected to be performed in coordination with active facility operations, occupied spaces, limited access windows, and must comply with all applicable county specifications, ordinances, or local permitting requirements. Interested vendors should have demonstrated experience in interior office renovations, multi-trade buildouts, mechanical system retrofits, and construction within occupied government facilities with the ability to manage projects of similar size and complexity. This project is part of Dane County's ongoing facility modernization efforts and addresses growing operational needs within the District Attorney's Office. The existing third-floor space requires significant renovation and reconfiguration, while the fourth-floor buildout will provide additional functional offices to support current workloads. Mechanical systems serving these floors, including the second-floor Air Handling Unit, require upgrades to ensure reliable performance and proper capacity for the expanded occupied area. Key considerations for vendors include working in an active and occupied government building, limited staging areas, the need to maintain safe and clean work zones, and close coordination with County staff to minimize operational disruptions. Contractors should anticipate strict sequencing requirements, noise-sensitive work periods, confined access points, and the need for high-quality workmanship throughout the duration of construction. The County encourages bidders to review site conditions carefully and propose approaches that align with the project goals, within the scope and specifications provided.
