Roof Replacement City of Green Bay ESG 3-22

The City of Green Bay, Wisconsin, is seeking sealed proposals for a public works improvement contract (ESG 3-22) involving a complete roof replacement at the Eastside Municipal Garage located at 1820 Mills Street. The project requires a full tear-off and installation of a new fully adhered 60 mil EPDM single-ply roof system over the office area, with specific technical requirements including isocyanurate foam core insulation and formed aluminum fascia with Kynar 500 fluoropolymer finish. Acceptable roofing manufacturers include Carlisle Tire and Rubber Company, Firestone Building Products, and Johns Manville. Bidders must submit proof of responsibility at least five calendar days prior to bid opening and be approved contractors by the roofing membrane manufacturer. A pre-bid meeting was held on June 29, 2022, at the project site, with sealed proposals due on July 12, 2022, at 2:00 p.m. in the City Clerk/Treasurer's office. All work must be completed by September 30, 2022, with liquidated damages of $500 per calendar day for missed deadlines.

The contract allows for broad participation, with no specific set-aside designations for disadvantaged enterprises mentioned. Bidders must submit a bid deposit of 5-10 percent of the bid amount and, if awarded, execute a performance bond equal to 100 percent of the total bid within ten days of contract award. The project is subject to Wisconsin prevailing wage requirements and substance abuse prevention compliance per Section 103.503 of Wisconsin Statutes. Contractors with convictions under Wisconsin Statutes Chapter 133.01 are disqualified from bidding on City projects for three years from the conviction date. An addendum to the original contract has been issued, allowing for a phased approach that permits contractors to install temporary roof provisions by September 30, 2022, with the full roof replacement to be completed in spring 2023 if material lead times are an issue. While a specific budget range is not disclosed, the project requires a 15-year no-dollar-limit manufacturer warranty and comprehensive roofing system installation.
