Escanaba Area Public Schools in Delta County, Michigan, is seeking bids for a Unit Ventilators Replacement Project at the Upper Elementary School located at 1500 Ludington Street. The procurement involves a comprehensive mechanical system upgrade, specifically replacing three existing unit ventilators with new systems, including the installation of Direct Digital Controls (DDC) and potential future Building Automation System (BAS) compatibility. Contractors must provide a lump sum (fixed price) bid, with bids due on Monday, July 14, 2025, at 2:00 P.M. (E.S.T.). A mandatory pre-bid meeting for Prime Contractors will be held by appointment on Tuesday, July 8, 2025, and Wednesday, July 9, 2025, requiring contractors to contact Scott Peterson to schedule a site visit. The project has a desired completion date of Tuesday, August 26, 2025 (end of 2025 School Summer Break), with an alternative on-site work timeline potentially beginning on Monday, December 22, 2025. Bidders are required to submit a bid security deposit of 5 percent of the total bid amount, either through a Bid Bond or certified check, and complete a Familial Disclosure Affidavit and Iran Economic Sanctions Act compliance form.

The contract will be awarded to the most responsive and responsible bidder, with the Owner reserving the right to accept or reject any or all bids. Bidders must provide comprehensive documentation, including information about subcontractors and unit ventilator manufacturers. The project involves transitioning to R-454B refrigerant and requires careful integration with existing infrastructure, including electrical connections and refrigerant monitoring systems. The project is designed under the 2021 Michigan Building Code and Mechanical Code, covering an estimated building area of 120,010 square feet. While no specific set-aside designations for disadvantaged enterprises are mentioned, contractors will need to verify existing conditions, provide necessary sheet metal modifications, and ensure complete integration of new unit ventilators. Hard copies of project specifications can be purchased from the Engineer's office for $50.00, with additional mailing costs, and electronic PDF copies on CD are available for $25.00. The project is being engineered by Dynamic Design Group, Inc., and involves a comprehensive mechanical system upgrade with careful attention to existing infrastructure and future technological compatibility.
