Unit Ventilators

The state and local contract opportunity is for unit ventilator replacement at the Escanaba Area Public Schools' Upper Elementary School, located in Escanaba, Michigan, within Clinton County and Edmore Village. The procurement involves comprehensive mechanical system upgrades, specifically replacing three existing unit ventilators originally installed in 2001 with new Airedale units that are approximately 48" wide. Acceptable manufacturers include Trane, Carrier, Daikin, or approved equals, with requirements to remove existing pneumatic controls and install new direct digital control (DDC) systems compatible with future building automation. The bid is scheduled for submission by Friday, August 1, 2025, at 10:00 am, with a public bid opening at 10:15 pm at the Dynamic Design Group, Inc. (DDGi) office. Contractors must provide comprehensive documentation, including manufacturer literature, subcontractor information, and performance assurance bonds. The project has two potential completion timelines: the preferred completion is by Tuesday, August 26, 2025 (end of 2025 School Summer Break), with on-site work beginning no earlier than Wednesday, July 16, 2025, or an alternative completion date of Thursday, January 1, 2026, during the 2025 Christmas Break.

The contract opportunity does not explicitly specify set-aside designations or restrictions for disadvantaged enterprises. Contractors must submit completed Familial Disclosure and Iran Economic Sanctions Act affidavits and provide performance and payment bonds covering 100 percent of the contract price. The project will be awarded as a single prime contract, with the owner reserving the right to accept or reject any or all bids. Existing infrastructure includes a 120,010 square foot facility classified as an E (Educational) occupancy with Construction Type IIB, fully sprinkled, and requiring careful integration of new unit ventilators with existing mechanical systems. While no specific budget range is provided, contractors must verify power requirements, modify sheet metal, and ensure new equipment matches existing capacities and refrigerant requirements. Potential bidders must also include roofing subcontractor information and demonstrate capability to modify ceilings, walls, roofs, and flooring to meet or exceed existing conditions.
