The State of Michigan Department of Technology, Management and Budget is soliciting sealed bids for HVAC system replacement at the Mackinac Island Heritage Center under contract 751/26109.AGY, with bids due July 1, 2026. A 10% pricing preference applies to service-disabled veteran-owned businesses meeting Michigan's SDVOB criteria; no federal CVE or SBA VetCert certifications are recognized — claimants must submit proof of service-connected disability (DD214, VA Rating Decision Letter, or NVBDC certification) and proof of 51% or greater ownership by one or more disabled veterans.

The scope encompasses complete removal of existing HVAC equipment, installation of new high-efficiency systems, ductwork modifications, controls installation, and all mechanical work to achieve current code compliance. Specifications establish standards for equipment efficiency ratings, noise levels, refrigerant performance, and warranty requirements. Contractors must demonstrate experience with similar institutional HVAC replacement projects and comply with prevailing wage requirements applicable to state-funded construction in Michigan.

Bidders submit pricing on a lump-sum basis. Bids will be publicly opened and read aloud. The contract will be awarded to the lowest responsive and responsible bidder. The project is funded through state appropriations to DTMB for capital improvements and facility maintenance. A pre-bid site visit and bidders' conference are scheduled to allow inspection of the facility and review of specifications; specific dates and times are referenced in related solicitation documents. Supporting documentation includes the 50K Spec (Rev04-26)v2.pdf, Heritage Center Blueprints.pdf, and technical diagrams (HVAC 1–4 image files).
