Design/Build for Parks Administration Building HVAC Repair and Upgrade Project

Washtenaw County Parks & Recreation Commission is requesting design-build proposals for replacement of the HVAC system serving the Parks Administration Building at 2230 Platt Road, Ann Arbor, Michigan, with proposals due August 28, 2026, and an optional pre-bid meeting on July 31, 2026.

A local-vendor preference applies: 5% discount for Washtenaw County–based companies and 3% for Michigan-based companies on qualifying bids. Bidders must submit proof of local-vendor certification if claiming the preference.

The scope encompasses complete design, engineering, equipment procurement, labor, materials, permitting, installation, system testing, commissioning, and documentation for replacement of an aging system consisting of three independent cooling zones with basement-mounted air handling units, three exterior condensers, and a separate hydronic baseboard heating system. Project completion is targeted for December 2026. The initial contract term is one year with an option to renew for an additional one year pending agreement by both parties.

Proposals must include lump-sum pricing for the entire project scope. Evaluation uses a weighted scoring matrix: energy efficiency and life-cycle operating costs (20%), proposed system design and technical approach (18%), bid-package quality and project understanding (12%), equipment cost and local serviceability (12%), humidity control and indoor environmental performance (10%), vendor qualifications and experience (10%), total project cost (8%), controls and system integration (5%), and project schedule and operational disruption (2%).

Bidders must submit three references, proof of qualifications, proof of insurance compliance, and local-vendor certification if applicable. All proposals become county property subject to the Michigan Freedom of Information Act. No payments are made until current certificates of insurance are received and approved by the County Administrator. Sealed electronic proposals are submitted through the county's Open Bids website.
