HVAC Mechanical and Plumbing Unit Price Portwide 2026

The Port of Seattle is soliciting bids for its HVAC Mechanical and Plumbing Unit Price Portwide 2026 contract (MC-0322990), with a pre-bid meeting on November 17, 2026 and bids due December 2, 2026. The WMBE utilization goal of 4% is aspirational, while apprentice utilization of 15% of total labor hours is required under RCW 39.04.320.

Scope includes, but is not limited to, mechanical, plumbing, and HVAC work and related electrical controls, performed under individual Work Authorizations at various Port of Seattle locations in King County. Within 72 hours of a written request, the contractor must furnish cost estimates covering labor, tools, equipment, materials, and incidentals. Bid items include hourly labor rates for sheet metal, plumbing/pipe fitter, and AC/refrigeration technician work at day and night rates, plus mark-up percentages for subcontractors, materials, equipment, and permits/testing. Prevailing wage compliance applies, with intents and affidavits submitted annually for work completed in the prior twelve months.

The total contract amount is not to exceed $1.62 million, excluding Washington State sales tax, over a 365-calendar-day term from the Contract Execution Date. The Port will evaluate unit prices, bid in figures only, against estimated quantities and weights to identify the apparent low bidder. Actual work may vary substantially from those estimates without adjustment to unit prices.

Bidders must submit a 5% bid bond or bid security, the Subcontractor Work Listing (Document 00 43 70), and the WMBE Commitment Plan Form. Performance and payment bonds in the full contract amount are required before contract execution.
