How to bid on these HVAC jobs in Washington

1. Register firstFederal bids require an active SAM.gov registration (free) with a Unique Entity ID. Registration can take several weeks, so start before you need it. Bids from state, county or city sites link to that agency’s own portal; follow its registration and submission rules.
2. Check the notice typeA Solicitation or Combined Synopsis/Solicitation is open for offers. A Presolicitation means one is coming. A Sources Sought is market research: you reply with your capabilities, not a price.
3. Check eligibilityIf a set-aside is listed (for example Total Small Business, 8(a), HUBZone, SDVOSB or WOSB), only firms with that status can bid. Check the NAICS size standard too.
4. Read every documentOpen the official posting, download the attachments and amendments, and note any site visit or pre-bid meeting, bonding or insurance requirements. Larger federal construction jobs usually require bid, performance and payment bonds.
5. Submit on timeSubmit exactly the way the notice says (email, portal, or paper) before the deadline shown on the posting. Late offers are usually rejected.
