How to bid on these plumbing 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.
