Where to Find Construction Bids and Upcoming Projects in Seattle (2026)
Construction work in Seattle is posted in three places. Public owners advertise on the City of Seattle's Purchasing and Contracting Services, on WEBS, Washington's Electronic Business Solution, and federally on SAM.gov. General contractors invite subcontractors through BuildingConnected and PlanHub, and ConstructConnect and Dodge sell data on published commercial bids. Private work that is never publicly bid appears first as a building permit, which is where Builtie finds it and attaches the decision maker.
The same four steps, whether the buyer is a builder, a designer, an owner or a company you want to acquire.

The private work that never reaches a bid board
Most private work in Seattle, including renovations, custom homes, small commercial fit-outs and the trade packages under a general contractor, is awarded by invitation. The first public sign of it is a building permit. On September 23, 2026, 767 projects in the City of Seattle were still inside the electrical award window and 705 inside the drywall window.
Seattle's feed rarely names the builder: 1.4% of new-build permits carry one. Builtie resolves the company behind a Seattle project from other records, and does not publish a Seattle builder count because it would describe the feed rather than the market.
Which source to check first
| If you are | Check first |
|---|---|
| A trade subcontractor bidding commercial work | BuildingConnected and PlanHub invitations, then Builtie to reach GCs before they invite |
| A general contractor bidding public work | The City of Seattle's Purchasing and Contracting Services and the state portals |
| A trade selling private residential or small commercial work | Permits via Builtie |
| Looking for construction jobs, not contracts | Job boards such as Indeed and LinkedIn Jobs; this page is about contracts |
Plans
Builtie's Starter plan is $79 per seat per month (CAD) for 20 projects; Growth is $99 for 50 projects and adds the LinkedIn and email outreach you run yourself. Opening a project spends one credit, and the decision makers, emails, phones and AI call script inside it are included. Your monthly credits reset at each renewal, and extra credit packs are valid for 30 days. The free trial runs 7 days with 10 projects. Custom, where Builtie's team runs the outreach for you, starts from CAD $1,500 a month on top of a Growth seat.
Builtie's deepest coverage is in the Greater Toronto Area, where it started; depth in any city depends on what that municipality publishes. Ask for live sample projects in your own service area before you buy.
Frequently asked questions
Where can I find construction bids in Seattle?
Public work: the City of Seattle's Purchasing and Contracting Services; WEBS, Washington's Electronic Business Solution; federal work on SAM.gov. Private commercial bids: BuildingConnected and PlanHub invitations and ConstructConnect or Dodge data. Private work that is never bid shows up first as a building permit, which Builtie tracks.
Are there free construction bid sites for Seattle?
Yes. The public portals are free or cheap to search, and BuildingConnected is free for subcontractors receiving invitations.
Why don't private Seattle projects appear on bid sites?
Most private work is awarded by invitation: a developer picks a general contractor, and the GC invites trades it already knows. The project appears as a permit long before any invitation.
Does Builtie list public tenders in Seattle?
No. Builtie starts from permits and planning records and focuses on private projects and the people who award them. Plans start at $79 per seat per month with a 7-day free trial.
