Spring is here, and in Washington State that means one thing for subcontractors: bidding season is heating up. Public works projects are going out to bid, general contractors are soliciting proposals, and the competition for contracts is fierce. If you’ve been losing bids because you couldn’t produce a bid bond fast enough — or you’re not entirely sure what a bid bond even requires — you’re not alone. Many subcontractors in Washington hit this wall every March when the construction pipeline opens back up. The good news is that understanding bid bonds is simpler than it sounds, and getting one doesn’t have to slow you down.
What Is a Bid Bond and Why Do Subcontractors Need One in Washington?
A bid bond is a type of surety bond that guarantees you’ll follow through on your bid if you’re awarded a contract. In plain terms, it tells the project owner or general contractor that you’re financially serious about your proposal. If you win the bid but then back out or fail to provide the required performance and payment bonds, the bid bond protects the obligee — the party requiring the bond — from the financial harm caused by having to re-bid the project or accept a higher-priced offer.
For subcontractors working in Washington, bid bonds are commonly required in the following scenarios:
- Bidding on public works projects funded by state, county, or municipal agencies
- Submitting proposals to general contractors who require bonding from their subcontractor pool
- Bidding on federally funded construction projects that follow the Miller Act or Washington’s Little Miller Act requirements
- Projects with contract values that exceed certain thresholds set by the hiring authority
Washington’s Little Miller Act — codified under RCW 39.08 — requires performance and payment bonds on public works contracts over $35,000. While the Little Miller Act specifically governs performance and payment bonds, bid bonds are often required as a prerequisite to the bidding process itself, signaling that a contractor or subcontractor can secure the downstream bonding if selected.
How Bid Bond Amounts Are Typically Calculated in Washington
Bid bond amounts in Washington are not set by a single statewide standard. Instead, they vary based on the project type, the contracting authority, and the total bid amount. That said, the most common bid bond requirement you’ll encounter is 5% of the total bid amount, though some public agencies and general contractors require 10%.
Here’s how that breaks down in practice:
- If you’re bidding on a $200,000 mechanical subcontract, a 5% bid bond means coverage of $10,000
- On a $500,000 electrical subcontract, a 10% requirement means you’d need a $50,000 bid bond
- For smaller bids under $35,000, bid bonds may still be requested even though the Little Miller Act threshold hasn’t been reached
It’s critical to read the bid invitation documents carefully. Washington State Department of Transportation (WSDOT) projects, for example, often have specific bonding instructions embedded in their contract specifications. King County, Spokane County, and Seattle public works departments may each have their own formatting and submission requirements for bid bonds as well.
The bid bond itself is typically a standard form — sometimes the AIA A310 form or a surety-company-specific form — and it must be signed by both you as the principal and by your surety company. Statement Bonds is powered by Merchants Bonding Company, an A-rated surety with over 90 years of experience, and their bid bond forms are widely accepted across Washington.
The Bid Bond Process for Washington Subcontractors: What to Expect
One of the biggest misconceptions subcontractors have about bid bonds is that they take weeks to obtain. In most cases, especially for subcontractors with clean credit and a solid work history, the process is much faster — sometimes same-day.
Here’s what the typical bid bond process looks like:
- Application: You’ll provide basic information including your business name, license number, the project details, and the bid amount
- Underwriting review: The surety will look at your credit history, business financials if the bond amount is significant, and your bonding history
- Approval and issuance: For smaller bid bonds, approval can happen within hours; larger or more complex bids may require a day or two
- Delivery: Your executed bid bond is delivered digitally or by mail, ready for submission with your bid package
Washington subcontractors should also be aware that the bid bond is not the same as your contractor license bond. The Washington State Department of Labor and Industries (L&I) requires all registered contractors to carry a license bond — $12,000 for general contractors and $6,000 for specialty contractors — but that’s a separate requirement from the bid bond tied to a specific project. Don’t confuse the two.
Spring Bidding Tips for Washington Subcontractors
March through June is prime bidding season across Washington, from Puget Sound infrastructure work to road construction projects in Eastern Washington. Here are a few practical tips to set yourself up for success this spring:
- Get pre-qualified with a surety early. Establishing a relationship with a surety agent before you need a bond means faster turnaround when a deadline is tight.
- Keep your financials current. If you’re pursuing larger contracts, having updated financial statements ready speeds up underwriting significantly.
- Read every bid package carefully. Bond percentage requirements, acceptable surety forms, and submission formats vary by agency. A bond that doesn’t match the specs can disqualify your bid.
- Don’t wait until the last minute. Bid deadlines are firm. Waiting until 24 hours before a bid is due to request a bond is a risk you don’t need to take.
- Understand your obligations. If you’re awarded the contract and back out, the surety can make a claim against you for the difference in cost to the project owner. Bid bonds are a serious commitment.
Washington subcontractors who treat bid bonds as a standard part of their business toolkit — rather than a last-minute obstacle — consistently win more work and build stronger relationships with general contractors and public agencies alike.
