What it is
A bid bond is a three-party agreement. The contractor (the principal) submits a bid, the project owner (the obligee) receives the bond, and a surety company stands behind the contractor's commitment. It is not insurance for the contractor; it is a guarantee to the owner.
In construction, the bid bond usually accompanies the bid package. If the contractor is awarded the work, the bid is expected to be honored, which often means signing the contract and providing any required follow-on bonds, such as a performance bond and payment bond.
If a winning bidder does not move forward, the owner may have a claim under the bond, subject to its terms. The contractor may then be responsible to the surety for related amounts. Terms and requirements differ by project, so the bid documents are the best place to start.
How it’s traditionally been approached
Public projects have long been the most common place to see bid bond requirements, though some private owners ask for them too. The bid documents or invitation to bid typically spell out whether a bond is required and in what form.
Contractors have traditionally worked with a surety agent or broker who submits an application to a surety company. The surety generally looks at the contractor's character, experience, financial strength, and work history before deciding whether to issue bonds.
Many contractors build these relationships over time, starting with smaller projects and growing as their records and financials develop. Others prepare financial statements and project information ahead of time so they can respond when a bid opportunity appears.
How the right surety agent may help
An independent surety agent may help you understand what a specific project requires, which forms the owner accepts, and how a bid bond connects to later performance and payment bonds. They may also explain what the surety will want to see from your business.
A first conversation is generally about your company: the type of work you do, your experience, your financial reporting, and the kinds of projects you hope to bid. You may be asked for financial statements, a work-in-progress schedule, or résumés for key staff, depending on the situation.
Good questions to ask include: What does this project's bid bond require? What information will the surety need from me? How does the bid bond relate to the final bonds? How early should I start before a bid deadline? What could affect whether a surety is willing to issue the bond? No agent can promise approval or a particular capacity.
The bigger picture
Bidding on work can be stressful, especially when deadlines are tight and paperwork feels unfamiliar. Understanding the bid bond process ahead of time may help you feel more settled and less rushed when an opportunity arises.
Clear financial records and a good working relationship with a knowledgeable professional can support peace of mind for you and your team.

Keep in mind
- This page is general education about surety bonds, not legal, financial, or insurance advice.
- Bid bond requirements, amounts, and procedures vary by state, agency, and project, so confirm details with the project owner or contracting agency.
- Confirm bonding options with a licensed surety agent or broker; approval, bond capacity, and contract awards are never guaranteed.
- Start early, since gathering financial and project information can take time before a bid deadline.

Frequently asked questions
What is a bid bond in construction?
A bid bond in construction is a surety bond submitted with a bid that assures the project owner the bidder will honor the bid if awarded the contract. It involves the contractor, the owner, and a surety company. Specific terms depend on the project and the bond form used.
Why do project owners require a bid bond construction guarantee?
Owners often require a bid bond construction guarantee to help screen for serious, qualified bidders and to have recourse if a winning bidder backs out. It may also signal that a surety has reviewed the contractor. Requirements vary by owner and project.
Who needs a bid bond?
Contractors bidding on projects whose bid documents call for a bond may need one. This is common on public work but can also appear on private projects. Check the bid documents and confirm with the owner or contracting agency.
How do I get a bid bond?
Contractors generally apply through a licensed surety agent or broker, who submits information to a surety company for review. You may be asked for financial statements and details on your experience. Whether a bond is issued is up to the surety.
Is a bid bond the same as a performance bond?
No. A bid bond supports the bidding stage, while a performance bond supports completing the work under the contract after award. A winning bidder may be asked to provide a performance bond, and often a payment bond, after the bid bond stage.
What happens if I win the bid but don't sign the contract?
The owner may be able to make a claim under the bid bond, depending on its terms and applicable rules. The contractor may then owe the surety for amounts it pays. Talk with a licensed surety agent and review your bid documents before bidding.
