Surety protection for construction bids, project owners & contract commitments.
A bid bond is a type of surety bond commonly requested when contractors submit proposals for public works and certain private construction projects. It helps give the project owner assurance that the bidder intends to honor its bid and, if selected, enter into the contract and furnish required follow-on bonds.

A low bid does not always mean a contractor can perform the work. Owners use bid security to discourage unsupported proposals and reduce the financial consequences if a winning bidder refuses to sign the contract or provide the required performance and payment bonds. The bond is a three-party obligation involving the contractor (principal), project owner (obligee), and surety.
A bid bond typically applies during the bidding and contract-award process, not throughout construction. If the contractor is awarded the job and fulfills the bidding obligations, the bond’s purpose is generally complete. If the contractor defaults on those obligations, the surety’s exposure is determined by the bond form and applicable requirements.
The required bond amount may be stated as a percentage of the bid or as another specified amount. Public procurement rules, bid documents, and private owner requirements can differ. Contractors should review the exact bid package rather than assume a standard percentage applies.
Sureties may review financial statements, working capital, experience, credit, prior project performance, backlog, and the size and type of the proposed work. A contractor’s ability to obtain a bid bond may also depend on its capacity to obtain the performance and payment bonds that follow.
A bid bond addresses obligations associated with bidding and contract award. A performance bond generally addresses contractual completion obligations, while a payment bond generally protects certain qualifying subcontractors and suppliers against nonpayment. These are distinct instruments.
Before bidding, contractors can assemble the solicitation, bid amount, project description, anticipated start date, financial information, and any required bond form. Early review can help identify surety questions before a bid deadline.
A contractor should examine the invitation to bid, the required bid bond form, the amount of bid security, and the period during which the bid must remain open. Some solicitations prescribe an exact form or require a power of attorney from the surety. A bond that does not conform to the solicitation may be rejected even when the contractor otherwise qualifies. Submission methods and deadlines are equally important, especially when an electronic procurement portal is used.
For an established bonding relationship, a surety may be able to issue bid bonds within an approved program. For a new relationship or an unusually large bid, it may request recent financial statements, a work-in-progress schedule, bank information, resumes of key personnel, and a description of similar completed projects. The surety may also review the contract duration, liquidated damages, and whether the project is substantially larger than the contractor’s previous work.
Before submitting a bonded bid, contractors should confirm that the surety is comfortable considering the performance and payment bonds that will be needed if the bid is successful. A bid bond is not a promise that the later contract bonds will be issued regardless of changed circumstances. Material changes to the scope, contract terms, bid amount, or contractor finances may require another underwriting review.
Before the bid deadline, confirm the exact obligee name, bid security amount, form, submission method, and whether the surety must appear on an approved list. If the bid includes alternates or allowances, ask how they affect the required bond amount. Keeping these details together can prevent avoidable last-minute revisions.

No. A bid bond supports the bidder’s obligations during award, while a performance bond relates to the contractor’s performance after the contract is executed.
The required penal sum is determined by the bid documents or applicable procurement rules. Some sureties issue qualifying bid bonds without a separate premium when subsequent contract bonds are anticipated.
Possibly. Sureties assess experience, finances, project size, and other underwriting factors. Newer contractors may face different requirements or capacity limits.
The owner may make a claim under the bid bond if the contractor fails to meet covered bidding obligations. The outcome depends on the bond language and applicable law.
