Bid Bond
A surety bond submitted with a contractor's bid guaranteeing they will enter into the contract and provide required performance and payment bonds if awarded the project.
What It Is
A bid bond is a pre-contract surety bond that accompanies a contractor's bid on a construction project. It guarantees two things: that the contractor's bid is submitted in good faith, and that if awarded the project, the contractor will execute the contract and provide the required performance and payment bonds.
If the winning bidder fails to enter into the contract or provide the required bonds, the surety is liable to the project owner for the difference between the defaulting bidder's price and the next acceptable bid, up to the bid bond's penal sum. The penal sum is typically 5-10% of the bid amount for public projects.
Bid bonds are standard requirements for virtually all public construction projects. They protect project owners from bid shopping, bid withdrawal, and irresponsible bidding by contractors who lack the capacity to perform.
Why It Matters for Brokers
For brokers serving construction clients, bid bonds are often the entry point to the surety relationship. A contractor who cannot obtain bid bonds cannot compete for public work. Brokers must be able to facilitate quick bid bond issuance — sometimes within hours of a bid deadline. Understanding the contractor's bonding program and maintaining current financial information with the surety is essential for timely bid bond execution.
Real-World Example
A general contractor submits a $8.5M bid on a county courthouse renovation, accompanied by a bid bond with a 10% penal sum ($850K). The contractor is the low bidder but then discovers a $400K estimating error and wants to withdraw. Under the bid bond, the surety would be liable for the difference between $8.5M and the next bidder's price of $9.1M — a $600K exposure. The contractor decides to honor the bid rather than trigger a bid bond claim.
Common Mistakes
- 1Submitting a bid bond without confirming the surety will issue the follow-on performance and payment bonds — winning a bid you can't bond is worse than not bidding.
- 2Not checking the bid bond form requirements in the bid documents, as some project owners require specific surety company qualifications like Treasury listing.
- 3Failing to account for aggregate bonding capacity when pursuing multiple bid opportunities simultaneously.
