What is a bid bond?
- Obligee (the project developer or owner)
- Principal (the proposed contractor)
- Surety (the company issuing the bond)
Quick Takeaways
- A bid bond is a construction bond that ensures a bidder on a project honors the bid terms and follows through with the project.
- You may need a bid bond if you plan to bid on a construction job as a prime contractor or subcontractor.
- In the construction bidding process, contractors will estimate how much they predict the project will cost them to complete and submit a bid for that amount to the project owner. The project owner will typically choose the contractor with the lowest – and most affordable – bid.
Why are bid bonds required, and who needs them?
How do bid bonds work?
The Reason for Bid Bonds
The purpose of this bond is to prevent a contractor from submitting a frivolous bid (when they aren’t serious about taking the job) or lowballing a bid (just to win the project). It guarantees the project owner that the winning contractor accepts the assignment and honors all bid terms after signing the contract.The Consequences of Breaking a Contract
If a contractor breaks the contract and pulls out of the process after signing, the owner must find a new contractor (usually the next lowest bidder). The project owner can make a claim on the bond for reimbursement for the difference in cost between the lowest bid and the second-lowest bid or the bond penalty (whichever is lower). The surety company that is jointly and severally liable for the bond will cover the costs. Then the original contractor – who pulled out of the agreement – will indemnify the surety bond company.Avoiding Bond Claims
To avoid claims on your surety bond, only submit accurate and serious bids. Fulfill the terms of the agreement, and obtain a performance bond to replace your bid bond after you win a bid.- Project amount
- Experience of the contractor
- Quality of financial presentation
- The contractor’s credit and financial history
