Bid Bond: What It Is, How It Works, Vs. Performance Bond

A bid bond is a type of surety bond that contractors submit alongside their bid when competing for a construction or procurement project. It acts as a financial guarantee to the project owner (often referred to as the obligee) that the contractor’s bid is serious, accurate, and binding. Essentially, a bid bond assures the owner that if the contractor is awarded the project, they will enter into the contract at the proposed price and provide any required performance or payment bonds.

Bid bonds are typically required in public sector projects, such as government contracts, or in large private projects where the stakes are high. They protect the project owner from the risk of contractors submitting frivolous or unrealistic bids, only to back out after being selected. By requiring a bid bond, owners can filter out unqualified or unreliable bidders, ensuring a smoother bidding process.

Key Parties Involved in a Bid Bond

A bid bond involves three primary parties:

Principal: The contractor or bidder who purchases the bond and submits it with their bid.
Obligee: The project owner or entity requesting the bond, such as a government agency or private developer.
Surety: The bonding company or insurer that issues the bond and guarantees the principal’s obligations.

The surety company evaluates the contractor’s financial stability, experience, and capacity to perform the project before issuing the bond. If the contractor fails to honor their bid, the surety may be required to compensate the obligee, up to the bond’s penal sum (the bond’s coverage amount).

How Does a Bid Bond Work?

The bid bond process begins when a project owner issues a request for proposals (RFP) or an invitation to bid (ITB). The bidding documents typically specify whether a bid bond is required and, if so, the bond amount, which is usually a percentage of the bid value (e.g., 5% to 10%).

Step-by-Step Process

Bid Preparation: Contractors prepare their bids, calculating costs for labor, materials, equipment, and other expenses. Alongside the bid, they obtain a bid bond from a surety company.
Bond Submission: The contractor submits the bid bond with their proposal. The bond serves as a pledge that the bid is legitimate and that the contractor intends to follow through if selected.
Bid Evaluation: The project owner reviews all bids, considering factors like price, qualifications, and compliance with requirements. The bid bond ensures that bidders are committed to their proposals.
Contract Award: If the contractor’s bid is selected, they are expected to sign the contract and provide any additional bonds (e.g., performance or payment bonds) as stipulated. The bid bond remains in effect until this step is completed.
Bond Release: Once the contract is signed and any required bonds are furnished, the bid bond is released, and its obligations are fulfilled. If the contractor fails to proceed, the obligee can make a claim on the bond.

Consequences of Default

If the winning contractor refuses to sign the contract or fails to provide the necessary bonds, they are considered in default. In such cases, the obligee can claim compensation from the bid bond. The amount paid is typically limited to the difference between the defaulting contractor’s bid and the next lowest bid, up to the bond’s penal sum. For example:

Contractor A submits a bid of $1 million with a 10% bid bond ($100,000).
Contractor A wins but refuses to sign the contract.
The next lowest bid is $1.2 million.
The obligee can claim up to $100,000 (the bond amount) to cover the $200,000 difference, though only $100,000 is recoverable due to the bond’s limit.

The surety may then seek reimbursement from the contractor for any payments made, as bid bonds are not insurance but rather a form of credit.

Cost of a Bid Bond

The cost of a bid bond is typically low, ranging from 1% to 3% of the bond amount, depending on the contractor’s creditworthiness and the surety’s assessment. For example, a $50,000 bid bond might cost the contractor $500 to $1,500. Some sureties offer bid bonds at no upfront cost, with fees deferred until the contractor is awarded the project and secures additional bonds.

Why Are Bid Bonds Important?

Bid bonds serve several critical purposes in the bidding process:

Ensuring Serious Bids: They discourage contractors from submitting lowball or speculative bids without the intent or ability to follow through.
Protecting the Obligee: Bid bonds safeguard project owners from financial losses if a contractor defaults after winning the bid.
Leveling the Playing Field: By requiring bonds, owners ensure that only financially stable and capable contractors participate, fostering fair competition.
Streamlining Project Start: Bid bonds reduce delays by ensuring the selected contractor proceeds promptly, minimizing disruptions to project timelines.

In essence, bid bonds create a layer of accountability that benefits both project owners and reputable contractors.

What Is a Performance Bond?

While a bid bond secures the bidding phase, a performance bond comes into play after the contract is awarded. A performance bond is another type of surety bond that guarantees the contractor will complete the project according to the contract’s terms, specifications, and timeline. If the contractor fails to perform—due to bankruptcy, poor workmanship, or abandonment—the performance bond ensures the obligee is compensated for losses or the project is completed by another contractor.

Like bid bonds, performance bonds involve a principal (contractor), obligee (project owner), and surety (bonding company). They are typically required for public projects and large private contracts, often covering 100% of the contract value.

How a Performance Bond Works

Contract Signing: After winning the bid, the contractor signs the contract and provides a performance bond as a condition of starting work.
Project Execution: The contractor begins work, adhering to the contract’s scope, quality standards, and deadlines.
Monitoring: The obligee oversees the project to ensure compliance. If issues arise (e.g., delays, defective work), they may notify the surety.
Default and Claims: If the contractor defaults, the obligee can file a claim on the performance bond. The surety investigates and may:
- Arrange for the contractor to correct the issue.
- Hire a replacement contractor to complete the work.
- Pay the obligee up to the bond’s penal sum to cover losses.
Completion: Once the project is successfully completed, the performance bond is released.

Cost of a Performance Bond

Performance bonds are more expensive than bid bonds due to their higher risk and longer duration. Premiums typically range from 1% to 3% of the contract value, depending on the contractor’s financial strength and project complexity. For a $5 million project, the bond might cost $50,000 to $150,000.

Bid Bond vs. Performance Bond: Key Differences

While bid bonds and performance bonds are both surety bonds used in construction and procurement, they serve distinct purposes. Below is a detailed comparison:

Aspect	Bid Bond	Performance Bond
Purpose	Ensures the contractor honors their bid and signs the contract if selected.	Guarantees the contractor completes the project per contract terms.
Timing	Required during the bidding phase, before the contract is awarded.	Required after the contract is signed, before work begins.
Coverage	Covers losses if the contractor fails to sign the contract or provide bonds.	Covers losses if the contractor fails to complete the project properly.
Amount	Typically 5% to 10% of the bid amount.	Usually 100% of the contract value.
Duration	Valid until the contract is signed or the bid is rejected.	Valid for the entire project duration, until completion and acceptance.
Cost	Lower cost (1%–3% of bond amount, often minimal or deferred).	Higher cost (1%–3% of contract value).
Risk	Lower risk, as it only covers the bidding phase.	Higher risk, as it covers the entire project execution.
Claim Scenario	Triggered if the contractor refuses to sign or provide required bonds.	Triggered if the contractor fails to deliver the project as agreed.

Complementary Roles

Bid bonds and performance bonds work together to protect the project owner throughout the project lifecycle:

The bid bond ensures the bidding process is reliable and the selected contractor is committed.
The performance bond ensures the project is completed as promised, protecting against contractor failure during execution.

For example, a government agency building a new highway might require a bid bond to secure bids from contractors. Once the contract is awarded, the winning contractor provides a performance bond to guarantee the road is built to specifications. If the contractor backs out after winning, the bid bond compensates the agency. If the contractor starts work but fails to finish, the performance bond covers the cost of completion.

Common Misconceptions

Bid Bonds Guarantee Project Completion: A bid bond only applies to the bidding phase and does not ensure the project itself is completed—that’s the role of a performance bond.
Performance Bonds Are Optional: In many public and large private projects, performance bonds are mandatory to mitigate financial risks.
Bonds Are Insurance: Surety bonds are not insurance; they are a form of credit. If the surety pays a claim, they may seek reimbursement from the contractor.
All Contractors Need Bonds: While common in public projects, bonds may not be required for smaller or private contracts, depending on the owner’s preferences.

Challenges and Considerations

For Contractors

Obtaining Bonds: Contractors with limited credit or experience may struggle to secure bonds, as sureties conduct thorough financial evaluations.
Cost Management: While bid bonds are relatively inexpensive, performance bonds can strain cash flow, especially for large projects.
Liability: Contractors remain liable for claims paid by the surety, which can impact their financial standing.

For Project Owners

Balancing Requirements: Requiring bonds increases bidder accountability but may deter smaller contractors, potentially reducing competition.
Claim Process: Filing a claim on a bond can be time-consuming and may delay the project if disputes arise.

Conclusion

Bid bonds and performance bonds are indispensable tools in the construction and procurement industries, fostering trust and accountability between contractors and project owners. A bid bond ensures that contractors submit serious, binding bids, protecting owners from the risks of default during the bidding phase. In contrast, a performance bond guarantees that the project is completed according to the contract, safeguarding owners against contractor failure during execution.
