Performance Bond
A surety bond guaranteeing a contractor will complete a project as specified.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Performance Bond?
A performance bond is a type of surety bond that guarantees a contractor will complete a project in accordance with the contract terms. If the contractor defaults, the surety company steps in - either by completing the project with a replacement contractor, funding the original contractor to finish, or paying the project owner the cost of completion up to the bond amount.
Performance bonds are a risk management tool for project owners. Rather than relying solely on the contractor's financial strength, the owner has a creditworthy surety company backing the obligation. For federal government contracts over $150,000, performance bonds are required by the Miller Act. Many large private projects also require them.
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Three-Party Structure
A performance bond involves three parties: the principal (the contractor who purchases the bond), the obligee (the project owner who benefits from it), and the surety (the bonding company that guarantees performance). The surety is not a co-signer - it is separately obligated to the owner if the contractor fails.Surety's Options on Default
When a contractor defaults and the owner calls the bond, the surety has several options: finance the original contractor to complete the work, find a replacement contractor, complete the work itself through its own resources, or pay the owner the cost to complete up to the bond amount. The surety chooses which option to pursue.Miller Act Requirements
On federal construction contracts over $150,000, the Miller Act (40 U.S.C. Section 3131) requires both a performance bond (for project completion) and a payment bond (for payment to subcontractors and suppliers). Many states have "Little Miller Acts" with similar requirements for state and municipal contracts.Payment Bond vs. Performance Bond
A payment bond protects subcontractors and material suppliers - ensuring they will be paid even if the general contractor defaults. A performance bond protects the project owner - ensuring the work gets done. They are separate bonds, often required together.Bond Premium and Underwriting
The contractor pays a premium - typically 0.5% to 3% of the contract value - to obtain the bond. The surety underwrites the contractor's financial strength, track record, and project experience before issuing the bond. A contractor who cannot be bonded is a significant risk signal for project owners.Real-World Example
Redstone Development contracts with BuildMax Construction for a $4M commercial build with a 100% performance bond. Eight months in, BuildMax becomes insolvent and abandons the project at 60% completion. Redstone calls the bond.
The surety must respond. It will investigate the default, assess the completion cost, and choose its course of action. If completing the project costs $1.8M, the surety can pay that amount directly to a replacement contractor or fund the completion itself. The bond covers up to $4M - the full contract value. Redstone does not need to sue BuildMax directly for the completion costs; the surety is on the hook. Redstone should also check whether a payment bond was in place to protect subcontractors who may have unpaid claims.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.
Watch Out For
Waiting too long to call the bond after default
Performance bonds have notice requirements and time limits. Delay in notifying the surety after a contractor default can prejudice your claim. Read the bond form carefully and notify the surety in writing immediately when you believe a default has occurred.Assuming the bond covers all damages
Performance bonds cover the cost of completing the work - not necessarily delay damages, lost profits, or consequential losses. Check the bond form and your underlying contract to understand exactly what is covered.Making contract changes without notifying the surety
Material changes to the underlying contract - scope changes, price increases, extended timelines - can potentially affect the surety's obligations. Many bond forms require consent of the surety for material changes. Failing to notify can give the surety a defense to bond claims.Don't let performance bond deadlines catch you off guard
Key dates tied to performance bonds - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Require performance bonds for all large construction and infrastructure contracts
For any project where contractor default would leave you with a half-finished facility and significant completion costs, a performance bond is worth the premium cost. The 0.5-3% premium is inexpensive compared to the exposure from an unfinished project.Verify the surety's financial rating before accepting the bond
A bond is only as good as the surety's ability to pay. Before accepting a performance bond, verify the surety is rated at least "A-" by AM Best or is listed on the US Treasury Department's approved surety list (Circular 570).Frequently Asked Questions
Who pays for the performance bond?
The contractor (principal) pays the surety premium. The cost is typically included in the contractor's bid price and ultimately passed through to the project owner. A bond requirement may increase the contract price by roughly 0.5-3% of the contract value.
Is a performance bond the same as insurance?
No. Insurance protects the insured party against their own losses. A performance bond protects the project owner (the obligee) against the contractor's failure to perform. If the surety pays out on a bond, it typically has the right to seek reimbursement from the defaulting contractor - unlike an insurance payout.
Can a performance bond be required in non-construction contracts?
Yes, though it is less common. Performance bonds are used in some large IT contracts, government service contracts, and commercial supply agreements where a key vendor's default would cause substantial harm. The structure and requirements are the same as construction bonds.
