Performance Bond

A performance bond is a surety instrument, required under the Miller Act for federal construction contracts above $150,000, that guarantees the contractor will complete the project in accordance with the contract's terms, schedule, and specifications, with the surety liable to complete or pay for completion if the contractor defaults.

What is a Performance Bond?

The performance bond is submitted by the contractor within ten days after receiving the contract award (FAR 28.106-1). It must be equal to 100% of the contract price and issued by a surety approved by the U.S. Treasury (listed in Circular 570). Unlike the bid bond, which protects against bidder withdrawal before contract execution, the performance bond protects the government throughout the entire construction period.

If a contractor defaults during performance (stops work, becomes insolvent, fails to meet specifications, or is terminated for cause), the government notifies the surety of the default. The surety then has several options under standard bond forms: it may complete the project using the defaulting contractor's remaining subcontractors, hire a replacement contractor to finish the work, or pay the government the cost of completion up to the bond amount (100% of contract value).

The performance bond is distinct from the payment bond, which protects subcontractors and material suppliers. Both bonds are required simultaneously under the Miller Act. Together they provide a two-layer protection system: the performance bond protects the government's interest in project completion; the payment bond protects the downstream supply chain.

Maintaining performance bond claims history is critical to a contractor's surety relationship. A surety that pays a performance bond claim on a contractor's default will almost certainly terminate the bonding relationship, and the contractor may be unable to obtain bonding from other sureties for years.

Why Performance Bonds matter for government contractors

Performance bonds are the single largest financial instrument most construction contractors ever execute. They define the ceiling of a firm's bonding capacity, the maximum aggregate dollar value of bonded work the surety will support simultaneously. Managing bonding capacity strategically is essential for growing construction firms.

Example

A contractor is awarded a $12M federal courthouse renovation contract. It must furnish a $12M performance bond within 10 days. The bond is issued by its surety. Three years into the five-year project, the contractor experiences severe cash flow problems and abandons the site. The Corps of Engineers notifies the surety of the default. The surety hires a completion contractor and pays the difference between the original contract value and the cost of completion, $1.8M, from the bond proceeds.

Frequently Asked Questions

Is the performance bond the same as general liability insurance?

No. General liability insurance covers third-party bodily injury and property damage claims. A performance bond is a surety guarantee that the contractor will fulfill its specific contractual obligations. They serve different risk management functions and are both typically required on federal construction projects.

What triggers a performance bond claim?

A performance bond claim is triggered by formal contractor default, typically a government termination for default under FAR 49.4. The government must follow proper default termination procedures before the surety's obligations are activated. An informal breakdown in performance without a formal termination is not sufficient to trigger bond payment.

Can a contractor cure a default and retain its surety relationship?

Sometimes. If the contractor remedies the default before the surety pays a claim, the surety relationship may survive. However, any performance bond payment by the surety, even partial, typically results in the surety reassessing and often terminating the bonding relationship. Prevention through proactive performance management is far preferable to default.

How does performance bond capacity affect contract bidding strategy?

A contractor's total bonded work in progress cannot exceed the surety's established aggregate capacity. A firm with $20M bonding capacity that already has $15M in bonded projects can only pursue new opportunities up to another $5M. Managing the bonding pipeline, completing projects to free up capacity, is a core strategic constraint for growing construction firms.
