Performance Bonds for Contractors Who Build What Matters
A performance bond guarantees you will finish the job. It is the single most important document project owners use to evaluate contractor reliability. Whether you are pursuing federal projects under the Miller Act, state public works, or private institutional contracts, your bonding capacity determines which projects you can win.
What Is a Performance Bond?
A performance bond is the cornerstone of construction project security. It protects the owner's investment and ensures the contractor has the financial backing to complete the work.
A Guarantee of Project Completion
A performance bond is a surety bond that guarantees the contractor will complete the construction project according to the contract documents, including plans, specifications, and timeline. If the contractor defaults, the surety steps in to either finance completion by the original contractor, hire a replacement contractor, or pay the owner the cost to complete the project, up to the bond's penal sum.
Typically 100% of Contract Value
Performance bonds are almost always written at 100% of the contract price. On a $5M highway project, the performance bond has a $5M penal sum. This gives the project owner full financial protection against contractor default. The surety's exposure is the cost to complete the remaining work minus any contract balance the owner has not yet paid.
Required by Law on Public Works
The federal Miller Act requires performance bonds on all federal construction contracts over $150,000. Every state has a Little Miller Act with similar requirements for state-funded projects. Thresholds vary: California requires bonds on public works over $25,000, while other states set higher thresholds. Many private owners, particularly institutional and commercial developers, also require performance bonds on projects over $1M.
The Three-Party Relationship
A performance bond involves three parties. The principal is the contractor who performs the work. The obligee is the project owner who is protected by the bond. The surety is the bonding company that guarantees performance. Unlike insurance, where the carrier absorbs the loss, the surety expects full reimbursement from the contractor if a claim is paid. This is why sureties underwrite contractors so carefully.
When Is a Performance Bond Required?
Performance bonds are mandatory on virtually all public works construction in the United States. Private owners and lenders increasingly require them as well. Here are the most common scenarios.
- Federal construction projects over $150,000 (Miller Act, 40 USC 3131)
- State and local public works projects (Little Miller Acts, thresholds vary by state)
- Municipal infrastructure: roads, bridges, water treatment, schools, government buildings
- Private commercial projects where the owner or lender requires bonding
- Institutional projects: hospitals, universities, religious facilities
- Residential subdivision and development projects with municipality requirements
- Renovation and tenant improvement projects over $1M for institutional owners
- Any project where the owner wants financial assurance of completion
Real-World Performance Bond Claim
School District Renovation Project
A general contractor was awarded a $4.8M elementary school renovation with a 12-month construction schedule. At month seven, with approximately 55% of the work complete, the contractor experienced cash flow failure. Subcontractors stopped receiving payments, work slowed, and the contractor eventually abandoned the project.
The school district declared the contractor in default and filed a claim against the performance bond. The surety investigated, confirmed the default, and hired a completion contractor. The remaining 45% of the work cost $2.9M to complete due to the costs of remobilization, corrective work on deficient items, and schedule compression to meet the school's opening date.
Completion Cost: $2,900,000
- • Completion contractor mobilization: $180,000
- • Remaining construction work: $2,160,000
- • Corrective work on deficient items: $290,000
- • Schedule acceleration premium: $270,000
The performance bond protected the school district from absorbing $2.9M in completion costs. The surety pursued the defaulting contractor for full reimbursement.
Performance Bond FAQ
What is a performance bond?
A performance bond is a surety bond that guarantees a contractor will complete a construction project according to the contract terms. It protects the project owner from financial loss if the contractor defaults, abandons the project, or fails to meet specifications. The surety company that issues the bond assumes responsibility for ensuring the project is completed. Performance bonds are typically set at 100% of the contract value.
How much does a performance bond cost?
Performance bond premiums typically range from 1% to 3% of the contract value. On a $1M project, expect to pay $10,000 to $30,000. The exact rate depends on your company's financial strength, credit history, experience, project type, and bonding capacity utilization. Contractors with strong financials and established surety relationships often secure rates at the lower end. Performance and payment bonds are usually quoted together as a package.
What happens when a performance bond claim is filed?
When the project owner declares the contractor in default and files a claim, the surety investigates to determine if the default is legitimate. If the claim is valid, the surety has several options: finance the original contractor to complete the work, hire a replacement contractor, negotiate a settlement with the owner, or pay the owner up to the penal sum to cover completion costs. The surety then pursues the contractor for full reimbursement under the indemnity agreement.
How long does it take to get a performance bond?
Initial surety qualification for a new bonding relationship takes 3 to 10 business days. The surety needs to review your financial statements, credit, experience, and current work in progress. Once your program is established, individual performance bonds for specific projects can be issued in 24 to 48 hours. For time-sensitive situations, some sureties can expedite the process. Having your financial documents organized and current speeds up the timeline significantly.
What do sureties look at when underwriting a performance bond?
Sureties evaluate three primary factors: character, capacity, and capital. Character includes your credit history, references, and reputation. Capacity is your technical ability and experience completing similar projects. Capital is your financial strength: working capital, net worth, bank relationships, and equipment ownership. The surety also reviews your work in progress schedule, project backlog, and the specific project you are bonding. Strong financials and a track record of successful project completion are the keys to bonding approval.
Can I get a performance bond with bad credit?
It is more difficult, but possible. Personal credit scores below 650 limit your options with standard surety markets. However, specialty surety programs exist for contractors with credit challenges. Expect higher premiums (2% to 5% of bond amount) and potentially collateral requirements. Demonstrating strong project experience, adequate working capital, and a clear explanation of past credit issues improves your chances. Some sureties weight financial capacity more heavily than credit scores.
What is the difference between a performance bond and insurance?
The fundamental difference is who bears the ultimate financial loss. With insurance, the carrier pays claims and absorbs the loss in exchange for premiums. With a surety bond, the surety pays the claim to the project owner but then seeks full reimbursement from the contractor under the indemnity agreement. A performance bond is essentially a guarantee backed by the contractor's personal and corporate assets. This is why sureties underwrite contractors' financials rather than just collecting premiums.
