Performance Bonds (USA)
Performance Bonds are a critical component of the construction and contracting industry in the United States, providing financial assurance that contractors will fulfill their contractual obligations. These bonds protect project owners, including government entities and private developers, from financial losses in the event of contractor default. Compliance with the Miller Act and other federal and state regulations is a key aspect of utilizing Performance Bonds effectively.
What is a Performance Bond?
A Performance Bond is a type of surety bond that guarantees a contractor (the principal) will complete a project according to the terms, conditions, and specifications outlined in the contract. If the contractor fails to fulfill their contractual obligations—whether due to default, insolvency, or other reasons—the surety steps in to ensure the project is completed. This may involve hiring a new contractor, providing financial compensation to the project owner, or other measures to fulfill the contract terms. The bond involves three parties:
- Principal: The contractor who is required to obtain the bond.
- Obligee: The project owner or government agency that requires the bond.
- Surety: The surety company that issues the bond and guarantees the contractor's performance.
The Miller Act and Performance Bonds
Under the Miller Act (40 U.S.C. §§ 3131–3134), contractors performing construction work on federal projects exceeding $150,000 are required to furnish Performance Bonds. This federal law ensures that the federal government and taxpayers are protected from financial loss due to contractor default. The Miller Act mandates that:
- Performance Bonds guarantee the completion of the project according to contract specifications.
- Payment Bonds ensure that subcontractors, laborers, and material suppliers are paid, preventing liens against the project.
Many states have enacted their own “Little Miller Acts,” applying similar requirements to state-funded public works projects, with varying threshold amounts and specific provisions.

Frequently Asked Questions
If the contractor fails to complete the project according to the contract terms, the project owner can make a claim against the Performance Bond. The surety company will investigate the claim, and if valid, will take one of the following actions:
- Arrange for Completion: Hire a new contractor to complete the project.
- Provide Financial Compensation: Pay the project owner the bond amount up to the penal sum to cover the costs of completion.
- Facilitate Contractor Support: Provide financial or technical assistance to the original contractor to enable project completion.
The contractor is then obligated to reimburse the surety for any costs incurred.
The cost of a Performance Bond, known as the premium, typically ranges from 0.5% to 3% of the total contract value. Factors influencing the cost include:
- Contractor’s Financial Standing: Credit score, financial statements, and net worth.
- Project Complexity and Size: Larger or more complex projects may carry higher premiums.
- Work History and Experience: A proven track record can result in lower costs.
- Surety’s Risk Assessment: The perceived risk of default influences the premium rate.
For example, for a $1 million contract, the premium could range from $5,000 to $30,000.
If the contractor defaults, the project owner can file a claim against the Performance Bond. The surety company will then:
- Investigate the Claim: Determine the validity and extent of the default.
- Fulfill Obligations: As per the bond terms, the surety may complete the project or compensate the owner for completion costs.
- Recover Costs: The contractor must reimburse the surety for all expenses incurred, including legal fees.
While not required for all projects, Performance Bonds are mandatory for:
- Federal Projects: As per the Miller Act, for contracts over $150,000.
- State and Local Public Projects: Under “Little Miller Acts,” requirements vary by state.
- Private Projects: Many private owners require bonds for large or high-risk projects to protect their investments.
A Performance Bond remains in effect for the duration of the contract until all contractual obligations are fulfilled. This includes:
- Project Completion: When the work is finished according to the contract.
- Acceptance by Owner: Formal acceptance of the completed work.
- Warranty Periods: Some bonds may cover warranty obligations for a specified period after completion.
Once issued, a Performance Bond cannot be unilaterally canceled by the contractor or surety. The bond remains active until:
- Contractual Obligations Are Met: Completion and acceptance of the project.
- Release by Obligee: The project owner releases the bond.
- Expiration: As specified in the bond terms, considering any warranty periods.
- Select a Surety Broker: Choose a reputable licensed surety broker, such as Stanhope Simpson.
- Prepare Documentation:
- Financial Records: Audited financial statements, balance sheets, and credit reports.
- Project Details: Contract documents, project plans, and specifications.
- Experience History: A resume of past projects, references, and qualifications.
- Complete the Application: Provide accurate and comprehensive information.
- Undergo Underwriting: The surety assesses financial strength, capacity, and project risks.
- Receive Approval and Pricing: Upon approval, pay the premium to obtain the bond.
The penal sum is the maximum amount the surety is obligated to pay in case of contractor default. It is usually equal to 100% of the contract value, fully protecting the project owner against losses up to that amount.
Yes, small businesses can obtain Performance Bonds. However, they may face:
- Stricter Underwriting Requirements: Detailed financial documentation and business plans may be required.
- Higher Premiums: Due to perceived higher risk.
- SBA Surety Bond Guarantee Program: The U.S. Small Business Administration offers a program that helps small businesses qualify for bonds by guaranteeing a portion of the surety’s risk.
The Performance Bond does not cover cost overruns unless they result from the contractor’s failure to comply with contract terms. If the contractor is unable to complete the project due to financial issues, the bond may be triggered. The project owner is generally responsible for changes in scope or unforeseen conditions that increase costs, unless otherwise specified in the contract.
