Key Takeaways

  • A contract bond vs performance bond comparison shows that both protect project owners, but they serve different purposes: contract bonds cover the contractor’s commitment to enter and honor a contract, while performance bonds guarantee the completion of work as agreed.
  • Surety bonds involve three parties—owner, contractor, and surety—and provide financial protection if obligations are not met.
  • Bid bonds protect owners if a contractor refuses to honor their bid, ensuring the project is awarded at a fair cost.
  • Performance bonds guarantee project completion according to contract terms and allow sureties to step in through financing, replacement, or payment remedies.
  • Payment bonds, often paired with performance bonds, protect subcontractors and suppliers to ensure they receive payment for their work.
  • Owners and contractors must carefully review bond forms (such as AIA A312) because unmodified terms can create costly risks.
  • Performance bonds carry industry-specific importance, as they promote trust, reduce disputes, and maintain financial stability across construction projects.

A contract bond vs performance bond serves different purposes. Clients often ask design professionals to help to get a contractor's services to help with construction projects, either by invitation or by a public bidding process. Owners need to know how to protect themselves in case the contractor doesn't meet the requirements for entering the contract or doesn't finish the project according to the specifications and plans that were agreed upon.

A Basic Guide to Surety Bonds

Sureties are a certain segment of the insurance industry that has their own set of rules and procedures for their role specifically. They write bonds that are agreements between three parties:

  • Project owner
  • Surety
  • Project contractor

While there are varying kinds of bonds, each one is specifically written to guarantee the obligations of certain contracts. Their purpose is to make sure the contractor will perform their duties to the owner, assuming the owner keeps all their promises to the contractor. The most common types of bonds are performance bonds, maintenance bonds, subcontractor bonds, bid bonds, payment bonds, and supply bonds.

Payment Bonds

While performance bonds guarantee that work is completed, payment bonds ensure that all subcontractors, laborers, and suppliers are paid for their services. These bonds protect against liens being filed against the property if a contractor fails to pay its vendors. Many public projects require payment bonds alongside performance bonds, providing complete financial protection for both owners and subcontractors.

Bid Bonds

Contractors who send in bids often need to give a bid bond as well. This states that the contractor will go into the agreement when it's offered and will provide the required bonding. Bid bonds can be written with a penalty that's equivalent to the contract price percentage, which is 5 percent, 10 percent, or 20 percent. It can also be written with a certain dollar penalty. The claim amount often covers the price difference between the first and second bidder.

If there's a claim, the company will look at the contract to recover its losses according to the indemnity agreement. If the owner decides to offer the contract to the selected contractor and they refuse to agree to it, the owner can make a claim against the bid bond for the price difference of the contract that's in question and how much the penalty bid bond or substitute contract costs, depending on which is less.

The majority of surety companies will file fees or rates for bid bonds, but it's not usual for a surety to demand payment for issuing a bid bond. This is especially true for customers who regularly produce bid bonds. As an example, X School District put out a request for proposals regarding their new high school building's roof. Contractors Y and Z both submit bids to work on this, and the district requires each to send in a bid bond along with their bid. These are purchased from sureties by the contractors.

Contractor Y's bid is accepted, but they think they underbid the project and decide not to go through with the contract or perform any work. In this case, the district can file a claim against the bid bond because the contractor didn't abide by their bid. This type of bond is designed to keep the owner safe in case bidders refuse to go into a contract once it's been awarded or if they withdraw their bid before the award.

Performance Bonds

Performance bonds make sure the contractor will perform their contractual obligations according to the specifications and plans. The function of this type of bond is to provide protection financially to the owner in case the contractor defaults. The bond company will take on all responsibilities if the contractor doesn't perform their obligations and will assume any contract responsibilities as part of the terms and conditions of their contract. In case there's a default, the bond company can finish the contract by giving any management, technical, or financial support that's required.

They can also find a new contractor and pay for the extra that it will cost to complete the contract, or they can give the owner payment for the bond's total amount. There's an inherent risk with construction work, so it's simple to see why project owners want a guarantee from the performance bond. This bond is looked at as credit for the contractor, and because the company isn't planning on a loss, they'll look to the contractor to recover their claim according to the indemnity agreement.

Industry Importance of Performance Bonds

Performance bonds play a crucial role in the construction industry beyond simple financial security:

  • Investor and lender confidence: They reassure financiers that projects will be completed.
  • Project continuity: They allow work to continue with minimal disruption in the event of default.
  • Fair competition: By requiring performance bonds, owners ensure only financially stable and reliable contractors can bid.
  • Risk reduction: They help prevent litigation by providing a clear remedy if a contractor fails to perform.

Legal and Practical Considerations

Owners and contractors should be cautious when reviewing bond forms. For example, the commonly used AIA A312 form requires specific language changes to protect the obligee fully. Failure to negotiate modifications can leave an owner paying more than once for the same work if the surety denies coverage.

In practice, courts strictly interpret bond language. If the performance bond includes conditions precedent (such as written notice of default), failing to follow these steps can void the owner’s rights. Contractors also face indemnity obligations to reimburse the surety if a claim is paid. Careful drafting and legal review reduce the risk of costly disputes.

Contract Bond vs Performance Bond: Key Differences

Although the terms are sometimes used interchangeably, contract bonds and performance bonds have distinct roles:

  • Contract Bond: A broad category that covers a contractor’s overall obligation to honor and execute a contract. This may include bid, performance, and payment bonds bundled together.
  • Performance Bond: A specific type of contract bond that guarantees project completion in accordance with contract terms.

In essence, all performance bonds are contract bonds, but not all contract bonds are performance bonds. Contract bonds emphasize entering into and honoring agreements, while performance bonds focus on the satisfactory execution of the work.
