You need one when a contractor, project owner, or public authority requires it in the contract or solicitation, especially when late or defective materials could disrupt the project.
Under FAR 28.102-1, federal construction contracts over $150,000 generally require performance and payment surety bonds. The contract may require supply bonds separately.
The federal bonding threshold doesn’t automatically mean the project needs bonding, but the contract or solicitation may include separate bonding requirements.
