Bonding Requirements

Bonding requirements in federal construction are the mandatory surety bond obligations established by the Miller Act and FAR Part 28, requiring contractors to furnish bid bonds before award and performance and payment bonds after award on construction contracts exceeding $150,000.

What are Bonding Requirements in Federal Construction?

Federal construction bonding requirements operate at three procurement stages. At the bidding stage, contractors must submit a bid bond of typically 20% of their bid price to guarantee they will execute the contract and furnish required bonds if selected. At the award stage, contractors must furnish a performance bond and a payment bond, each equal to 100% of the contract price, within 10 days of receiving the contract award.

The thresholds that trigger specific bonding requirements under FAR 28.102 are: contracts above $150,000 require all three bonds (bid, performance, payment) from Treasury-approved sureties; contracts between $30,000 and $150,000 allow alternative payment protections in lieu of formal payment bonds; contracts below $30,000 have no mandatory bonding requirement, though agencies may still require bonds at their discretion.

Design-build contracts, job order contracts (JOC), and indefinite-delivery indefinite-quantity (IDIQ) construction vehicles all have bonding requirements, though the application varies. IDIQ vehicles may require bonds at the task order level rather than at the base contract level, since the base IDIQ has no defined scope or price.

A&E (architect/engineer) contracts are service contracts, not construction contracts, and are not subject to Miller Act bonding. However, A/E firms typically carry professional liability (errors and omissions) insurance, which serves an analogous risk management function for design services.

The contracting officer has authority to require bonding on contracts below the statutory thresholds when the risk profile warrants it, and to accept alternative forms of security such as irrevocable letters of credit or tripartite escrow agreements when a Treasury-approved surety is not available or when alternative security is more appropriate.

Why Bonding Requirements matter for government contractors

Bonding requirements create a natural market segmentation in federal construction. Contractors with established surety relationships and adequate bonding capacity can compete for projects of any size within their capacity; contractors without bonding are limited to contracts below $30,000 or must pursue subcontracting opportunities under a bonded prime.

Example

A federal agency solicits bids for a $2.8M parking structure. The IFB requires a 20% bid bond from all bidders. The successful low bidder must furnish a $2.8M performance bond and a $2.8M payment bond within 10 days of award notification. The contractor's surety issues all three bonds; the contracting officer verifies surety approval on the Treasury Circular 570 list before counter-signing the contract.

Frequently Asked Questions

What happens if a contractor cannot furnish bonds after winning the bid?

If the low bidder cannot furnish required performance and payment bonds within the specified time, the award may be rescinded and the bid bond may be called. The contract may then be awarded to the next lowest responsive, responsible bidder. This outcome damages the contractor's surety relationship and may affect future bonding capacity.

Do subcontractors need their own bonds on federal construction projects?

Subcontractors on federal projects are not separately required to furnish bonds by the Miller Act, the prime contractor's payment bond covers them. However, the prime may require subcontractors to furnish their own performance and payment bonds as a condition of the subcontract, particularly on large or complex scopes.

Can bonding requirements be waived?

Statutory Miller Act requirements for contracts above $150,000 cannot be waived by the contracting officer. For contracts below the statutory thresholds, contracting officers have discretion in setting bonding requirements. Waivers of statutory bonding requirements require specific legal authority and are rarely granted.

How do bonding requirements affect subcontracting opportunities?

Subcontractors are not required to provide Miller Act bonds to the government, but the prime's payment bond protects them. Subcontractors pursuing set-aside subcontracting opportunities on bonded federal contracts can focus on technical and pricing qualifications rather than bonding capacity, making federal subcontracting more accessible than prime contracting for firms without established surety relationships.
