Title 41 › Subtitle Subtitle I— Federal Procurement Policy › Chapter 39— SPECIFIC TYPES OF CONTRACTS › § 3905
You cannot use contracts that pay a fee as a percentage of the contractor’s costs. If a contract pays costs plus a fixed fee, the agency sets the estimated cost when signing and the fee limits are: 10% normally, 15% for experimental, development, or research work, and up to 6% for architect or engineer services on public works or utility projects (the 6% can include the contractor’s costs). Contractors must tell the agency ahead of time about any cost-plus-fixed-fee subcontract or any fixed-price subcontract or purchase order that is larger than the simplified acquisition threshold or more than 5% of the prime contract’s estimated cost. The agency may inspect plans and audit the books and records of the prime contractor or subcontractors on cost or cost-plus-fixed-fee contracts.
