The attached chart supplements the guidance in Acquisition Guide Chapter 42.101, Audit Requirements for Non-Management and Operating Contracts. The chart presents the audit services requirements discussed in Acquisition Guide Chapter 42.101 in a series of tables arranged by contract type. The order of the tables follows the order used in the Subparts of FAR Part 16—TYPES OF CONTRACTS, which is: Fixed-Price, Cost-Reimbursement, Incentive, Indefinite-Delivery, Time-and-Materials, and Labor-Hour Contracts. Each table provides when the requirement arises (pre-award or post-award), how often, what the requirement is, and the source of the requirement (FAR, DEAR, or DOE Policy), including specific references.
