FAR 16.503 Requirements contracts.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section describes requirements contracts, where one contractor fills all of a designated Government activity's actual needs for supplies or services during a set period, with orders scheduled as they arise. It matters because the Government states an estimated total quantity that is not a promise of actual orders, and the contract should state maximum limits on both sides if feasible. Special rules apply to large single-source awards and to advisory and assistance services.

Applies to: Contracting officers and contractors using requirements contracts

What it requires

  • The contracting officer shall state a realistic estimated total quantity in the solicitation and resulting contract.
  • The contract shall state, if feasible, the maximum limit of the contractor's obligation to deliver and the Government's obligation to order.
  • For repair work on Government property, the contracting officer shall specify in the Schedule that failure to furnish items in estimated or maximum amounts will not entitle the contractor to an equitable price adjustment.
  • For advisory and assistance services over three years and $20 million, a written determination of uniqueness or specialization is required before issuing a solicitation, unless the services are necessarily incident to and not a significant component of the contract.

The text

(a) Description. A requirements contract provides for filling all actual purchase requirements of designated Government activities for supplies or services during a specified contract period (from one contractor), with deliveries or performance to be scheduled by placing orders with the contractor.

(1) For the information of offerors and contractors, the contracting officer shall state a realistic estimated total quantity in the solicitation and resulting contract. This estimate is not a representation to an offeror or contractor that the estimated quantity will be required or ordered, or that conditions affecting requirements will be stable or normal. The contracting officer may obtain the estimate from records of previous requirements and consumption, or by other means, and should base the estimate on the most current information available.

(2) The contract shall state, if feasible, the maximum limit of the contractor's obligation to deliver and the Government's obligation to order. The contract may also specify maximum or minimum quantities that the Government may order under each individual order and the maximum that it may order during a specified period of time.

(b) Application. (1) A requirements contract may be appropriate for acquiring any supplies or services when the Government anticipates recurring requirements but cannot predetermine the precise quantities of supplies or services that designated Government activities will need during a definite period.

(2) No requirements contract in an amount estimated to exceed $150 million (including all options) may be awarded to a single source unless a determination is executed in accordance with 16.504(c)(1)(ii)(D).

(c) Government property furnished for repair. When a requirements contract is used to acquire work (e.g., repair, modification, or overhaul) on existing items of Government property, the contracting officer shall specify in the Schedule that failure of the Government to furnish such items in the amounts or quantities described in the Schedule as estimated or maximum will not entitle the contractor to any equitable adjustment in price under the Government Property clause of the contract.

(d) Limitations on use of requirements contracts for advisory and assistance services. (1) Except as provided in paragraph (d)(2) of this section, no solicitation for a requirements contract for advisory and assistance services in excess of three years and $20 million (including all options) may be issued unless the contracting officer or other official designated by the head of the agency determines in writing that the services required are so unique or highly specialized that it is not practicable to make multiple awards using the procedures in 16.504.

(2) The limitation in paragraph (d)(1) of this section is not applicable to an acquisition of supplies or services that includes the acquisition of advisory and assistance services, if the contracting officer or other official designated by the head of the agency determines that the advisory and assistance services are necessarily incident to, and not a significant component of, the contract.
