48 CFR § 5.405 - Exchange of acquisition information.
(a) When the same item or class of items is being acquired by more than one agency, or by more than one contracting activity within an agency, the exchange and coordination of pertinent information, particularly cost and pricing data, between these agencies or contracting activities is necessary to promote uniformity of treatment of major issues and the resolution of particularly difficult or controversial issues. The exchange and coordination of information is particularly beneficial during the period of acquisition planning, presolicitation, evaluation, and pre-award survey.
(b) When substantial acquisitions of major items are involved or when the contracting activity deems it desirable, the contracting activity shall request appropriate information (on both the end item and on major subcontracted components) from other agencies or contracting activities responsible for acquiring similar items. Each agency or contracting activity receiving such a request shall furnish the information requested. The contracting officer, early in a negotiation of a contract, or in connection with the review of a subcontract, shall request the contractor to furnish information as to the contractor's or subcontractor's previous Government contracts and subcontracts for the same or similar end items and major subcontractor components.
