Section 124.510 - What limitations on subcontracting apply to an 8(a) contract?(a) To assist the business development of Participants in the 8(a) BD program, there are limitations on the percentage of an 8(a) contract award amount that may be spent on subcontractors. The prime contractor recipient of an 8(a) contract must comply with the limitations on subcontracting at § 125.6 of this chapter.(b) Indefinite delivery and indefinite quantity contracts. In order to ensure that the required limitations on subcontracting requirements on an indefinite delivery or indefinite quantity 8(a) award are met by the Participant, the Participant cannot subcontract more than the required percentage to subcontractors that are not similarly situated entities for each performance period of the contract (i.e., during the base term and then during each option period thereafter). However, the contracting officer, in his or her discretion, may require the Participant to meet the applicable limitation on subcontracting or comply with the nonmanufacturer rule for each order. (1) This includes Multiple Award Contracts that were set-aside or partially set-aside for 8(a) BD Participants.(2) For orders that are set aside for eligible 8(a) Participants under full and open contracts or reserves, the Participant must meet the applicable limitation on subcontracting requirement and comply with the nonmanufacturer rule, if applicable, for each order. 81 FR 34260 , May 31, 2016
