For Federal Supply Schedule procurements, agencies are not required to evaluate past performance references of subcontractors, unless the solicitation provides otherwise.
As one offeror recently discovered in Atlantic Systems Group, Inc., B-413901 (Jan. 9, 2017), unlike negotiated procurements, where agencies “should” evaluate the past performance of subcontractors that will perform major or critical aspects of the contract, offerors bidding under FSS solicitations should not assume that a subcontractor’s past performance will be considered.
