A protest of four contract awards for architect-engineer services was denied by the Court of Federal Claims because the protester did not show it was prejudiced by the government's failure to collect performance information from the incumbent contractors or the source selection authority's improper analysis. The solicitation for A-E services to support disaster relief contemplated the award of up to four indefinite-delivery/indefinite-quantity contracts. In administering the contracts awarded under the prior solicitation, the government did not prepare past performance evaluations of the contractors, as set forth in FAR 42.1502. FAR 42.1502 requires the government to prepare, "at the time the work under the contract or order is completed," past performance evaluations "for each [A-E] services contract of $30,000 or more." This failure, which "violated explicit law," adversely affected the government's evaluation under the part performance factor and the cost-estimating subfactor in the successor procurement.
