Past Performance Reference for Similar Services Does Not Automatically Warrant Substantial Confidence Rating; GAO B-415938.2, C2G Ltd. Company

Protest challenging the agency’s past performance evaluation is denied, where the agency reasonably concluded that the protester’s past performance references were only partially similar in scope, magnitude, and complexity to the requirement, and therefore warranted only a satisfactory confidence rating, and where the agency reasonably evaluated the past performance references of the awardee’s proposed subcontractor, because it would perform a critical aspect of the requirement.
