A post-award protester waived its right to challenge the awardee's compliance with a solicitation term, according to the Court of Federal Claims, because the protester failed to request clarification on the term before final bids were submitted and implicitly endorsed the government's interpretation during a protest before the Government Accountability Office. The request for proposals for managed health care support services included a technical approach subfactor for referral management and permitted technical proposals to include "enhancements" that exceeded the government's minimum requirements. The protester contended the awardee proposed a referral management procedure that differed from the procedure set forth in an operations manual.
