Bid Is Rejected Which Does Not Contain Acknowledgment of Amendment to IFB

A corporation's bid was rejected as nonresponsive because the bid did not contain an acknowledgment of an amendment to the invitation for bids. The protester asserted that the amendment had a negligible effect on the price and should have been waived as a minor deviation. Rejection of the bid was proper since the estimated value of the amendment constituted a 13.34 percent difference between the two low bids, and since the testing requirement in the amendment was clearly related to government quality assurance needs.
