Failure to Acknowledge Amendment to Bid Solicitation

The protester objected to the award of a contract for construction work to any other firm. The protester's low bid was rejected because of failure to neither acknowledge nor return an amendment to the solicitation. The bid was nonresponsive since the amendment containing Davis-Bacon Act wage determination was per se material and failure to acknowledge it may not be waived as a minor informality, despite the minimal impact on price.
