[Protest of Army Corps of Engineers Purchase Order for Air Conditioning Equipment]

A firm protested the Army Corps of Engineers' issuance of a purchase order for air conditioning equipment, contending that the Army improperly permitted several bidders to clarify and revise bid submissions after the bid opening date. GAO held that the protester was not prejudiced by the Corp's acceptance of modified bids after the bid opening, since its own bid submission establishing its technical acceptability was also received by the Corps after the due date. Accordingly, the protest was denied.
