[Protest of Air Force IFB for Furnace Replacement]

A firm protested an Air Force solicitation for the replacement of furnaces, contending that its provisions were unreasonable because they could result in increased contractor costs. GAO held that: (1) the protester untimely filed its protest after bid opening; and (2) the protester's oral complaint to the contracting agency did not constitute a protest. Accordingly, the protest was dismissed.
