A recent GAO decision should serve to caution offerors to be careful what they include with their proposals. Any information that contradicts the proposal or otherwise does not conform to the terms of the solicitation could result in disqualification.
In Independent Systems, Inc., B-413246 (Comp. Gen. Sept. 15, 2016), GAO held that the agency could reasonably disqualify an offeror based on extraneous information the offeror included with the intent of providing the agency with more information, but not changing the terms of the offer.
Picture this scenario: the government hires your company to do a job; you assign one of your best employees to lead the effort. He or she does such a good job that the government hires your employee away. The government then drags its feet on approving your proposed replacement and refuses to pay you for the time when the position was not staffed–even though the contract was fixed-price.
The scenario is exactly what happened to a company called Financial & Realty Services (FRS), and according to the Civilian Board of Contract Appeals, FRS wasn’t entitled to its entire fixed-price contract amount.
