Contract Awarded on Basis of On-the-Spot Verification by Contractor

A determination was requested as to whether a contracting officer was on constructive notice of the probability of a mistake in a bid despite on-the-spot verification by the contractor. The bidder must bear the responsibility for a mistake in the bid unless the contracting officer is on constructive notice of the possibility of error. The contract should not have been awarded on the basis of on-the-spot verification, and the contracting officer should have sought further verification.
