Mistakes in bids detected prior to bid opening may be corrected by bidder withdrawing the original bid and submitting a corrected bid to the delivery location specified in the bid documents before the bid opening. If there is not sufficient time prior to bid opening to withdraw the original bid and submit a corrected bid, the bidder or an authorized representative may correct the mistake on the face of the original bid; provided, the official opening time has not yet been reached. A corrected bid must be date stamped in upon resubmission.
