The bidder who submitted the bid with the first rank will be the subject of eligibility confirmation (hereinafter referred to as "confirmation subject"). If there are one or more bidders who submitted valid bids, the bid award decision will be immediately suspended. If there are no bidders who submitted valid bids, a re-bid will be held.
