In order to compare and choose in the final negotiation. In the bidding process of fine decoration projects, there are usually many potential bidders who submit their bids to the owners or developers. Among these bidders, according to the requirements and standards of the tender documents, qualified bidders are selected for preliminary evaluation, and then the final winning bidder is selected. In some cases, there will be more than one qualified bidder. At this time, the owner or developer can choose to list multiple bidders as candidates for winning the bid, so as to make a comparative choice in the final negotiation. Doing so can increase competition and help owners or developers get better prices and services. Therefore, there will be eight successful candidates for the fine decoration project because there are many qualified bidders, and the owners or developers hope to get better results in the final selection.
