The judges (including the owners' judges) have too much power, and the expert judges are generally composed as follows: 2 owners participate, 5 are randomly selected from the expert database, and the judges are composed of 7; If the owner participates in 3 people, 6 people are randomly selected from the professional library, and the judges are composed of 9 people.

When evaluating bids, the judges are divided into seven judges, three judges and four judges. The nine judges are divided into four and five. The technical bid and economic bid were evaluated by two groups respectively, and the owner's representative also participated in the bid evaluation of the two groups. Because experts and owners' representatives have different personal qualities, in some cases, one or two people can win the bid.
