The project witness personnel can view the bid evaluation status in real time in the office and monitoring room, and witness the control and control of the bid evaluation process。Pay close attention to the key links, witness the initiative and timely disposal of personnel in key stage nodes such as project bid opening, expert entry, abnormal bid evaluation, and the end of bid evaluation, so as to ensure smooth business and legal compliance in the process of bid evaluation。
