As long as the bid evaluation room can accommodate the bid evaluation committee (negotiation team, inquiry team), supervisors, impartial personnel and agency staff, the requirements are not great. As for the bid opening room, it will definitely be bigger, because the bid opening site generally needs public quotation, and basically all participants will be present, including suppliers (bidding enterprises). Of course, the bid opening room and the bid evaluation room should also have electronic monitoring equipment, and these laws also require it.
