The expert team believed that the submitted documents of the preliminary design (intermediate) were comprehensive. The proposed line route and the stations distribution arrangements were based on the feasibility study report and overall design, which fit Qingdao’s urban comprehensive planning, urban railway transportation network planning and the requirements of the railway transportation construction plan. Its function and orientation were clearly identified. Its main design principles and technical standards are in compliance with the urban railway transportation project construction standard and requirements of the Code for Metro Design. The metro’s line route, line laying method, stations distribution arrangements are coordinated with land-using planning; the arrangements for the transferring stations are reasonable, so are the function, scale and structure of the stations. The technical standard and configuration of the vehicle and electromechanical equipment system meet the operation function requirements. The documents have clearly responded to the suggestions raised by experts during past reviews, which were put them into practice and reached the depth requirements for developing the preliminary design documents.
