Applied Research on BIM+GIS Integration Technology in Subway Project Management

With the development of urbanization, the construction of rail transit has developed rapidly. According to systematic analysis of existing research, 17 potential problems of subway project under the traditional project management mode are identified from the three aspects of cost, schedule and quality. Furthermore, with the semi-structured interview and on-site research, the identified problems could be summarized into 13 items. Aiming at solving the problems like insufficient information construction and information sharing delay in traditional project, this paper proposes a framework of information management cloud platform based on BIM+GIS integration technology: From the perspective of the project life cycle, the data generated in the planning-design-bidding-construction-operation and maintenance process are collected by software integration, and the data are fused by BIM+GIS data fusion interface. In addition, this study deeply analyzes the application of BIM+GIS integration technology in subway project management from three aspects: planning and design, virtual construction, and collaborative management. The research also specifically discuss the application of BIM+GIS technology in Shenzhen subway line to increase the informatization level of subway project construction management and develop the delicacy management with the whole life cycle.
