Interaction and Application of BIM Technology in Urban Rail Transit Design Phase

Building information modeling (BIM) is considered to be the core technology for the intelligent cities in China. At present, most construction projects only use BIM technology for installation projects in China, and few use BIM technology for urban rail transit projects. By using the most mainstream BIM software in China as the research tool, combining the BIM usage criteria in China, this research finds that the main reason why BIM technology can not be used in urban rail transit system maturely is that under the current technical conditions, it is almost impossible to complete the perfect interaction among the three-dimensional models. Lack of a more mature BIM management platform; and through comparative with the successful application of BIM cases in construction projects, technical improvements are provided to maximize the integration and sharing of all information in the design phase model, and the direction of optimization is put forward.
