This paper will introduce the entire life cycle applications of BIM in the Shenshan Station Building project. It is a big railway station and integrated transport hub project. It is a large-scale building, has an elaborate structure, many professional interfaces, and the construction environment is near the existing railway lines. In light of the common problems in railway BIM application, such as inconsistent modeling standards, lack of model detail and absence of a unified collaboration platform, a technical route was formed in the project based on four tasks: one set of standards, one group of high-precision models, one collaborative platform and multiple uses of one model. The paper introduces the standard system, the construction of architectural, structural, MEP and bridge models, and the application of BIM at different stages of design, construction and operation. MaaS platform is used to share model viewing, document management, WBS linkage, issue management, asset information transfer, etc. According to the actual application results, 188 MEP coordination and clearance problems have been discovered in the project; 56 reserved-opening and prefabricated equipment-room drawings have been produced; up to 150 complex beam-column reinforcement joints have been supported; and the BIM+GIS earthwork checking error is still less than 3%. Based on the above practices, it can be concluded that to achieve the value transfer of BIM from design to construction and operation, a unified data standard, a high-precision model and a controlled platform are needed. It is also a typical case of the digital construction of a large railway station building.
