Considering the drawbacks of inconsistent building information modeling (BIM) methods and nonstandard information in rail transit engineering, it is difficult to effectively and uniformly use BIM model data. Therefore, the Industry Foundation Classes (IFC)based BIM component standard library for rail transit engineering was studied. First, the component types, IFC expression of component information, and IFCbased extensibility mechanisms were studied according to the expression requirements of rail transit engineering components. Second, the technology framework of the BIM component standard library for rail transit engineering was proposed, including basic, technical, application, and user layers. Third, the classification and code method in the national standard was used to define the classification and code of these BIM components, and a component information template was proposed to define the component properties and their resource links. Finally, encryption and decryption methods for the BIM component model were applied to ensure the security of the BIM model data. The results showed that the proposed unified BIM component library enabled project participants to use standardized BIM component models to create a project model for rail transit engineering, ensuring the standardization of BIM models.
