Based on GB / T 51269—2017 Standards for classification and coding of building informationmodel, in response to the BIM implementation and intelligent construction management requirementsthroughout the entire process,which the project is Beijing City Sub Central Station IntegratedTransportation Hub, from the perspective of BIM model application and project business management,combined with the classification methods and creation characteristics of model components in BIMsoftware, the classification and coding design of the BIM model is carried out, as well as the developmentof automatic coding tools, and the application of component coding in the intelligent construction processis explored. A classification and coding structure based on model components is established, theclassification of model information in the national standard is expanded and refined to make it moresuitable for the actual project. The model coding design is completed, achieving automatic coding,review, and classification expansion of model components. The application scheme of model coding isexplored, through coding, the integration and sharing of engineering information throughout the entireprocess are realized. Combined with the business management mode of the intelligent constructionplatform, the application of model coding in intelligent construction is explored to empower theadvancement of project intelligent construction.
