Abstract: With the development of new technology, project management through information technology has become a new trend in project management. Beijing Fengtai Railway Station reconstruction and expansion project is a national key project. In the process of project construction, BIM Technology is applied to the project management of steel structure engineering. Through the BIM design in the steel structure project key node display application, project design, production, construction and other important data sharing and information management application, achieve the project management and control key content of visualized and fine management. At the same time, BIM Technology and BIM+GIS technology are applied in project schedule management, project management, and quality management to improve the scientific management level of steel structure engineering by realizing the traceability and maintainability of steel structure components.
