As an advanced digital tool, BIM technology plays an increasingly important role in the wholelife cycle management of transportation hub projects with its characteristics of three⁃dimensionalvisualization, information integration and collaborative operation. Taking the traffic hub project of QinshuiEast Connection Line as the research object, the application of BIM digital technology in the project isanalyzed. The results show that by optimizing the BIM modeling process and adding model componentparameters in batches, the consistency of data information is ensured, and the modeling speed andmanagement quality of BIM model are improved. Through BIM technology to simulate the constructionprocess, the dynamic adjustment of the construction process is realized, the construction site layout,construction technology and process are optimized, and the construction quality and construction speedare improved. The combination of BIM technology and UAV photography technology can select specificareas for engineering quantity calculation and generate tables, dynamically track the implementation ofthe project, and accurately calculate and allocate engineering resources. Through the MES productionmanagement platform and C⁃Smart intelligent site platform, the project data acquisition mobile,production early warning intelligent, decision⁃making scheduling online are realized, and the project iscarried out. Environmental monitoring, real⁃time monitoring, safety management, quality management,etc. , have promoted the development of digital construction of transportation hub projects.
