An Empirical study on planning and design collaboration of urban railway construction bridge and culvert project based on BIM

Traffic infrastructure construction needs the first introduced project during the urban development process. Good traffic development planning will inevitably bring better conditions for urban development and construction. In this study, BIM technology is introduced into the application of a railway bridge and culvert project in China. Firstly, the application process and framework of BIM technology are planned in A/E firm. Secondly, the BIM model is applied in the planning and design phase of a railway track engineering bridge and culvert project. The project scale is 170km, including 10 project segments, and the BIM technology is fully utilized. Advantages include collaborative design and review, visual analysis, bridge and culvert library, geographic location and elevation analysis, bridge and culvert filling model and space review etc. Finally, the application of this project summarizes the BIM technology in railway bridge and culvert project planning and design collaboration benefits and experience learning as well as discussed.
