Abstract: Shanghai Riverside Passageway & River-Crossing Tunnel Project is a major Shanghai municipal project with complex traffic system, various types of structures and relative high design difficulty. In this project, we propose a whole life-cycle BIM application process, and we apply BIM technology from general design to specific design in all disciplines. We create design components catalog for municipal transportation projects, and conduct secondary development based on Dassault Systeme 3D Experience platform, which contributes to multiple-disciplinal rapid modeling and parametric design, as well as scenario optimization and design development based on the BIM model. Finally, for the metallic structure, we propose the solution from scenario design, analysis, and optimization to drawing, which lays the foundation for future digital manufacturing.
