Abstract: The BIM straight-forward scenario is applied on the throughout process of Minmetal Chinasouthern Building design for solutions of many problems, including the precise positioning of the non-linear facade, rearrangement of functional partition, and pipeline integration. Furthermore, emphasizing the advantage of dimension in BIM design, evacuation simulation, etc. is also considered in order to achieve the humanized design. Moreover, BIM based interactive design is also implemented among facade design, landscape design and internal design to provide the proprietor a comprehensive impression and technic support of the project.
