This paper mainly summarizes the successful application of BIM-based design visualization in the Hangzhou-East Railway Station project. For Hangzhou East Railway Station project, as one of giant hub stations, its main steel structure is highly complex and quite difficult to construct. By means of three-dimensional modeling and construction simulation software of PKPM series, the complex spatial relations and steel erection installation of the structure are solved well. Building information modeling (BIM) improved design and construction programs better.
