As the main venue of the 81st World Science Fiction Convention, Chengdu Science Museum was designed by Zaha Hadid's team, and the scheme integrates numerous cultural elements e.g., "nebula, Sanxingdui gold mask, and the eye of ancient Shu". The exterior of the building resembles an oriental star island floating in space. The whole building is distorted, and the application of BIM technology ensures the quality of the design and construction of the project. Through the application of BIM visualization, BIM parameterization and other technologies, the difficult points of complex building shape and multiple construction processes have been solved decently. The successful application of BIM technology in Chengdu Science Museum has enhanced the added value of BIM technology in the curtain wall industry, expanded the breadth of BIM technology application, which demonstrates the direction for the application of BIM technology in future special-shaped venues design.
