Large-scale public exhibition hall buildings have the characteristics of large space, large span, large stories and so on, which makes the complex loading of the building, the large gradient change of the shape, the difficulties in the detail design, and the complexities in the construction, which demand very high requirements during the design and construction phases. This paper using example of Hubei Science and Technology New Museum, which has implemented BIM Technology to solve the acoustic problems in large space during the design phase. Based on the Tekla software, the steel structure has been detailed designed, integrated with technologies in digital constructions such as BIM and QR code, the construction process is visualized, which has improved the construction efficiencies, has reduced the quality control risks, and has provided experience for the construction of large-scale exhibition hall.
