The Ningbo Zhongxing is a cable-stayed bridge with single-cable-plane and low-tower, which possesses the largest span currently in the world. The construction condition of the bridge is harsh, the bridge structure is complex, and the construction site is limited. From the very beginning of the design phase, the projects starts adopting the independent developed software for the BIM forward design, which employs modern technologies including the tilted photography and virtual reality. This is for the first time that the integration of tilted photography and virtual reality is applied in the construction of domestic large municipal bridge project in China. The performance analysis and design optimization of the BIM model are carried out with a variety of software, which lays a good foundation for the application of BIM technology and its future development.

Ningbo Meishan Chunxiao Bridge is the first all welded steel bridge with vertical shift type of double layer. This article introduces the process of making three-dimensional forward design of the bridge by independently developed BIM software, shares multiple specialty data information through unified management of platform. It also combines several applications to optimize BIM technology. Among them, the successful use of new technology such as unmanned aerial vehicle terrain survey, virtual reality, test assembling of digital scan also laid a good foundation for the BIM development of the similar projects.
