Abstract: Based on the engineering practice of Hangzhou Yuhang International Sports Center project, this paper integrates and combines cutting-edge technologies such as AI, AR, UAV, point cloud scanning and 3D printing and carries out an innovative and creative application of BIM technology. The implementation planning, main innovation and application strategies of BIM technology application have been systematically summarized and expounded. The application requirements and effects of various technologies have been analyzed. Based on the practice, the main conclusions are as follows: In the construction of large stadiums, the application of BIM technology is a holistic task, and it is of great significance to do a good job in the implementation planning of the entire cycle. Simulation analysis, design optimization and construction deployment comparison are firstly carried out based on the visualization of the model, which can effectively facilitate the intelligent construction and enhance the quality of design and construction. Secondly, deepening the design and optimization is the basis of high-quality on-site construction, which requires all professional synergy, and strive to become a good, in-depth integration.. In addition, The innovative combination of BIM with AI, point cloud scanning, 3D printing and other cutting-edge technologies can bring considerable convenience and benefits to the project. The entire process of professional integrated management can significantly reduce management costs and remarkably improve the level of fine management.
