The construction industry is an important pillar industry of China′s national economic development. Today, with the rapid development of information technology, the traditional construction has been faced with unprecedented challenges, followed by the continuous promotion of digitization and informatization. BIM Technology is the product of digital development. At present, BIM Technology has been applied to architectural design and construction as a broad concept. With the maturity of technology and the improvement of implementation ability, BIM Technology has shown a well-deserved great value in the productivity revolution technology of the construction industry. As large-scale public buildings, Sports venues′ construction is a living specimen and cultural symbol of the development of a city and even the whole country. Compared with general civil buildings, they have the characteristics of functionality, aggregation, sociality, science and technology. Therefore, their construction process also faces many complex problems. As a new technology to achieve the transformation and upgrading of the construction industry, BIM Technology has become an effective tool to solve the design, construction and operation and maintenance of complex projects. Taking Lanzhou Olympic Sports Center project as an example, the paper systematically expounds the comprehensive application of BIM Technology in the design and construction of special-shaped buildings in large sports venues clusters, and actively innovates and expands the application of BIM+N new technology.
