During the construction progress, the stadium buildings own the characteristics of extensive involvements, heavy coordination, strong comprehensiveness, and multi influencing factor involvement, which pose challenges to the construction scheme, technology, progress and coordination management. Taking the cultural and sports center project in Chuzhou higher education science and innovation city as an example, this paper introduces in details the application of the BIM technology in the stadium project, aiming at solving the construction problems of the stadium. The building possesses the unique appearance design of "flying cloud and dancing swallow", which embodies the many characteristics of large span and complex structure of steel structure engineering, high precision requirement of metal roof installation, and diversified decorative materials, putting forward high requirements for site construction management. The BIM application is able to plan the overall application implementation, and to conduct visual disclosure of complex nodes and construction process, improving the construction quality. A project-level cloud coordination platform is established with refined material tracking system, progress control system and safety monitoring system, which is able to improve the safe and civilized construction environment and to enhance the information management. In view of the key and difficult parts, a BIM based technical scheme simulation is established to solve the problems of difficult processing and high cost of roof hyperboloid panel. The hoisting scheme of steel structure is refined to achieve the goal of small structural deformation, high safety and high accuracy. Finally, on the premise of ensuring the quality of the project, other benefits also achieved including reducing the cost, shortening the construction period and saving materials.

The development of virtual reality (VR) technology makes it possible for users to improve the understanding of dangerous scenes from computational simulations.A prototype system-AutoEscape based on the integration of virtual reality visualization and numerical simulation, was developed for human evacuation in fire scenarios.FDS was selected to simulate the fire growth and an evacuation computational engine was designed and implemented based on GIS technology.A VR representation module was constructed, which develops a comprehensive representation for the distributed scenario variables according to numerical results.The case study indicates that the system can help users to form a deep full-scale understanding of fire evacuations, and therefore provide a virtual training environment for emergency evacuation drills and fire rescue command.
