The Beijing urban sub-center project possesses three characteristics including extreme time limit stress, high technology content and high construction requirements. From the early planning stages to the final delivery process, the BIM technology is employed for BIM management in all aspects including the technology, schedule, cost, quality, safety, and etc. Our goal is to use BIM technology as the management tool, to solve the difficulties of project management, and to improve the efficiency and decision-making ability of field management. For example, BIM is applied in the whole process of steel structure, so as to promote the performance, to achieve the BIM-based efficiency promotion of project reduction in project, and to realize informatization of project quality and safety management. At the same time, a self-developed intelligent construction management platform is established to implement the technology informatization and management modularization in the process of building construction. Information transformation is no longer from one department to another department, but from department to the project, which breaks the information barrier. The BIM technology is applied by the entire staff, complete professional and whole process, to improve the project management level and realize the perfect performance of the project.
