Beijing Zhongguancun Technology Park-Fengtai Innovation Center Project is a high-rise building integrating government office and international business, with a total construction area of 580000 square meters.It has the huge engineering volume, the long construction period and the complex scale of electromechanical pipelines.The complicated construction of curtain wall and landscape is also the feature and difficulty of this project.BIM technology for this project covers the entire life cycle of the building from pre-design, construction to post-operation stage.The main application points of BIM technology are including collaborative management platform, 3D drawing review, electromechanical integrated, construction simulation and the VR application for the key area of hardbound model to insure the successful implementation of the project.In addition, these applications can shorten the construction period, reduce costs, and create a quality building.

The 3D information model of deep foundation pit support of the Hunan Broadcasting System Program Production Project is built through using BIM technology, which brings about the pre-construction of prestressed anchor cable, assisting the civil engineers to detect the construction problems earlier and to take relevant measures to avoid risks.The application of BIM technology is especially for identifying and resolving the collision problem of the prestressed anchor cable in the original design drawings, and then the collision report is submitted to the design institute for the optimization design of the drawings.Meanwhile, the 3D visualization disclosure animation is made for powerful technological support to the project completion punctually and highly-qualified.As a result, considerable economic benefits and significant social benefits are achieved.
