This paper summarizes the successful application of BIM-based design visualization in the German Pavilion of EXPO 2010.By using Revit and Navisworks, discipline collaboration and collision detection can be done in 3D environment while it is almost impossible in 2D.Meanwhile, data exchanges between design firms and contractors have been improved through the BIM technology.

As a national-level new district, Nansha New Area has a superior geographical location and advanced position. The Pearl Bay starting area is the core area of Guangdong-Hong Kong-Macao cooperation and a comprehensive service center that is built by the Nansha New Area and set high-quality construction innovation standards. In order to adapt to the planning concept and construction requirements of Pearl Bay, Pearl Bay Development Authority has developed an engineering management information system suitable for the administration′s construction project management. Starting from the visualization, dynamic, and refined management of progress of works, investment, quality, safety, operation and maintenance, and the integrated collaborative management of the development and construction of the whole district, the traditional project management model has been changed through information technology. At the same time, the information technology has proposed some new ideas for project management. This article selects six typical new ideas in the project management information system to introduce, summarizing the advantages of this management system, and hopes to provide some reference for the construction of other new districts.

BIM technology has developed rapidly in recent years and it also was successfully introduced to Hei Xiazi Botanical Garden in early architectural design.CFD technology is widely used in the architectural design of building wind environment.The thesis is focus on the introduction of the application of CFD technology combination with BIM technology.The building wind environment out side, the indoor natural ventilation and the indoor air flow field were calculated out by CFD software package.According to the computation results, Hei Xia-zi building layout was adjusted dynamicly to optimize the design.Meanwhile, according to CFD calculation of indoor temperature and humidity fields and checking the conditions of plant growth needs, the local air conditioning technology was used to save energy.
