The revolution of IT (Information Technology) and software for AEC industry have not changed the traditional constructing management patterns, and construction efficiency has not been improved sharply.According to the results, this paper explores design management patterns based on BIM (Building Information Modeling), and it refers to the subject "exploring the key coordination and management digital technologies based on the EXPO group buildings", and the Headquarters Bases for Central Government Owned Enterprises within the EXPO site is used as a case.After analyzing the features of complex group buildings and BIM technology, design management patterns based on BIM are explored.

In recent years, building information model (BIM) has not only developed rapidly in theory, but has also been widely used in the project practice.However, the combination of BIM technology and project management research and practice is still relatively rare.In this paper, based on the characteristics of the project management and the BIM technology application, and treating BIM as a kind of management environment, the project management process is explored as BIM applied to the traditional project management process.In the meanwhile, the BIM application process in project management is analyzed in this paper.And the key problems occurred when BIM is applied to the project management are discussed.

The Study based on the background of Shanghai Expo central enterprises headquarters base project, In this project, we use BIM through all general design control process, which make high quality result in Shanghai Expo central enterprises headquarters base project. The project as a standard case, hope to bring useful experience for the city future development.
