Abstract: During the implementation of the building project, there is great deal of information to be processed. How to effectively organize and utilize these information, exchange and share data between different departments and personnel, has become a crucial problem in improving the information technology application level in construction industry. Based on the industry foundation classes (IFC) st andard and the 4D modeling theory, this paper describes the establishmentof a 4D information model that supports the data exchange and sharing during construction phases and achieves the integrated information management. A 4D project management system is also introduced. This system enables dynamic management, optimization and 4D simulation of the construction schedule, the resource allocation and the construction site layout. The model and the system provide new theory, approach and method for engineering information management during the whole construction phases. It may serve as a new construction management tool.
