Building information model (BIM) has become the mainstream in the contemporary architecture industry, which can integrate all construction project information during the life cycle, including all stages such as the survey, design, construction, delivery, use, operation, maintenance and so on. For BIM, IFC is a commonly used format which is an oriented file format with a data model to facilitate interoperability in the building industry. Besides, OA system is an efficient manager for information data while IFC standard is a kind of data expression standard for construction products. With data flow-oriented design of OA system based on IFC, the management and application of IFC data with large number and complex structure are easily worked out, which makes sharing and utilization of resources during life cycle more efficient. This article deals with a detailed analysis of the IFC data format. According to the general principle of data flow-oriented design of OA system, the framework of data flow-oriented design based on IFC is proposed, as well as the framework of storage module and the extension method of the data dictionary based on IFC, which brings great convenience for model and big data management of enterprises.
