The collaborative project management method based on BIM benchmark model can improve our efficiency of project management, because it represents the project as a multi-objective dynamic optimization processfrom original fragmented management of investment, quality and schedule to a benchmark BIM model.The data exchange standards are fundamental and important when we talk about the exchange based on the benchmark model from one single stage to multi-stages of construction projects.In this article, one standard of design construction building information exchange based on BIM is put forward to realize the collaborative project management, which uses a standard data exchange file to solve many problems such as model reuse, information transfer and multi-objective dynamic modification after design changes.
