The Building Information Modeling(BIM), possessing powerful architecture digitizing capability, has been increasingly applied in construction fields and processes during the life cycle.In the architecture designing process, the building information model should be modified several times before perfectly forming a complete project design scheme, and those modification information can provide references for the optimization of the design scheme.However, Revit can not provide detailed recordings or eligible traces of those intermediate state information.In order to achieve all-the-way tracking and improve efficiency of the model modifications, this paper presents a version management scheme of building information modeling based on event monitoring mechanism.Research shows that such a version management scheme can effectively track modification information of various model versions, which facilitates the management of building information modeling.Meanwhile, the version management scheme adopts the mechanism of merging operation information to clear the redundant operation of the same object, which shortens the execution time of the model from the initial state to the target state, and plays a significant role in acceleration.
