In order to realize efficiently collaboration in the construction domain, this paper presents a Building Information Model( BIM) cloud platform modeling method for collaborative governance,proposes a BIM collaborative governance framework and divides general BIM application into three patterns, preBIM, BasicBIM and BIMinstance. It defines each BIM pattern with respect to operation,procedure and parallelism,and forms a formal BIM cloud platform model based on object-oriented Petri net theory. This model abstracts BIM cloud platform as four subnets and their interaction relationship. This paper builds Hadoop-based BIM cloud platform with guidance of the proposed model. Collision detection case results show the effectiveness of BIM cloud platform in collaborative governance.%为高效实现建筑工程领域的协同应用,提出一种支持协同治理的建筑信息模型( BIM)云平台建模方法。给出BIM协同治理框架,将BIM应用划分为preBIM,BasicBIM,BIMinstance 3种形态,对每种形态的动作、流程和并行性进行定义。采用面向对象Petri网建立BIM云平台模型,将云平台抽象为4个子网以及子网之间的交互。构建基于Hadoop计算框架的BIM云平台,碰撞检测实例结果验证了BIM云平台在协同治理中的有效性。
