摘　　要：为改进目前预制装配式建筑预制率手工计算存在效率低下、误差加大的问题,本研究利用建筑信息模型BIM技术,通过对Revit软件的二次开发,实现了对基于BIM模型的预制装配式混凝土建筑(Precast Concrete,简称PC)预制构件工程量的自动统计和预制率的自动计算,验证了基于Revit平台计算PC建筑预制率的可行性。利用本文的二次开发成果,通过不同构件预制率的动态选择组合,可以估算建设成本,进而选择成本可接受范围内的预制方案,增加经济效益,为决策者制定预制方案提供决策依据。In order to improve the current prefabricated building prefabrication rate calculation, and to solve the problems of low efficiency and large error existed in the manual calculation, this study applies the BIM technologyto achieve the automatic statistics of precast concrete components and automatic calculation of precast rate for a PC building based on its BIM model through the secondary development on Revit, which verifies the feasibility of calculating PC building precast rate based on Revit platform. Based on the results of secondary development in this paper, the construction cost can be estimated directly when selecting different combinations of prefabrication rates, and then the prefabrication schemes within acceptable cost range can be selected, to increase economic benefits, and to provide decision-making basis for decision makers to formulate prefabrication schemes.
