摘要： ：BIM 作为一种新的理念与技术，正引发建筑行业的变革。然而BIM 应用中工程
量计算的可靠性与灵活性难以兼容，数据处理过程过于复杂冗长，并没有真正地优化算量流
程和提高算量效率。本文基于IFC 标准对工程量自动计算方法进行探讨与研究，分析IFC 标
准中典型梁柱构件几何信息、关联信息的描述方法，借助几何方程实现节点重叠体积的计算，
得到符合我国计量标准的混凝土工程量。结果表明，基于IFC 标准的构件工程量自动计算方
法是可行有效的，能够提高工程算量的效率与精度，并实现工程量计算与建模软件及绘制路
径的无关性。

Abstract: As a new concept and technology, Building Information Modeling is raising a new
revolution in AEC/FM (architecture, engineering, construction and facility management) industry.
However, the reliability and the flexibility of quantity calculation using BIM technology are difficult
to coexist due to the complexity of data processing, the current BIM application fails to optimize the
calculation process and improve the efficiency. Based on the IFC standard, this paper conducts a
research about automatic calculation method of quantity. By analyzing the IFC-based expression of a
typical beam-column joint and formulating the geometric equations of the related components, the
overlap volume of beam-column which will meet the requirements of GB50500-2013 can be
calculated automatically. This research proves that the IFC-based calculation method is feasible and
able to improve the efficiency and precision of quantity take-off, which also demonstrates that the
quantity take-off method can be irrelevant with BIM software and modeling paths.
