摘要:在工程项目中，工程量统计是一项繁琐而又非常重要的工作。根据项目的实际需求，在不同阶段需要多次进行工程量统计，而传统的应用人工(手工或采用专业概预算软件)统计的方法，工作量大且统计结果的精确性完全依赖于统计过程的精细程度。本文中采用Revit和Tekla分别建立BIM模型，将钢结构所有构件及节点等全部表达到模型中，并且分类统计各项工程量。分析结果表明，两款软件均可以得到非常精确的工程量，为项目实施提供了真实可靠的依据。本文实践为Revit实施钢结构精确算量，提供了有力的可行性论证和操作方法。

Abstract: In the engineering project, the engineering quantity statistics is a tedious but important work. According to the actual demand of the project, the engineering quantity statistics is necessarily to be carried out for many times at different stages. However, the traditional application of manual(manual or professional budget software)statistics method is heavy in workload and is totally dependent on the fineness of the statistical process. This paper applies the Revit and Tekla software, respectively, to establish the BIM models, with all components and nodes of steel structure expressed, for the statistics on the quantity of various projects based on classifications. The analysis results show that the two software both can obtain accurate engineering quantities, which provides a true and reliable basis for the implementation of the project. The practice in this paper provides a powerful feasibility demonstration and specific operation method for the precise calculation of steel structure by Revit.
