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.
