摘要
针对目前Revit软件对基坑工程造价计算功能的缺失,提出将基坑工程建筑信息模型(BIM)全过程构件族类化,并利用Revit API二次开发技术实现基坑工程造价自动化计算。首先,利用Revit平台建立基坑工程BIM模型构建族类库,实现基坑工程支护结构族类参数化;然后,对基坑工程造价计算流程进行分析,利用Revit API二次开发技术自动获取基坑工程项目BIM模型中各类构件参数,并结合基坑工程造价计算公式,实现实际工程量计算、定额套用、数据的显示与输出等功能;最后,以长沙市某基坑工程为例,开展实际工程项目的自动化造价计算,验证上述基于Revit的基坑工程造价计算插件的可行性。结果表明,本文开发的Revit造价计算插件可以基于导入的基坑工程BIM模型实现自动化造价计算,且与人工计算结果吻合良好。这一技术的实现,弥补了Revit软件在基坑工程造价计算以及基坑工程造价方面功能的不足,提高设计人员的工作效率,为进一步扩展BIM技术在基坑工程中的应用打下良好基础。
In view of the lack of the function for cost calculation of foundation pit project in the current Revit software,this paper proposes using the Revit API secondary development technology is to realize the automatic calculation of foundation pit project cost based on the foundation pit project building information modeling(BIM)component family.Firstly,Revit platform is used to establish the BIM model of a foundation pit project and realize the parameterization of the family class of supporting structures of foundation pit projects. Then,with the knowledge of calculation process of foundation pit project cost,the Revit API secondary development technology is used to automatically obtain the parameters of various components in the BIM model of foundation pit project,and to realize the actual quantity calculation,quota application,display and output of data,etc.,based on the calculation formula of foundation pit project cost. Finally,taking a foundation pit project in Changsha city as an example,the automated cost calculation of the actual project is carried out to verify the feasibility of the above Revit-based foundation pit project cost calculation plug-in. The results show that the Revit cost calculation plug-in developed in this paper can achieve automatic cost calculation based on the imported BIM model of foundation pit project,and the results match well with manual calculation. The implementation of this technology makes up for the inadequacy of Revit software in the calculation of foundation pit project cost and foundation pit project cost,improves the efficiency of designers and lays a good foundation for further expanding the application of BIM technology in foundation pit projects.
