Abstract: The construction quality and cost control of pile foundation engineering have attracted wide attention. The data of pile foundation engineering is imported based on Revit and Dynamo, and automatic and rapid modeling, calculation and control of pile length are realized through script program. Taking a pile foundation project as an example, the results show that the Revit-based rapid modeling method of pile foundation can reduce more than 90% of the manual error, reduce 50% of the time cost, and increase the construction efficiency by 20%. The results of automatic calculation can be used for pile length control and cost control, which has high efficiency and is convenient for calculation and statistical analysis of pile length. This method can effectively optimize the application efficiency of geological survey data, improve the quality of pile foundation construction, and control the overall cost.
