Data for An Automatic Design-feedback Process for Structural Prefabricated Components Quantity Take-off Calculation Using BIM

The objective of this research is to create an automated design feedback workflow serving QTO for structural components using Dynamo, a BIM-assisted visual programming tool. A BPMN(Business Process Modeling Notation) Diagram drawn up with Visio software can clearly show the flow forms of data types and information between 'Client', 'Structure Engineer' and 'Estimator'; UML (Unified Modeling Language) Diagram can be used to classify, construct, document, interpret and visualize numerous elements of a dense system using a standardized language to make the data hierarchy clear and the information explicit; Revit Dynamo scripts are used to automate the design-feedback process; Detailed data of the study results are presented in Project Data.本研究旨在依托BIM（建筑信息模型，Building Information Modeling）辅助可视化编程工具Dynamo，构建面向结构构件工程量统计（Quantity Takeoff, QTO）的自动化设计反馈工作流。借助Visio软件绘制的BPMN（业务流程模型与标记法，Business Process Modeling Notation）流程图，可清晰展现「客户」「结构工程师」与「估算师」之间的数据类型与信息流向；UML（统一建模语言，Unified Modeling Language）图则可通过标准化语言，对复杂系统的诸多要素进行分类、构建、文档化、阐释与可视化，从而明晰数据层级、明确信息内涵；本研究采用Revit Dynamo脚本实现设计反馈流程的自动化；研究成果的详细数据将收录于项目数据集（Project Data）中。
