ABSTRACT

Although the modular construction method is safer than traditional onsite construction methods, accidents still occur; therefore, modular projects have characteristic safety risks. This study investigated accident cases related to modular construction and identified the safety risk factors. The study evaluated accident cases related to modular construction that occurred in the United States from 2000 to 2018 and analyzed safety risk factors, such as the types and causes of accidents in these cases. In the process of analysis, the causal map was developed and it was used to identify the causes of accidents. The results of the analyses showed the major accident causes and types that occurred in these activities. Second, this study conducted a comparative analysis to identify differences between accidents in modular and general constructions. Furthermore, suggestions are proposed to prevent safety accidents and to develop management schemes based on the analyzed outcomes. This study contributes to the body of knowledge as a basic modular construction safety management study; it presents safety risk factors by identifying safety accidents in modular construction projects and helps safety managers frame appropriate measures when making decisions.

摘要

模块化施工方式虽然比传统的现场施工方式更安全，但事故依然时有发生；因此，模块化项目具有特有的安全风险。本研究调查了与模块化结构相关的事故案例，并确定了安全风险因素。该研究评估了 2000 年至 2018 年在美国发生的与模块化结构相关的事故案例，并分析了这些案例中事故的类型和原因等安全风险因素。在分析过程中，形成了因果图，用于识别事故原因。分析结果显示了这些活动中发生的主要事故原因和类型。其次，本研究进行了比较分析，以确定模块化和一般结构事故之间的差异。此外，还提出了预防安全事故的建议，并根据分析结果制定管理方案。本研究作为基本的模块化施工安全管理研究有助于知识体系；它通过识别模块化建筑项目中的安全事故来呈现安全风险因素，并帮助安全管理人员在做出决策时制定适当的措施。
