All temporary structures at the construction stage are collectively called falsework. As part of the falsework, the importance of system shoring support (SSS) is often overlooked in construction projects, thus causing increasing accidents from SSS collapse. The 2014 occupational accident statistics of the Council of Labor Affairs show that most occupational accidents occurred in the construction industry, and fall and collapse were the most common accidents in the construction industry in Taiwan. Although the SSS is commonly used in construction, no well-defined instruction for the installation and required safety facilities for SSS have been established to provide a dependable guide. The status of SSS used in falsework of construction projects and the types of potential accidents and relevant examples will be investigated. With building information modeling (BIM), this study defined the relevant SSS facilities with the 3D modeling of BIM. This research drew the actual status of the erection of SSS on the construction site with the Revit from Autodesk to provide a communication platform for engineers, SSS contractors, and labor safety and health personnel. The corresponding preventive measures in terms of safety passages and stairs have been proposed for the reference of engineering personnel in construction site. Through the help of this study, the construction falsework safety can be enhanced and the accidents of SSS can be minimized.
