國內營造業之職業災害類型，以墜落、倒塌、崩塌、感電、物體飛落等類型為主，而近十年間，營造業重大職災中災害類型以墜落、滾落高居榜首，其中建築施工階段開口之墜落或滾落問題，一直是營造業勞工安全的最大威脅。
本研究使用建築資訊模型(Building Information Modeling, BIM) 與視覺化程式語言(Visual Programming Language, VPL)這兩種技術，使用施工規劃階段之BIM模型找出可能發生墜落的位置，並自動佈設安全防護設施以期能降低墜落發生的風險。由於BIM技術在近年來逐漸發展成熟且風行，是應用於營造業的主流趨勢，BIM可使用三維數值模型表達真實構件之空間關係，並可結合排程模擬現場施工順序進而檢討工序。視覺化程式語言的應用軟體Dynamo能輔助Autodesk Revit進行程式的開發，擴充建模軟體本身的功能。因此在施工之前若能善用BIM的技術，分析出人為可能忽略所造成墜落風險的位置，未來在實際建造時於施工開口處設置安全防護設施，並透過 BIM 所提供之相關資訊為基礎，達到改進傳統人工進行安全規劃之效率，如此一來將可提供現場作業人員即時且正確的安全防護資訊，可以有效提升施工開口墜落防制之成效，來降低勞工職業墜落災害的發生。
透過本研究開發之程式，搭配施工規劃階段之模型，可以自動找出模型內之開口位置，即有墜落風險的位置，亦可使用本研究來自動放置防護設施於可能會造成墜落風險處，並輸出相關防護設施之資訊，如此一來，既取代傳統耗時的人工檢查，也能降低一定的成本及人為疏失的發生。

Falling, collapsing, electric shock, and flying objects are major occupational hazards in Taiwan. In the construction industry, falling is the number occupational hazard in the past ten years.
This study adopts Building Information Modeling (BIM) and Visual Programming Language (VPL) technologies to help reduce the risk in construction sites. Automated procedures are developed to identify openings and to install fall-prevention equipment in BIM. BIM technologies are maturing and adoption rate has kept increasing. The 3D nature of BIM can help achieve better designs and help construction planning. Dynamo is a VPL that can extend Autodesk Revit to develop new functionalities. By using the developed automated procedures in this research, openings in the BIM model can be identified automatically. Model components representing are also created and installed by developed procedures to prevent falling. Thus, the developed procedures can greatly improve the efficiency of safety planning and in turn reduce falling hazards during construction.
