公共工程委託監造部分，現行多數探討二級品保缺失、工程進度管理、界面權責劃分等問題，及其相關層面亦有深入研究資訊，但對於委辦監造施工安全管理監督面臨問題及解決方案，則鮮少探究。本研究藉由臺中鐵路高架化計專案工程資料蒐集與調查，分析探討目前監造單位執行安衛管理所面臨問題、制度盲點，並尋求解決方案提出建議，以供國內於施工安全管理暨監督工作上之參研，始能有較為一致且妥善可行之作業方式，進而降低工安事故發生機率與損失嚴重程度。研究結果顯示監造單位依據與業主間訂立之技術服務契約內容，直接監督施工廠商依工程契約執行各項作業，其同時兼負對施工廠商的工程進度、工程品質、施工安全衛生及環境保護等項之監督管理責任，同時亦面臨自身營利單位人事成本考量問題。施工階段，監造單位能否落實施工安全衛生作業監督，而非僅文書作業之流於型式，則與契約報酬給付方式、權利責任對等、工程業主態度、角色責任衝突及妥協等問題相關。

The commissioned public construction supervising job currently focuses on analyzing the demerits of the secondary quality assurance, managing the construction progress, clarifying the interface responsibilities, etc. Research information on these and related areas are also available. However, the study on problems related to the supervising job on the construction safety of a commissioned public work is seldom found. Based on the Taichung elevated railway project, this study analyzed the possible problems and institutional blind spots that the supervising units were facing when carrying out the safety management through collecting information of projected constructions and aiming to obtain solutions and to propose suggestions to serve as references for managing and supervising the safety of domestic constructions. And, a more agreeable and practicable processing mode is to be generated to result in lowering possibility of accident at work and reducing damage. The results showed that, according to the technical service contract signed with the construction owner, the supervising unit directly supervised the constructor to carry out every detail in the construction contract. The supervising unit was responsible not only for supervising the construction progress, construction quality, construction safety and sanitation, and environmental protection provided by the constructor, but had to watch its own personnel cost on the profit aspect.
