「重工」是往往容易導致工程進度延遲、工程預算超支的主要因素之一，而「重工」的定義藉由統整各個學者的看法及意見，可以得知其共同概念是糾正或調整已完成工作以符合專案要求的過程。因此，重工的影響不僅僅是影響施工廠商或分包商，在營建工程上的各個角色都可能被其影響，如業主、專管單位、監造單位以及承包單位等。
然而在現今國內關於重工的議題研究較為有限，一方面可能是重工是被認定為品質的失敗，施工廠商並沒有意願將類似事件公諸於世，另一方面可能是因為重工事件可大可小，施工廠商容易忽略重工所造成的問題，焦點容易放在如何去修補、搶救，而非有預防重工發生的意識，故在探討如何預防或避免重工的發生相當少見。而本研究認為重工是營建工程上的不確定因素，意即重工的發生是營建工程的風險之一。因此，在回顧國內外文獻之後，本研究欲藉由專家訪談的方式，蒐集並彙整建築工程施工階段之重工案例，以及探討重工案例與施工階段重工原因之間的關聯，並以風險管理中常見使用的失效模式與效應分析方法作分析研究。此外，針對專家訪談後的結果，除了對於失效模式與效應分析表中的各項指標進行更深入的探討外，更針對資歷進行交叉比對分析，以瞭解資歷的不同對於評估重工事件的影響、發生等指標是否會有影響。藉此瞭解在營建工程生命週期的營造施工階段中，各項重工案例及其重工原因所帶來的影響，並提供給相關專業工程人員作爾後的計畫擬定、規劃，以能夠避免、減少重工對營建專案工程所會帶來的影響。

“Rework” is one of the factors that often lead to project schedule delays and project budget overruns. The definition of “Rework” can be understood by integrating the views and opinions of previous studies, and it can be known as the process of correcting or adjusting the completed work to meet the requirements of the project. The impact of rework is affecting not only construction companies or subcontractors, but also various parties in construction projects, such as owners, professional construction managements, supervisors, and contractors.
However, domestic research on issues related to rework is relatively limited. On the one hand, it may be that reworks quality failure, and the construction companies may not intend to make the events public. On the other hand, it may be because rework events can occur at different scales, and construction companies may ignore the problems and focus on how to repair and rescue, rather than to explore how to prevent or avoid the occurrence of rework. This study considers rework as an uncertain risk factor in construction projects. After reviewing the domestic and international literature, this study collects and summarizes rework events in the construction phase of building construction according to expert interviews. This study explores the relationship between rework events and the reasons for rework in the construction phase, and adopts the FMEA methods (Failure Mode and Effects Analysis) for analysis. In addition, this study conducts a cross-comparison analysis on seniority to understand whether the difference in seniority will affect the evaluation of the impact and occurrence of rework events. Overall, the result of this study helps understand the impact of various rework events and their reasons, and assists professional engineers in future planning, so as to avoid and reduce the impact of rework in construction projects.
