摘要

由於捷運工程施工工期長，工程項目眾多且複雜，針對無法以明確單位計價的項目或是尚未確認施工工法的項目，大多採取以「1式」做為計價單位，這些項目稱為乙式計價項目(包括一般規定、安全衛生費、環境保護費、品質管理費等)。本研究藉由三件實際案例分析乙式計價項目之量化情形，並分別運用不同量化方法(包括工期比例法、工程進度百分比法、計價進度百分比法等)，探討採用不同量化方法所造成之差異。經過本研究分析後，發現不同的量化方法雖對於施工廠商實際可請領之總金額並無差異，但因請領時間不同將造成利息上的損失，為求其公平與減少執行上之爭議，建議將乙式計價之相關規定訂於契約條款中，使各工程標案於計價時能有所依循並達到雙贏之目的。

In a Mass Rapid Transit (MRT) construction project, the construction duration usually is very long and construction pay items are numerous. Some pay items that cannot be easily quantified are treated as ＂lump-sum-based pay items＂. These lump-sum-based pay items are such as general requirement fees, safety fees, environmental protection fees, and quality control fees. Based on three cases projects, this work analyzes how the lump-sum-based pay items are quantified using three different evaluation methods (namely, working duration method, field progress method, and payment progress method). The case studies indicate that a contractor can earn substantially different interests by applying different evaluation methods, although he will receive the same principal (i.e., total amount of payments) eventually. Hence, this investigation suggests that the use of a particular evaluation method of lump-sum-based pay items be included in the contractual provisions of a MRT construction project for preventing potential disputes.
