摘要: | 公共工程乃是政府預算支出之大宗,選擇適當的合約型態讓合適的廠商來辦理公共工程,使資源之效能極大化,便是營建業需共同努力之目標。契約型態的選擇雖只是整個工程生命週期中的一個環節,其所佔的作業時間雖短,但對整個工程所產生的影響卻不容忽視。
民國八十七年5月27日公布「政府採購法」,其中第24條規定有關招標得以「統包」之方式來辦理,國內公共工程主辦機關採用統包始有法可依循。根據工程會的統計,統包工程標案的數量及金額也有逐年增加的趨勢。
過往的研究都是針對數個實際案例來探討其工期、經費之效益,有可能因為樣本數過少而造成偏差,甚少有利用大量的發包案例來進行統計分析、利用較客觀的方式來評估工期、經費之效益的不同。
故本研究利用所收集到的民國91到93年發包之1248件的統包實際案例與民國91到93年發包之57323筆的非統包案例作比較。針對基本資料(工程屬性、工程類別、決標方式)、經費部分(發包預算、標比、變更設計金額、經費增減)、工期部份(契約工期、工期展延、進度差異)作統計分析比較,並利用卡方檢定及對數線性模式的分析判斷是否有相關性存在。 Design-build (DB) delivery method is increasingly used in Taiwan due to numerous advantages it can offer a project. Design-build and conventional delivery system are two principal project delivery systems use in Taiwan today. Numerous foreign studies have advocated the use of design-build over the conventional delivery approach. The study first collects 1248 public Design-build projects and 57323 public conventional construction projects. The performance makes the analysis by quality cost and schedule. This research analysis performance of public D/B and public conventional construction projects by using chi-square test and log-linear modal. The analysis results has to assist contractor making the decision and realize the performance difference between Design-build and conventional construction projects in Taiwan. |
