A study of Cost and Quality of BOT Project—the Case of Kaohsiung Mass Rapid Transit

[[abstract]]近年來因政府預算愈來愈短絀，因此目前許多重大的公共工程採取BOT(Build-Operate-Transfer，興建-營運-移轉)之採購模式結合民間投資，乃期望透過引進民間工程的效率，達到減輕政府財務負擔之目標。然而現階段高雄捷運工程以政府出資比例佔大部分之BOT專案計畫，其是否能達成民間參與公共工程之效率，相當值得探討。 本研究以台北捷運（傳統工程）及高雄捷運（BOT工程）為案例，探討BOT專案工程之成本與品質。首先分析台北捷運及高雄捷運之發包合約單價，計算出潛盾隧道每M單價，然後再以主辦機關、股東、承包商及顧問公司四個參與捷運工程不同角色的問卷調查，交叉分析工程品質。 整體而言，高雄捷運工程之造價較台北捷運工程為高而施工品質卻反而較低，其明顯表示由政府出資比例佔大部分之BOT專案工程，就其成本與品質而言，皆不如傳統工程之執行方式，該類型之BOT專案計畫不但未能達到引進民間資金之目的，同時更可能導致工程績效下降，確有相當檢討及改善之空間。[[abstract]]Due to scarcity and shortage of fund by the government in the recent years, so far many of the major public projects are given out in a form of BOT construction by involving private enterprises participating in public construction project, it is to anticipate that it can reach the target of reducing government finance pressure to connect with construction work efficiency of private enterprise. However, so far whether Kaohsiung MRT (BOT project), fund given mostly from government, can get the efficiency by the private participating in the public work is worth our studying. This research focuses on the quality and cost of BOT project study by taking the case of Kaohsiung MRT (BOT project) and Taipei MRT (Design/Bid/Build project). The unit price of the shield tunnel per M is calculated out by analyzing the unit price of Taipei MRT and Kaohsiung MRT contract issued for tender. And the construction work quality is also analyzed by the cross analysis of questionnaire from the responsible entity, shareholders, contractors and consultancy companies the four different roles participating MRT project. Comprehensively, the total price of Kaohsiung MRT is higher than Taipei MRT, but its construction quality is lower than its counterpart. It indicated clearly that BOT project, fund given mostly from government, is not as good as the traditional executive manner of Design/Bid/Build project. Not only does BOT project fail to correct sufficient fund from private enterprise, it also may contribute to bad performance of the work. Therefore, there are definitely some portions of BOT project required for review and improvement
