| Abstract: | 台電火力發電廠興建工程早期以傳統採購方式進行，但隨著時代需求，工程規模日益擴增且複雜，傳統採購方式的缺點開始浮現。目前台電火力發電廠的新機組工程之主發電設備採購及現有機組之環保改善設備多以財物(設備)採購兼安裝的統包(D/B)方式辦理，而整個電源開發專案計畫中仍有部份土建工程或機電設備，由台電公司另案採傳統採購方式發包施工。由於火力發電廠興建工程須配合電源線工程及電廠重型設備，由製造至交貨需時相當長，通常及早便開始進行規劃、設計及財務籌措工作；但從過往火力發電廠興建工程案例中發現，工程從計畫初始至完工發電常因各種因素導致延宕，使得完工時程與規劃時程差距甚遠。因此，找出火力發電廠興建工程造成進度落後的因素，並進行預防與改善，對電源開發專案計劃而言是非常重要的工作。本研究透過文獻回顧、過往案例及實務經驗之分析，歸納出影響火力發電廠工程全生命週期各階段影響進度落後之因素，共計7大類，24項影響因素。此外，本研究亦分析統計出影響工程進度落後最主要因素，分別為：「工程進度管控作為」、「設計品質與協調整合」、「施工品質管控」等三大類工作性質缺失，並比較其他統包工程，如變電所工程、輕軌工程及建築工程等，發現台電火力發電廠興建工程與其他工程在影響因素上有所異同，這也顯示台電火力發電廠興建計畫工程必須進行額外的管理工作，才能讓工程進度獲得良好的管控。本研究最終提出各項時程管理缺失的事前預防措施與事後的解決方案，可供未來台電進行火力電廠興建計畫改善進度落後之參考，以降低工程逾期的風險。;In the past, the construction of Taipower’s Thermal Power Plant (TPP) project was carried out by the traditional procurement method (Design-Bid-Build). With the needs of the times, the scale of the TPP project has been increasingly expanded and complicated, and the disadvantages of the traditional procurement method have emerged. At present, the procurement of the main generating equipment of the new generator set and the environmental protection improvement equipment of existing generator set of Taipower’s TPP project are mostly executed through the turnkey contract (Design/Build, D/B) method that contains property procurement and installation works. However, there are still some facility construction or mechanical/electrical equipment in the whole power development project plan, which will be contracted out by Taipower Corporation in traditional procurement ways. Since the construction of TPP must be coordinated with power source cabling work and heavy equipment of the power plant, it takes quite a long time from manufacturing to delivery, of which planning, design and financing are usually started as early as possible. However, it has been found that project schedules (from beginning till completion) of TPP construction projects in the past are usually delayed due to various factors, which result in actual completion schedules far away from the original schedules. Therefore, it is vital for the power source development project plan to find out the schedule delay factors for the TPP construction project, and then to carry out prevention and improvement works. In this study, through literature review, the analysis on past cases and practical experience, the factors affecting the schedule of the TPP project in all stages of the life cycle have been summarized. The identified 24 factors are classified into 7 categories. In addition, this study also analyzes and identifies the most important factors that affecting project schedules, which are “project progress control measures,” “design quality, coordination and integration,” and “construction quality control.” Those are major work defects for TPP project schdules. Comparing with other D/B contract projects, such as substation projects, construction projects, light rail projects, etc., this study also finds that the construction of Taipower’s TPP project shared differences and commons with from other types pf projects in terms of influencing factors. This study concludes that the construction of Taipower’s TPP project must be subject to additional management in order to make the project schedule well controlled. This study finally proposes various preventive measures and post-event solutions for insufficient schedule management works, which can be used as a reference for improving the schedule quality and reducing the risk of schedule slippage of TPP construction plan in the future |
