The Study of Contract Implementation in Design-Build Model for Rapid Transit System - the case of Kaohsiung Circle Line LRT Project (Phase1)

[[abstract]]本研究以全台第一條輕軌捷運工程，高雄環狀輕軌捷運第一階段統包工程為案例，探討其契約執行所遭遇之問題，並經由訪談軌道相關專業人士，研議於後續輕軌招標時所需改進之方向。研究方法主要採文獻分析與深度訪談兩種方法，本研究以參與高雄輕軌捷運統包工程之成員為研究對象，透過訪談統包團隊之主辦機關、專案管理顧問、監造單位、統包商等專業人士，針對工程期間之執行現況作探討與分析。 綜整專家訪談結果，有關後續輕軌工程招標階段之對策分為招標策略、需求計畫書與採購契約三部分。統計各類之建議對策，過半數專家認為最有利標應以不訂定底價為原則；投標廠商應明確訂定相關工程實績；細部設計顧問應統一發包，以減少介面爭議；訂定細部設計里程碑，即從細部設計階段控管進度，降低工程延誤風險，以及國內未曾施作之工程，應多參考國外案例，並培育相關人才。專家亦提出軌道與路基工程由同一廠商施作、設計人員應派駐於現場及訂定分包商之資格替代條款等。 本研究之案例由第一次進入國內參與工程的外國廠商負責領銜，外國廠商對法令的不孰悉，國內廠商對與輕軌軌道的工程不了解，以及統包團隊內部分工過細，造成介面問題產生等因素，影響契約執行成效，若能藉由相關的方法與機制有效解決，預防重於治療，設計階段即加強時程管制，能較早發掘問題並提早設法解決相關障礙，對於捷運工程整體建設之進度推展一定有莫大的助益。冀望透過本研究對於輕軌工程契約執行之建議對策，於國內輕軌工程建設未來發展時，可在技術整合能力及整體工程進度掌控上能夠有所助益。[[abstract]]The research used the circle line turnkey project (phase I) of Kaohsiung LRT as a case study that is the first light rail transit (LRT) construction in Taiwan to investigate problems during the contract implementation through interviewed with the rail-related professionals to know how to improve tendering procedure of LRT construction in the future Research methods include analysis of literatures and interviews by interviewed the experts of owners project consultant management supervision and contractors who have been participated the circle line design-build project (phase I) of Kaohsiung LRT to research and analysis the the project status during construction According to the results of expert interviews the countermeasures for the tendering phase of the LRT project includes three sections: tendering strategies requests for proposals and procurement contracts Pursuant to the statistics from the proposed countermeasures a majority of the experts believed that the basis for the base price should not be set by the most advantageous tender; tenderers should clearly specify relevant case history; a detailing design consultant should be contracted out to reduce interface disputes; milestones should be set for detailing design the detailing design phase should implement schedule controls to reduce project delay risks and unforeseen domestic projects reference foreign examples and relevant personnel talent should be cultivated Experts also proposed that when track works and substandard works are constructed by the same contractor the designer should send personnel to the site and establish the terms for alternative requirements for sub-contractors Case in this study was a domestic project undertaken by a foreign contractor for the first time The foreign contractor was unfamiliar with Taiwan’s laws and regulations and domestic contractors did not understand LRT construction projects In addition the division of labor of the contractor was too detailed thus many interface problems arose to affect contract implementation effectiveness As prevention is better than cure if problems were solved effectively with relevant methods and mechanisms in advance by reinforcing schedule control at the design phase problems would have been discovered and relevant barriers would have been overcome in advance to benefit the overall construction progress of the LRT project This study hopes to provide countermeasures for LRT contract implementation so as to benefit the development of technical integration capability and overall schedule control for future development of LRT projects in Taiwa
