預製工法的關鍵因素與經濟效益分析─以A公司為例

全球的建築業一直在不斷的興建發展，但施工方式進步卻趨於緩慢停滯，本研究透過理論以及相關文件的參考，並了解現今產業界的發展來討論預製工法對整個業界發展的提升度分析，以A公司為例，耗資將近2億成立預製廠，在現今高成本的時代下，必須擁有足夠的案場工作量，才能利用高成本的預製工法技術帶來高附加價值的經濟效益，預製工法的綜合效益包含利用過去在台灣深耕的經驗以最有效率、最環保、最節能的新系統、新工法做為樓宇系統工程的最大利基。本研究是以A公司工程實際建廠案例，從A公司的預製工法關鍵技術來探討研究，就技術層面的觀點來看，從案場的規劃設計檢討、預製廠內部的加工品質要求、現場施工效率、無形與有形的成本、品質及勞安等各種層面來分析討論，利用管道預製工法在建築產業上開創一種新的工程施作藝術。本研究的管道預製工法是先由3D軟體去將案場做精準的描述設計，然後以預製工廠加工製作出3D規劃設計所需配合料件，再讓僅擁有一般施工經驗的現場人員在現場組裝，這樣的工程工法可以為整個建築產業提高品質，另一方面，本研究從經濟效益的角度切入觀察，無論是大型的案場與特殊結構設計的案場，都可以利用預製工法來解決人力短缺與老化…等問題，並且降低勞工安全成本的增加，所帶來的經濟效益是極大的附加價值。管道預製工法是一種施工藝術也是一種符合多樣化市場需求、降低勞力的依賴、減少工安意外的發生…等優勢的結合，以提高競爭力才能擺脫相關產業紅海的競爭，創造新的藍海版圖，給予業主、消費者及施工人員三方最大的優勢取向，進而達到三贏的營運策略

In the recent years, the entire global construction industry has been in constants development but on the contrary the progress of construction mode is gradually slowing down. Given this emerging issue , this thesis aims at understanding the development of current industry, and thus analyzing the impact of pre -manufacturing technique on industrial evolution by means of theoretical concepts and its related literatures. This thesis is focusing on a real case in “Company A”, which , which has consumed nearly 200 million to set up a pre -fabricated factory . Nowadays the manufacturing and construction costs are inevitably rising. In order to order to survive in this harsh environment , one must have enough construction projects in large scale thus taking advantage of high -cost but high value added prefabricated technology and then to benefit from it. The principles behind this technology include the use of past experience in Taiwan with the most efficient, environmental-friendly and the most energy-saving new methods for building systems. This study investigated "Company A”'s pre-manufacturing core technology. From technical point of view, we started the analysis with the planning and design of each project, requirements in processed products, on-site construction efficiency, the intangible and tangible costs, and ended with security of labor and other subtle topics. Eventually the use of pipeline pre-fabrication in the construction industry as a new engineering art was presented. This study demonstrated that the pipeline pre-fabrication method was first using3D graphic software for precise layout of every construction project, then being followed by manufacturing required materials and components designed from the software. Afterwards, those components are assembled by general construction site staff assemble it in the field. By implementing this methodology, higher efficiency in projects can be achieved. On the other hand, the study also showed that in economical perspective, this type of engineering method can be executed in either large or special-designed construction sites to solve the problems regarding labor shortage, population ageing and so on, whereas reduce cost for ensuring labor safety, which could bring a great deal of benefit to the companies. Pipeline pre-fabrication is a kind of construction "art", and at the same time also a kind of "need" of current diversified markets. It offers, for example, reduction of the dependence on labor, occurrence of accidents, and so on. With these advantages one is able to be more competitive than potential competitors, thus even creating a new “blue ocean map” that gives owners, consumers and construction workers the optimized strength, and thus helps to achieve a win-win business relationship.
