從比較場鑄與預鑄T型涵洞之興建與減碳效益來探討組織導入BIM之策略

Abstract

本研究旨在探討場鑄與預鑄T型涵洞施工方式的差異，並進一步分析建築資訊塑模（BIM）技術在施工過程中的應用，特別是在提升施工效率和減少碳排放方面的潛力。以台灣電力公司地下電纜T型涵洞及輸電線路土木工程為案例，研究運用4D BIM技術及碳足跡計算工具，綜合評估兩種施工工法在材料、施工、進度、成本及碳排放等五大面向的差異。結果顯示，預鑄工法在成本上與場鑄工法相當，但在其他指標如碳排放和施工效率上展現顯著優勢，尤其在製造過程中可減少約22.4%的碳排放，為台電公司未來土建構造物的減碳提供可行之策略方針。 此外，本研究還探討了BIM技術在輸電線路土木工程（如鐵塔基礎）中的應用，使用Autodesk Revit建立參數化模型，並根據台大土木工程資訊模擬與管理研究中心的理論架構，提出BIM深化技術運用的參考建議。透過初級資料分析法、程式塑模模擬法，擬定組織導入BIM規範的初步雛型，並建議分階段的導入策略，包括資訊整合、人才培育與流程改善，以提高設計與施工階段的工作效率。 本研究的結果不僅為選擇場鑄與預鑄工法提供了減碳效益和施工效率的實證依據，還為組織導入BIM技術提供了具體的執行建議，期望能促進台灣建設產業實現永續發展早日達成數位轉型目標。

This study investigates the differences between cast-in-place and precast construction methods for T-shaped cable culverts, with a particular focus on the application of Building Information Modeling （BIM） technology in enhancing construction efficiency and reducing carbon emissions. Using Taiwan Power Company’s underground transmission civil works as a representative case, the research adopts 4D BIM simulation combined with life cycle carbon footprint assessment tools to conduct a comprehensive evaluation across five key dimensions: materials, construction processes, project scheduling, cost, and carbon emissions. The findings indicate that while precast construction incurs costs comparable to cast-in-place methods, it demonstrates significant advantages in terms of construction efficiency and environmental impact—particularly achieving an estimated 22.4% reduction in carbon emissions during the manufacturing stage. These results offer practical guidance for low-carbon strategies in civil infrastructure development. Furthermore, the study explores the broader applicability of BIM in transmission line civil works, such as tower foundation modeling. Parametric modeling was performed using Autodesk Revit, guided by the theoretical framework established by the Civil Engineering Information Modeling and Management Research Center at National Taiwan University. The research proposes a phased strategy for organizational BIM adoption, encompassing data integration, workforce training, and process optimization. Methodologically, a combination of primary data analysis and procedural simulation was employed to formulate a preliminary framework for BIM standard implementation. Overall, this study not only provides empirical evidence supporting the benefits of precast construction in terms of carbon reduction and operational efficiency but also delivers actionable recommendations for BIM integration within utility-based construction organizations. The proposed approach aims to contribute to Taiwan’s sustainable development agenda and accelerate the digital transformation of the construction industry.
