摘要

臺灣於民國103年起從公共工程逐步推動建築資訊模型(Building Information Modeling， BIM)技術，各縣市政府陸續將BIM納入採購招標文件中，對於營造廠而言，使用BIM為一必要之事，但BIM軟硬體建置及人才培育成本較高，且導入既有作業流程及管理系統不易，因此，導入BIM後所帶來的效益，影響營造廠對於導入BIM技術的積極性。
國外已有文獻提出BIM所帶來效益計算，但效益評估架構需考慮地區產業及特性，因此本研究收集國外效益評估案例，彙整BIM可達到之效益，經由可行性評估，建立一適合於臺灣營造廠導入BIM後之效益評估架構與方法，擬定之指標架構可分為四大項，分別為(1)重做成本之減省效果(RCR)；(2)施工介面協調或重做所致延遲之改善效果(SDR)；(3)潛在逾期罰款減省百分比(DPR)；(4)資源用量精確化效果(AQE)。
本研究根據訂定之指標以一實際營建工程個案進行效益評估演算，演算結果除了對於因導入專案未使用BIM估算數量而無法驗證資源用量精確化效果(AQE)指標外，對於其餘三項指標，則驗證此效益評估架構確實具實務可操作性。

Since 2014, public construction projects in Taiwan have progressively undertaken steps to promote the use of Building Information Modeling (BIM) technology, where many city governments have even incorporated BIM as part of the procurement and bidding documents. From a contractor’s perspective, the use of BIM has therefore become a necessity. However, issues such as the high upfront costs relating to software and hardware setup and BIM user training, combined with the difficulties of incorporating BIM into existing workflow operations and management systems, remain a challenge to contractors. Consequently, the benefits stemming from the BIM implementation in turn will affect the activeness and enthusiasm of contractors to implement BIM.
While there have been previous studies abroad where the benefits relating to BIM implementation had been calculated and quantified numerically, a complete benefit assessment framework would require considerations for regional industry practices and characteristics. This study examined numerous benefit assessment case studies from abroad to collect and organize the potential benefits BIM implementation can provide, followed by the use of feasibility assessments to establish a benefit assessment framework and method for the implementation of BIM that would prove most suitable for contractors in Taiwan. The framework indexes were classified into the four major categories of (1) RCR means effects of reducing or eliminating costs associated with rework; (2) SDR means effects of mitigating delays that occur due to construction interface coordination or rework; (3) DPR means percentage of the reduction in penalty costs associated with construction delays or overdue delivery; (4) AQE means effect of the ability to document building material and resource usage with accuracy and precision.
This study also performed a benefit assessment calculation of a real world case study construction project using the established indexes. While the AQE index was not used due to the case study project not utilizing BIM to document material and resource usage, the rest of the results showed that the indexes RCR, SDR, and DPR were ably used to demonstrate the applicability of the benefit assessment framework to actual real world construction projects.
