| 摘要: | 應用建築資訊建模(Building Information Modeling, BIM)技術是近年來營建產業非常重要的一項發展。過去的研究顯示，為了評估、量測與強化BIM應用的商業價值，產業參與者與研究人員有高度的興趣進行BIM應用的不同面向評估，且過往多數研究會經由分析釋疑單(Request For Information, RFI)的數量來掌握應用BIM的金錢與管理上的價值，然而對於RFI的深入研究與分析卻相對有限。本研究提出一個以投資報酬率(ROI)為主軸且包含三個不同面向的BIM應用價值評估架構，進而討論RFI在成本節省與時間節省的價值。此外，本研究並以問卷調查取得BIM應用參與者的回饋資訊後，探索應用BIM的參與者在RFI五個元素的BIM預期價值。經由分析後，本研究認為RFI的價值可以經由ROI的三個面向獲得解釋：(1)在專案面向，規模較大與契約金額較高且較為複雜的專案RFI的價值較高；(2)在利害關係人面向，業主與顧問較其他專案參與者能夠認同RFI帶來的價值；(3)在BIM成熟度面向，較高的BIM成熟度能夠獲得較高的RFI價值。期望本研究之成果能夠提供組織，尤其是在近期想要了解BIM是否值得投資的業主，做為掌握BIM價值的重要參考資料。;Implementing Building Information Modeling (BIM) technology is one of the most significant developments in the architecture, engineering and construction (AEC) industry recently. The previous research showed that there is an intense interest among the industry practitioners and academic researchers to assess different aspects of BIM implementation in order to evaluate, measure and enhance the business value of BIM. Although previous researches have mentioned the monetary and managerial values in dealing with the number of Request For Information (RFI), the reality of the situation is that a limited research has discussed broadly and methodically the RFI metric with BIM implementation assessment. The objectives of this study are to discuss primarily the RFI values in terms of cost-saving and time-saving by developing a systematical framework in three different dimensions of Return On Investment (ROI) in implementing BIM, and to explore the potential RFI’s elements under BIM players’ perceptions by conducting a questionnaire survey. By determining the cost and time values associated with five RFI elements (RFI response, RFI reduction, RFI process, RFI reissue, and pending RFI), this study concludes that the RFI metric is a potential measure in perceiving the BIM benefits. Furthermore, the values of RFI fully explored in three distinct dimensions of ROI are interpreted that: (1) In project dimension, the larger project scale and contract value, with more complexity there are, the higher RFI value can be achieved; (2) In stakeholder dimension, owners and consultants perceived the highest RFI value comparing to other BIM players; (3) In BIM maturity level dimension, a higher RFI value would have been reported in the higher BIM maturity levels. Hopefully, the research findings can provide essential information for organizations, particularly to owners who want to know whether BIM is valuable to invest in the near future. |
