摘要

唯有充份應用建築資訊模型(Building Information Modeling, BIM)中的資訊，才能彌補投入BIM的成本且創造額外的價值。美國BIM規範提出以全分類(OmniClass)做為營建資訊的多面向分類策略，並以全分類碼將三維物件與慣用的資訊有系統地連結，似已達成自由資訊流的理想；然而在實務應用上，如何應用全分類碼連結資訊？尤其是在產業習慣與語彙不同的狀況下，代碼的使用是否仍能通暢無阻？則需要更多論述說明及驗證。本研究整理美國BIM標準中的營建資訊分類體系，分析三維物件與慣用資訊的代碼連結方式，並嘗試用全分類碼連結我國的公共工程技術資料庫，整理因地域性產業習慣與語彙不同問題，並提出解決辦法。研究的成果顯示，總分類碼中的表21元件碼、表22綱要碼、及表23產品碼的使用，除了將慣用資訊有效率地連結至BIM的物件外，也補足許多營建商品的資訊缺口，未來更不會有碼數不足的問題，改採用總分類碼是較佳的選擇。台灣地區已具綱要碼經驗，又有完善的公共工程技術及成本資料庫，與全分類碼連結的困難度不高，然公告的共756章綱要規範中，高達627章(＞80%)無法直接在第六碼補「0」而轉換為六碼綱要碼，也沒有一致的轉換規則可循，建議逐一依照規範的內涵給定適當的總分類碼以便與國際接軌。

The only way to compensate cost of implementing Building Information Modeling (BIM) is to leverage the information built in it. Since the proportion of the NBIMS-US, and using OmniClass codes to link objects of BIM with construction information, a real free flow of information has been accomplished. However, not much papers have practically describe how those codes could be used to link construction information with BIM objects and how to adjust language and regional differences. This particular study began with summarizing the strategy of classifying construction information and followed by analyzing the method of linking OmniClass codes with BIM objects in order to investigate the feasibility of using OmniClass codes in the Taiwanese Database of Public Construction (TDPC). The results have shown that use of OnmiClass Table 21, 22, and 23 could not only effectively link conventional construction information with BIM objects but also make up the product information gaps in construction industries. Among the current 756 chapters of specification in TDPC coded by using old five-code master format, 627 chapters (＞80%) could not transfer successfully to the new six-code master format by adding an zero. Neither a systematic transformation rule could be found. To feasibly link local information with BIM objects, the authors suggested replacing the old master format codes with OmniClass codes by identifying the content of every chapter of the current specifications in TDPC.
