公共工程編碼系統與BIM結合於預算書製作之研究

Abstract

工程顧問公司或建築師在提供業主設計服務的過程中，需要替業主完成專案的預算書，而基於工程會的物價資訊統計上的需要，預算書的格式必須透過公共工程經費電腦估價系統(PCCES)平台來製作，但目前國內所採用PCCES製作預算書的流程與工程編碼編列方式將花費許多時間、大量人力且以人工進行工程編碼編列的錯誤率也較高。故本研究在這樣的前提之下嘗試使目前業界所採用的預算書製作流程更為自動化，縮短編碼所需時間、增加編碼編列的正確率以及提升行政院工程會於價格資料統計時的準確性。 本研究以「台灣大學土木研究大樓6-7樓裝修工程」作為案例，先運用建築資訊模型(BIM)進行工程項目數量的計算，再經由本研究所建立的公共工程編碼系統讀取，自動產生對應的工項編碼，最後再與PCCES作結合產生預算書。研究結果發現BIM運用於工程估價，可減少過去設計階段中以人為方式計算工程材料數量時所需的時間與錯誤率，且本研究所開發的程式也明顯縮減人為編碼所需的時間。整體而言，本研究中所提出的預算書建立流程，不僅讓工程編碼正確率顯著提升，預算書金額估算結果也無明顯差距，證實該項方式確實優於一般公共工程所採用預算書建立流程。

The current budget sheet creation process and engineering coding methods have high error rate and required much time and effort. The purpose of this study is to improve the traditional budget sheet production process, shorten the time required to encode, increase the coding accuracy. Study of “Interior Decoration project of the National Taiwan University Engineering College Building 6-7 floor renovation” as a case, the use of building information modeling (BIM) for the calculation of the number of projects, and then read by coding system that the study established to get the engineering code, and finally combined with PCCES to produce the budget sheet. The results showed that BIM used in the quantity of construction project can reduce the time-consuming of the amount of material calculate artificially and error rate in the past. Also, the program develops in this study was also significantly reduced the time required for artificial coding. Overall, the budget sheet creation process proposed by this study significantly improved the engineering coding accuracy, and the budget sheet estimated in current study was almost the same as the budget sheet estimated in normal process. The results confirmed the budget sheet production process proposed by this study was better than the traditional budget sheet production process in public construction.
