摘要: 土木工程業中,工程造價與工期兩者一向為業主首要關切之議題,如何讓工程造價更準確、工期更短是為業界以及學術界共同探討之課題。首先有關造價部份,本研究利用結構體鋼筋、混凝土、模板費用,結構體材料與樓地板面積比例,以及結構體費用佔整體工程費用之比例,建立一種簡易方式用來預測鋼筋混凝土構造建築工程造價。依據此一模式所推估之造價,經與主計處98∼100年度編列標準比較,其誤差值約為0.9~7.4%,精確度落在估價類型中概估與細估當中,可提供工程人員一個簡易方式用來掌握工程總價之趨勢。其次有關工期部分,本研究利用模板及鋼筋細部分項比例,出工數及施作數量之迴歸方程式、結構細部分項生產力等資料建立一工期推估模式,經案例驗證初步可行。
In civil engineering industries, project cost and duration both are the most interesting topics for the owner. In this study, the unit price of steel, concrete and formwork, the ratio between structure material number and floor area, and the ratio between structure cost and total project cost are used to establish a simple model to predict the unit price of reinforced concrete building. The unit price estimated by this model is compared with the unit price of reinforced concrete building issued by DGBAS from year 2009 to 2011. The results show that the error is about 0.9 to 7.4%, which is a kind of accuracy between the cursory and detailed estimation. Therefore, this simple model can provide an easy way to trace the trend of construction price. A model about the duration in structure construction phase is also proposed in this study. The formwork and steel ration in different parts of structure, the regression equations between the labor number and construction number, and the productivity in different parts of structure are used to establish the duration model. Two cases are verified and show that the duration model is feasible.
