영향변수에 따른 수량변화 분석을 이용한 기본설계단계의 개산견적 모델 개발 = Development of Cost Estimating Model Using Quantity Variation Analysis by Influence Variables for the Schematic Design Phase

다국어 초록 (Multilingual Abstract)

The purpose of this research is to develop a conceptual model and prototype that establishes a new approach for building cost estimating in the schematic design phage. This research use the method that analyzes quantity and unit price separately to enhance schematic cost estimating through conducting literature review andi analyzing existing schematic cost estimating methods. In addition, this study proposes tile concept of cost breakdown structure including two more classifications: building element and floor compared to existing one only classified by trade. Thus, a Quantity Based Active Schematic cost Estimating(Q-BASE) model is developed founded on those two concepts. By applying proposed schematic cost estimating model, historical structure cost of residential complex building project is analyzed, and then, based on this analysis, prototype is implemented.
