| Abstract |
The purpose of this study is to propose the cost estimation system using case-based reasoning technique at the early project stage. To predict construction cost is difficult because of the lack of information about project at the early project stage and the complex interrelationships between many factors of influencing the construction cost. Case-based reasoning means using old experience to solve new problems. In this study, the used old experience is the direct cost of 530 apartment buildings, constructed from 1997 to 2001; the additional 10 cases are used for testing. The accuracy rate of predicting construction cost is compared using the CBR system with using regression analysis for verifying the CBR system. The prediction error rate of 4.74% in CBR system and 9.80% in regression analysis are obtained. This study conclude that utilizing the case-based reasoning??for predicting construction cost in construction project is possible |
