Abstract:
Delays in construction projects are inherent. Utilizing the experience from past construction projects can be helpful in predicting the delay in construction projects. Case-based reasoning (CBR), a technique that uses knowledge from past experiences, can be viewed as an effective method in estimating the construction delay. Even though CBR has been frequently used to predict the construction project costs in previous studies, studies performed for construction schedule and delay are rare. Moreover, the recent increase in the construction in Indian real estate industry shows a rise in residential high-rise construction. With emphasis on residential high-rise construction and using preliminary project information, this paper focuses on developing a methodology for predicting construction delay using CBR with the attribute weights being input from multiple regression analysis (MRA). The results indicate that the as compared to conventional multiple regression methods, CBR performed better in forecasting the construction delay. Though this study focusses on residential high-rise construction, the construction industry may be benefitted using the learnings from this study. It can prove to be useful for the construction professionals not familiar with the challenges existing in new locations. Consequently, this study can provide means of predicting the construction schedule in construction projects using preliminary project information
