Abstract
The operation of formwork has significant effects on the total structural construction cost and duration. Therefore, It's important to select proper formwork method in the planning phase. Especially in the residential-commercial building, as the customers' demands for various floor shapes and stories are getting higher, selecting formwork method is getting harder. The existing researches are focused only on the considerations for selecting formwork method or the decision support model for slab formwork. In this study, we developed a decision support model for the selection of exterior wall formwork in commercial residential building construction. The purpose of this model is to help the decision maker select the most suitable formwork method, which reflects various site conditions by using Delphi method. The type of formwork methods we considered are Gang Form, A.C.S, G.C.S, and R.C.S that are well used in these days. This proposed model is expected to increase the efficiency of whole construction project by selecting optimal method.
