| Abstract |
Modular construction is a construction method with the production work in factory and the installation work in field. Especially the lifting work is a large part that requires for the installation of modular units in the field work. The exact lifting work forecast in the initial phase of the project lead to calculate the optimum construction period and cost. However, existing lifting equipment selection is performed on the intuition and the experience. So, there is a need for the objective and logical lifting equipment selection tool. In this study, proposed a model that can be the selection of the optimum of the tower crane through the relationship of three variables(tower crane, installation module unit, transport trailer) that affect the lifting work. It was possible to determine the amount of appropriate levels of tower crane according to the optimum position selection of tower crane and transport trailer. In the future, used in a modular building project to sharing information between the designers and builders in the early stage of the project, can help make the optimum lifting plan. |
