The authors have been developing methods capable of deducing the Synchronized Multi-Site Scheduling using the interface matrix obtained from the relationship between preceding and following of the tasks for the construction work with a repetitive nature. In this study, several structural construction plans were estimated by carrying out simulations using the construction delivery time (which are the criteria for the structural construction method plans) as objective variables. In this study, the Synchronized Multi-Site Scheduling method is in conjunction with the quantity information of the 3D model. Redefine the 3D model for using the technique of dividing and combining the 3D model utilized in the construction simulations. Various simulations created by the 3D model are redefined with reference to the productivity data and unit price information. In concrete terms, the performance of each structural construction method plan was estimated by carrying out a four-process simulation for the skeleton construction work above the ground for a high-rise RC office building using a site division and a component division as variables.
