Study on simulation technology to evaluate working time from bim data and mesh data

Abstract

Research on four-dimensional (4D) building information modeling (BIM) simulations has recently been actively conducted. However, the 4D BIM simulation often draws the installation order of the building parts. Therefore, only a few studies have analyzed the changes in working time owing to differences in the installation order of building parts. In this study, the effect of the difference in the installation order of the building parts on work time was investigated. After reproducing the construction site in the virtual space, an agent that shuttles between the stockyard and the installation location was created. This agent can move around and avoid newly installed members as construction progresses. Therefore, the total moving distance of the agent changes depending on the installation order of the building parts. Based on changes in the total moving distance, a method was devised for evaluating the goodness or badness of the installation order of building parts. Subsequently, the developed simulation system was applied to install studs on the partition walls. In addition, the simulation system was applied to new constructions and renovation works. When applying the system to renovation work, simulations were performed using mesh data created based on the point-cloud data of existing buildings
