Abstract
There is a requirement for improvement in the productivity of curtain wall installation owing to the shorter duration of the structural work cycle in the construction of high-rise buildings. The literature on the cyclic operation network (CYCLONE) modeling method provides methods to improve the productivity of curtain wall installation by evaluating the required additional commitment of resources using a sensitivity analysis. Therefore, there is a limit to how much the work process can be improved. The purpose of this study was to propose a methodology to improve the curtain wall installation process by transform the CYCLONE modeling method, which takes into consideration the duration and zone of the work task. Based on this method, we analyzed and improved the curtain wall installation processes and then compared the process productivity using a discrete event simulation tool. In order to verify the applicability of the field, the improved installation process was applied to the case of a high-rise building site. The results thus obtained were analyzed with the productivity of quantity per labor and installation costs per unit. As a result, it was found that the improved process simulation and the field data showed similar results.
