Discrete event simulation has been widely used in construction operation modeling and analysis to measure and improve productivity of construction methods. However, the method has not been applied to Curtain-wall operation which cover 10~15 percent of entire project cost in tall building construction. It is crucial for a project manager to predict the productivity of curtain-wall operation alternatives. To secure the competitive standing in international tall building construction market, it is important to find the best construction operation alternative obtainable from optimum resource combination. Curtain-wall operation model using simulation is proposed to maximize the productivity of curtain-wall operation incorporating with the sensitivity analysis. A case study is presented to demonstrate the validity of the model. using Micro-Cyclone, the optimum resource combinations was found in two different perspectives, that is the cost and duration using sensitivity analysis. This study contributes to improve the productivity of curtain-wall operation by finding suitable resource combination at job-site.
