The study is aimed at better planning the cycle process that considers production characteristics in high-rise RC building construction and at establishing a better method by a simulation system using computer-aided tools. A special emphasis of this study is placed on examining the effect for shortening the cycle term of site works and the influence from overtime work on the productivity where situation of such real projects is taken into consideration. Furthermore, we examine choices of optimal working patterns even considering some additional labor cost generated by overtime work.
