The purpose of this study is using a TACT planning and scheduling for apartment houses construction that have many of same units. Because using a TACT planning and scheduling is concluded time reduction at same units as apartment plan. The main contents of this study are 1) window and door work through the field study, 2) adjust worker assignment to minimize work time variation, and 3) an effect of working time through a case study. As a result, the total working time can be improved $21.2\%$ by using the TACT planning and scheduling. The stu요 recommends that 1) establish an accurate data between work period and resource, and 2) preparation to measures minimization of waiting time before using a TACT planning and scheduling.

The purpose of this study is to suggest a improved tact planning and scheduling by reliable Toning of work area in high-rise building construction. To do this, the characteristics of main work including electric & mechanical work were considered through the interview with field work forces. The content of the study is focused mainly on reliable work flow and rhythmical repetition of uniform resource quantity to manage effective tact planning & scheduling. And also the study recommends more implement of tact planning and scheduling to manage human resources successfully in repetitive building construction.

Poor usage of work-continuity for planning and management is one of the leading causes of decreased productivity in high-rise and complexity construction projects. For efficient finish work, tact scheduling method needs to be implemented according to tact time. But there are the studies about zoning of work area, daily construction information and tact planning and management, there are not the studies about tact time yet. The purpose of this study is to help implementation of tact scheduling by tact time and adjusted work-plan. The main contents of this study are as follow; (1)Tact time has been calculated as coordination of work-plan between a general contractor and specialties. (2)Project-plan can be without delay by tact time calculation method.
