This study proposed TACT based optimization model for improving work continuity in apartment structural work. The model was developed by focusing on three key as follows; First, the proposed model allows work crews to effectively rotate tasks to maximize the labor productivity. Second, the proposed model makes a plan for an efficient way to repeatedly carry out the same tasks by standardizing smaller TACT processes. Third, The proposed model suggests a multi-dimensional way to look at a frame construction process to comprehensively reflect characteristics of the construction site such as the combination of work crew and labor productivity, the calculation of the number of workers and equipments that are suitable to carry repetitive works. Through case study, the proposed model showed productivity increase of 25%, non-working days and half-working days decrease of 5 and 4 days, respectively, compared to 6 day cycle. The proposed model would help contractors to achieve successful completion of projects by establishing practical plans with improved work continuity and productivity.
