Lean Location-based Scheduling for High-Rise Building Project

Abstract

This paper presents a Lean Location-Base Scheduling for high-rise construction projects. The objective is to develop a work schedule format that is consistent with the job characteristics and working behavior of Thai construction workers. Based on the principle of analyzing critical activities together with the time-cost optimization. Under the allocation of labor groups to have the same working duration in each work group. Post-tension system of Condominium buildings were used in the study. The activities are divided into 20 activities, each sub-activity can be divided into work groups and labor groups according to the nature of repetitive construction. Setting the duration of work groups are 4 days, 5 days, 6 days, 7 days and 8 days per floor. It was found that the optimal duration and cost was 5 days per floor (Divide the activities into 5 workgroups, each work group takes 1 day). Direct cost are 114,844 baht and indirect cost are 138,250 baht, including total cost are 253,094 baht. Show that the Lean Location-Base Scheduling suitable for the construction of repetitive buildings.
