Architectural Work Planning for Repetitive Activities Using the Repetitive Scheduling Method (RSM)

Abstract

This study provides a planning guideline for architectural construction with repetitive activities. Data were collected from a 44-story office building project focusing on bathroom wall construction, corridor plastering, floor leveling, and ceiling framing. The analysis of labor cost and duration revealed that the Critical Path Method (CPM) was ineffective due to sequencing and waiting time constraints. Therefore, the Repetitive Scheduling Method (RSM) was applied, resulting in an 18% improvement and a 32-day reduction in construction time. Labor costs for subcontractors were reduced by 69%, increasing their profit. Continued use of RSM and minimized waiting times can improve cost control for main contractors. This approach is adaptable for similar construction projects, promoting sustainable project management.
