Abstract

Labor productivity is a critical factor influencing the success of construction projects in terms of cost, quality, and schedule performance. This study aimed to evaluate labor productivity in reinforced concrete structural works, including reinforcement, formwork, and concreting, using the Work Sampling method. A quantitative observational approach was employed through random observations to classify workers' activities into three categories: Effective Work, Essential Contributory Work, and Idle Time. The observation data were analyzed using the Labor Utilization Rate (LUR) indicator to measure the efficiency of labor time utilization. The results showed that the project's average LUR was 55.50%, indicating satisfactory labor productivity as it exceeded the industry benchmark of 50%. Reinforcement work achieved the highest LUR of 62.10%, while concreting recorded the lowest LUR of 47.10% due to high Idle Time caused by delays in ready-mix concrete delivery, concrete pump interruptions, and inefficient material layout. These findings provide a basis for improving logistics management and work coordination to enhance productivity in reinforced concrete construction projects.
