Abstract:

Musculoskeletal disorders (MSDs) are a significant issue in the construction industry, which continues to rely heavily on manual labor. On-site tasks involve heavy lifting, prolonged awkward postures, and long working hours?factors that heighten the risk of developing MSDs. The workforce plays a crucial role in project progress and quality; however, worker absenteeism due to these disorders affects productivity, leads to knowledge loss, and requires additional time for training and adaptation of new workers. Semi-continuous video recordings, task descriptions (including workload, timing, and sequencing), and postural analysis using the Rapid Upper Limb Assessment (RULA) method are utilized to evaluate the physical risks associated with these tasks. Based on the findings, improvement proposals will be developed, addressing organizational, physical, and environmental factors to optimize working conditions while ensuring performance and worker well-being.
