Background and Aim: Work-related Musculoskeletal Disorders (WMSDs) are the most prevalent occupational diseases and injuries. The aim of this investigation was WMSDs risk factors study in building construction industry by PATH (Posture, Activity, Tools and Handling) method.

Materials and Methods: This analytical-descriptive and cross-sectional study was conducted in four construction sites. A total of 3100 observations of 89 workers in 14 jobs were obtained. The percent of time determined for trunk, legs and hands postures, and manual material handling activities, used tools and handling in job tasks.

Results: Trunk, legs and hands postures, tools and objects weight differed significantly between stages (P<0.0001). Neutral trunk posture was observed frequently. Neutral legs and hands postures were observed greater than %50 and %80 of the time respectively in studied workers. Tools are used with different frequency in studied jobs. Loads with less than 5 Kg were handled repeatedly.

Conclusion: The result of this study can be used to reduce musculoskeletal disorders in construction workers. This study revealed construction workers spent more time with neutral postures. But ergonomic interventions should be accomplished in specified jobs.
