Physical Load Among Construction Workers and Analysis with Objective Ergonomics Research Method

There is growing number of work related musculoskeletal disorders among workers in construction industry. Employees in construction professions admit physical load and discomfort in various body parts after the work. Accordingly to Eurostat statistical data 60 % of total work related diseases are attributed to musculoskeletal disorders in Latvia. The aim of this study was to determine physical load of construction auxiliary workers and bricklayers using objective ergonomics research method HR monitoring and subjective ergonomic risk assessment methods. The research involved full time 8 auxiliary construction workers and 7 bricklayers. Analysis of the heart rate monitoring data proved that objective physical load analysis method is more precise than subjective workload evaluation methods. Results showed that construction workers workload falls into hard and moderate work heaviness category. More experienced workers with longer length of service were subjected to lower work heaviness category.
