Abstract [en]

The use of ergonomic production methods in concrete casting does have a significant human, social and financial impact in terms of the reduction of occupational injuries and related injury compensations. This paper presents a case study of comparative analyses of the ergonomic situations for concrete workers casting with two different types of concrete, namely the conventional concrete and the self-compacting concrete (SCC). Analyses were conducted with two methods for the identification of ergonomic hazards; and in comparison to conventional concrete, the analysis results have shown that SCC consistently gave significant improvements in work postures and led to less workload and noise exposure among concrete workers. The combination of lean thinking and ergonomics result in a system where  the worker is as efficient, safe, and comfortable as possible during the concrete casting work process. Material handling plays a significant role in lean construction by keeping the worker at the center and ameliorating many of the ergonomic problems that would otherwise remove the person from the production process. Transportation and unnecessary motion are two of the seven types of wastes that can be significantly reduced with the implementation of an ergonomic production system such as SCC that eliminates awkward work postures and vibrating tools. With the correct ergonomic material/product used in production of concrete structures, waste can be removed from the production system, thus creating an increase in production, decreased costs, an increase in quality of the product and less absence of workers in the future due to less stressful work.
