Abstract [en]

With the increasing industrialisation of the construction process in Sweden, the intensity and the nature of production activities are changing due the application of cost-effective and time-saving industrialised production methods such as off-site prefabrication and on-site assembly. However, the impact of these new production methods on safety and health of the worker has not been methodically investigated and is often assumed to be positive for the construction workplace. In this paper, the workload associated with the assembly/building of inner walls was analysed in terms of workers musculoskeletal system loading. The goal of the study reported here was to identify how the assembling of prefabricated gips walls affects the musculoskeletal system of construction workers.The methods used in the study are the QEC system (Quick Exposure Check for work-related musculoskeletal risks) and ErgoSAM which is a method that identifies situations of high workload and risk for musculoskeletal injury. The results obtained using QEC analysis showed that the inner walls assembly work cycle does entail some physically demanding work tasks, namely the lifting of gips wall elements which was found to have high exposure levels; drilling holes into concrete floors and ceilings and attaching (with screws) wall elements to the concrete floor and ceiling were found to have low exposure levels when these work tasks are not performed at a high pace. ErgoSAM analysis results have indicated at what time of the work cycle, what work posture and work tasks are risky to the workers musculoskeletal system. The use of both methods to analyse the impact of a new industrialised system has a lot of potential in identifying health risks and thus having a basis on which these risks can be planed out in the design of an effective and healthy construction workplace.
