Methodology of ergonomic evaluation in construction and building works

Abstract: This work proposes a practical methodology for the evaluation and control of ergonomic risks in construction and building works. The methodology starts with the Analysis of Working Conditions for Risk Identification, and then selects the critical positions using techniques such as the hierarchical analytical method or the criteria comparison matrix. The next step is to determine the ergonomic tools to be used per workstation, and once the evaluations are completed, the results of the risk level and the recommended actions are considered as a basis for improvement proposals. Of particular importance at this stage is the use of the Ruler tool for angle measurement. The improved positions are re-evaluated to verify the favorable changes from an ergonomic point of view and, in addition, risk level values are compared before and after the implementation of proposals. Finally, the methodology includes an implementation plan and an economic evaluation, to decide whether it is appropriate to invest in ergonomic improvements. Improvements are observed in accident indicators related to the presence of ergonomic risks, while evaluating the opportunity cost related to potential savings for the organization related to absenteeism, staff turnover, costs related to medical breaks and potential fines for non-compliance with legal regulations. Finally, it is concluded that there is a potential profitability and feasibility of the ergonomic interventions applied and proposed.
