The external plastering has a high rate of work accidents and corresponds to a large part of work-related musculoskeletal disorders (WMSD) in construction. The objective of this research was to statistically correlate the RULA and OCRA Checklist ergonomic risk methods, used in external workstations on building facades. The methodological approach consisted of a quantitative and qualitative research, including literature review and field research, including 32 employees, with the project approved by the Institution’s Ethics and Research Committee. This research showed results that indicate the high physical requirements that the activity exerts on workers, a strong and significant statistical correlation between the methods, and that the OCRA checklist method is the best option among those for the ergonomic evaluation. The research showed limitations regarding the amount of ergonomic methods used as well as the difficult access to construction sites. The research leaves the possibility of future studies on the statistical comparison between other ergonomic methods, using a greater number of statistical tools, in addition to analyzing other activities that make up the execution of building work in civil construction.
