Objective: To evaluate the ergonomic risk in civil construction workers.

Materials and methods: A descriptive, non-experimental, cross-sectional study was carried out. Thirty-three civil construction workers participated in the study, all of them field personnel. Data collection was carried out through the application of a questionnaire for the identification of ergonomic risk referred to occupational factors, using the REBA and OWAS methods in the Ergonautas software.

Results: Of the sample, 66% (n=22) of participants showed medium risk exposure. Likewise, the REBA method reveals that the trunk and arms obtained scores of 3, considered high. In the formwork task, the highest ergonomic risk was evidenced. The OWAS method indicates that the back and legs present higher scores, being the sidewalk finishing and formwork tasks where dysergonomic postures prevail.

Conclusions: Construction workers are exposed to medium risk levels, compromising the upper and lower body region, suffering in the future from musculoskeletal pain. It is recommended to establish an ergonomics program that promotes the prevention of the development of musculoskeletal problems.
