Unlike production line works, construction work is non-repetitive in nature. In this study, a checklist was developed to characterize the ergonomic hazards of construction work. Eight existing checklists including OWAS, RULA, and REBA were integrated, and a new version was designed to include more postures of lower extremities. The analysis results obtained using the new checklist showed that manual materials handling (MMH) is the most common risk factor. About 62% of the MMH was done below the knee level or above the elbow level, and 22% was carried out with the trunk twisted more than $60^{circ}$. The next risk factors were the works done with the knee bent or squatted, or with the shoulders abducted. It can be concluded that the new checklist is successful as a quick and easy tool for screening risk factors of construction works, although it is not capable of determining action levels. Further studies on validation of the checklist are expected.
