The implementation of construction projects always has the risk of work accidents. Improper execution of occupational health and safety can lead to various risks of work accidents. Therefore, it is necessary to research risk analysis and mitigation control to reduce the risk of work accidents. This study aims to determine the domi-nant risks related to Occupational Safety and Health (OSH) during the Corona Virus Disease 2019 pandemic. The method used in this study is Bowtie Analysis because this method can assess risk and maximize the mitigation of the causal factors and their impacts. The results showed five dominant risks caused by 20 causal factors and 14 effects of work accident risk. The chief risks include broken sling cranes, overturned cranes, workers falling during scaffolding installation, workers falling during painting, and workers falling from elevators. Meanwhile, the risk due to the COVID-19 pandemic almost did not affect the dominant risk of work-related accidents. The risk response resulting from this study contains 36 alternative mitigations to prevent and resolve risks.
