Current studies have focused on the exploration of the unmanned aircraft system (UAS) applications in the construction and infrastructure domains, such as progress monitoring, condition inspections, and particularly safety inspection. While their works have had significant contributions to highlighting the potential of the UAS technology, there are still gaps in the lack of operational considerations and workflows established to integrate the UAS into the current safety management program. To fill this gap, this study conducted field tests at commercial building construction worksite by adopting conceptually developed UAS flight protocol. A total of eight flights were performed to collect visual assets and provide for safety professionals at the jobsite with the insight of how this technology can be utilized in accordance with the developed workflow. A total of eight project personnel participated in the UAS flight test at their jobsite as well as post-flight interview to discuss how this technology can meet their safety management task goals. As the qualitative study, this paper narratively described the conceptual procedures consist of three different decision-making processes for ensuring the safe flight of the UAS: pre-flight, flight, and post-flight decision makings. Based on the potential users’ perceptions obtained during the field testing, this presented study focused on three different operational considerations: involving project-based, UAS’s capability and hardware specifications and UAS and project team-based aspects. The main goal of this study proposes a decision-driven workflow for UAS-integrated safety management that encourages sustainable and continuous improvement and documents the operational considerations related to this application. As the qualitative exploratory study, this research is limited to employ only one test-bed environment and the small number of interviewees. However, this study can contribute to a better understanding of the concerns, processes, and further recommendations to safely and effectively implement the UAS into the construction safety management program.
