Despite studies exploring potential applications of unmanned aerial systems (UASs), the particular use and value of visual assets (photographs or video) collected with UASs for construction management tasks is not well understood. This paper presents an exploratory case study to identify potential applications of visual assets obtained from UASs for construction management tasks. The case study involved the development of a visual assets database from UAS-based images and videos collected during UAS flights at jobsites in the United States and Brazil as well as semi-structured interviews with construction project personnel. The results revealed potential applications of UASs mainly for project progress monitoring, job site logistics, evaluating safety conditions, and quality inspections among other secondary management tasks. In addition, an analysis of costs related to the use of UASs was performed. The main contribution of this case study is a better understanding of the use of UASs for construction management tasks and their regulatory and cost implications.
