Abstract This research assesses the effectiveness of unmanned aircraft systems (UAS) and provides further implications and recommendations for UAS-based visual inspections in the construction and infrastructure environment. This study includes field tests at infrastructure projects provided by Georgia DOT, as well as semi-structured interviews and survey questionnaires after the field tests. A total of three field test locations were selected, including an airport, bridge, and road. During the field tests, eight UAS platforms were used to collect various data, including still images, infrared images, and video. Interviews with and a survey of industry professionals participating in the field tests were employed to measure the effectiveness of UAS integration into their construction-related task environments. The results of this study will assist in implementing UAS in infrastructure construction and operations. Since only a small number of potential UAS users from the field tests and posttest interviews, this study qualitatively describes further implications based on users’ perceptions, prompting the integration of UAS into the domain of infrastructure construction and operation.

Introduction Infrastructure projects managed by the Department of Transportation (DOT) require systematic inspection and monitoring if they are to safely deliver completed products to the community. During the operation phase of the constructed civil infrastructure facilities such as roads, bridges, and airports, they also require maintenance services to provide safe and effective operations to the public. The management plans during construction and maintenance should be established periodically, systematically, and efficiently to * Sungjin Kim [email protected] Javier Irizarry [email protected] 1

maintain the long-term lifespan of the infrastructure project. In the USA, the DOT is responsible for the construction, operation, and maintenance of civil infrastructure facilities. They contract with third-party management companies or conduct self-management of their respective infrastructure projects. The current approach is for one or more project engineers or inspectors to use a manual approach to the tasks in the infrastructure project environments. The manual approach consists of four steps: (1) accessing the site, (2) collecting the inspection data, (
