Drones for bridge inspection research has been completed by MnDOT in multiple phases since 2015. As of summer, 2017, Phase III of this research began using the SenseFly Albris and the Flyability Elios, a collision-tolerant drone more suited to confined spaces such as box girders, culverts, or areas that are difficult to access. Due to the success of this research, MnDOT Metro District purchased the Elios drone to supplement bridge inspection access where space is confined and optimal lane closures are prohibited, which has been an on-going issue in the District due to traffic volumes. This project implements drone inspection for the metro bridge inventory and other similar representative structures by creating an inspection plan that identifies bridges best suited for drone use, what parameters govern drone use in bridge inspection, and how unmanned aircraft systems (UAS) can be integrated into standard inspection operations. The project explores relevant technology, including reality modeling software, drone hardware, artificial intelligence, and autonomous flights. This project also delivers the UAS Safety and Operation Manual specific to the Metro District.
