Use of Unmanned Aircraft Systems for Bridge Inspections

The Minnesota Department of Transportation and Collins Engineers have been researching the use of unmanned aircraft systems (UASs) as a tool for bridge inspections. Phase 1 of an implementation study has been completed, and a Phase 2 study is nearing completion. Phase 3 of the research effort will start early in 2017. These research studies are looking at current FAA regulations and evaluating the advantages and challenges of using UASs for bridge inspections; the results are promising. The research has tested different types of UASs on eight bridges of varying configuration, size, location, and condition to determine the effectiveness of UASs as a tool to supplement bridge inspections.
