RETTEW has been granted an exemption by the FAA for use of the firm’s drone (Unmanned Aircraft System) for surveying and mapping purposes. Though RETTEW has owned a drone for roughly a year, the firm was not authorized to use the system commercially until the FAA granted the exemption. RETTEW will now be able to use the drone for rooftop surveys, mapping of land areas, as well as inspections of bridges and pipelines.
