3. Conclusions Kyiv TV tower diagnostics was conducted with application of the methods of non-destructive testing and remote diagnostics, using an unmanned aerial vehicle (UAV) and photogrammetry. This inspection allowed the construction of a 3D model of the object and localizing the defects on the structure. Critical defects, potentially hazardous for the object service, were detected during inspection. Obtained data were the base for developing recommendations on the object repair and restoration. The combination of traditional non-destructive testing methods with innovative remote diagnostics technologies allows greatly shortening the time for performance of the work on ensuring the safety and reliability of large-sized constructions.
