Inspection d’ouvrage d’art par drone

Above, the two orthofacades of a 6mm GSD each for the detailed inspection of the two sides. Subsequently analyzed by a professional in building pathologies, orthophotos will make it possible to precisely locate some defects such as: slabs loosening, joint strips separations, cracks, infiltrations, rust traces and any other structural defects that can adversely affect the safety of the structure and its surroundings.

Orthophotos directly delivered to the design office in charge of the auscultation operations and safety reports project.
