We began our topographic survey activity as a preliminary to our design and verification activities; the ever increasing demand of the market for surveys in fields that are no longer classic, together with the technological evolution that has made complex measurements and scans possible in the past has naturally led us to specialise so as to be a reference, for example, for laser scans for exteriors and interiors, surveys with drones for structural inspections of bridges and for volume measurement of quarries and dumps, as well as detailed architectural surveys.
