Airport buildings incorporate structures with particularly strict specifications in terms of security, sound insulation, uninterruptible operation, as well as special mechanical installations. The New Doha International Airport incorporates pioneering construction methods that have been applied in the “Aircraft Maintenance Hangar”, the “Maintenance Facility Building”, the “Motor Transport Workshop”, the “Cargo Complex” and the “Airport Back-up Approach and Training Center”. In addition, the close involvement in the construction of Athens International Airport "Eleftherios Venizelos" and the new Ioannina National Airport, make Aktor a qualified stakeholder, in this particular field of construction.
