Technical Details

Fraport Regional Airports of Greece was established for the 40-year concession for the upgrade, maintenance, management and operation of 14 regional airports in Greece. The concession entails designing, developing, engineering, procuring, constructing, commissioning, maintaining, operating, managing, owning and financing the airports over the 40 years. As a first step, the concessionaire is required to undertake certain Imminent Refurbishment and Expansion Works under ongoing operation. The aforementioned works included and had as a main focus the passenger terminal and other secondary buildings. All construction works are to be executed under ongoing operation.

For the airport on the island of Kos (KGS) a new terminal building is required to address the surging tourist loads. The new terminal building, with a GFA of 24,000 m², occupies the place of the existing one. The new terminal can accommodate 1,650 passengers at peak hour and 2.6 million passengers annually. Furthermore, a new firefighting building is to replace the existing one, with increased capacity to cover the response times set.

Construction designed in phases under ongoing operation with gradual transfer of operations from existing to new terminal.
