The Beja Airport is located southwest of Air Base nº. 11 of the Portuguese Air Force, whose functions were widened to include civil use. For this purpose, COBA conducted studies from the Master Plan phase, up to the Preliminary Design and Final Design, Environmental Impact Studies and the Environmental Monitoring during construction.

During these studies, the infrastructures of the civil terminal were defined, as well as their location.

The airplanes flying from/to this terminal shall use the Airbase runway.

The Civil Air Terminal design included the corresponding Operational Areas (Air Side) and the Urban Infrastructures (Ground Side).

The Air Side design included an apron for high-capacity aircrafts and a taxiway connecting this apron to the main runway of the Air Base.

The project involved the civil construction works (earthworks, paving and drainage) and the ground lighting and its control from the Air Base.

The Ground Side design included the overall earthworks and road lines, landscape integration, power distribution to the transformer stations, outside lighting, telecommunications infrastructures and gas network. The Ground Side infrastructures correspond to all the road accesses and parking lots for the buildings.
