The project consisted in the design of five control towers for the Airports of Algiers, Oran, Constantine, Ghardaïa and Tamanrasset in Algeria. All of the towers were designed with cast in place concrete structures using the structure as an expressive element in the design of the tower. Each tower has a unique design that adapts to the specific conditions of site, climate and surrounding vernacular while at the same time creating and icon for the airport.
The tower for the Algiers Airport is the tallest with a total height of 72 meters. The fluted shaft made up of 12 radial concrete ribs provides the required resistance for the high seismic risk of Algiers and becomes a dominating element in the design of the tower. At the top of the shaft the ribs open slightly to support the upper levels and control cab, at ground level they extend like roots giving addition support to the tower and creating a large base building for the administrative elements of the program.
