A Major Project of International Importance: Berlin-Brandenburg International Airport
In the near future, air traffic capacity in and around Berlin will be considerably increased: Berlin-Schoenefeld Airport is being expanded by approximately 970 ha to a total area of 1.470 ha in order to create the new Berlin-Brandenburg International airport (BBI).
Once completed, the modern international facility located south of Germany’s capital will accommodate all of Berlin’s air traffic. Closure of Tempelhof Airport will be followed by closure of the inner city airport Tegel. The closure of both airports will permanently eliminate the problem of aircraft noise that has long impacted hundreds of thousands of city residents.
The current airport system, which originated at the time of Berlin’s historical division, is no longer able to accommodate increasing passenger volume and spreads over a greater surface than the new BBI airport. In addition, as a result of specially adapted airport infrastructure, wide-bodied aircraft will be able to take off and land in Berlin.
During construction of the modern airport, energy efficiency and regenerative energy systems are of particular importance. BBI will have an initial capacity of 22 to 25 million passengers. It can, however, be expanded to accommodate 40 to 45 million passengers, and will therefore be able to cope with projected increases in future air traffic.
The new airport will include a modern railway network providing fast connections to Berlin’s city center. The connection of the tracks for long-distance and suburban trains to the modern airport’s railway station requires an approximately 3.1 km long tunnel, several bridges as well as a 2.5 km long depressed exit and entry structure which will accommodate the tracks for the airport express. Excavations for the construction of the depressed structure were achieved by using the open-cut method.
DSI Haan supplied DYWIDAG Form Tie Systems for the construction of the depressed exit and entry structure. DSI supplied approximately 5,000 Ø 26.5 mm double anchors as well as approximately 4,000 Form Tie systems with Type N water stops. Additionally, the project required the use of steel-plastic cones in diameters of 26.5 mm and 20 mm.
DSI is pleased to have contributed to this forward-looking large scale project.
