BBI is given a face04.09.2009
Manfred Körtgen, BBI/Technical Director of Berlin Airports: “After three years of intensive building activity, most of the work on the new BBI has already been completed. All key technical facilities at the airport are on schedule. Now the focus is on the terminal and its two piers. The steelwork on the roof construction for the terminal is well under way and will be completed early next year. Then we can celebrate the topping-out ceremony in spring.”
Just under a year ago, in July 2008, the go-ahead was given to start building the BBI Terminal – a key milestone towards realising BBI. Much has happened since then: structural work on the 715-metre-long main pier is visibly progressing. Structural work on the future low-cost pier, the north pier, has already been completed, and work on the south pier is on schedule. Up to 900 construction workers and over 30 tower cranes were employed on the terminal building site in recent months. A total of 150,000 cubic metres of concrete and 28,000 tons of steel have so far been used for building, and over 800 drill-foundation piles with a circumference of 1.20 metres and up to 23 metres in length have been planted in the ground. These are particularly important for geothermal energy use, which is a fundamental part of the energy concept for the terminal: 326 drill-foundation piles are specifically intended for geothermal use.
By late August, the majority of the concrete work in the main hall of the terminal could be completed and work could commence on the steel construction for the terminal roof and on the steel and glass facade. A major logistical feat: the two caterpillar cranes, which are currently on the west side of the terminal lifting the first steel components, are so big that 60 trucks were needed to assemble just one caterpillar crane. Each of the steel components are now being assembled bit by bit on the terminal. The total weight of the steel components required for the future terminal roof is around 10,000 tons, the heaviest single component weighing 123 tons.
But not only the terminal, BBI’s centrepiece, is now clearly recognisable – concrete work on the aprons, taxiway systems and the new south runway is also well under way. Over 1.3 million square metres of concrete indicate where aircraft will eventually take off, land and park. The topping-out ceremony for the BBI Terminal is set for spring 2010. Starting in May 2011, the airport will be tested thoroughly in extensive trial runs. The first planes will land at the start of the 2011/2012 winter flight schedule on 30 October 2011.
