Deutsche Bank Twin Towers
The German bank skyscraper in the Westend of Frankfurt consists of two skyscrapers that are each 155 meters high. They are also referred to as debit and credit, twin towers or German Bank I and II. The Bank recruited at the time of substantial refurbishment with the term Green Towers. Because of their media presence, the twin towers are among the most famous buildings in Germany.
Architecture
The tower was built from 1979 to 1984 according to designs by Walter Hanig, Heinz Scheid and John Schmidt. It stands on the Taunus area close to the Old Opera House, at the beginning of the Mainzer Landstrasse and on the border of the city districts of Westend, city center and the train station area. The towers were originally planned as a hotel in the American hotel chain Hyatt. When the towers were acquired by Deutsche Bank, they were already under construction. Just before the main entrance are the entrances to the underground S-Bahn station Taunus system. To the south and east is the green area of the city walls, which offer dramatic views of the building; to the west, the high-rise axis Mainzer Landstrasse to close ( followed at a short distance the skyscrapers Trianon, Frankfurter Büro Center and Westend Straße 1 ). To the north stretches the founder temporally embossed Westend residential district, which is protected from further high-rise buildings.
The complex consists of three parts: a four- story base and the twin towers. The buildings are complete reinforced concrete structures with superior mirrored glass facades.
In contrast to the adjacent, a few years later built high-rise Trianon, the base structure of the German banking skyscraper fits little on to the found urban environment. It is lower than the neighboring buildings, but spreads over large footprint in the environment. From the center of the plant ( between two towers ) stretch on an irregular floor plan three components to the east, southwest and northwest. Both in the horizontal and in the vertical direction has the Fußbau several 45 ° - angle.
The two towers also have an irregular, but in both cases the same floor plan with many angles of 45 ° and are available in 13 m distance to the central to the resort arranged point-symmetrically.
The building has become a popular setting in the print media and television has become a symbol of the German economy, including on the one hand contributed the distinctive twin-tower configuration, on the other hand, also referred to the role of Deutsche Bank as the heart of the Germany AG, tight mutual interdependence German corporations.
In analogy to the twin towers of the World Trade Center destroyed in 2001 in New York, the building is also referred to as the " Twin Towers ", a term which could not prevail in public.
Construction
The two towers have a common 4660 m² large foundation plate which is 4 m thick in the middle and tapers to the edges to 2.5 m. The plate consists of 16,122 m³ of reinforced concrete. The foundation depth is approximately 13 m below ground level.
Renovation
In 2006 it was announced that the towers need to be rebuilt due to changes in fire regulations. On this occasion, the German bank the towers was fundamentally renovate after 22 years of use of 2007 to 2010. For the interior design, the bank chose a design by the Milanese architect Mario Bellini. The renovated building is certified under the American Standard Platinum LEED for existing buildings as well as after the German seal of approval DGNB. Following the reorganization of the energy consumption in half, water consumption by over 70 percent and CO2 emissions fell by almost 90 percent.
The German bank had its headquarters bought back in summer 2007 for 272 million euros from a fund her daughter DB Real Estate, to perform the upcoming general renovation on their own can. The Bank invested around 200 million euros in the modernization. The towers should be for around 600 million euros, sold to a closed- end real estate funds, which will be launched by the subsidiary DWS Investments and then leased back.
General contractor for the technical equipment of the Twin Towers was Imtech. According to reports from the Handelsblatt newspaper in February 2011, the manager of subcontractors were bribed, among others, brothel visits. These in turn were allowed to settle already work more hours in early 2010 in return. The company could be determined internally by the criminologist Thomas Wüppesahl 2011. The findings have not been implemented to the Imtech crisis of 2013.
