Final bow in the Federal ribbon
The building is the final chord of the city planning guiding concept on the reorganisation of the government quarter. Marie-Elisabeth-Lüders-Haus is a project of superlatives: Each of the seven upper floors is as large as a football field. The reinforced concrete colossus is made from 4.000 tonnes of steel and 40.000 m3 of concrete; the shell alone weighs more than four times the Titanic. It is based on approximately 1.000 plans and 15.000 pages of statics – the purpose of which was to depict the construction work in a way that most closely matched reality, here literally down to the millimetre.
KREBS+KIEFER was commissioned with the technical general planning for the extension, which connects to the former eastern façade of the existing building and extends to Luisenstraße. The eye-catcher of the new building is its tower, rising to almost 40 m, and the impressive main entrance with its 22 m high rotunda on the interior. Equally noteworthy: The finished load-bearing structure was lowered using 32 hydraulic presses in order to deliver the load to the existing building in a controlled way.
