HIGHLIGHT OF THE PALAIS QUARTIER IN THE HEART OF FRANKFURT AM MAIN

A sensational large construction project was realised in the inner city of Frankfurt am Main under the title of „Palais Quartier“ at the corner of Große Eschenheimer Straße / Zeil. Four buildings arose on an  area of approx. 17400m²: A multi-storey hotel, the MyZeil shopping centre, the Thurn und Taxis Palais, a baroque city palace which was reconstructed during the building measures according to historical example, and the 34 storey office skyscraper „Nextower“.  The 135m high office tower has a subterranean garage reaching almost 23m under the ground. To ensure an efficient construction process despite the surrounding buildings and the immense depth, the underground levels were built using the dig-and-cast construction method.

A worried phone call from a neighbour to the client caused great exhilaration in the entire project team. The client should rush to the building site because all the facade columns were crooked…

CONSTRUCTION SITE MANAGEMENT

The skyscraper is braced by two reinforced concrete cores that are coupled by steel girders. The sculpture-like outer shape results from the inclination of the edge columns close to the facade, the deviation forces of which are equilibrated by the concrete slabs.  A structural challenge was posed by the fact that a part of the building with 28 stories cantilevering 15 m had to be suspended or propped. The solution was an arrangement of inclined columns which interact with the slabs to form a truss.
