Vienna Centre: Sophisticated precast concrete products from Reiter

published 02/2013

Everyone is currently talking about the new complex of buildings in the middle of Vienna. The concept shapes the cityscape for the future and Rauter is the mastermind of these essential forming elements of this project. The respective concrete parts are more than a mere eyecatcher.

It has been re-opened recently but has already been supplied with precast concrete products since 2009: WIEN MITTE is more and more gaining form thanks to the flamboyant precast concrete bearers and columns.

Especially the individual parts of the façade, the columns and cornice on the ground floor provide an optical support of the glass façade above. An original detail on the side: the façade elements with a weight of up to 8 tons were erected underneath the already existing façade!

Three ellipses

Another technical challenge within the façade: The three ellipses with concrete framed window elements consist of 20 precast concrete parts each that had to be planned with precision in 3D, realized and built in. The challenge was definitely the complex formwork geometry and the erection of the precast parts as the ellipse is conically tilted and double-curved. Today you can admire the perfect collaboration of these processes on site.

Ceiling design by Esther Stocker

The ceiling in the entrance hall of the building complex was designed by the artist Esther Stocker.  As the media described it: Backlit columns made of frosted glass facing Landstrasse and a tilted ceiling made of exposed concrete designed by the artist Esther Stocker gives it a touch of Las Vegas. As a matter of fact, these concrete elements are one of the major innovations. Ulfried Kogelnig and his Rauter team were the masterminds of this project development and solution finding process. (Together with the Halfen company), the mounting components were newly developed especially for this application. Furthermore, the ceiling meets all fire protection requirements. For the successful implementation of this piece of art, it was also necessary to develop new mounting tools.
