The Momeni Group acquired the Hamburg headquarters of the Axel Springer publishing house in 2015, in order to create a premium property with offices, retail, dining and living space in the Springer Quartier. Internationally renowned architects Gerkan, Marg and Partner took on the challenge of energetically renovating the Springer high-rise office block, which has been listed since 1997, and of expanding it into a modern, new, urban building. To achieve prospective certification to LEED Gold and to be able to cope with the particular structural design demands, using our Cobiax SL void formers was planned in at the structural design phase by WTM Engineers Hamburg. As a result, it was possible for the main construction contractors Ed. Züblin AG, as general contractors, to reduce the amount of concrete needed for the new wing by 496 m3, and to achieve weight savings of 12,400 kN.
The new building‘s inner city location and the various uses for the ground and basement levels, compared to the uniformly designed upper floors, presented a challenge for the architect and structural engineer. In order to include all suggestions, the structural design experts at WTM Engineers Hamburg proposed using our Cobiax SL modules, which had already met with success on other projects. The positive influence on the building‘s structural design provides unimagined opportunities in the design of further rooms: on the one hand through shallower slab depths and on the other through spans of up to 20 m.
These advantages could be fully exploited in the SPRINGER QUARTIER, as various areas of the building could not have direct foundations, complicated foundation issues arose at the property boundaries and the different uses on some in the time planning. We pre-assembled the systems in the first delivery ourselves at the factory, so the concreting work could start straight away. For the remaining six, the individual components were assembled and processed on site instead. On the first day using the SL modules, we trained all the workers on site to ensure quick and easy assembly. For the laying itself, plans were made where the slab surfaces were covered in void formers. We created these, taking into account the structural design calculati
