Merkur City Offices
The Merkur City Offices in Graz set standards in modern office construction and combine innovative architecture with sustainable construction methods. The project uses the timber-concrete composite system to meet high structural requirements and simultaneously optimise the environmental balance. Of particular interest to technicians and structural engineers is the optimised load transfer through the hybrid construction, which maximises both the compressive strength of the concrete and the tensile strength of the timber. This construction method enables flexible room concepts and a reduced construction time.
The relocation of the Merkur Versicherung Generaldirektion to the new Merkur Campus in 2020 freed up the previously used building in the heart of Graz city centre and was to be converted for a new use.
The building had grown together over the centuries from three individual buildings and was now to be thoroughly renovated and modernised. Some of the existing buildings had wooden ceilings on the inside, which made it possible to renovate them using the wood-concrete composite system.
In the Merkur City Offices, a modern and functional office solution was created on a total area of 10,000 m² over six storeys, which on the one hand preserved the appearance of the historic building from the Wilhelminian period and at the same time realised an extension of the area by adding storeys to the existing building. Thanks to the timber-concrete composite system, the weight of the individual storeys could be reduced compared to a pure concrete ceiling, which facilitated the necessary structural verification for the extension.
Schmid Schrauben Hainfeld was able to support this project with approx. 35,000 RAPID® T-Con screws for wood-concrete-composite systems and the pre-calculation using the Schmid calculation tool.
