Karlsdorf’s New Fire Station

A new fire station was built in Karlsdorf-Neuthard, with Werner Sobek was responsible for the structural engineering.

The building has a trapezoidal footprint with a width of 29 m and a length of 59 and 77 m, respectively, and consists of two different building volumes – a low-heated vehicle hall and the operational rooms.

High Earthquake Resistance

A special feature of the project is that the shear forces due to earthquakes are transmitted to the reinforced concrete cores through a cross-laminated timber slab that is only 6 cm thick. In addition, high ceiling loads are safely transferred via a wall-like beam made of cross laminated timber.

The solid construction walls were to meet exposed concrete requirements, while also helping to minimize the building’s grey emissions. For this reason, “EcoCrete R” concrete was used, a material with a recycled content of around 10 %.
