BMW Industrial Building TKB, Munich

At BMW’s main plant in Munich, a new three-storey production building was constructed on the site of an existing production hall. The building, which is approximately 200 metres long, is used for the highly automated production of car bodies. The structural framework consists of reinforced concrete slabs on composite beams; the columns are designed as prestressed precast columns in immediate bond. All non-load-bearing walls, such as those for shafts, stairwells and the façade, were constructed from solid precast elements. These are connected to one another via elastomeric bearings, dowels, bolted connections, and grouted joints. The cores, which provide access to the roof level, reach heights of up to 23 m with this construction method.
On the ground floor, there is a logistics terminal for unloading trucks. This has a column-free width of 19 m, which necessitated the use of large-format composite support beams to carry the load of the building columns above, including the roof structure. In the area of the entrance to the logistics terminal, three façade columns on the ground floor had to be omitted. Their loads are supported by a large-span composite suspension system with a span of 23 m.
In order to complete the construction swiftly in confined spaces, all components – with the exception of the foundations and bracing walls – were delivered as prefabricated steel or concrete elements.
