In principle, severe earthquakes are to be expected in the Basel region because in terms of plate tectonics, Germany and France are drifting apart along the Rhine Rift. In the event of a catastrophe, the Basel City Fire Service's main building is one of the crucial structures that must remain operational. With a 44 x 15 m footprint, this building was built in 1943 as a reinforced-concrete structure, without taking the risk of earthquakes into account.


The parking garage for the emergency vehicles is on the ground floor, with eleven doors in each of the two long facades, while the three upper floors accommodate offices, sleeping quarters, common rooms and other fire service rooms. The building's vertical loads are transferred by means of 24 concrete columns on the ground floor, where there are hardly any horizontal reinforcing elements.
