The building spans the 60 m wide dry dock of a former shipyard at a height of 15 m. The main floors are accessible by 4 different stairwells and elevators. Parking spaces, archives and the technical installations are located in the supports. The main structure of the building consists of 2 steel trusses of 10 m high and 100 m long. The central span is 72 m, the northern and southern cantilever are respectively 17,4 m and 19,4 m. Both trusses are supported by steel hollow section columns of 100 by 60 cm founded on piles. The horizontal stability of the building is ensured by the concrete cores built around the steel columns. Thorough BIM coordination prevented clashes during the execution and shortened construction time.
