The various parts of the program, the roadway roofing of the customs facility, the BVB infrastructure building and the customs clearance cabin are combined by a uniform design principle.
As the core element, the roadway roofing determines the construction and its characteristic expression. In a dialogue between supporting structure and architecture, a simple structural system is developed, which enables an efficient and cost-effective solution.
The selected frame structure consists of clamped steel columns and veneer laminated timber beams. The three-ply panels above connect the frames and form the roof surface. The cantilevered concrete roof of the customs building is cut back except for a small overhang and thus serves as a support for a new, lower-lying roof area, which connects the customs building with the roadway roofing. Once again, the roofs of the customs clearance cabin and the BVB infrastructure building are slightly lower and in line with the program. The only difference between the structures is the dimension of the beams due to the different spans. In order to provide the best possible field of view of the roadway, the passenger cabin extends beyond the existing edge of the customs building.
