The construction project involves covering a petrol station with a mechanically prestressed membrane structure measuring approximately 32.00 m in length and 18.50 m in width, with a membrane edge height of approximately 6.50 m. The membrane area is approximately 330 m² to 415 m².

The geometry of the roof is formed by three asymmetrical funnels, which are connected in a linear sequence to form a free-form surface.

The roof is supported by three round tube columns, to which between 6 and 8 horizontal cantilever arms made of rectangular profiles are connected in a star shape. These arms are stabilised by diagonal suspensions made of rectangular profiles, which are connected to the column head.

Garland-shaped edge cables stretch between the tips of the cantilevers and are guided through the edge cable pockets of the membrane, tensioning the membrane at the edges. The lowest points of the funnels are created using steel rings that close around the supports and to which the membrane is clamped using a piping connection with steel plates. To stabilise the membrane surface against wind suction loads, throat cables are provided in the seam areas between the funnel modules, as well as supporting radial cables, which are tensioned in the membrane plane from the lowest points to the tips of the cantilevers. To limit membrane deformation due to snow loads, these suction cables are connected to the cantilever arms with suspension cables.

The petrol stations are located in Pfullendorf, Hamburg, Osnabrück, Stuhr, Sundern, Kirchheimbolanden, Memmelsdorf, Rostock and Friedrichshafen.
