The roof geometry can be described as a free-form derived from a 57 by 207 meter barrel with a pitch of 2 meters, from which 5 domes with heights of 9 m (1 pc) and 6 m (4 pcs) are morphed. This results in a substantial number of different geometries for the individual components.

A tubular steel frame is set as the primary structure on site. Connected is a square grid of Wooden beams with a grid length of 3m, which serves as the base for three- and four-cornered roof elements. These roof elements will carry a green roof.


The support grid is made up of a total of 1798 beams of different construction and complexity. Due to symmetries and repetitions in the roof geometry, the number of different beam shapes is reduced to 742 pieces.

Each beam is pre-assembled from up to 41 individual individual elements (connecting parts, cladding elements, wooden blocks, etc.) and up to 484 fastening elements (screws, dowels, etc.). The supporting structure consists of a total of 262,756 recorded components and weighs 810 tons.


The core element of each carrier is a glulam beam, which is made out of laminated wooden slats in a press bed. For each carrier, the press bed data and the processing data for the CNC joinery machine (bvx files for Hundegger PBA) were created automatically.


In addition to the production data of each carrier, plans and production data for the individual components were also created automatically: 1,092 steel parts (steel beams, connecting plates, mounting angles, etc.), 2,121 wooden blocks, 2,365 veneer laminated panels.

The beams were clad with 2,121 different wooden blocks and 2,365 cladding panels made of laminated veneer lumber.

The roof area is made up of 2,160 triangular and 231 square roof elements, including connecting elements resulting in a total of 124,559 registered components with a total weight of 533 tonnes. As with the carriers, the number of individual elements is reduced, for the element construction plant (Weinmann) 1,052 different data sets were created. In addition, production data was required for 8,956 individual components (beams and plates, formats bvx, bvn and bv for Hundegger K2 and PBA).
