The architects responsible for the project: Sergio Pereira and Roberto Madrid proposed a laminated wood roof in their initial proposal. With time running out and the need for a more agile construction process, they opted for membranes as a better solution and decided to work with Cidelsa for the guidance during the design process.
The roof is made up of 62 modules, radial at the vertices and rectangular at the straight sections; the structural configuration is made up of metal columns attached to the concrete columns, with 18m flat reticulated section trusses. and a central ring that in each module has a V-shaped grid. This grid allows the membrane to be defined in a double curvature with a valley that begins in the lower part of the V-shaped grid and ends in the external perimeter beam at the same upper level of the cantilever beams.
With the slope of the valley towards the perimeter and a gutter over it, the evacuation of water from the roof surface is solved.
Regarding the side enclosures, these have as a structure the same metal columns that support the roof and the beams on the outer edge of the roof. Each module has a tension cable, the same one that transmits the stresses through the cables anchored in the concrete columns, forming at the same time flexible edges with ogival shapes.
