The swimming and adventure pool in the Luxembourg city of Strassen was opened in the spring of 2009 after two years of planning and construction. Leading up to this event, 570 m³ glue-laminated wooden trusses, 4,500 m² prefabricated ceiling elements and three bridge structures with 18 to 42 m span lengths were designed and assembled. The shell construction was erected as an elliptical paraboloid with a surface area of 120 m x 75 m and a height of 18 m. Due to the changing radii, virtually every building element had to be produced individually. Despite the geometrically diversity of the forms, the greatest challenge was to develop a basic construction methodology with recurring attachment specifications and an intelligent assembly sequence.
The roof was designed with a 4,500 m² membrane roofing with photovoltaic modules and another 5,500 m² covered with aluminium shingles. A smooth workflow was warranted right up through closure of the building shell because the constructive facade work with 2,600 m² of post-and-rail structure, the glazing work and the window work were all carried out by a single source.
