ARCHITEC TURE , DESIGN & ENGINEERING
at ground level as the proportions of the structure reduced to something more in keeping with the human scale. “Other shared objectives were set. We wanted to sim- plify the detailing of all complex node intersections across the entire roof and to develop a standardised fam- ily of node details that could be replicated wherever pos- sible. This required an update to the geometry to the roof to achieve a more symmetrical design than the com- petition winning roof geometry. An additional parallel truss was added, the main gutter trusses were realigned, the geometry of the roof opening was adjusted and the diagonal trusses simplified.” The parametric model was used to control a multi- tude of other relationships between elements, which would be impossible to achieve using conventional soft-
ware. Each parameter was treated in the same way — structural and architectural requirements were considered, an optimised parameter agreed on and inserted into the geometric control model for the roof. And so, over a matter of months, a fully editable 3D model of the stadium roof was completed, which defined every constraint imposed on the roof and could be used independently by every member of the team.
Cladding Treatment of the Roof The architectural treatment of the stadium roof cladding has been developed to clearly express the design and geometry of the structure and at the same time meet the environmental performance requirements to ensure spec- tator comfort within the stadium.
