The double-curved line changes continuously both in value and in pattern, maintaining a very limited gradient, which implies a remarkable design accuracy in defining and controlling the envelope shape. The introduction of two large water collection channels and relating slopes increases the complexity of the geometrical junction.
On the other hand, the pattern of the metal structures defines a different surface from the “objective” area, besides being subject to assembly tolerances that, due to the large size of the structure, prove to be significant at curve variations analysis.
Once developed the “objective” area, Politecnica’s designers focused on the concept and engineering of the system of structural components supporting the roof envelope – with their “continuously changing seriality”, contributing to the achievement of the geometrical, formal and construction shape.
The roof shall in fact assure the essential resistance to wind and seismic action for compliance with locally applicable codes, as well as meet Foster+Partners’ performance standards.
Moreover, digital data processing was specifically required throughout the design activity.
The “objective” area enables to control each and any component, starting from the relating geo-referential position in the assembly. The obtained sequence is complete and, the production process being distributed in different workshops, with a functionality providing up to individual shipment packings definition.
