Maffeis was designated as the main designer of the roof steel structures of roof and stands, mechanical movement roof system, fabric roof and installation methodology of this outstanding project.

To ensure the movement of the roofing fabric along the sliding direction of the roof, a mechanical traction system driven by a pair of gear-motors with 2 pinions was selected for each roller. An electronic differential control system (master-slave) allows the control system to maintain constant and equal traction. In the case of failure of one of the two motion groups, the pinion can be released and the roller can move at reduced speed.

The design of the retractable roof was made more difficult by the consideration of wind induced dynamic forces. Considering and accounting for these important dynamic forces required for extensive numerical investigation and for wind tunnel testing of scaled samples, with the supervision of Maffeis Engineering.
