Customized engineering solutions enabled a complex form while providing an optimal acoustical environment inside the performance halls.

The design called for a glass-enclosed atrium connecting the two main performance halls to one another and the city beyond. To support the need for transparency, Arup's structural engineers designed a cable-supported glass roof, enabling a column-free space. Nonlinear analysis and form-finding were used to balance the effects of gravity, wind, snow and other conditions and determine the most structurally efficient shape for the cabling. Splaying the external rods out from the centre rather than running them straight out from the building provided structural stability, allowing for the elimination of cross-bracing on the curtain wall - a significant aesthetic benefit.
