The design intention of the new security gates is to threefold, to:
Maintain the transparency and openness of the original building
Be true to the hall’s deign vocabulary
Provide the needed level of security

The horizontal steel construction of the gates is derived from the steel detailing throughout the existing building, most prominently in the exterior curtain wall system. The linear motif is also common in the building, appearing in the floors and ceilings, as well as the delicate fluting of the concrete towers.
