Police officials worked with McClaren, Wilson, and Lawrie Architects of Phoenix to help design the building to resist a terrorist attack, isolate potential hazards and control visitor traffic and access. The Boon Edam solution included adding a screening area at the front of the lobby. Once a visitor is cleared, they walk through a Tourlock security revolving door to enter the main lobby. There is an added layer of security between screening area and main lobby; bullet-resistant glass protect against a gun attack; prevention of unauthorized entry; and seamless integration of physical security entrances with modern building design.
