Highlights
- A special feature of the first tower is its great height despite a small footprint. The concrete tower soars 288 meters (945 feet) above the city featuring a narrow irregular-shaped lantern on the rooftop.
- One of the challenges with the concrete work was the oval-shaped atrium roof design - approximately 200 feet by 125 feet - that covers the seven-story atrium in the retail podium.
- The roof’s cross sections vary along the span, as do the cross sections of its supporting columns, resulting in a visually dynamic but technically challenging atrium.
- The 48-story concrete second tower is approximately 228 meter (749 feet) and is also built on a small footprint. Lateral stability concerns, poor site soil, seismic considerations and a high water table complicated the second tower’s design.
- The conventional concrete frame-shear core wall lateral support system and deep mat with long friction piles were used to produce a functional building economically.
