Delon Hampton & Associates (DHA) provided all structural and civil engineering services on this 1.3 million SF, multi-use urban facility. It is composed of six parts: retail, cinema, residential, parking garage, atrium office floors, and an office tower building. The retail and cinema levels are multi-story steel-braced frames with supplemental moment frames. These floors are composite slabs and composite steel beams. The nine-story residential portion is post-tensioned flat slabs with concrete columns supported on and by the steel braced building. The below-grade parking garage is a regularly reinforced flat slab supported by concrete building columns and concrete walls. The main building is supported on a three-foot, six-inch thick cast-in-place mat. The office tower building is structurally separate from the rest of the multi-use facility and is a steel-framed building with a braced vertical transportation core. This tower is founded on caissons extending to below the lowest adjacent parking level.
