The underground parking structure is a four-story cast-in-place garage with two-way PT slabs and beams. The foundations are pile caps and strip footings on nearly 800 auger cast pile 24” dia. The structure extends 60 feet below grade and has approximately 1.2 million square feet and 2,500 stalls. The garage structure is also unique in its design as it doesn’t have any expansion joints or interior shear walls. Its bracing is achieved at the perimeter walls only and strategic sequencing, mix designs, curing methods, leave-out areas on pourbacks, etc. were all required to minimize slab cracking.
