A unique two phased project, the first phase consisted of retro-fitting of a 5-level existing parking deck (approx. 500,000 sq. ft.) which included slab on grade removal, excavation, new foundations, and slab pour-back. New shear walls and columns were extended from foundations to top of existing garage.
The second phase of the project consisted of a four-level vertical expansion on-top of the existing parking deck adding approximately 290,000 sq. ft. to the deck. The scope of work included post-tensioned elevated decks, columns, crash walls, and barrier cables. Two 500-series tower cranes were used to support hoisting activities.
