2016 North American BIM Awards - Hollywood Casino Jamal

Hollywood Casino Jamul is a three-story entertainment facility with approximately 200,000 sq. ft. of gaming, restaurants and lounges atop a below-grade, eight story, 1800-space parking garage. The casino structure’s innovative steel lateral system utilizes rocking frames and Krawinkler fuses integrated into vierendeel trusses to produce a performance-based seismic design. The integrity of the perimeter cantilevered gravity system is protected while the lateral system is repairable after a major seismic event.

The parking garage is a post-tensioned concrete slab system with an unconventional construction sequence. In order to compress the construction duration and accelerate the completion of the interior design-intensive casino, the casino steel structure was prioritized ahead of the garage structure below. The steel casino structure was erected first- on early concrete cores and 90ft steel “stilts” that would become encased in the final concrete garage columns. With coordination and input from the contractor, all temporary conditions from start of construction to final completion were included in the structural design. This allowed the casino to be enclosed and finished while, in parallel, the garage slabs below were constructed from the bottom up.
