 Presentation Description:

The MSG Sphere at the Venetian is located at the site just east of the current Sands Expo and Convention Center, in the city of Las Vegas, Nevada.  With approximately 606,000 square feet of area structured in a 515 feet diameter semi-spherical enclosure, which rises 325 feet in height, this immersive experience performance venue has the capacity to entertain a seated audience of up to 18,500. 

The overall structure of the venue has seven distinct parts; a foundation system composed of drilled shaft piles, socketed into cast-in-place concrete caps interconnected by a grid of grade/tie beams (where necessary), the ground level slab on ground, the stadia bowl and main venue superstructure, four (4) cast-in-place concrete shear wall cores and a proscenium shear wall founded on mat foundations supported on piles, a one-story cast-in-place concrete “collar” structure (coiling around the southern quadrant of the Geosphere), the dome roof arch system (which will hang the immersive LED display plane), a hung grillage system (supported off of the roof and used to support the media plane, catwalk system, and A/V equipment), a two-story “Bridge/Service Building” in Area G, and the Geosphere exoskeleton. 

This presentation will focus primarily on the cast-in-place concrete structural systems of The MSG Sphere at the Venetian, describing the journey that was taken to get from paper to reality.  The presentation will not only focus on describing the various structural components of the project, parametric modeling and algorithmic design, but also the relationships with the various stakeholders and the people involved.
