MSG Sphere work moves indoors for screen, sound system work


Work has started on the steel frame that will support the indoor LED display under construction in the Venetian’s MSG sphere, project officials said Thursday.

The 730-ton frame will also support the site’s multi-layered audio system.

“The completion of the MSG Sphere domed roof is an important milestone as it allows us to begin the next phase of construction – the construction of the steel structure to support the advanced audio and visual immersive technologies that will make MSG Sphere a one-of-a-kind entertainment destination, ”said Nick Tomasino, vice president of construction for MSG Entertainment.

MSG is in partnership with Las Vegas Sands Corp. to build the $ 1.66 billion, 17,500-seat entertainment venue just east of Venetian Expo. The project is expected to be completed in 2023.

When complete, the 160,000 square foot LED display will be larger than three football fields, enveloping, over and around the audience to create a fully immersive visual environment, with 100 times better resolution than HDTVs from today.

The audio system will include approximately 170,000 speakers and use beamforming technology to deliver crystal-clear sound to every guest, Tomasino said. The system will also be able to simultaneously send single audio content in a directional fashion to specific guest locations in the bowl.

Crews began building the frame inside the site’s bowl after completing the concrete and steel dome roof last month. Designed to support a weight of around 50 million pounds, a significant portion of the display plane will connect to a suspension system located under the dome.

The 3,000 tonnes of rebar were placed, followed by 6,000 cubic meters of concrete, weighing approximately 10,000 tonnes, which were pumped to the roof. The 10 inch thick concrete layer completed the dome, releasing all of its bearing capacity.

MSG officials said 1,300 workers were at the site.
