The MSG Sphere at The Venetian (US) will soon start looking more sphere-shaped as 32 massive roof trusses will be installed. The installation of the 32 trusses will be a highly coordinated effort.

The ‘Las Vegas Review Journal’ stated that the first of the 200-foot trusses, weighing more than 100 tons apiece, has been put in place by construction crews.

The MSG Sphere at The Venetian is a sphere-shaped music and entertainment arena being built in Paradise, Nevada, near the Las Vegas Strip and East of the Venetian resort in the United States. The 17,500-seat auditorium was initially scheduled to open in 2021, but construction was suspended in late March 2020 due to a disruption in the project’s supply chain as COVID-19 took on monstrous form in the US. Construction resumed later that year, with the opening rescheduled for 2023.

‘The Sphere’ – an architectural marvel – is a $1.66 billion, 17,000-seat, futuristic entertainment venue scheduled to open in 2023. Madison Square Garden Entertainment Corp. (world leader in live experiences) is building ‘The Sphere’ East of The Venetian, Palazzo and the Sands Expo and Convention Center.

The ‘Las Vegas Review Journal’ further stated that it’s a gigantic three-dimensional puzzle that, when the roof framing is completed this summer, will house screens that will span the size of five football fields. About 600 construction workers are presently working on the site.

Noted Nick Tomasino, Vice-President, Construction, MSG Entertainment, “MSG Sphere’s domed roof will create a column-free interior bowl, which will house the 160,000-square-foot display plane – a key component in the venue’s immersive experiences. This defining feature is the result of expert design, engineering and construction planning, and we look forward to seeing the roof continue to take shape over the coming months.”

Before work could begin on the steel roof frame, crews last month completed the heaviest single lift of the entire development – setting the dome’s 170-ton central compression ring on top of a 285-foot, 677-ton steel shoring tower.

It was a significant step because the 32 trusses will connect the tension ring – it has a circumference of 1,380 feet, a diameter of 440 feet and was built with 2,730 tons of steel – to the 170-ton compression ring that sits atop the temporary 285-foot shoring tower.

After each roof truss puzzle piece is set up – 16 will be laid in place around the entire ring with the other 16 filling in the gaps – the finished roof truss system will be able to support 21,000 tons.

Once every roof truss is in place, the shoring tower will be dismantled, but the equal force created by the compression ring and the steel tension ring will act as a buttress for the domed roof frame to stay in place.

As each of the trusses is too huge to be transported, so they are being bolted and welded together at the Sands Avenue construction site.

Once enclosed, inside the venue, the largest and highest-resolution LED screen on Earth will wrap over, up and behind the stage and audience in an immersive environment at a resolution 100 times better than today’s pick of the lot high-definition televisions.

A state-of-the-art acoustics system will deliver audio to every seat, from the front row to the back. Beamforming technology will enable simultaneous delivery of multiple forms of audio content.

Beamforming technology focuses a wireless signal towards a specific device, rather than having the signal spread in all directions from a broadcast antenna, as it normally would. The result is a more direct connection that is faster and more reliable than it would be without beamforming.

An infrasound haptic system will use deep vibrations to enable guests to feel the sound. A new connectivity system will deliver 25 megabits of data per second for every guest with 1,100 Wi-Fi access points.

Once completed, the MSG Sphere will shine on the Nevada skyline – it will be 366 feet tall and the building will be 516 feet wide at its widest point. By comparison, the nearby Palazzo tower is 642 feet high, The Venetian is 475 feet tall and the High Roller observation wheel is 550 feet.

MSG Entertainment, which operates Madison Square Garden and Radio City Music Hall in New York, is collaborating with Las Vegas Sands Corporation on the entire development.

The Las Vegas Sands Corporation is an American casino and resort company based in Paradise, Nevada, United States. Its resorts feature accommodations, gambling and entertainment, convention and exhibition facilities, restaurants and clubs, as well as an art and science museum in Singapore.
