About half the roof will have a hard covering or deck, with the remainder made up of ETFE, a transparent glass-like polymer that was used to cover the outside of the Beijing National Aquatics Center, also known as the “Water Cube,” site of the 2008 Olympic swimming competition.
“We think clear is the new retractable,” Trubey said.
Kelm-Helgen said the retractable roof was in play “for a long time” and that the final decision wasn’t made until last week. She said it ultimately was dropped because it was too costly and couldn’t fit within the construction budget without sacrificing other features the team and authority wanted.
In general, retractable roofs cost anywhere from $25 million to $50 million more to build and install than a fixed roof, industry experts have said.
“It was very obvious from a budget standpoint that we couldn’t do it,” Kelm-Helgen said.
‘One step closer to reality’
Inside, three of the stadium’s seven levels will feature suites, including some at field level. Elevators, escalators and ramps will take fans to seating in each stadium deck.
Concourses will be wider than those at the Metrodome, and there’ll be “many more bathrooms,” Kelm-Helgen said.
Speaking before the unveiling, Gov. Mark Dayton emphasized the thousands of jobs that the project would create.
“I’m just so excited about tonight because it makes this stadium one step closer to reality,” he said.
More detailed drawings of the interior design and finishings will be unveiled later this summer and fall, in time for the October groundbreaking. The city of Minneapolis has up to four months to review and approve the design and issue the necessary building permits.
“Awesome,” said David Gunderson of Brooklyn Park, as the program wrapped up. “It looks like a ship. The ship has landed.”
Added Ben Theis, of Golden Valley, “I like the idea of the new kind of retractable roof, with the covering.”
Still, one of his big questions remained unanswered after the nearly hourlong presentation.
“Now,” he said, “I want to know about the tailgating.”
