Old Stadium Debris to Get New Start

The Minnesota Vikings’ old home is nearly gone, but more than 80,000 tons of its concrete, steel and other materials will play on in new venues after being salvaged for recycling, state officials have announced.

More than 80 percent of the Hubert H. Humphrey Metrodome—infamously anointed the worst stadium in the United States in 2012—will be recycled by the time demolition is complete next month, the Minnesota Sports Facilities Authority announced March 19.

Demolition of the Metrodome began in February, with controlled explosions bringing down the roof cables after the 10-acre roof was deflated for the last time in January.

The stadium opened in 1982 and hosted two Twins World Series victories before the baseball team left in 2009 for Target Field.

The old stadium will give way in July 2016 to a new $1 billion Minnesota Multi-Purpose Stadium for the Vikings. The new venue is being designed by HKS Sports & Entertainment; the project will be managed by Mortenson Construction and project associate Thor Construction.

The Metrodome roof collapsed in 2012.

Projects on Track

Both the demolition and construction are "moving forward according to plan," said Michele Kelm-Helgen, chair of the MFSA.

"Demolition of the Metrodome will be substantially complete by the end of April, and excavation and foundation work for the new stadium continues. We're also pleased that our demolition plan calls for more than 80 percent of the material that is being hauled away to be recycled for renewed use elsewhere."

In the Recycling Bin

The list of recycled materials includes:

HKS Sports & Entertainment

The new $1 billion home of the Minnesota Vikings will have 1.7 million square feet and more than 65,000 seats.

  • 240,000 pounds of cast iron and 150,000 points of HDPE plastic from Metrodome seats that were recycled and sold to Minnesota manufacturing companies;
  • 80,000 tons of concrete, which will be used in other building projects;
  • 2,500 tons of structural steel, which are being prepped for recycling off site;
  • 2,000 tons of steel, which remain in the structure and will be recycled;
  • 25 tons of precious metals; and
  • 300 tons of roof cables.

Going Up

On the construction end, the stadium authority provided this update of the new 65,000-seat, 1.7 million square-foot facility:

  • Excavation is nearly half complete, with more than 400,000 of an estimated 850,000 cubic yards of material removed;
  • 40 of 300 of the new stadium's piers have been installed
  • 2,500+ yards of an estimated total 100,000 cubic yards have been poured;
  • Underground mechanical and electrical utility work continues; and
  • Foundational concrete elements are being formed.

The Metrodome's roof collapsed four times over its 30 years due to severe weather. Surveillance cameras recorded the collapse of December 2010, when the roof caved under the weight of snow.

A third tower crane on the southeast corner of the site will be installed mid-April. Five tower cranes will be used in all.

The new stadium has an $82 million steel budget, including $5 million for grade 65 steel from ArcelorMittal, a Luxembourg-based company that owns and operates mines on the Iron Range in Minnesota.

Grade 65 steel is being used for the 970-foot-long main truss that will be used for an extremely long span of the roof. The long-span steel required is manufactured only in Europe, the authority said.

The venue will include a translucent roof, five pivoting glass doors that open to a plaza, and a skyway connection to parking, according to a Fact Sheet.

More than 1,100 workers are expected be on site at the peak of the project.

Why do you need 25 tons of precious metals incorporated into a stadium? Hmmm. Roughly 30,000 Troy ounces per ton, silver is at about $20 per ounce... Roughly $15,000,000. Not much compared to the cost of a modern stadium, I suppose. I suspect it is more likely to be copper and brass from the plumbing, not truly precious metals.

If the concrete to be recycled is contaminated with chlorides or carbonation, will it still be good to use that concrete in new construction?
