Buttress Work Complete at $930M WA Arena

The $930 million Seattle arena renovation is now in full “building mode” after crews finished the excavation and roof support process last week.

The construction milestone comes weeks after the city announced a naming rights deal with Amazon to name the structure “Climate Pledge Arena” along with a slew of sustainability goals for the arena.

In addition, the National Hockey League officially revealed the team name that will call Climate Pledge Arena home: the Seattle Kraken.

Project Background

The Seattle City Council took the final step in green-lighting the redevelopment of the historic KeyArena in September 2018, unanimously approving the deal with The Seattle Arena Company, or ArenaCo, which included Oak View Group. Oak View at the time tapped the joint venture of Skanska and AECOM Hunt as the general contractor of the project, with Populous as the architect and CAA ICON as project manager.

The $930 million Seattle arena renovation is now in full “building mode” after crews finished the excavation and roof support process last week.

For the project, all updates to the structure will be done without touching the arena’s famous roofline. Since the arena is a designated historic building, four supporting pylons will first be installed so that the entire interior can be redone. The playing floor will reportedly drop 15 feet, to 58 feet below grade, allowing playing lines for hockey and basketball to line up.

An additional 50,000 square feet will be added for more storage and premium club space, which will offer views of the Space Needle. The capacity for the venue will be expanded to 17,400 for NHL games at 18,600 for NBA, meaning the building’s area will grow to 750,000 square feet.

The new arena will be home to Seattle’s WNBA team the Seattle Storm, with fingers crossed for an NHL team and eventually an NBA team as well.

Originally, the project was supposed to be completed in time for the 2020-21 NHL season with a price tag of $600 million, both of which have been pushed incrementally since the project’s inception.

In August 2018 (before final approval), OVG pointed to steel and aluminum tariffs as part of the reason for the rising price. The cost hikes were also partly to blame for the replacement of general contractor JV Skanska and AECOM, which was swapped for Mortenson Construction less than a week after the groundbreaking at the end of 2018.

In May 2019, the budget was updated to the $930 million price tag with an opening date of June 2021.

In January of this year, the roof entered its “floating phase,” when it was suspended by the temporary structure of 72 steel columns. New foundation was also poured at that time.

In May of this year, exterior wall work began as the project was able to remain unaffected by the COVID-19 pandemic. At that time, the arena floor was complete—53 feet below ground, about 15 feet deeper than the original floor—giving the space its new square footage of just over 800,000.

What Now

All concrete y-columns and buttresses are now reconnected as of last week with the completion of the south buttress.

“It’s the piece to tie the roof in so it is completely freestanding,” said Jesse Erickson, quality engineer for Mortenson. “The south buttress has been difficult and challenging ... we had to tie into the buttress with geometry and angles the ironworker crews had never done before, tying in re-bar at the perfect angle.”

ArenaCo

The construction milestone comes weeks after the city announced a naming rights deal with Amazon to name the structure “Climate Pledge Arena” along with a slew of sustainability goals for the arena.

The process also required pre-engineered geo foam cut at precise angles for the space and at times required consultation with engineers “by the hour,” according to Erickson.

That last bit of work finalized what was needed before the full scale-up of the arena.

“We’re building the arena now,” said Ken Johnsen, construction executive for Oak View Group and the Seattle Kraken, referencing the steel erection work well under way in the northeast and northwest corners of the site. “We’re done with excavating, temporarily holding up the roof and putting in the underground [utilities]. We are now fully in building mode.”

That building mode now includes the goal to be the first zero-carbon arena in the world, which was announced at the end of June, along with the Amazon partnership and naming rights.

According to reports, the arena will be powered exclusively by renewable energy including both on-site and offsite solar rather than the use of natural gas. The arena will run solely on electric for daily operations, eliminating all fossil fuels from the building and installing the first all-electric dehumidification systems in the NHL.

The project has several other goals, including:

  • The first arena to ban single-use plastics and commit to functional zero waste;
  • The first arena to fully offset the carbon emissions of all events and related transportation by fans, sports teams and entertainers, achieving carbon-neutral operations and use;
  • The lowest embodied carbon arena in the world; and
  • The greenest ice in the world using rainwater, refrigerants with zero greenhouse gas emissions and electric Zambonis.

The arena aims to earn a Zero Carbon Certification from the International Living Future Institute.
