2023 OPA Winner: Climate Pledge Arena
The transformation of Seattle's historic KeyArena into the
state-of-the-art Climate Pledge Arena, home to the NHL's
Seattle Kraken, was no small feat. The $930-million
renovation and expansion required the near-total demolition
of the old structure and construction of an 800,000 sqf (74,000
m2), below grade venue while keeping its landmarked fa├žade
and roof intact. To do that, the project team had to come up
with solutions for excavating 680,000 cu yd (520,000 m3) of
soil to make way for the new 17,000-seat arena while working
around the massive temporary shoring supporting the
44 million lb (20 million kg) roof - all in time for the NHL's
2021-22 season.
