Structural Features

  • This 2005 expansion more than doubles the existing museum’s square footage and features 2 gallery buildings, an administrative center, and an outdoor public plaza over a new 5-level subterranean parking deck.
  • The two new galleries are both 5-stories tall and house main art collections, special collections, and new curator spaces.
  • The original 4-level underground parking deck was demolished and replaced with a new 5-level underground deck. New 7 inch post-tensioned slab framing with drop panels at the columns resulted in efficient 9′ floor to floor heights.
  • The new street-level public art plaza above the underground garage is constructed of post-tensioned concrete framing and accommodates large public gatherings, extensive landscaping, and artwork weighing up to 45,000 lb.
