Pardon our dust; we're working on a new installation that affects the Atrium and Floors 3, 4, and 5.
Installing "Mark di Suvero at Crissy Field" took three and half weeks of work and required 10 riggers, two crane drivers and a forklift, as each steel sculpture weighs between 30,000 and 70,000 lbs. In this time-lapse video, you can see the entire monumental exhibition take form in just over two minutes!
