Dome

Detail, showing inverted forms; August 11, 1970, saw the formation of a joint venture consisting of New Orleans architects, Curtis & Davis (the principal designers); Edward B. Silverstein and Associates; Norman, Nolan, and Nolan Architects; and St. Louis' Sverdrup and Parcel Associates Engineers. Even the general contract was a joint venture, because of the tremendous size of the project. This was accomplished between Huber, Hunt, and Nichols, Inc., of Indianapolis, Indiana and Blount Bros. Corp. of Montgomery, Alabama. "The Superdome is the largest fixed domed structure in the world, but it lost its title as the largest domed structure when the Georgia Dome in Atlanta was completed in 1992. (Both the Superdome and Georgia Dome were surpassed in size by London's Millennium Dome in 1999.) Nonetheless, its structural steel frame covers a thirteen-acre expanse. Its 273 ft. tall dome is comprised of a Lamella multi-ringed frame and has a diameter of 680 ft. In 2005, the Superdome came to international attention when it housed thousands of evacuees seeking shelter from Hurricane Katrina."
