Ala. The middle roof, sloping and curving in a skewed line, was more difficult to detail than the main upper roof. Ga. The double top-chord truss was set on shoring towers in nearly three equal lengths. Then the tension ties and compression arches were assembled in the air, through the shoring towers. After completion, the towers were jacked down and removed. Shoring towers were then removed and set up for the proscenium truss opposite, where the procedure was repeated.
Every truss is set to a different camber.
Concurrently, Williams erected the low roofs with separate crews. Gordon says one of the problems with the high roof was that the engineer provided differential deflection criteria after detailing had commenced. It was a tone set by Turner, they concur, in an attempt to provide a better arena. All have their fingers crossed that the paint will be dry by the impending opening on Sept. 2.
