CSB alert. Took a tour of the stadium a few weeks back with one of the Sr. PMs on the project. Went all over the stadium from field level, to locker rooms, to box seats to the roof itself (the climb up there is a bitch and nor for those scared of heights, as a couple guys in our group quickly found out). From what I recall, the roof will take 8 minutes to open and close once all is said and done. They have already opened/closed multiple times, and are making adjustments to ensure all seals properly align to prevent any leakage (he did not seem to have any fear of leaks once completed). The whole thing is quite the engineering marvel to see up close...<end csb>
And @ texstinger, AC works...
