Thanks guys. Mopacs, that one almost happened by chance. The sun was setting of course, but I was also fiddling with the settings a bit while shooting the main building. It actually wasn't quite that dark when I took the shot, just a few shades lighter. But that setting 1/2000 I believe on the shutter dial, brought out the dark colors of the sunset. I guess it could be a sort of sneaky way of faking a sunset.
I can't get over how good the crown is looking. I'd still love to see the "eyebrows" though. I'm loving the curved facade up there. Also it's becoming clear how good of a job they did on creating contrasts with the glass and metal? facade. It looks great.
Strayone, the water tower at Mueller used hydraulic jacks to lift the top of the tank up. I think they said the whole tower weighs 16 million pounds. Anyway, they used these sort of jack stands atop the shaft of the water tower. They then had cables running through those jacks which acted like pulleys to lift the entire top of the tower up the shaft. This method is pretty common in building structures with a narrow shaft topped with a dome, bowl or some other larger structure. If you can believe it, they used the same method for building the Tower of the Americas in San Antonio. They poured the concrete for the shaft of the tower, then built the "top house" - (the observation deck) on the ground around the shaft and then lifted it 550 feet up the shaft using the cables and jacks. There's some photos of the tower under construction with the top house half way up the shaft. Pretty amazing. Anyway, they used the same method here.
This page shows construction of the water tower's shaft. The crane in the photo there was used for construction of the shaft. The jacks they used to lift the top lined the rim of the shaft all the way around.

Fox7 had a reporter there the weekend before they raised it and explained how they would do it. I haven't been able to find any photos or video of them actually doing it though.
I have a few more photos of it to post. I was out at the Expo Center today in East Austin and it really looms on the skyline there. I was kind of surprised how big it looks.
