I just spoke with John Lahey, who is Presigent of Solomon Cordwell Buenz. I was expecting to leave a voice mail, but hey, what can I say. At this time a rendering is not avaliable
I was told that they are still in the early design phase, and it would be 1-2 months before something might be presentable.
He was unable to confirm if the height of the building was being measured from the bottom of the pit or from the upper levels of Lake and Stetson, which is where we want the measurements taken from.
He mentioned that the programming for the Mandarin Oriental was a bit different than what they expected, so some things are being worked on.
What I'll probably do is check back in with him at the end of August, and maybe something more will be available. Until then we need to be parient, (which I know is hard for some of you) and keep this thread active with questions and speculation.
