I am not saying ground level columns will not be clad. I agree that it appears they have plans for these ones. I was just told that the columns on level 70/roof are complete, "as-is".
EDIT— The biggest loss for this building is that the rooftops are restricted space. No unauthorized entry permitted! This is a damn shame. The roofs are actually paved with white pavers and have shoulder high railings on all sides. No danger here. Plus the aesthetic created from being under the "cheese hats" is simply amazing! This space should have been a patio/bbq/sun-deck. Damn shame I tell yah that only a limited few will ever be able to enjoy this...
