Hopefully this will be steel frame construction. It would be nice to see a tall one, or any building for that matter, go up using something other than that boring poured concrete.
Although I've been known to be mistaken recently, since this is an office building it is almost inevitable that it will be a concrete core and steel frame with aluminum, glass and stainless steel curtain wall façade. . . perhaps Steely can correct me if I've misled anyone
