1. Unlike buildings like Aqua even today, the IBM, completed in 1972, incorporated thermal breaks in its steel construction that insulated the building from outside weather conditions and made it much more energy efficient than most of the skyscrapers of its time.
own building across Wabash from the IBM until it was demolished to make way for Trump Tower. The below-grade space was where the Sun-Times stored its supply of massive roles of newsprint.
That is why the plaza along the river edge is basically a flat surface that goes vertically down to the river without any gesture to bring the river into this [IBM] development . . . I've always regretted that in a way because I think it would have been wonderful to open up the plaza and cascade down, similarly to what Trump has done since then.3. The newsprint was delivered via the train tracks that run under the IBM, under Marina City and points west, part of an original railyard dating back to the time when the Wells Street Station was on the current site of the Merchandise Mart. These tracks ran right under the center of the IBM, and so instead of the usual central service core for elevators and staircases, the IBM actually has two cores, split on either side of the old tracks.
Mies was willing to live with it . . . It was a triangular piece that came right into the property that was public right-of-way for Wabash Avenue, and it would have meant to build the building with a reduced width in the center of the building and then towards the north and south make it wider again as a typical office building. And we developed this scheme in the Mies office that expressed that. So it was in a way very un-Miesian, but we of course rebelled and we said why don't we go and talk to the city about IBM acquiring it.
