3/21/19 This building is MASSIVE in person. I stood there for around 20 minutes and countless pedestrians stopped to take pictures.
Hello PittsburghPA
Thank you for sharing your photos. As a side note to your alias will share that I feel Pittsburgh has one of the nicest city skylines of any city in the USA (lush trees, rolling hills, twin rivers, iron link bridges, architectural depth) that has less than 350k people living within the actually city boundary, though one of the worst and for many reasons, Chinese restaurant (not far from Brashear) I have been to in the USA, to include very non Chinese centric cities such as Hartford and Wichita.
As for 110 N. Wacker and reason for commenting, there is little about the load bearing approach taken with the first 3 floors that face the river, and suspiciously looking like an exercise in cost reduction engineering, that I like about this structure, from the multi piece header I beam joining the 6 inverted buttress, to the manner (design) in how the 3 point loads and detached from the slab, mechanically converge just above the ground floor along with how the 3 loads vector into the ground atop just 4 beams of which only 2 beams are under full compression, the center load bifurcating. Simply curious, but it would be interesting to see a FEA for this building and when under wind load with a 1/2" of ice covering the north and west facing sides.
