Today is the day it made another jump. Move the green line up 1 floor (so halfway up that double-floor glassy section) and that's where we should be with this one. One more regular height floor before the ceiling heights increase dramatically.

^^^Thanks! Based on the highest view from the Hub's webcam, I strongly believe that the poured floors are currently up to the green line in the render below. Also, for another way to look at the scale, it's essentially the same height (and similar massing?) to Hartford's tallest building.
