Check out View 3 and you'll see 2 things are happening at the top. First, there is a steel separator now across the middle of the final poured floor, effectively splitting it into 2. That matches up to the renders and allays my confusion there at the one giant poured floor. Second, there is steel showing up above the final pour, on the far side of this view. Right now it's obvious on the upper right corner, but depending on when you see this link it might be fully obvious. That top-level steel is for the mech and will bring this to approximately 485' (I have also seen 487'), or 24th tallest in the city. The 2 buildings it will be jumping are the taller Ritz Carlton tower at Millennium Place at 475', and 225 Franklin Street, which most of you know as the old State Street Bank tower before 1 Lincoln, at 477'.
