I believe the level they are working on now is what is referred to as "Roof Level" in the image below. That would leave about 50' to go to reach the top of the crown.
This is sort of becoming an underrated tower. It's very prominent already in the skyline and the crown isn't even being worked on yet. Obviously, I hated it for how we got bamboozled from the originally planned tower but this isn't a bad looking tower.
