Not long to go!
It appears that there is only one 'taller' or two 'shorter' levels of steel left to go, and it can be seen that the levels of steel making up the final section are not entirely consistent in height. Perhaps someone with an up-to-date understanding of the steel frame may know more?
I'm interested to see what lighting they end up adding to this, really hoping for something iconic to match the building itself.
