Yeah, they are. They span out and reconnect right before the 20th floor, which is the first office floor. Although I didn't expect them to be so small...
The north crane wasn't supposed to jump until december, so says the PA's timetable. I think we can expect the floor-a-week schedule by this january or around that time range. God, I love how fast this tower is moving!
PS: Notice that for the first time in years, the cranes are level again.
