First steel beams have been erected, using some special mobile crane.
Why couldn't they use the previous mobile crane on site, or even the main crane?
I also wonder why they have started doing this at night, safety reasons maybe?
The beams look incredible from street level. I'll grab some pics today and post later. In all the core is almost up to our 10th floor lunch room (10 + Mezz, so 11 stories in all.
