A little off topic, but that post sparked my imagination: how are the forms raised anyway? Does the crane pick them up? How do they lock into place so firmly? Are they on some sort of rail system? They don't sway in the wind when they're being lifted. They just go straight up.
I would have thought they were hydraulically jacked, but the crane is always in position over the forms being lifted (as in the pic)... I'm sure we'll get an expert answer soon.
