I wonder what crane they used to put that final piece there.

Most likely used a helicopter. I worked at a the bp refinery in Indiana when they had the worlds largest crawler crane, rental was $1m a day and it was only 500' tall. Tower cranes require are braced to the structure they're erecting and that tower probably isn't strong enough.
