It seemed to be mostly steel. The would put up steel beams to hold the floor above it, hundreds of them, and then had two special cranes just seemed to pour concrete - They were like fifteen stories tall and instead of a cable with a hook, it was a flexable pipe that seemed to pour concrete or something similar. Then they would lift up these huge prefab pieces. It was amazing really. I never saw something like that.
