start at the top, work your way down
This is up 24 floors or so. These men would just jump off, and on back onto the scaffolding. Then they would just lay on the roof and shout down to the others guys, who would shout back up to the guys on the roof. We never really knew WHAT they were doing. But they spent a lot of time going up and down. (Sounds like a bad diet!)
If anyone noticed my new pic on the side, the idea came from *FiTCETERA*
