Scaffolding? Party deck?!? It’s permanent with holes in the back. Can’t get up there easily and it’s in an alley.
Answer: They’re platforms that will eventually hold utilities like electric or hvac equipment for the building. They build the raised platforms to utilize the alley space otherwise it would be cramped.

#3 is a reamer - when a hole is drilled into metal and you want the hole larger, you would ream this bit in and out to enlarge it.
