This hallway is covered in drywall, the walls are installed before the ceilings are installed. In the ceiling we can see the pipes, plumbing, and the sprinklers. The light bulbs are also installed (meaning the electrician has also been working) In the hallway is also a carpenter's table with a saw to cut materials as needed.
This floor is ready to be drywalled, the insulation is already put in the wall between the studs. The electricians have not installed the lights on this floor.
