The first layer of drywall is starting to go up.  I took these tonight (Sunday night) so the lighting is a little tough with the camera flash being the only light source.   The mud / tape / acoustic sealant is not yet up for the first layer.  There will be up to 4 layers of drywall on each wall, depending on the wall.   Since the control room is a “room within a room” that means there could be 6-8 layers of drywall in there.   You can also see some of the HVAC returns and vents more easily now.
