Actually, isn't a 1 hour rating required, and that is two layers of 5/8 x rock? the two layers can be on one side, and staggered seams. if you have screw inspections where you are, you will have to have each layer inspected, one before the second layer is hung, the second before mud and tape. the door can be 20 min, but the walls min 1 hour.
