After doing that go to the shack on the left and open up the little manhole. After the game loads you should be in the base run down the hallway and go left after the first turn after leaving the hallway. After making the turn you should come across a room with lockers search the lockers until you come across power armor. Grab it and put it on the run further down the hallway to the elevator and go to the top. After getting to the top go to the hanger on the left and talk to the man named Raul. He should direct you to Quincy. Go to the hanger to the right of the elevator and you should see a man next to a locker this is Quincy.
