On the level of the vault with the tranquility loungers there is a room that is locked. Hack the computer next to the door, and enter the room. There is an assault rifle on a table and a holotape is laying on a table that contains overseers password. Take that to overseers office and you can enter. Not much to do in there though.
Vault 112 is in Casey smiths garage once you activate the electrical switch and you will have the doors into the basement open and then you get into Vault 112 and are spoken to by a robo-brain or whatever, and you go into the machine after you change into the Vault 112 vault suit.
The Overseer's office is located on the top floor of the vault. Look for stairs that go up and make sure to check your pip boy. If your not sure just go to local map and the little rectangle with a point is where your objective is.
