When exploring deep in the hallways pas the great billboard you fill find rewire-console on room called A-27 just past the room A-28. There is also a lockers in both rooms when you can hide if things gets nasty. There are also other side of the wall a ventilation exits where you can hide also. And the real price is the blueprints for the pipebomb on A-28. Good luck.
If you continue exploring you will find flashlight batteries in room A-26. I found out that rewiring system is very helpful along the way. Room is also equipped with closet for hiding.
