[i]Once you three make your plan, the elevator/lift door opens to reveal a hall much more utilitarian and barren than the almost eloquent and brightly furnished upper foyer. There's no carpet on the floor, giving everything a very purgatorial and uniform look. You do notice it has a lot of good lighting, and you see two SDO's making their rounds walking over to the elevator, likely curious on who was coming down, or at least being told to confirm your location. 

One waves at you, but it seems they knew someone with the right clearance was coming down because they simply turn the corner and go left down the hall. The forward hall leads...well forward, with four other halls intersecting. Two on the left and two on the right, likely leading into different areas with different cells. 

You see a terminal just outside of the elevator door, which looks to be a list and catalogue of all the criminals and undesirable people they have locked down here. A large touch keypad is laid out on display to be used at your convenience. However, you need a password or you need to hack it to start it up, or it might be easier and less suspicious to simply start walking. You know by the map in your possession that anything that has to do with core units of the ventilation system is through the right hall.[/i]
