When waiting for the Funicular to come up in Picus Communications, enemies will appear. Before pressing the elevator button, save the game. Use heavy objects to block both entrances into the room. Note: This requires the Move/Lift Heavy Objects Augment. You can use the two vending machines outside the room, two crates next to the security computer, and the turret in the middle to block the lower doorway and the side corridor. If done correctly, the guards will stay outside while you are waiting for the Funicular.
