This achievement can be missed depending on which room you transport the fellow survivor into. To unlock 002 you need to start Act I, complete the Crane/Egg puzzle at the top of the lift and transport him downstairs. Once he's downstairs, use the tower in the middle of the room to change only the section of track closest to him. So he gets transported into the south-eastly room. The surgical procedure carried out in this room will sadly kill him, leaving his arm on the floor. The 002 achievement will pop when you pick up his arm.
At this point you can reload Act I and get the 001 achievement if you so wish. See my video below for more detail and puzzle solutions.
