Routine section plan for six rooms and three corridor volumes. Locked section doors are shown only as circulation limits. A walkable survey copy of this floor is available to members: a structural survey taken at a thoroughness the surveyors have declined to repeat, which can be entered and walked. Click the plan, or the button above, to enter. The survey remembers where you stood.

Members are reminded that the survey is a copy. Nothing done there will be held against you, with the usual exceptions. Labels are reproduced as found. Some exhibits are playable. Kindly do not hum.
