Checking a heavily loaded wooden rick warehouse for movement or loss of level using fixed reference points such as corner plumb bobs and documented observations.
Rick-warehouse monitoring turns structural movement into an observable condition.
Historical purpose
Use a fixed reference such as a hanging plumb bob to detect whether a heavily loaded wooden warehouse or rick assembly has moved out of vertical alignment.
Inputs
Known reference points, plumb indicators, location records, prior observations, and an escalation path to qualified structural personnel.
Sequence
- Preserve the reference point and indicator position.
- Inspect for displacement, new lean, binding, cracking, moisture, or load changes.
- Compare the observation with prior records.
- Restrict access or escalate when a change exceeds the facility's engineering rule.
- Record inspection, decision, and corrective action.
Evidence and boundary
Peachee visually documents a plumb bob in George T. Stagg Warehouse B at PDF screens 112–113 and captions the broader practice. The source does not establish inspection frequency, tolerances, or structural sufficiency; those require engineering authority.

Any operating sequence above is a researcher-organized model, not a procedure established by this photographic book. Photographs document appearance; captions supply attributed functions. Full-source completion remains open for soft embedded fine print. Image67 is an Ohio state price label, not proof of a federal bonded stamp; caption68 does not establish a universal post-Repeal bottled-in-bond requirement. A plumb line indicates vertical alignment rather than complete structural safety. Material choice or warehouse design intent alone does not demonstrate fire performance or sensory outcomes. Preserve the source-specific limits before Academy reuse.
