Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.
464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.

Center vertical witness appears to read 3 inches; numeral and exact endpoints require independent review. Not a verified slab thickness and not a complete roofing build-up.

Drawing notation: TYPICAL ROOF SLAB
No accepted field-specific callout or world registration; no placement or underside elevation follows from candidate section readings.
Drawing notation: TYPICAL ROOF SLAB
Close W11 roof registration with well-spread independent dimension or structural controls and held-out checks. Classify and close one physical slab perimeter plus court boundary and all skylight, headhouse, fan-room, drain and access cuts or curbs that intersect it. Transcribe and correlate a roof-field-specific section for structural slab, topping, roofing and underside elevations, with distinct local surface slope/elevation facets. Correlate roof edge to an exterior wall/parapet section with both classified faces, thickness, projection and top/bottom elevations.
