The measured building.

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.

Source photographs: 464
Identified objects: 4872
Verified printed values: 12046
Disputed values: 20

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.

ROOF PLAN

Sheet W11

Extraction: Reviewed · extraction partial. Source-space roof envelope, light court, composition-roof regions, three equipment headhouses, fan-room upper volume, visible stair, stack, skylights, selected vents and local spot levels Main roof physical field gate; one IMG_1327 detail inspected after text audit, no accepted solid. Partial timed visual review: Sequential 2200px WebP review; additive selected remaining properties only. No geometry acceptance. Partial timed visual review: Text-only reuse checkpoint; no image reopened. Prior evidence and unresolved work retained. Partial timed visual review: Full derivative locator inspected once; no new fine notes accepted at locator scale. Partial timed visual review: Full architectural region inventory by existing object/property sources, with explicit pending work. Reused bounding regions do not certify exhaustive visual coverage.

Highlighted reading: 15′0″. Local roof dimension witness span only; insufficient to certify whole-roof registration.

Unresolved extraction work

Three separate headhouse cap-roof inset plans
Door-on-roof detail at page upper-right
Complete louvre jamb/head/sill construction
Fresh-air-intake section and material schedule
All small roof spot decimals needing improved reading
Roof framing/control reconciliation
Individual equipment identification
Exact drainage facet boundaries and slopes
All pipe/vent/downspout dimensions
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.
Remaining dimensions and endpoint classification
Materials, schedules and companion details not yet completely reconciled
Accepted source registration and geometry checking
Closed geometry and finish/rough/structural endpoint classification
Complete quantities, schedules, companion details and revision reconciliation
Accepted source registration and held-out geometry checks
Remaining source-local chains, opening marks and quantities
Companion sheets and revision/finish schedule reconciliation
Accepted registration and geometry checks remain separate
All remaining fine dimensions, notes, callouts, schedules and revision authority need regional review.
Accepted finished/rough/structural faces, material extents and closed physical bounds remain unresolved.
Source registration, held-out checks, companion applicability and installed quantities remain unaccepted.
Existing finish/roof controls reused textually; no new visual source call in this bounded pass.
