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.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial locator review: catalogue/OCR searched before sequential inspection of one <=1000px JPEG65 derivative from public/archive/drawings/complete-upright/IMG_1130.webp. Selected visible regions only, not full measured extraction. Coordinates normalized to unrotated access image; principal lettering upright. No modeling authorized. Partial timed visual review: Source-local printed evidence only; endpoint finish classes, installed locations and accepted geometry remain unresolved. Partial timed visual review: Machine-room trap local setting-out witnesses; previous trap dimensions, room bounds, door size, materials and floor elevation retained without duplication. Partial timed visual review: Source-local detail only; no installed quantity, floor geometry or accepted model placement. Printed floor/room assignment preserved separately. Partial timed visual review: Prior text/register/inventory crosswalk only. All numeric/notation/review history remains in canonical source records; no newly verified property or floor/shaft geometry. Partial timed visual review: undefined Partial timed visual review: Source-local detail/region evidence only. Printed type/floor applicability does not establish installed occurrences.

Unresolved extraction work

locator review only: remaining dimensions, fractions, notes and companion details need targeted extraction
material/finish specifications, installed quantities, revision authority and placement registration
complete image-region coverage and source-to-instance reconciliation
Remaining fine dimension chains and fractions
Companion detail and revision reconciliation
Installed instance and world-coordinate registration
Remaining plan fractions
Colored revision applicability
Grid/floor registration
Full regional coverage
Remaining witness dimensions, fractions, hardware and material notes need targeted master/companion review
Floor/room instance registration, revisions, installed quantities and connection topology unresolved
All-region extraction and architectural acceptance remain incomplete
Remaining fine fractions, complete member profiles, fastener sizes/materials and finish extents require targeted source review.
Installed room/floor identity, exact rough/finish/cab/rail endpoints and companion registration remain unresolved.
Source-to-building transform, installed quantities, independent physical connections and architectural acceptance remain withheld.
Different vertical witness stations remain separate;14′1″ central chain is not a replacement for right-hand14′0″/outer15′1″ witnesses.
Orange/brown marks visible on paper are not accepted historical revision instructions.
Small upper trap floor/installed identity and hinge/anchor construction unresolved.
Text-reuse-only disposition: no source pixels opened or new visual coverage claimed in this follow-up
All exact values, historical nulls, conflicting station/revision layers and review states remain in their original registered properties
Remaining material specifications, hardware, geometry and installation questions require targeted evidence
Complete fine dimensions, profile/fastener/finish schedules and remaining notes require targeted review.
Installed identities, quantities, governing revisions, companion applicability and source-to-building registration remain unresolved.
Source findings are preview-only; no physical geometry or architectural acceptance.
