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.

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial sequential 1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1264.webp after OCR/catalogue and existing reports. Actual clockwise reading rotation 0 degrees. Normalized access-image regions before rotation. Full fine-region extraction remains outstanding. Partial timed visual review: Text-first audit then sequential WebP and targeted derivative crop; new selected region properties only. Partial timed visual review: Stair H basement/first plan and selected Stair F section B-B callouts, inspected sequentially. W227 Stair F finish/count properties from prior package omitted. Partial timed visual review: First-floor Stair H independent numbered-band recount. Two crops; starting digit 1 not securely readable. Partial timed visual review: Bounded endpoint/profile regions only; no complete-sheet extraction or physical geometry approval. Partial timed visual review: Selected fine closure only; not exhaustive source extraction. Partial timed visual review: Selected native original-layer crops reviewed; untouched regions remain open.

Highlighted reading: DOWN 21 RISERS. Rotated printed first-floor plan flight label; text verified with upright crop. Not a vertical dimensional height.

Unresolved extraction work

Partial locator only: review all fine dimensions, specifications, note regions and companion details
Reconcile original linework with handwritten annotations/revisions
Register physical instances, quantities, element dimensions and spatial relationships
Remaining fractional dimensions and endpoint classes
Host wall, opening, landing and component profiles
Companion sheet registration and revision reconciliation
Independent placement/model checking
Complete fractional dimensions and witness endpoint classification
Installed instance registration and component quantities
Companion details and handwritten revision reconciliation
Independent modeling and checks
Complete fine dimension chains and classified rough/finish endpoints
Source-to-building registration, landing polygons, slab openings and installed instances
Companion detail/revision authority and independent physical checks
Rail-to-rail clear width and rough/finish face classification remain unaccepted
Closed landing/slab-opening boundaries, physical elevations and headroom
Checked source-to-building transform and installed instance applicability
Full unreviewed notes, fine profiles, connections and revision authority
Accepted rail-to-rail clear width and complete rough/finish/rail face classifications
Closed landing/slab-opening boundaries, complete nosing/rail/string profiles, headroom and connections
Checked source-to-building registration, installed instance applicability and independent physical checks
Every unvisited note, material code, schedule, detail and revision remains not-reviewed; no irrecoverable gap asserted
Initial1 remains illegible in both reviewed exposures; do not certify eight-rise first band
Complete fine dimension/profile chains, fasteners, connection details, material and finish extents remain partial.
Installed instances, floor applicability, governing revisions, closed landings/shaft boundaries, headroom, accepted registration and independent physical checks remain unresolved.
Initial 1 remains illegible in two prior exposures; first band is not certified as eight rises.
