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.

Tor Stair

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_1265.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 OCR/queue/prior-package audit only; existing verified properties reused without duplication. Orientation not rechecked where null. Partial timed visual review: Typical section at window for Stairs A and C; existing B/D/E and handrail schedule evidence reused. Partial timed visual review: Upper-left typical A/C construction crop. Other common B/D/E and railing facts preserved in existing IMG1122/1123 packages. Partial timed visual review: B/D/E flight rail and landing-newel witness endpoint classes. Two crops; full physical height above tread remains unresolved. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. Partial timed visual review: Bounded endpoint/profile regions only; no complete-sheet extraction or physical geometry approval. Partial timed visual review: Text reuse only; no fresh pixel evidence or exhaustive-review claim.

Highlighted reading: FOR STAIR 'C' 1ST TO 2ND FLOOR. Applicability of same upper-left typical section to Stair C.

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
All unreviewed fabrication details and material-code cells
Newel tube/cap profiles and connections
W225/W226 storey-specific registration
Independent overlay and fabrication 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
Accepted rail-to-rail clear width, closed landing/slab-opening boundaries and headroom
Complete material/gauge/fastener schedules, cap/moulding profiles and finish extents; remaining notes and revisions not fully reviewed
Checked source-to-building transforms, storey/installed instance applicability and independent physical checks
Complete rail/string/cap offsets, tread product and panelled-riser materials not certified
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
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.
String cap/base offset fractions not reopened: prior native crop failed; clearer independent evidence is still required.
