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_1123.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: OCR, queue and existing extraction packages searched first. One sequential upright WebP inspection; only additive selected properties recorded. Previously verified readings reused without duplication. No complete extraction or accepted geometry. Partial timed visual review: OCR and existing text packages searched before one sequential upright WebP inspection. Additive region review; existing verified properties reused, not copied. No accepted geometry or cross-floor connection. Partial timed visual review: Existing verified handrail diameter, material rules, maximum bracket spacing, scale and fixing-symbol count reused without duplication. This photograph has no legible printed fastener-size callout in the inspected bracket region. Partial timed visual review: Existing F/G seventh-floor and H first-floor profile scope and handrail material schedule confirmed; upper profile dimensions remain clipped. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. Partial timed visual review: undefined Partial timed visual review: undefined Partial timed visual review: Text reuse only; no new visual claim. Partial timed visual review: Text-only canonical/queue/OCR reuse; no new image inspection. Partial timed visual review: undefined Partial timed visual review: undefined Partial timed visual review: Source-local detail/region evidence only. Printed type/floor applicability does not establish installed occurrences.

Highlighted reading: WOOD OR METAL. Selected visible source evidence; partial locator review, applies only to depicted assembly.

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
Upper profile is clipped by the source photograph edge. Existing caption and bracket/handrail schedule reused; no broad upper-profile closure.
Complete fine dimensions, profiles, materials, finishes, gauges and fastener schedules remain partial.
Installed quantities, room/storey allocation, governing revision and companion applicability remain unresolved.
Source-to-building transforms, rough/finish endpoint classes, complete openings and independent physical checks remain outstanding; authoring is withheld.
Profile top remains cropped in this photograph; complete profile and anchorage require applicable companion evidence.
Complete fine profiles, member sizes, fasteners, finish extents and endpoint classes remain partial.
Installed quantities, stair/storey/room assignment, closed openings, headroom, source-to-building registration and independent physical checks remain unresolved.
Governing original/revision and companion applicability remain unresolved; source reading does not approve geometry.
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
Complete cap/moulding/handrail/string/nosing profiles, materials, gauges, fastener sizes and exact endpoint classes remain partial.
Printed type/floor applicability does not establish installed quantities, storey assignment, source-to-building transforms or accepted physical geometry.
Full region, companion exposure, revision authority and independent installation/profile/height registration remain outstanding; no irrecoverable gap is asserted.
Remaining cap/moulding/handrail/string/nosing fractions, gauges, fastener material/size/anchorage, finish extents and source endpoint classes.
Installed storey/room quantities, closed openings and landing boundaries, rail clear width, headroom, source-to-building transforms and independent physical checks.
Companion/revision authority remains open; no source or floor completeness or irrecoverable gap asserted.
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.
Upper F/G-at7/H-at1 profile is truncated at photograph top; full profile material/gauge/width witnesses await W228 companion.
Bracket screw/anchor sizes and substrate are absent from the visible schematic, not established as unavailable elsewhere.
Complete member/profile dimensions, material/gauge/fastener schedules and exact endpoint classes
Installed stair/storey/room allocation, quantities, original/revision authority and companion applicability
Source-to-building registration, complete landing/shaft openings, independent physical checks and architectural acceptance
