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.

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.

Detail of Stair D and Fan Room

Sheet W224

Extraction: Reviewed · extraction partial. Bounded duplicate-source review of W224's ordinary third-through-sixth-floor Stair D plan and its two placement witness chains. 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: Whole access locator inspected to confirm reading orientation; diagnostic placement and fan-room acoustic evidence reused, no duplicate properties added. Partial timed visual review: Text reuse only: prior verified evidence retained without duplication; no new visual review or completeness claim. Partial timed visual review: Text reuse only: preserve existing verified stair counts/width controls and unresolved endpoint classes without new visual review or duplicate numeric readings. Partial timed visual review: Text reuse only; no fresh pixel evidence or exhaustive-review claim.

Highlighted reading: DRAWING W224 / DETAIL OF STAIR D AND FAN ROOM. Alternate W224 photograph. Printed controls and the sixth-floor landing exception are corroborated; every candidate building transform remains conditional on explicit column and wall-face offsets.

Unresolved extraction work
  • Independent proof that Columns 82 and 68 lie exactly on the candidate framing-line coordinates rather than at nonzero connection offsets
  • Rough-wall versus finish-wall classification for the 1-foot-4-inch witness endpoint
  • Exact wall line referenced by the 9-foot ordinate
  • Reconciliation of the non-closing provisional fourth-floor trace and the residual fifth-floor trace
  • Rough-versus-finish classification and independent plan reconciliation of the 4-foot-4-inch sixth-floor wall-witness variant
  • Accepted host wall, entry jamb, threshold and slab-opening geometry
  • Printed individual riser heights, construction thicknesses, stringers, rails, nosings, headroom and landing support
  • Remaining fractional dimensions and endpoint classes
  • Host wall, opening, landing and component profiles
  • Companion sheet registration and revision reconciliation
  • Independent placement/model checking
  • Non-closing plan traces and column/wall endpoint reconciliation
  • Host opening and threshold geometry
  • Full fabrication extraction
  • Independent model checking
  • 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
  • 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.
  • No pending source-reading IDs does not mean exhaustive review; unrecorded notes, profiles and structural interfaces still require coverage.
