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.

Unresolved extraction work
  • Exhaustive transcription of every dimension, wall build-up and detail callout
  • Accepted local-to-building registration of W221
  • Exact clear stair width and rough/finish face classification
  • Landing construction, stringers, nosings, soffits and slab openings
  • Handrail profile, bracket detail from W228 and exact start/termination geometry
  • Elevator shaft, hatch and enclosure-wall construction
  • Door, folding-gate, hose-cabinet and tile-wainscot dimensions
  • Independent source-overlay residual checks
  • exact start/end XZ
  • clear/structural width
  • first and last tread edge classification
  • nosing/profile
  • riser-by-flight allocation
  • landing interface
  • structural thickness
  • underside/soffit
  • headroom
  • intermediate landing boundary/elevation
  • closed physical polygon
  • finish and structural faces

  • checked landing elevation
  • flight connection edges
  • enclosure-wall interface
  • closed slab-cut polygon
  • classified slab edge versus wall or tread
  • edge elevations
  • slab thickness
  • beam/landing-bearing interfaces
  • checked W221/W3 registration
  • Remaining small dimension fractions, profile boundaries, fasteners and dense notes require targeted master/clearer companion review
  • Installed instances, quantities, room registration and revisions remain unresolved
  • All-region measured extraction and architectural acceptance remain incomplete
  • Full dimension/profile chains and remaining notes
  • Installed registration, quantities and revision/companion authority
  • 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.
