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.

Stair A Basement 1St & 2Nd: Floors

Sheet number unresolved

Extraction: Reviewed · extraction partial. Bounded review of W221: basement, first- and second-floor Stair A plans; Sections A-A, C-C, D-D and E-E; collapsible-gate detail; finish callouts; title and handrail note.

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

thickness
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.
