Extraction: Reviewed · extraction partial. Bounded first-floor elevator audit: DETAILS OF ELEVATOR NO. 3. Bounded one-source review of W231 / IMG_1268 for the missing first-floor Elevator No. 3 vertical clear-hatch or shaft dimension and its exact endpoints. Elevator detail-to-W3 physical-placement gate: DETAILS OF ELEVATOR NO. 3. Partial timed visual review: Text-first OCR/queue/prior-package audit only; existing verified properties reused without duplication. Orientation not rechecked where null.

Unresolved extraction work
- Accepted world wall faces and exact shaft polygons for all three elevators
- Registered relationship between W229/W230/W231 detail coordinates and W3 world coordinates
- Rough-versus-finished enclosure wall planes and wall thicknesses
- W217 title-block confirmation and exact endpoint interpretation for the 3'-6" and 6'-9 3/4" door readings
- Exact first-floor Elevator 3 door width, height, jamb/head/sill and rough opening
- Readable Elevator 3 vertical hatch/shaft witness
- Car/cab/platform sizes, rail/counterweight coordinates, pit depths and overhead clearances
- Accepted ramp length, slope and threshold build-up at Elevator 3
- Architecturally accepted reconciliation of all floor traces, especially the fourth-floor mechanical underlay
- A flatter or higher-resolution W231 scan that preserves the full vertical dimension chain
- A typed elevator schedule or dimensioned detail explicitly identifying the Elevator No. 3 clear hatch
- Endpoint classification against the original line hierarchy, followed separately by W231-to-world registration
- For W229, the west outside enclosure face is fixed at world X = -65.020833 ft and the south/north clear-hatch edges are fixed at world Z = 46/56 ft; both clear-hatch world-X edges remain unresolved. For W230, the east outside enclosure face is fixed at X = 65.020833 ft and the clear-hatch east/west edges at X = 66.083333/73.083333 ft; both clear-hatch world-Z edges remain unresolved. Both elevators still lack finite enclosure-face endpoints, opposite faces, wall thickness and complete hatch-to-wall construction.
- For W231, an exact non-collinear column/grid frame and a complete, classified shaft or clear-hatch width/depth chain.
- Rough-face versus finish-face classification and wall thickness for each enclosure side.
- Independently accepted matching W3 hatch or shaft faces and a reported hold-out corner residual.
- Pit depth, overhead, slab opening and cross-floor continuation evidence for each elevator independently.
- World wall plane and jamb-center/inside-jamb offsets for all three entrances.
- Operating clear width and height, rough opening, leaf overlap/travel, sill, head and wall-thickness build-up.
- Elevator 3 first-floor entrance dimensions and endpoint classes.
- An independent check tying each local door centerline to the corresponding W3 landing wall.
- Cab-to-hatch origin, platform size and inside-clear dimensions.
- Guide-rail, counterweight and bracket centerlines tied to classified hatch faces.
- Confirmed assignment of W219 Cab E elevations to Elevator 1, 2 or 3.
- Door operator, travel/pocket and emergency-exit geometry.
- Dimensioned horizontal extents and wall-face endpoints for the Elevator 1 vestibule and Elevator 2 Broadway foyer thresholds.
- Elevator 3 ramp length, slope, threshold build-up and exact landing boundary at EL. 93.25 and EL. 95.33.
- Registered sill/head coordinates and independent correspondence to W3 landing traces.
- As-built confirmation before accepting vertical shaft or landing continuity.
- Remaining fractional dimensions and endpoint classes
- Host wall, opening, landing and component profiles
- Companion sheet registration and revision reconciliation
- Independent placement/model checking
