Outside enclosure-face span on Column 73-74 row

8.395833 ft

Span between outside enclosure faces along the printed witness row; not a clear shaft or rough opening.

Calculated from: w229-f7-column73-to-column74-span, w229-f7-column73-to-west-outside-enclosure-face, w229-f7-east-outside-enclosure-face-to-column74

Outside enclosure-face midpoint · world X

-69.21875 ft

Midpoint of the outside-face span only; no assumption that the W235 clear rectangle is concentric.

Calculated from: w229-f7-west-outside-enclosure-face-world-x, w229-f7-east-outside-enclosure-face-world-x

W229 outside-face span minus W235 printed clear width

1 ft

Diagnostic difference only. It must not be divided into two 6-inch walls unless corresponding faces and centering are independently established.

Calculated from: w229-f7-outside-enclosure-face-span, w235-img1156-elevator-1-clear-width

Provisional W235 clear-envelope center minus W229 outside-face midpoint

-0.41225 ft

Comparison of unlike face classes. The residual does not authorize shifting the W235 clear rectangle.

Calculated from: w235-img1156-elevator-1-diagnostic-center-x, w229-f7-outside-enclosure-center-world-x

Accepted W235 clear-face world X coordinates

Unresolved: outside enclosure faces are now dimensioned, but the exact relation to W235's clear-plan faces is not yet independently established.

Accepted seventh-floor Elevator No. 1 physical shaft transform

Withheld pending north-south face placement, wall construction, slab opening and corresponding-face checks.

exact_physical_front_to_back_depth

Numeric value unresolved

No classified section or plan chain bounds a physical front component's front and back faces. The W217 6-inch jamb widths and adjacent 2-inch witness are not depth measurements. Physical front and wall cut remain withheld.

exact_physical_front_to_back_depth

Numeric value unresolved

No classified section or plan chain bounds a physical front component's front and back faces. The W217 6-inch jamb widths and adjacent 2-inch witness are not depth measurements. Physical front and wall cut remain withheld.

zero_thickness_analytical_entrance_center_XYZ.x

-69.2795 ft

2 ft W3 trace uncertainty; not a physical host face or exact construction station. Physical front and wall cut remain withheld.

zero_thickness_analytical_entrance_center_XYZ.y

0 ft

2 ft W3 trace uncertainty; not a physical host face or exact construction station. Physical front and wall cut remain withheld.

zero_thickness_analytical_entrance_center_XYZ.z

47.344 ft

2 ft W3 trace uncertainty; not a physical host face or exact construction station. Physical front and wall cut remain withheld.

accepted_host_face_and_wall_thickness

Numeric value unresolved

W229 fixes entrance run direction and one outside enclosure X datum; neither establishes finite south host-face endpoints, wall depth or reveal construction. Physical front and wall cut remain withheld.

clear hatch east-west width

7 ft

verified local dimension. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

clear hatch north-south depth

10 ft

verified local dimension. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

south clear-hatch edge world Z

46 ft

verified one-axis control. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

Calculated from: column-71-registered-world-z, w229-e1-clear-hatch-south-edge-to-column71-axis

north clear-hatch edge world Z

56 ft

verified one-axis control. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

Calculated from: e1-gate-hatch-south-z, e1-gate-hatch-depth

east clear-hatch edge world X

Numeric value unresolved

missing axis-to-classified-edge witness. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

west clear-hatch edge world X

Numeric value unresolved

missing axis-to-classified-edge witness. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

Calculated from: e1-gate-hatch-east-x, e1-gate-hatch-width

opening edge section and floor thickness

Numeric value unresolved

type detail not registered as complete floor-opening perimeter. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

west outside enclosure face world X

-65.020833 ft

verified one-axis control. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

Calculated from: w229-control-column74-world-x, w229-e1-west-enclosure-face-to-column74-axis

west outside enclosure face south endpoint world Z

Numeric value unresolved

unclassified endpoint. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

west outside enclosure face north endpoint world Z

Numeric value unresolved

unclassified endpoint. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

west enclosure wall face-to-face thickness

Numeric value unresolved

opposite face not classified. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

finite front-to-back entrance component depth

Numeric value unresolved

no complete width-height-depth bounds for one named instance. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

finished sill bottom local Y

Numeric value unresolved

floor datum is not a checked sill bottom. Missing hatch X edges, wall thickness, host face, sill and depth prohibit a finite physical solid.

trap_door_material

Printed assembly material; does not establish all gauges.

plate_surface

Top section leader identifies checkered steel plate; thickness token unresolved.

opening_view_direction

Underside plan direction; do not reverse leaf/handle interpretation.

elevator_2_leaf_count

1 leaf

Note explicitly names elevator 2. Generic depicted pair must not be copied to elevator 2.

handle_type

Plan leader identifies drop handles; dimensions and exact quantity for elevator 2 unresolved.

steel_plate_thickness

Numeric value unresolved

Null preserves unreadable fraction; no fabricated gauge.

trap_frame_angle_size

Numeric value unresolved

Three-component angle notation requires another source; no nominal size accepted.

jamb_masonry_chain_segment

8 in

Printed chain across hatched masonry in first-floor jamb detail. Local witness classes still require independent classification.

jamb_outer_chain_segment

4.75 in

Separate upper chain token; endpoints retained as source-local, not operating door width.

jamb_inner_chain_segment

3.875 in

Fraction appears 3⅞; preserve pending reading separately until independent high-resolution transcription.

sill_material_surface

Material/surface callout beneath typical first-floor elevator 1/2 sill.

head_angle_first_leg

3 in

Three-component head-angle callout, visible at bottom of upright trap master crop. First leg only; no operating opening dimension.

head_angle_second_leg

3.5 in

Separate property from the same printed angle callout.

head_angle_thickness

0.375 in

Angle stock thickness; not door leaf thickness. Companion IMG_1131 has a separate recorded exposure of this notation.

head_detail_applicability

Title beneath head section limits the angle to this first-floor detail; does not infer every elevator head shares it.
