Extraction: Reviewed · extraction partial. Partial: floor controls and first-floor perimeter frame; not a complete member or connection schedule. Partial W409 extraction: numbered column identities and separate base-plate properties. Group headers do not establish full-height steel continuity.

Reuses existing verified frame-third-to-fourth interval; no new visual inspection.

Unresolved extraction work
- External elevation datum / benchmark is not established in this set.
- Only three absolute floor levels are directly printed and verified here: first93.25,second114.25,sixth160.25. Basement and floors3–5,7–8 are schedule-derived arithmetic, with explicit provenance.
- Schedule-derived seventh173.75 may be a raised/interior region. The parallel envelope extraction reports171.75 on another sheet. Do not collapse these into one seventh-floor level until regional geometry is reconciled.
- The parallel foundation extraction reports a boiler floor77.75; schedule basement80.25 must not override a local lowered floor.
- Roof high point195.42 is not sufficient to establish roof slopes, low points, parapets, penthouses or eave heights.
- Steel tags are offsets from floor datums; a single flat steel surface for each story is not supported. Other-story steel top elevations require their own framing sheets.
- Interior column coordinates and continuation by floor are not exhaustively transcribed. This extraction includes42 perimeter columns only.
- Photograph perspective is not rectified. Normalized regions are approximate retrieval aids only.
- Interior offset row C16–C21 depth and light-court wall faces need explicit architectural/framing dimensions; do not derive their dimensions from apparent photograph spacing.
- Column schedule describes historic design intent. These drawings alone do not establish as-built or later altered conditions.
- every steel-section fraction and plate count in 96-by-storey schedule
- all typical base/splice detail dimensions and callouts
- full interpretation of truss and girder interruption cells
- all grouped-foot offset assignments
- auxiliary S/T marks in final interior schedule column
- relationship of column tops to roof-plan details
- Section schedules are not fully transcribed. Even common-looking cells vary by group and floor.
- Some base-plate thickness fractions and offset notations are provisional; retain source photograph for independent check.
- A schedule mark identifies a column location, not a guaranteed continuous steel member from basement to roof.
- No world positions are calculated here; join to structural-registration.json using printed mark only after tracing section applicability.
- Auxiliary S/T marks visible in the final interior cell remain unresolved rather than fabricating identifiers.
- Typical exterior column base connection detail
- Typical column-splice details at right
- Base-plate table and foot-offset assignments (retained in separate column-schedule package)
- Bottom general fabrication notes and cap-plate code key
- Top I-like section diagram for E22 and its dimensions
- W410 truss/plate-girder companion sheet
- Roof/framing-plan member endpoints and continuation
- Every schedule body size cell has a record, but the fractions enumerated in sourceCoverage.partiallyTranscribedCells remain null. No neighboring-cell substitution is allowed.
- All absolute member endpoints, lengths and quantity of fabricated pieces remain unresolved. Four schedule assemblies do not prove exactly four fabricated pieces.
- C2/C3 TRUSS cells must remain discontinuities pending identification of actual truss members and bearing/column connections.
- Lower splice offsets are read for C4/C1 and the stepped C5–C9 group only; do not generalize the 2′0″ or 3′6″ offset to every exterior mark.
- The two 14×1 plates at the lower C4/C1 assemblies are transcribed as additional plates; exact cover-plate placement, length and cutoff are not assigned.
- Channel/batten sizes, rivet patterns and splice/base detail dimensions are not extracted here and are not zero.
- Seventh-floor regional level conflict remains external to this package; schedule bands must not be converted into a universal F7 slab.
- Earlier column-schedule base-plate thicknesses are not revalidated or superseded by this body-cell pass.
- Upright image regions are approximate retrieval aids; source orientation must be honored before drawing overlays.
- Sheet material establishes historical design intent only; no as-built verification or live-scene acceptance follows.
- No change to existing W409 coverage.
- Whether every floor-height schedule line applies without local exceptions at Main Street, Madison Street, courts, stairs and roof structures
- Exact column-top elevations, which W409 says vary and must be resolved from roof plans
- The documented Main-side seventh-floor elevation differs from this schedule reference and remains a separate regional datum
- The Stair E seventh-floor elevation on W226 differs from both the generic W409 schedule reference and the Main-side datum
- The basement-to-first interval conflicts with the 15-foot interval printed on W225 Stair E and must not be applied to that stair without reconciliation
- Exhaustive transcription of all W409 steel-section cells and typical connection details
- Other 95 column marks
- Complete typical base and splice fabrication dimensions
- Unresolved E′ companion Sh.411

- cap/pier transform and bearing continuity
- reinforcement layout and quantities
- material and finish confirmation
- as-built position
- Source-pick both Room 402-side and corridor-side faces at the same stations, classify finish or construction boundaries, and independently verify the printed 4-inch witness connects those faces.
- Pick the wall's two true terminations at its demising intersections; split it at the door with exact two-jamb coordinates and verify the opening width, head and threshold against a door schedule or detail.
- Close reciprocal Room 402/corridor/Room 443 face and door topology, including more than one check of the 7-foot clear corridor witness.
- Validate the frozen W-6 transform locally for classified physical faces and carry uncertainty into canonical X/Z coordinates.
- Establish the wall's physical base and top from an applicable section, ceiling/slab detail or schedule; the 137.25 finished-floor datum and 11.5-foot story interval alone do not give wall height.
- Assign applicable wall assembly and finish layers, material, rating and quantities from the relevant schedule/details.
- same-condition exterior stone to classified interior finish face depth and every intervening layer/material
- architecturally classified north/south wall ends, joints and pier returns rather than support-axis stations
- physical wall base/top and slab-edge interfaces rather than finished-floor schedule datums
- independently checked W-6 to Broadway elevation horizontal registration and B05 key/host identity
- masonry versus visible/frame/clear opening bounds, sill, head, jamb returns and reveal depth

- Connection and modeling acceptance checks
- C4 baseplate T glyph read as5¾, but no independent unit convention for the unlabeled B/L/T table was established. Physical T in inches remains unresolved.
- C4 source suffix b is not a world signed footing offset. E′ companion SH.411, seating, column top and plan transforms remain open.
- Complete source-to-instance registration, physical endpoints, installed quantities and revision authority remain unresolved.
- Unreviewed regions, companion sheets, schedules and fine fractions remain open; this package is not exhaustive coverage.
- Material grades, connection capacities, world transforms and independent model/as-built checks remain unestablished.
- The milling and cap-symbol source questions resolve; C4 section seating, top, baseplate thickness, signed footing eccentricities and installed column transforms remain open.
- 2 in milling threshold is a condition, not an individual plate thickness. 6 in cover-plate stop remains a beam-relative offset, not an absolute cutoff elevation.
- Complete source-to-instance and endpoint registration remains unresolved.
- Material grades, finishes, connection capacities and as-built checks remain unestablished.
- Unreviewed regions, fine fractions, schedules, companion applicability and revision authority remain open.
- Text-only reuse of bounded C4 T cell: 5¾ glyph already established, independent physical unit convention remains absent. No duplicate crop or closure.
- C4 angle seating, E′ companion relation, baseplate thickness units, physical column top and all world-coordinate questions remain unresolved.
- Full source-to-instance assignment, physical endpoints, installed quantities and governing revision remain unresolved.
- Unreviewed regions, notes, fine fractions and companion sheets remain open; this package is not exhaustive coverage.
