Sheet W401
Extraction: Reviewed · extraction partial. Partial: floor controls and first-floor perimeter frame; not a complete member or connection schedule. W401 Main perimeter beam bands, supports85–96: all visible inner and outer beam labels inventoried. W404 Main perimeter beam band, supports85–96: all visible line/pair/end-beam tags inventoried, with one end-pair profile unresolved. W401 central court/workroom roof: three identifiable members46–49 plus local dimensions; other roof members and girders are not complete. W401 light-court sections: low/high roof levels and special4-foot offset only. W404 central court boundaries and floor notes: topology and general layer notes; wall angles/channels remain incompletely extracted. W404 outside-wall sections: two location-specific stone-face offsets, not full assembly transcription. W4 Rooms 200–203 boundary and opening gate; no finite room construction authorized. Partial timed visual review: Bounded source-reading review only; no full-source or geometry acceptance. Partial timed visual review: New bounded printed-note review; full-source completeness not established. Partial timed visual review: Existing framing and light-court controls reused. Connection-type view registration added without duplicating member dimensions. Partial timed visual review: Targeted source detail only. Master orientation recorded independently from access derivatives. Region bounds are crop locators, not physical geometry. Partial timed visual review: undefined
Highlighted reading: High Point of Skylt. Roof EL.114.75. Local roof section at columns 63–64 and 65–66.

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.
- Resolve W40495–96 paired-member profile symbol before selecting section geometry.
- Register W401 and W404 independently to known columns before tracing physical boundaries.
- Complete all interior member/support identities and remaining member marks; this is not a whole-floor beam inventory.
- Resolve transverse beam offsets, section dimensions, connection locations and plate extents.
- Inspect W401 plate girders and trusses on Sh.410; lookout-gallery hangers on Sh.208; skylight/workroom and slab details on Sh.413.
- Inspect W404 light-court wall beams on Sh.402 and outside-wall sections on Sh.403.
- Extract all actual slab-edge, shaft and stair opening geometry and regional slab exceptions.
- Verify the inferred pounds-per-foot interpretation against an authoritative project section schedule or details.
- Coordinate foundations, columns and vertical continuation; do not propagate a footing position into every floor.
- Run the shared reconstruction register and tests after the reviewed adapter is integrated; no completeness acceptance is implied.
- four reviewed clear-room boundary faces and exact junctions
- door clear opening width, jambs, leaf, swing handing, head and threshold
- exterior window jamb/sill/head and assembly
- floor finish build-up and region-specific top/bottom elevations
- ceiling plane/height and finish
- all reviewed clear-room boundary faces and exact junctions, particularly the page-right recess
- verified connection and host of upper door candidate
- door clear opening width, jambs, leaf, head and threshold
- scope of FIN. NO. 1 mark and corresponding material schedule
- Visible angle digits 6 × 6 × ½ do not independently establish units for each glyph in this crop. Existing inch-valued IDs detail-20261012b-img_1315-angle_leg_1-2, angle_leg_2-3 and angle_thickness-4 remain unchanged; absence of a clear local unit mark does not disprove a prior unit convention. No withdrawal proposed.
- Complete source-to-instance registration, physical endpoints and installed quantities remain unresolved.
- Unreviewed sheet regions, fine notes, schedules, companion applicability and revision authority remain open.
- No world coordinates, member cut lengths, steel grades, physical wall geometry or architectural acceptance established.
- New companion notes do not provide member cut lengths, steel grades, angle-unit authority or a physical registration. Recent native angle glyph review is reused without repeating.
- Installed instance allocation, quantities and source-to-building registration remain unresolved.
- All remaining dimensions, profiles, joints, finishes and companion/revision applicability need review.
- No accepted physical geometry or whole-source completeness established.
- All remaining small dimension chains and endpoint classifications
- Complete profiles, quantities and installation registration
- Companion details and original/revision reconciliation
- Independent geometry/model check and as-built correspondence
- Remaining dimension endpoints and layer/material assignments not yet reviewed
- Installed instances, quantities and plan/elevation registration unresolved
- Companion details and revisions require reconciliation
- Independent model/as-built checks unavailable in this extraction
- Rivet diameters, pitches and physical hole endpoints remain unreviewed/not specified in the inspected crop.
- Companion girder/hanger notes lie outside this crop and await a separate targeted review.
- Other sheet regions, fine notes, schedules, callouts and revisions remain unreviewed.
- Complete source-to-instance registration, connection capacities, material grades and independent model/as-built checks remain pending.
