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.

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.

2nd Floor Framing Plan

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

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.
