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.

Unresolved extraction work
  • other structural schedules
  • unrelated wall/footing details
  • full plan dimension and reinforcement audit
  • Remaining individual dimensions, service/member instances, schedules, material and connection details require source review.
  • Original/revised annotation authority and companion registrations remain unresolved.
  • Architectural geometry and installed quantities are not established by service underlays.
  • Remaining individual dimensions, service instances, fine callouts and routes require source review.
  • Original/revised annotations, companion sheets and installed registration unresolved.
  • Architectural geometry and installed quantities are not established; model unchecked.
  • Beam width/depth numbers and stirrup sequence units remain unlabeled in this table; no unit guessed.
  • Beam straight/bent/top rod fractions remain too soft for a fully verified row-by-row transcription.
  • Table quantities are type components, not building-wide installed quantities.
  • 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.
  • Full source-to-building registration, installed quantities and as-built correspondence remain unresolved.
  • Complete notes, schedules, callouts, margins and colored revision authority outside listed regions await review.
  • Extraction remains partial; modeling/checking unchecked. No irrecoverable evidence conclusion.
  • Full concrete beam/slab schedule row extraction
  • Companion details, revisions and member assignments
  • Complete source-to-plan registration and installed-instance applicability remain unresolved.
  • Unreviewed sheet regions, notes, callouts, schedules and revision authority remain open.
  • Material grades, full profiles, connection capacities and independent modeling checks unresolved.
  • 1/5 clear-span top bend and3/4 effective-depth separation close four repeated null clause questions only.
  • Unlabeled beam width/depth and stirrup-sequence units remain unknown; type-component counts do not establish installed quantities.
  • 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.
  • Beam WIDTH/DEPTH header still has no independently established physical unit. Adjacent slab DEPTH inch marks are in a different table and do not authorize beam units.
  • No dimensional closure from repeated unitless numeric glyphs; all beam width/depth unit questions remain open.
  • 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.
  • No world geometry, material grade, structural capacity or model acceptance established.
