Process

Fifteen minutes of structured checks catch systematic drift before spreadsheets multiply mistakes. Patterns align with how Estym8 highlights legend completeness, schedules, missing symbols — you still vet hotspots manually before sign-off.

Checkpoint patterns

  1. Legend versus dense plan sheets — sample heavy glyphs on one repeatable quadrant; reconcile the note to legend text and synonyms.
  2. "TYP." / SIMILAR callouts — multiplier applied intentionally once globally, not doubled on mirrored wings or skipped accidentally.
  3. Mirrored sets — confirm symmetrical floors are not duplicated or silently omitted when sheet numbering drifts.
  4. RCP versus floor plates — agree on the authoritative sheet for conflicting counts before reconciling deltas.
  5. Scaled segments — measure only where drawings remain true-to-scale; mark hand allowances elsewhere.
  6. Schedule roll-up vs plan counts — investigate deltas beyond tolerance; thresholds vary by commodity.
  7. Stop rule — first systemic anomaly means to widen sampling before closing bid review.

Tool alignment. The workbook shows the counts, the sheet each count came from, and the schedule roll-up. You sign off before the bid goes out.
