Project overview.
An agent that watches plan folders for new PDFs, runs vector diffs, maps each change to cost codes/tasks/inspections/open RFIs, and drafts one-page “Change Briefs” per trade (before/after snippet, what changed, action, due date). It pings only the affected stakeholders via text/email, requires one-tap “Got it,” rebuilds the two-week look-ahead, and updates allowances/PO drafts and cash forecasts when pricing is impacted.

Challenge.
Crews were building from outdated sheets, plan changes weren’t priced into allowances promptly, and subs learned about revisions days late—causing out-of-sequence work and margin leakage.

Result.
Impact in 30–60 days:
• “Built from the wrong set” incidents: 0 (was 2–3/quarter)
• Days saved per home: 3–7 (prevented out-of-sequence work)
• Margin leakage from unpriced plan changes recovered: +$8k–$20k/home
• Median acknowledgment time on changes: ~1.1 hours (was 24–48 hours)
