AI + BOQ + BIM Full Pipeline Demo — NexAI Labs

Описание: A senior QS professional raised three sharp concerns about my previous AI + BOQ demo. He was right on two of them. This video addresses all three — live, on screen, with the corrected workflow.

This is the full industry-aligned pipeline from IFC BIM file to QRA-ready Risk Register. Every step shown live. No shortcuts.

WHAT THIS VIDEO COVERS
─────────────────────────────────────────────

✅ CONCERN 1 CLOSED — "You can't prepare a BOQ purely from BIM"
The demo now shows concept-stage extraction as a starting point. The AI flags what's missing. The QS completes it. That's the workflow.

✅ CONCERN 2 CLOSED — "BIM models are never 100% updated"
Stage 0 (Model Currency Check) now runs before every extraction — model date, LOD level, MEP status, design freeze confirmation. If the model isn't current, extraction stops.

✅ CONCERN 3 ADDRESSED — "How do you do risk analysis from just a BOQ?"
Standard QS methodology. The demo extends to Stage 6 — a QRA-ready Risk Register with Min / Most Likely / Max cost columns. These are the P3 triangular distribution inputs for Monte Carlo simulation in @RISK or Primavera Risk Analysis.

THE FULL PIPELINE — 7 STAGES
─────────────────────────────────────────────

Stage 0 — Model Currency Check (LOD · date · design freeze)
Stage 1 — IFC / BIM Model (3dviewer.net · Al Rayyan Tower)
Stage 2 — Auto BOQ Extraction (Python · IfcOpenShell)
Stage 3 — LLM Council (GPT-4 · Gemini · Claude — 3 real AIs, 3 browser tabs)
Stage 4 — Chairman Synthesis (AI QS Review Council)
Stage 5 — Risk Report + Register (GO / NO-GO verdict)
Stage 6 — QRA Risk Register (P3 inputs for Monte Carlo simulation)
