How to Verify a 3D Model Before Bid Submission

Pre-bid 3D verification helps estimators catch scope blind spots before they become margin erosion.

1. Confirm model alignment: verify revision match with active drawings/specs and addenda.
2. Run completeness checks: inspect high-impact assemblies and trade interfaces.
3. Cross-check quantity drivers: compare major quantities to assumptions and sanity ranges.
4. Log conflicts: document constructability and sequencing concerns before final bid packaging.
5. Attach verification summary: include findings with the bid review packet.

3D Verification Checklist

• Model revision/date verified against bid documents.
• Critical assemblies reviewed for omissions.
• Major quantity drivers spot-checked.
• Conflict log and risk notes attached to review package.
