CG 20 38 vs CG 20 33 — Automatic AI With Or Without Completed Operations
Both are automatic, contract-triggered AI forms; CG 20 38 adds completed operations, CG 20 33 doesn't.
What it actually does
CG 20 33 and CG 20 38 are both *automatic* additional-insured forms — they grant AI status to anyone the named insured has agreed in a written construction agreement to add, without scheduling each party. The difference is the timing window they cover.
CG 20 33 covers ongoing operations only. CG 20 38 covers both ongoing AND completed operations, and also reaches "other" parties the written contract requires the named insured to add (such as the owner above the GC). So CG 20 38 is effectively CG 20 33 plus completed-operations coverage plus upstream reach.
For construction, CG 20 38 is the stronger requirement because it captures the completed-operations exposure where defect claims live. A GC requiring automatic AI status should generally specify CG 20 38, not CG 20 33 — accepting CG 20 33 leaves the same completed-operations gap as accepting CG 20 10 without CG 20 37.
Verification checklist
- 01Determine which automatic form is attached — CG 20 33 (ongoing only) or CG 20 38 (ongoing + completed).
- 02If completed operations matter (they usually do), require CG 20 38.
- 03Confirm a signed written construction agreement exists (both are contract-triggered).
- 04Check the limits cap against contract-required limits.
Common mistakes
- ·Accepting CG 20 33 when the project needs completed-operations coverage — use CG 20 38.
- ·Assuming any automatic AI form covers completed operations.
Frequently asked questions
Which is better, CG 20 33 or CG 20 38?
For construction, CG 20 38 — it adds completed operations and reaches upstream parties the contract requires, while CG 20 33 is ongoing operations only.
Are both automatic forms?
Yes. Both grant AI status automatically when a written construction agreement requires it, with no party schedule. The difference is the completed-operations coverage.
