A certificate of insurance is not coverage for project owners and GCs

A certificate of insurance confirms that a policy existed when the certificate was issued. It does not amend policy terms, create additional insured status, or replace the endorsements general contractors and project owners usually require. Across southeast jobs, the documents that matter are the additional insured endorsements themselves—commonly forms in the CG 20 10 and CG 20 37 families—read against the subcontract, the schedule of forms, and the definitions that govern who is an insured.

Why does a certificate of insurance fail as proof of protection?

Certificates are administrative snapshots. They can list limits, carriers, and policy numbers. They may note that a party is listed as an additional insured. They do not change the policy. When a claim arrives years after substantial completion, adjusters and coverage counsel look to the policy, the endorsements in force for the relevant period, and the contract that triggered the request—not the PDF emailed at notice to proceed.

Owners and GCs who treat the certificate as the finish line often discover gaps only after a tender: the wrong endorsement edition, blanket language that never reaches the required party, a primary-and-noncontributory ask that was never granted, or completed-operations protection that ended when only an “ongoing operations” form was issued.

What do CG 20 10 and CG 20 37 usually address?

In many commercial general liability programs, CG 20 10-type endorsements are tied to additional insured status for ongoing operations. CG 20 37-type endorsements are tied to completed operations. Exact coverage still depends on the edition date, the schedule, any manuscript changes, and how “your work,” “insured contract,” and related definitions apply to the facts.

Project risk in Georgia frequently spans long punch-list and warranty periods. A program that only documents ongoing-operations additional insured status can leave completed-operations tenders contested. Stacking endorsements without matching the written insurance requirements can look compliant while the schedule still omits the owner, lender, or upstream contractor who must be protected.

Contractual risk transfer and endorsement wording should be reviewed with qualified legal counsel. Insurance placement advice is not a substitute for contract interpretation.

How should GCs and owners review additional insured requests?

1. Map the requirement to the form. Compare the subcontract or owner agreement to the actual endorsement text and edition, not only to certificate remarks.
2. Separate ongoing from completed operations. Confirm whether both are required and how long completed-operations protection must continue after completion.
3. Test primacy language. If the contract calls for primary and noncontributory treatment, verify the policy grants it for the additional insured—and how other-insurance clauses interact.
4. Watch entity names and AI schedules. Wrong legal names, missing lenders, or “as required by written contract” language that never attaches can defeat the intent.
5. Keep a renewal trail. Endorsements can change at renewal even when the certificate template looks familiar. Re-check forms when the underlying general liability policy renews mid-project.

When is completed-operations additional insured status most important?

Completed-operations disputes commonly surface after handover: alleged construction defects, bodily injury tied to finished work, or property damage discovered during occupancy. Southeast commercial and multifamily schedules often keep subcontractors and design-builders in the claim narrative long after demobilization. That timing is why owners and GCs press for CG 20 37-type protection in addition to ongoing-operations forms—and why certificate language alone is a weak control.

Common questions

Does listing someone as an additional insured on a certificate create coverage?

No. Listing a party on a certificate does not create additional insured status by itself. Coverage depends on the policy and the endorsements in force for the claim period, read with any written contract the endorsement schedule requires.

Can one endorsement edition cover every project requirement?

Not reliably. Edition dates, manuscript edits, and contract wording differ across owners, GCs, and lenders. Match each requirement to the forms actually issued for that project and policy term.

Should certificates still be collected?

Yes—as part of a file that also holds contracts, endorsement copies, and renewal confirmations. Certificates support tracking. They do not replace a review of the coverage grants.

What clients can do

• Stop treating the COI as the finish line; demand the AI endorsement PDF for ongoing and completed operations when the contract requires both.
• Check legal names on the endorsement schedule against the contract parties, including lenders where required.
• Re-verify AI forms at each GL renewal on multi-year projects.
• When a tender arrives, send the contract, the endorsement, and the complaint together—not the certificate alone.
• Put qualified legal counsel on the contract language when indemnity and AI wording disagree.
