Commercial Property Claim Scenario: Marine Construction Contractors

A marine construction contractors operation completed work that developed water intrusion six months later. The completed operations claim included $88,000 in remediation and $35,000 in interior repairs.

Without proper commercial property coverage, this loss would come directly from business assets. The right policy covered defense costs, damages, and esolution management — allowing the business to continue operating.

Does Your Commercial Property Policy Actually Cover This? A Guide for Marine Construction Contractors

marine construction contractors often assume their commercial property policy covers more than it does. Here is a practical guide to what is — and is not — covered:

Covered: A client’s employee is injured by your marine construction contractors operations → yes, GL bodily injury. Your equipment damages a client’s property → yes, GL property damage. A completed project fails and causes damage → yes, completed operations (if your policy includes it).

Not covered: Your own employee is injured → no, that is workers comp. Your own equipment is damaged → no, that is inland marine or property. A client claims your professional advice was wrong → no, that is E&O. Pollution from your operations contaminates a neighbor → no, that is environmental liability.

The distinction matters because a denied claim costs you the full loss out of pocket — plus the premium you paid for coverage that did not apply.

What documentation and compliance does Commercial Property require for Marine Construction Contractors?

Maintaining proper commercial property documentation is a compliance requirement for marine construction contractors — not just good practice. These are the documentation standards you must maintain:

Certificate of insurance: Issued on ACORD 25 form, showing current commercial property limits, policy numbers, and ndorsements. Most client contracts require updated COIs annually and upon renewal.

Endorsement verification: Additional insured endorsements, waiver of subrogation, and rimary/noncontributory language must be actually attached to your policy — not just listed on the certificate. Verify each endorsement exists on the underlying policy.

Regulatory compliance: OSHA 29 CFR 1926 (Construction standards), 29 CFR 1915-1918 (Maritime standards — may apply depending on operations), USACE permit requirements for waterway construction, and Coast Guard navigational safety requirements. Insurance compliance and regulatory compliance are linked — OSHA violations can trigger carrier audits and premium adjustments.

Claims reporting: Report all incidents to your carrier immediately, even if you believe no claim will result. Late reporting is the most common reason carriers deny otherwise-covered claims for marine construction contractors.

What questions should Marine Construction Contractors ask before binding Commercial Property?

Before you bind your commercial property policy, ask your advisor these questions to ensure the coverage actually matches your marine construction contractors operations:

1. Is this occurrence-based or claims-made? For marine construction contractors, occurrence-based coverage provides broader long-tail protection. If claims-made, confirm the retroactive date covers all prior work.
2. Does completed operations coverage extend for the full statute of repose? For marine construction contractors, claims can surface years after work is finished.
3. Are additional insured endorsements included by blanket or must each be scheduled? Blanket AI (CG 20 10) is more efficient for marine construction contractors with multiple clients.
4. What is the aggregate limit structure? Per-project aggregates (CG 25 03) prevent one large claim from consuming the limit for all your projects.
5. Does the carrier have a dedicated claims team for your industry? Specialist claims handling resolves marine construction contractors claims faster and at lower cost.
