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.

Ground collapse and cave-in, respiratory hazards from dust and gases, struck-by from tunnel boring equipment, flooding, and ire/explosion from methane or other trapped gases.

These numbers explain why carriers charge the rates they do for tunneling contractors — and why proper coverage configuration matters more than premium price.

How Tunneling Contractors Are Classified for Contractors Tools & Equipment

Your WC classification under NCCI 6251 (Tunneling — all operations) — one of the highest-rated NCCI classifications reflects the hazard level of your primary operations, with base rates of $16.40–$30.20 per $100 of payroll. Your GL classification under ISO GL class code 91580 (Tunneling contractors) determines how your liability premium is calculated. (Source: NCCI, ISO)

What Contractors Tools & Equipment Does NOT Cover for Tunneling Contractors

Understanding exclusions is as important as understanding coverage. Standard contractors tools & equipment policies for tunneling contractors typically exclude: intentional acts (damage you cause deliberately), contractual liability beyond insured contracts, pollution and environmental damage (requires separate environmental policy), and professional errors (requires E&O coverage).

For tunneling contractors specifically, watch for care, custody, and ontrol exclusions that limit coverage for property in your possession, employee injury exclusions (handled by workers comp, not contractors tools & equipment), and auto-related exclusions (handled by commercial auto). Each gap requires a separate policy or endorsement — which is why your contractors tools & equipment program must be coordinated across all coverage lines.
