Installation Floater Buying Guide for Tunneling Contractors

When shopping installation floater for your tunneling contractors business, evaluate each quote against these criteria:

Coverage form: ISO CG 00 01 (occurrence) is the standard. Non-standard or manuscript forms may contain restrictions. Ask for the policy form number before binding.

Defense provision: Does defense erode the policy limit, or is it paid in addition to limits? “Defense outside limits” provides significantly more protection for tunneling contractors.

Exclusion review: Read every exclusion. For tunneling contractors, pay particular attention to pollution, professional services, and are/custody/control exclusions.

Carrier specialization: A carrier that writes hundreds of tunneling contractors accounts understands your risk better than one quoting your class for the first time. Ask how many similar accounts the carrier currently writes.

What other coverages should Tunneling Contractors carry alongside Installation Floater?

Installation Floater is one component of a complete insurance program for tunneling contractors. These additional coverages fill the gaps that installation floater does not address:

• Workers Compensation — covers employee injuries that installation floater excludes. Mandatory in nearly all states for tunneling contractors with employees.
• Commercial Auto — covers vehicle-related liability excluded from installation floater. Essential for tunneling contractors who operate fleet vehicles.
• Umbrella/Excess Liability — extends your installation floater limits when a large claim exceeds the primary policy. We recommend a minimum $1M umbrella for tunneling contractors.
• Inland Marine/Equipment — covers tools and equipment that installation floater and property policies exclude when located off-premises.

A coordinated program where all coverage lines work together provides better protection than any single policy. Coverage Axis builds these multi-line programs for tunneling contractors as a standard practice.

When does Installation Floater respond — and when doesn’t it?

Understanding exactly when your installation floater policy activates helps tunneling contractors avoid the most costly misunderstanding in insurance: believing you are covered when you are not.

The policy responds when: a third party suffers bodily injury or property damage caused by your tunneling contractors operations, during the policy period, within the coverage territory, and he incident does not trigger a specific exclusion. Defense costs are covered in addition to (or within) the policy limits depending on the form.

The policy does NOT respond when: the damage is to your own property (requires commercial property coverage), the injured party is your employee (requires workers compensation), the claim arises from professional advice (requires E&O), or the incident involves pollution (requires environmental liability). Each non-covered scenario requires a different policy — which is why tunneling contractors need a coordinated multi-line program, not just a single installation floater policy.

How Tunneling Contractors Are Classified for Installation Floater

Insurance carriers classify tunneling contractors using standardized systems that determine base rates:

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)

These classifications are not arbitrary — they reflect actuarial loss data. Tunneling operations carry the highest severity potential in construction — a single tunnel collapse can generate casualties and claims exceeding $10 million. The fatal injury rate for tunneling is approximately 3× general construction (Source: BLS CFOI, OSHA) Carriers that specialize in tunneling contractors understand these classifications deeply and can often identify savings opportunities that generalist agents miss.
