Contractor Insurance for Excavation Work

Where excavation claims come from

• Striking gas, water, power, sewer or fiber lines
• Trench collapse injuring workers
• Earth movement, settlement or drainage damage to neighbors
• Equipment rollovers and struck-by injuries
• Dump trucks and lowboy trailers on public roads

Who this applies to

C-12 earthwork and paving contractors, A general engineering contractors, pool builders, underground utility contractors, landscapers doing grading or trenching, and general contractors who self-perform site work. Carriers price by depth, equipment size and how close you work to existing utilities.

Policy wording to check

Some GL policies exclude or sub-limit underground resources and equipment damage, or earth movement. Confirm these before you bid excavation work. California excavators must also call 811 before digging, and a documented locate request helps with any utility-damage claim.

Trench safety and workers' comp

Trench collapse is one of the most serious excavation injuries. Cal/OSHA requires protective systems for trenches five feet deep or more, and carriers ask about shoring, sloping and competent-person training. A documented safety program helps both workers' comp and GL underwriting.

Before you dig

• Submit an 811 locate request and keep the ticket number
• Photograph existing conditions, curbs and landscaping
• Confirm whether the owner's private utilities are marked
• Check the GL policy for underground-resources and earth-movement wording
• Make sure every truck and trailer is on the auto policy

Equipment coverage deserves the same attention as liability. Scheduled equipment should be listed at replacement or actual cash value with serial numbers, and rented equipment needs rented-equipment coverage because most rental agreements make you responsible for the machine. Theft from unattended job sites overnight is one of the most common excavation equipment claims.

Frequently asked questions

Does GL cover hitting a utility line?

Usually, unless the policy excludes underground resources. That wording is the first thing to check.

Is my excavator covered by auto insurance?

No — heavy equipment is covered under a contractor's equipment (inland marine) policy.

Do I need a C-12 license for grading?

Earthwork and paving is the C-12 classification; A general engineering contractors also perform excavation and grading on fixed works.

Is contaminated soil covered?

Not under standard GL. Contractors pollution liability is the usual answer.
