Built for Every Type of
Excavation & Site Work Contractor

From single-operator excavating companies to multi-crew underground utility contractors, every operation that moves earth carries serious insurance exposure. Here's who we cover.

🚜

Excavation Contractors

You dig foundations, cut grades, and move earth for residential and commercial projects. Equipment breakdowns, utility strikes, and property damage are your daily risks.

🏗️

Site Preparation Companies

You clear, grade, and prepare raw land before vertical construction begins. Your work sets the foundation for everything above — and carries the liability to match.

📐

Grading Contractors

Precise grading work for drainage, road bases, and site leveling. Erosion, drainage failure, and equipment damage are the claims you need covered.

⛏️

Trenching Contractors

You open trenches for utilities, footings, and drainage systems. Trench cave-in liability and underground utility strikes are your primary exposures.

🔧

Underground Utility Installers

You install water, sewer, gas, electric, and telecom infrastructure. Every foot of trench you open carries the risk of striking adjacent utilities.

🌲

Land Clearing Contractors

Stumps, brush, and debris removal before excavation begins. Equipment fires, property damage, and debris disposal liability are your daily concerns.

🏠

Foundation Excavation Subs

You work as a subcontractor to GCs and builders digging foundations and basements. Your GC requires proof of insurance before you step on site.

A Full Insurance Stack
for Excavation Operations

One underground utility strike or equipment rollover can generate multiple overlapping claims. You need every layer in place before that call comes in.

🛡️

General Liability

Your core protection against third-party bodily injury and property damage claims. Excavation GL must be written by a carrier with experience in underground and heavy civil work.

  • Utility strike damage to neighbors & utilities
  • Property damage during site operations
  • Bodily injury to third parties on site
  • Completed operations coverage
  • Additional insured endorsements for GCs
  • $1M–$2M per occurrence limits available
👷

Workers' Compensation

Excavation carries NCCI Class Code 6217 — one of the higher-rated construction WC codes. Your workers face cave-in, heavy equipment, and struck-by hazards every day.

  • NCCI Class Code 6217 — excavation NOC
  • Medical treatment for injured employees
  • Lost wage replacement
  • Trench cave-in & cave-in rescue injuries
  • Heavy equipment-related injuries
  • Employer's liability coverage included
🚛

Commercial Auto

CDL-required dump trucks, excavator transport lowboys, water trucks, and service vehicles need commercial auto coverage — not personal auto policies.

  • Dump trucks & CDL operator coverage
  • Lowboy & equipment transport trailers
  • Non-owned & hired auto coverage
  • Onsite vehicle movement coverage
  • Hired subcontractor vehicle coverage
🔩

Inland Marine (Equipment)

Excavators, bulldozers, loaders, and graders are your business. Inland marine equipment coverage protects your iron whether it's on a job site, in transit, or in the yard.

  • Scheduled equipment to replacement value
  • Excavators, dozers, loaders, compactors
  • Rented & leased equipment coverage
  • Theft, vandalism & accidental damage
  • Equipment in transit on lowboys
  • Attachments & hydraulic tools covered
⚗️

Contractors Pollution Liability

Standard GL policies exclude pollution claims. When you strike an underground fuel tank, disturb contaminated soil, or breach a gas main, CPL is what pays the cleanup.

  • Underground storage tank (UST) strikes
  • Contaminated soil disturbance claims
  • Gas main breach & gas leak events
  • Third-party bodily injury from exposure
  • Environmental cleanup & remediation costs
  • Regulatory defense & compliance costs
☂️

Umbrella / Excess Liability

A single catastrophic utility strike or trench collapse can exceed your primary GL limits. Umbrella coverage layers on top of your GL, WC, and commercial auto for major events.

  • Layers above your primary GL policy
  • $1M–$10M+ umbrella limits available
  • Required by many GC contracts
  • Follows form over underlying policies
  • Cost-effective catastrophic protection

What a Claim Actually
Looks Like on an Excavation Job

Example Claim

The Unmarked Gas Main Strike

An excavation crew is digging a residential foundation in a suburban neighborhood. The 811 locate was called and markings were on the ground, but an aging gas distribution main 18 inches from the marked line wasn't in the utility records — it was installed before systematic mapping was required.

The excavator bucket clips the main. Gas escapes immediately. The crew evacuates, the fire department shuts down the block, and the neighboring house is evacuated for 36 hours while the utility makes emergency repairs. The gas ignites near a pilot light in the neighboring home causing partial structural damage.

Final tally: utility emergency repair costs, neighboring property structural damage, emergency response fees, and the property owner's displacement costs total $340,000. The utility owner and neighboring homeowner both file claims. The contractor faces a lawsuit with pollution allegations attached because the gas release constitutes a pollutant under the GL policy's pollution exclusion.

Without GL + Pollution Liability: The contractor's standard GL denies the gas release component under the pollution exclusion. The contractor faces a $340,000 judgment personally — potentially forcing bankruptcy.
With GL + CPL: The general liability policy covers the property damage and bodily injury components. The Contractors Pollution Liability policy covers the gas-release environmental claim and legal defense. The contractor pays their deductible. Operations resume.

We Know Excavation Insurance
the Way You Know Dirt Work

Most generalist brokers can't find carriers that write excavation — it's a specialty class. We work with carriers that understand utility strike liability, NCCI Class 6217 workers' comp, and the full risk profile of underground work.

01

Excavation-Specific Carrier Access

We work with admitted and E&S carriers that actually write excavation GL — not carriers who decline the class or exclude underground work with broad endorsements.

02

Pollution Coverage Included

We don't let you leave the table without understanding your pollution exposure. CPL is a standard recommendation for every excavation contractor we insure.

03

Equipment Value Matched to Reality

We schedule your equipment at current replacement value — not depreciated book value. When your excavator gets stolen, you need to replace it, not get a fraction of what it's worth.

04

All 50 States, Fast Turnaround

We're licensed nationally. Most excavation contractor quotes are back within one business day. New project starting Monday? We'll get your COI in time.

05

GC-Required Certificates Handled

We issue additional insured certificates same-day. When your GC needs to see your COI before the excavator rolls on site, we make that happen without delays.

06

Talk to a Licensed Agent

You speak directly with a licensed professional who understands the excavation industry — not a web form, not a call center. Real answers about what's covered and what's not.

Excavation Contractor Insurance
Questions — Answered

The coverage questions we hear most from excavation contractors, trenching companies, and underground utility installers.

Yes, if you carry the right GL policy. Striking an unmarked or mismarked utility line — gas, electric, fiber, or water — is one of the most common and costly claims in excavation work. Your general liability policy covers third-party property damage and bodily injury resulting from the strike. If the damaged line causes pollution (gas leak, fuel release), a Contractors Pollution Liability (CPL) endorsement or standalone policy covers the environmental cleanup and related claims. Always call 811 before digging — insurers can deny coverage for utility strikes when no locate was called.
NCCI Class Code 6217 is the standard workers' compensation classification for excavation or grading contractors, including not-otherwise-classified (NOC) site preparation work. It carries a high experience modification factor base because of the elevated injury risk from trench cave-ins, heavy equipment operation, and falling debris. If your crews do multiple types of work (grading, utilities, demolition), your policy may carry multiple class codes. Getting this classification right matters — miscoding can lead to a premium audit surprise or a claim denial.
It depends on how the inland marine policy is written. A scheduled equipment floater covers specific owned machines listed on the policy. If you regularly rent excavators, dozers, or other heavy equipment, you need a "rented equipment" or "contractor's equipment — leased/rented" endorsement, or a separate rented equipment coverage form. Some rental yards require a certificate of insurance naming them as additional insured and confirming coverage for rented equipment before releasing the machine. We structure your inland marine to match how you actually operate — covering both owned and rented iron.
Calling 811 before you dig is legally required in all 50 states and is your first line of defense — but it does not eliminate liability entirely. If you called 811, the locate was performed, and the utility was incorrectly marked, liability typically shifts to the locating company or utility owner. However, if you dig in an unmarked area without a locate, outside the tolerance zone, or before the required waiting period expires, your GL insurer may deny the claim. Documenting your 811 ticket number, the locate date, and the painted markings with photos is critical for any claim defense.
Yes. Almost every general contractor requires a certificate of insurance (COI) naming them as additional insured on your general liability policy before allowing you on site. Many GC contracts also specify minimum GL limits ($1M or $2M per occurrence), workers' comp, and commercial auto. Once your policy is bound, we issue COIs same-day with the additional insured endorsement. We keep your certificate on file and re-issue whenever a new GC or project owner requires one.
Contractors Pollution Liability (CPL) covers claims arising from the release, dispersal, or migration of pollutants as a result of your contracting operations. For excavation contractors this includes: accidentally releasing underground fuel storage tank contents, disturbing contaminated soil that releases volatile organic compounds, striking a gas line that causes a gas leak, or excavating near a site with unknown contamination. Standard GL policies have a "pollution exclusion" that excludes most of these scenarios. CPL fills that gap and covers cleanup costs, third-party bodily injury from exposure, property damage, and legal defense.
If a worker is your employee, their injury is handled through workers' compensation — not general liability. Workers' comp covers medical treatment and lost wages regardless of fault, and it's your exclusive remedy, meaning the injured worker typically cannot sue you directly. However, if the injured worker is a subcontractor's employee, or if a third party is harmed by a trench collapse, your general liability policy responds. OSHA Subpart P mandates cave-in protection for trenches 5 feet or deeper — an OSHA violation at the time of a collapse can complicate your claim and result in regulatory fines on top of the insurance claim.
Bonding requirements vary by state, county, and the type of work you perform. Many states require a contractor's license bond to obtain or renew a contractor's license — these typically range from $5,000 to $25,000. If you work on public works or government contracts, a performance and payment bond (P&P bond) is typically required at 100% of the contract value. Bonding is separate from insurance — it's a financial guarantee of contract performance, not a liability protection product. We can help coordinate bonding alongside your insurance program.
