Quick answer: Most large commercial or municipal excavation contracts request combined liability limits of $3 million to $5 million, structured as a base General Liability policy plus an Excess or Umbrella layer on top. Smaller private and residential jobs usually stay at the standard $1 million per occurrence / $2 million aggregate GL baseline with no excess requirement at all. Excavation Insurance Group sees the requested limit scale directly with contract size, proximity to utilities or occupied structures, and whether a public entity is involved.
TYPICAL LIMIT REQUESTS BY CONTRACT TYPE
| Contract Type | Common Combined Limit |
|---|---|
| Small private/residential site work | $1M / $2M GL |
| Commercial GC subcontract | $1M/$2M GL + $2M-$4M Umbrella |
| Municipal or public infrastructure work | $2M/$4M GL + $5M Umbrella or higher |
| Utility-adjacent or DOT right-of-way work | $5M combined or more |
WHY PUBLIC AND UTILITY-ADJACENT WORK PUSHES LIMITS HIGHER
Public owners and utility-adjacent projects carry stricter, generally non-negotiable insurance schedules than private commercial work, because the potential severity of a claim (a struck gas main, damage to public infrastructure, injury on a public right-of-way) is higher and the entity awarding the contract has less appetite for absorbing that risk itself. If you’re planning to bid this type of work, checking the limits requirement early, and confirming your excess or umbrella program can meet it, saves you from finding out at the bid deadline that your coverage doesn’t clear the bar.
