Excavation subcontractor insurance requirements for general contractors
Excavation and earthwork subs face underground utility strikes, collapse, and pollution exposure. GC programs often require higher GL limits and may require pollution or underground coverage on larger civil and site work.
Utility damage and soil movement claims justify elevated limits and pollution endorsements on major site packages.
Typical commercial limits (Excavation, $1M-$5M projects)
Starting points aligned with common 2026 GC program practice. Verify against your subcontract and owner insurance exhibit.
