WHAT CIVIL ENGINEERING INSURANCE MAY NOT COVER

Why Understanding Exclusions Is Critical

Many claims are declined not because a contractor lacks insurance, but because the activity falls outside policy scope. Civil engineering involves higher-risk works that are often restricted, excluded or require specialist extensions.

Common Exclusions in Civil Engineering Policies

These exclusions frequently apply unless specifically insured.


  • Deep excavations, piling and underpinning works
  • Pollution, contamination and gradual environmental damage
  • Design responsibility without PI insurance
  • Defective workmanship and rectification costs
  • Vibration, subsidence and ground movement
  • Damage to adjacent or neighbouring property

Policy-Specific Exclusions to Watch

Exclusions vary by cover type and insurer.


  • Public liability pollution exclusions
  • Contract works depth or value limits
  • Plant theft without approved security
  • Uninsured hired-in plant liabilities
  • Professional indemnity retroactive dates
  • Wear, tear and mechanical breakdown

How to Avoid Coverage Gaps


  • Disclose full scope of works and methods
  • Arrange specialist extensions where required
  • Review contract requirements before work starts
  • Ensure PI matches design responsibility
  • Use insurers experienced in civil engineering risk
