A construction defect damages completed work

Which repair costs are excluded as defect rectification, and which may qualify as resulting damage?

Hypothetical training case — not a reported judgment or claim determination.

Incident

A defective structural connection fails during testing and damages the connection, adjacent works, and installed equipment.

Coverage question

Which repair costs are excluded as defect rectification, and which may qualify as resulting damage?

Relevant clause

The exact LEG, DE, or bespoke defects exclusion attached to the project policy.

Insurer argument

The loss is the foreseeable cost of correcting defective design or workmanship and falls within the exclusion.

Insured argument

Only the defective element or improvement cost should be excluded; separate accidental damage to sound property should remain covered under the selected clause.

Indicative analysis

The outcome turns on the exact clause version, the physical scope of the defect, whether damage occurred, and how the repair is separated from redesign or betterment. Similar labels can produce materially different coverage.

Practical lesson

Select the defects clause deliberately before inception and document design review, testing, quality control, causation, repair scope, and improvement costs.

Claims boundary: Actual outcomes depend on the complete policy, schedule, endorsements, applicable law, evidence, causation, quantum, and claims process. Obtain professional advice for a real claim.
