Construction Insurance Basics
Key concepts:
- Cover - what the insurance policy pays for
- Exclusions - what the insurance policy does NOT pay for
- Damage - physical damage that has already occured or is imminent
- Defect - workmanship or design error that can result in damage
Not all defects and damage are created equal.
Defect clauses - LEG (London Engineering Group)
LEG 1/96 - outright exclusion (i.e. does not cover defects)
LEG 2/96 - excludes cover to the defective part, but covers damage to the non-defective parts (i.e. covers repairs to the flaw, but not the flaw itself)
LEG 3/06 - covers the defect, the resulting damage, but does not cover improvements to the design that caused the original defect to occur (i.e. all costs to reinstate as originally designed)
