Contractor’s All Risks (CAR) insurance covers material damage occurring during the works phase. It is a key estate-protection for the principal.

1. Covered risks

Fire, theft of materials, vandalism, storm, water damage, partial collapse. See also construction insurance.

2. Who subscribes?

Usually the principal (buyer). Covers all stakeholders: contractors, subcontractors, architect. Often imposed by the financing bank.

3. Cost and duration

0.1% to 0.3% of total site cost. Duration = that of the site + maintenance warranty period (usually 6-12 months after reception).
