Deductible
Deductibles are typically used to deter the large number of claims that a consumer can be reasonably expected to bear the cost of. By restricting its coverage to events that are significant enough to incur large costs, the insurance firm expects to pay out slightly smaller amounts much less frequently, incurring much higher savings. As a result, insurance premiums are typically cheaper when they involve higher deductibles. For example, health insurance companies offer plans with high premiums and low deductibles, or plans with low premiums and high deductibles. One plan may have a premium of $1,087 a month with a $6,000 deductible, while a competitive plan may have a premium of $877 a month with a $12,700 deductible. The consumer with the $6,000 deductible will have to pay $6,000 in health care costs before the insurance plan pays anything. The consumer with the $12,700 deductible will have to pay $12,700.
Decennial liability
Decennial liability insurance or "Inherent Defect Insurance" is insurance that is taken out (by the contractor or principal) to cover costs associated with the potential collapse of the building after completion. The names derives from the fact that it covers the 10 year period after completion of the project. It is compulsory to insure in a few countries such as France, and Egypt. In other countries like Qatar there is the form of strict liability arising from the French Civil Code which does not require any proof of fault, but there is no compulsory requirement to insure The cost of the insurance can significantly increase construction costs and may be up to 1.5% of structural value (including the Technical Inspections that the insurers mandate).
