This type of contract covers damage to third parties caused by all construction or public works operations. It allows a client to have a uniform insurance cover on his site. This cover differs from the construction site insurance which covers damage to the site.

The decennial insurance is another derivation of the risks of building site liability. This type of insurance guarantees:

• 1. The strength of the work;
  2. impropriety at the destination;
  3. the strength of the indissociable equipment elements;
  4. collapses resulting from a construction defect.
  5. It also applies to new constructions undertaken by individuals.
