The presumption of liability established by article 1792 also extends to damage that affects the solidity of the equipment elements of a structure, but only when these form an indivisible whole with the viability, foundation, framework, enclosed or covered structures.
An item of equipment is considered to form an inseparable part of one of the viability, foundation, framework, enclosure or roof structures when it cannot be removed, dismantled or replaced without damaging or removing material from this structure.
