Article 692 of Civil Code

1 - The contractor and engineer warrant against any total or partial collapse or defect in the buildings they have constructed or fixed installations they have erected, for ten years from completion of the building or installation, subject to the following articles. 2 - Nevertheless, if it is established that the contracting parties intended the buildings or installations to remain for less than ten years, the warranty shall last for the period during which they were intended to remain. 3 - The warranty covers collapse even if arising from a defect in the land itself or if the employer authorized the erection of the defective buildings or installations. It also covers defects appearing in the buildings and installations that threaten their solidity and safety.
