Contractor Liability for Defective Workmanship Despite Adherence to Plans

A contractual agreement stipulated that a contractor would perform work according to detailed specifications, but the resulting structure exhibited significant defects attributable to poor execution rather than flaws in the provided plans. The court ruled that despite the adherence to the technical plans, the contractor remained liable for damages because the work executed did not meet the expected standard of soundness and durability inherent in the obligation to perform the work properly, constituting a breach of the implied warranty of good workmanship, thus warranting cassation of any lower court decision that absolved the contractor based solely on adherence to the provided specifications.
