Questão jurídica principal
Whether the contract created an exigible monetary claim for the contractor
Decisão extraída
No. The agreement provided payment exclusively by counter-prestations in kind; the contractor had no exigible cash claim against the owner.
Fundamentação extraída
The parties’ real common intent was a mixed contract with payment by engineering services and isolation works. A cash claim would arise only if the promised in-kind performance were not rendered, which was not established here.
