Abstract: The disputes regarding construction contracts of great economic importance are usually entrusted to a board of arbitrators rather than to civil courts because of the greater velocity of arbitration compared to the length of ordinary process. However, even arbitration takes time to prepare the case and to allow the arbitrators to decide who is right and who is wrong. Due to this, mainly in big contracts, a completely different logic is evolving: to prevent the dispute and to solve it through a stable body (made of lawyers, engineers, geologists, etc., according to the contract’s nature) provided by the contract in order to face and solve problems as they occur, and to allow continuation of the execution. In such context, therefore, arbitration and ordinary process would be used only if the board has failed to solve the dispute.
