For each tranche awarded, where the amount of the advance payment is less than 80% of the amount of the tranche inclusive of all taxes, its reimbursement must be completed when the amount of the services performed by the contractor reaches 80% of the amount of the tranche awarded inclusive of all taxes.
In other cases, if the contract is silent, the advance is reimbursed in full when the amount of the services performed, including all taxes, reaches the amount of the advance granted.
