The price of the works

The price of the works can be determined based on the unit measure of the contracted works (unit price) or as a total amount for the entire object (total contracted price).
If the contract does not specify otherwise regarding price adjustments, the contractor who has fulfilled their obligations within the agreed-upon timeframe can request an increase in the price of the works if the costs of the elements on which the price of the works is determined have increased during the period between the contract’s conclusion and its fulfillment, resulting in the need for the price to be higher by more than two percent. In the event that the contractor, due to their own fault, did not complete the works within the contractually stipulated period, they can request an increase in the price of the works if the costs of the elements on which the price of the works is determined have increased during the period between the contract’s conclusion and the day when the works were supposed to be completed, resulting in the need for the price to be higher by more than five percent. In cases mentioned in the previous paragraphs, the contractor can only request the difference in the price of the works that exceeds two or five percent, respectively. The contractor cannot invoke price increases based on the costs of the elements on which the price of the works is determined if the price increase occurred after their delay.
If it is agreed that the price of the works will not change in the event that the prices of the elements on which it is based increase after the contract is concluded, the contractor can still request a modification of the price of the works if the prices of the elements have increased to such an extent that the price of the works should be higher by more than ten percent. However, even in this case, the contractor can only request the difference in the price that exceeds ten percent, unless the price increase occurred after their delay.
If, in the cases mentioned in the previous clauses, the contracted price would have to be significantly increased, the employer may terminate the contract. In the event of contract termination, the employer is obligated to pay the contractor the corresponding portion of the contracted price for the work already executed, as well as reasonable compensation for the incurred necessary expenses.
If, during the period between the contract’s conclusion and the fulfillment of the contractor’s obligations, the prices of the elements on which the price of the works is based have decreased by more than two percent, and the works have been executed within the agreed-upon timeframe, the employer has the right to request a corresponding reduction in the contracted price of the works above that percentage. If the price of the works is agreed to be fixed, and they have been performed within the agreed-upon timeframe, the employer has the right to a reduction in the contracted price if the prices of the elements on which the price is determined have decreased to such an extent that the price would be lower by more than ten percent, and specifically for the difference in price exceeding ten percent. In the event of the contractor’s delay in performing the works, the employer has the right to a proportionate reduction in the price of the works for each decrease in the price of the elements on which the price is determined.
