Questão jurídica principal
Whether the contractor was entitled to an additional CHF 50,000 for moving the site installation under the construction contract
Decisão extraída
No entitlement was shown because the contractor failed to prove the necessity of the additional work or a valid agreement on the supplement.
Fundamentação extraída
Under Art. 373 CO and Art. 374 CO, a fixed price can be increased only if the contractual modification or the necessary additional costs are proven. The factual findings did not establish that the access had to be changed or that the alleged extra costs were necessary.
