Questione giuridica chiave
Whether the construction contract price was fixed-price based on the general estimate of 9 May 1999.
Decisione estratta
The cantonal court could find, without violating federal law, that the parties intended a fixed-price contract based on the general estimate.
Motivazione estratta
The lower court relied on the contractual documents, pre-contractual context, later conduct, and the fact that the respondent could in good faith understand the listed works and price as binding. The appellant's contrary factual narrative was inadmissible in reform proceedings.
