Key legal question
Whether remuneration for regie work under a construction contract with a cost ceiling is governed by Art. 373 or Art. 374 OR
Extracted holding
Where only a maximum price is agreed and the work is to be performed in regie, the arrangement is not a fixed-price undertaking under Art. 373 OR; the ceiling operates as a pure upper limit and remuneration is determined under Art. 374 OR.
Extracted reasoning
The parties agreed on a mixed pricing system: work was to be billed according to effort, while a cost ceiling limited the total amount. In that setting, the absence of a minimum price means there is no fixed acceptance price.
