Kernrechtsfrage
Whether the cantonal court arbitrarily held that the appellant had not pursued a reduction of the architect's fee for the concrete casting of facades in his conclusions.
Extrahierter Entscheid
The canton court's reading of the conclusions was untenable; the cost-overrun claim remained included in the final submissions.
Extrahierte Begründung
The conclusions, read as a whole, still sought compensation for the cost increase caused by technical changes ordered without proper information to the client. The omission of a separate itemized amount did not amount to abandonment of that head of claim.
