Questão jurídica principal

Decisão extraída
Yes. The evidence showed accepted surcharges and additional work, so the negative finding was unsustainable.
Fundamentação extraída
Witness evidence established a fixed surcharge for neighborhood-related problems, other surcharges from owners' changes, and scaffold costs included in invoices.
