(1) Pay interest of 1.5% per month or any part of a month to the contractor on any undisputed amount not paid on time to the contractor; and
(2) If a contractor prevails in a civil action to collect interest penalties from an owner, the contractor shall be awarded its costs and disbursements, including reasonable attorney’s fees, incurred in bringing the action.
