Installment payments shall be paid to the contractor as work progresses, in accordance with section 151.13 of the Revised Code. Progress estimates may be paid semimonthly when the amount due exceeds one thousand dollars on a contract having a value of ten thousand dollars or more. Monthly payments may be made in all other cases when the amount due is five hundred dollars or more.

Materials meeting the project specifications delivered to the job site or such other place as the engineer may approve shall be included in the progress estimate as provided in section 153.14 of the Revised Code.

The amount payable on the progress estimate shall be the grand total to date of all items of work and materials included in the bid and such approved extra items of work and materials as are furnished in accordance with the contract and accepted by the engineer, less an amount retained pursuant to section 153.12 of the Revised Code.

The amount payable so determined shall be certified by the county engineer to the board of county commissioners who shall authorize the county auditor to draw his warrant upon the county treasurer. The treasurer shall pay the warrant out of any funds in the treasury applicable to that purpose.

The final progress estimate, including the total of the retained moneys and less any liquidated damages, shall be approved by the contractor, the county engineer, and the board of county commissioners before the auditor shall draw his final warrant upon the treasurer.

The final estimate shall not be processed for payment until such time as the contractor furnishes an affidavit stating that all indebtedness incurred in connection with the contract has been paid in full.
