The board of county commissioners, in case of each improvement ordered by it, shall designate the place of beginning and the direction in which the work must proceed, and shall require the same to be completed mile [1.61 kilometers] by mile [1.61 kilometers] or in parts of miles [kilometers] continuously, as ordered, and no payment may be made except for work so completed. It also may require the supervision of the work by the county surveyor, so far as deemed necessary, and shall require the county surveyor to compute and estimate the amount of completed work and to certify the same to the county auditor at the end of each month, and all the work contracted for must be completed prior to the first day of November next following.

24-05-04. Contracts to be advertised - Road construction - Requirements for rental contracts. 1. If a contract for a highway improvement exceeds two hundred thousand dollars, the board of county commissioners shall seek bids by publishing an advertisement at least once each week for two consecutive weeks in the official newspaper of the county and in other newspapers as the board deems advisable. The first publication must be made at least fifteen days before the day set for the opening of the bids. For any contract for a highway improvement that exceeds fifty thousand dollars but does not exceed two hundred thousand dollars, the county, when possible, shall seek quotes from at least two contractors. If a road is destroyed by a flood or other casualty and the public interest would suffer by the delay from advertising for bids and awaiting the contract, the county commissioners may promptly contract for the rebuilding or repair of the road without advertising for bids, regardless of the cost. 2. Except as provided in section 54-44.4-13, a purchase of county road machinery and any rental contract or agreement for the use of road machinery and other articles, except necessary repairs for road machinery, which exceeds the sum of one hundred thousand dollars must be advertised by publishing an advertisement for bids at least once each week for two consecutive weeks in the official newspaper of the county and in any other newspapers as the board deems advisable. The first publication must be made at least fifteen days before the day set for the opening of the bids. The board of county commissioners may not enter a rental contract or agreement for the use of road machinery and other articles for a longer period than twelve months from the date of the rental contract or agree to pay rental for the use of road machinery and other articles which would result in the lessor receiving rental at a rate in excess of twenty percent per year of the cash sale price of the road machinery or other articles. The cash sale price of the road machinery and other articles must be clearly set forth in any rental contract for road machinery and other articles and failure to include this data in any rental contract for the use of road machinery and other articles renders the rental contract void. A payment made under a void rental contract is recoverable from the county commissioners making the contract, jointly and severally. 3. Notwithstanding the provisions of this section relating to the duration of rental contracts, the board of county commissioners may enter lease-purchase agreements
for the road machinery and articles covered by this section if those agreements provide for the complete performance and full payment of the purchase price of the machinery or articles within seven years from the date of the execution of the lease-purchase agreement according to section 44-08-01.1. 4. Notwithstanding the provisions of this section relating to bidding of road machinery, the board of county commissioners or its designee may purchase used road machinery at public auction or as surplus property from the office of management and budget. 5. Bids received under this section must be opened and awarded under the procedure provided in section 48-01.2-07.
