1. A. When any culvert or bridge is to be constructed, or grade-and-drainage project is to be developed, or reconstruction, replacement or major repairs are to be accomplished by the board of county commissioners acting alone or in cooperation with the state or federal government, at an estimated cost of Fifty Thousand Dollars ($50,000.00) or more, in either event, engineering plans and specifications shall be prepared by the county engineer to insure sound engineering practices. The project shall be advertised for bids as provided for in Section 1101 of this title, and the contract shall be let only after such notice at a public letting. If such construction work can be completed for a cost below or equal to the engineer's estimate or below any bid submitted at a public letting and so entered in its journal, nothing in this title shall prevent the board from causing the same to be built by day labor, force account, and purchase by the county of materials as provided by law.
2. B. If the board of county commissioners deems it necessary, it may consult and seek the advice of the Department of Transportation regarding the design, construction and maintenance of such project, and the Department of Transportation may furnish such advice for any of the said projects to insure sound engineering practices. If provided, such services shall be furnished without cost or expense to the county.
3. C. The board may authorize the county clerk to draw warrants for the amount of payrolls for labor furnished under the day labor system, when such payrolls are certified to as correct by the engineer or person in charge of the work, and said payroll shall be passed upon by the board following such certification.
