N.D. Cent. Code § 40-33.1-07: Construction contracts

An authority shall let contracts for construction in the same manner, so far as practicable, as is provided by law for contracts of cities except that if the estimated expense of a contract does not exceed five hundred dollars, such contract may be entered into without public letting. Nothing in this section shall be construed to limit the power of an authority to do any construction directly by the officers, agents, and employees of the authority.
