The Authority may contract for the planning, acquisition, construction, operation, maintenance, repair, extension, and improvement of any project, or may contract with other public or private owners of any project to perform these functions, without advertising for bids, preparing final plans and specifications in advance of construction or securing performance and payment bonds, except to the extent that the directors determine that these actions are desirable in furtherance of the purposes of this chapter. Except as otherwise provided by this section, no contract shall be invalid or unenforceable by reason of nonperformance of the conditions required by any other law relating to public contracts. (Added 1979, No. 78, § 3.)
