(a) Upon the making of the preliminary assessments, the authority shall prepare contracts and shall contract on a competitively bid basis for the acquisition, construction, or installation of all projects as specified in the petition.
(b) Because authority infrastructure projects are paid from assessments of members of the authority, no public funds may be utilized and projects shall be exempt from state bidding law, but projects should be competitively bid.
(c) The authority may not contract for and commence the acquisition, construction, or installation of one or more projects or a portion of one or more projects in advance of a preliminary or final assessment being collected.
