(b) Notice of the time and place at which competitive sealed bids or proposals must be published in accordance with the provisions of V.T.C.A., Local Government Code, §§ 252.023, 252.041, and 271.025.
(c) Bids may be opened only by the City Council at a public meeting or by an officer or employee of the city at or in an office of the city.
(d) A bid that has been opened may not be changed for the purpose of correcting an error in the bid price.
(e) If the competitive sealed bidding requirement applies to the contract, the contract must be awarded to the lowest responsible bidder. In determining who is a responsible bidder, the governing body may take into account the safety record of the bidder, of the firm, corporation, partnership, or institution represented by the bidder, or of anyone acting for such a firm, corporation, partnership, or institution if:
(1) the governing body has adopted a written definition and criteria for accurately determining the safety record of a bidder;
(2) the governing body has given notice to prospective bidders in the bid specifications that the safety record of a bidder may be considered in determining the responsibility of the bidder; and
(3) the determinations are not arbitrary and capricious.
A contract may not be awarded to a bidder who is not the lowest bidder unless before the award each lower bidder is given notice of the proposed award and is given an opportunity to appear before the governing body of the governmental entity or the designated representative of the governing body and present evidence concerning the bidder's responsibility.
(f) The city is entitled to reject any and all bids.
