(A) AWARD AND EXECUTION OF CONTRACTS. Except as otherwise provided in this Section, the Mayor, or if so designated by the Mayor the City Manager, shall award and execute all contracts on behalf of the City.
(B) COMPETITIVE BIDDING. Council, by ordinance, shall establish a threshold amount, notice provisions and other procedures for competitive bidding. When any contract for the construction of a public improvement or the purchase of equipment, supplies, or materials is estimated to exceed the threshold established by Council, the contract shall be competitively bid unless exempted under 8.02(C). Council shall award a contract to the lowest and best bidder, provided that Council may reject any and all bids in whole or by items. No contract shall be divided to avoid the requirements of competitive bidding.
(C) WAIVER OF COMPETITIVE BIDDING. By a vote of no less than five members, Council may waive the competitive bidding requirement; if Council determines that an item is available and can be acquired only from a single source; or if Council determines that a waiver of the competitive bidding requirement is in the best interest of the City.
(D) PROJECT DELIVERY. The Mayor shall select the project delivery method that in the Mayor's sole discretion is in the best interest of Obetz and may include-without limitation-design build, single prime contracts, or any other method of project delivery.
(E) NO INTEREST OR ESCROW. Notwithstanding any provision of general law, contractors and vendors shall not be entitled to receive interest on funds temporarily retained on a contract pending final acceptance of work performed or goods supplied, nor shall the City be required to maintain a separate escrow account from which to pay any contractor or vendor.
(F) PROFESSIONAL SERVICES. Contracts for professional services shall not be subject to the competitive bidding requirements of this Section and shall not require authorization by Council if the current operating budget provides sufficient funding for the scope of services in any such contract.
(G) ALTERATIONS OR MODIFICATIONS OF CONTRACTS. Council shall establish procedures for alterations or modifications of contracts. Modifications or alterations of contracts shall not require competitive bidding.
(H) CERTIFICATION OF FUNDS. No contract involving the expenditure of money shall be entered into or authorized by the City Manager unless the Director of Finance or designee shall first certify that:
(1) funds required for the contract are in the City’s treasury or in the process of collection; and
(2) funds have been appropriated by Council and remain unencumbered.
(I) The Director of Finance shall file and record the certification of availability and appropriation of funds in the accounting records of the City and shall furnish a copy to the vendor or contractor. Without the certification, a contractual obligation shall be void and unenforceable against the City unless recognized by Council as a moral obligation.
