Except as otherwise provided in Section 9-2-113 of the Illinois Municipal Code, as now or hereafter amended, if such original bidder fails or refuses to enter into a contract, which shall be simultaneously executed by the district and signed by the chairman of the committee of local improvements and attested by the district's clerk under the district's seal, then the committee without further proceedings may again advertise for proposals or bids as in the first instance and award the contract for the work to the then regular lowest bidder. The bids of all persons who have failed to enter into the contract as provided in this Act shall be rejected in any bidding subsequent to the first for the same work and in no event treated as the regular lowest bidder.
