Except as otherwise provided in Section 9-2-113 of the Illinois Municipal Code, as now or hereafter amended, the committee of local improvements may reject any and all proposals or bids should they deem it best for the public good. If the committee is of the opinion that a combination exists between contractors, either to limit the number of bidders, or to increase the contract price, and that the lowest bid is made in pursuance thereof, the committee shall reject all proposals or bids. The committee may reject the bid of any party who does not have sufficient financial responsibility, equipment or manpower to perform the contract, or who has performed unsatisfactorily in completing other projects for the district. It shall reject all proposals or bids other than the lowest regular proposals or bids of any responsible bidder and may award the contract for the specified work or improvement to the lowest responsible bidder at the prices named in his bid. Such an award shall be recorded in the record of its proceedings. Such an award, if any, shall be made within 90 days after the time fixed for receiving bids or such longer or shorter period of time as may be specified in the district's bid documents.
If no award is made within that time, another advertisement for proposals or bids for the performance of the work, as in the first instance, may be made, and thereafter the committee shall proceed in the manner above provided in this Act. Such a readvertisement shall be deemed a rejection of all former bids, and thereupon the bonds corresponding to the bids so rejected shall be returned to the proper parties. However, the check or bid bond accompanying any accepted proposal or bid may be retained in the possession of the district until the contract for doing the work, as hereinafter provided, has been entered into by the lowest responsible bidder. But if that bidder fails, neglects or refuses to enter into a contract to perform the work or improvement, as provided in this Act, the bond accompanying his bid and the amount therein mentioned, shall be declared to be forfeited to the district and shall be collected by it and paid into its fund for the repairing and maintenance of like improvements. Any bond forfeited may be prosecuted and the amount due thereon collected and paid into the same fund.
