Within 30 days after the completion of the work, the committee on local improvements shall certify the fact that the work has been completed and accepted by the corporate authorities of such municipality, setting forth the total amount due the contractor for the construction of the work, the amount of the vouchers payable either in cash or bonds that have been delivered to the contractor from time to time as the work progressed, and the amount still due the contractor. The corporate authorities upon receipt of the certificate shall set a date for consideration and hearing upon the question of whether or not the work has been completed in substantial compliance with the plans, specifications and contract for the construction thereof, and shall direct the clerk to give notice of the date set for the hearing. Such notice shall be published at least once each week for 2 successive weeks in a daily or weekly newspaper published and of general circulation in such municipality, if there is such a newspaper. If there is no such newspaper, then notice shall be given by posting in not less than 4 public places in such municipality, and in at least 4 places within the boundaries of the area designated by the committee on local improvements as probably benefited by the improvement. The first publication or the first posting of such notice shall be at least 15 days prior to the date fixed for such hearing. Any person interested may, prior to the date fixed for such hearing, file written objections to the acceptance of such work, stating specifically the reasons therefor, and shall have the right to be heard at the time and place fixed by the governing body to hear and consider the same. At the time and place fixed, the corporate authorities shall hear any and all objections that have been filed in writing to the acceptance of the completed work and the corporate authorities shall have authority to continue the hearing from time to time, but for a period of not more than 30 days from the date set for such hearing, to consider written objections filed to the acceptance of the work and to give all persons an opportunity to be heard thereon. At such hearing the certificate of the committee on local improvements shall be prima facie evidence that the matter and things stated therein are true, but if any parts thereof are controverted by written objections duly filed, the corporate authorities shall hear and determine the same in a summary manner and shall enter an order according to the facts. Such order shall be conclusive upon all parties and no party shall be allowed to review or reverse the order of the corporate authorities. If upon such hearing the corporate authorities shall find the allegations of the certificate to be incorrect, it shall enter an order accordingly and it shall then be the duty of the committee on local improvements to procure the completion of such improvement in substantial compliance with the ordinance and the plans and specifications therefor. The committee on local improvements shall from time to time file additional or supplemental applications to the corporate authorities for final acceptance of the work until the corporate authorities shall eventually be satisfied that the allegations in such certificates are true and that the improvement has been constructed in substantial compliance with the plans, specification and ordinance.
