If upon the hearing the court finds against the allegations of the certificate, it shall enter an order accordingly. The board of local improvements shall then procure the completion of the improvement in substantial accordance with the ordinance. The board, from time to time, may file additional or supplemental applications or petitions in respect thereto, until the court eventually is satisfied that the allegations of the certificate or applications are true, and that the improvement is constructed in substantial accordance with the ordinance.
     If before the entry of such an order upon such a certificate there has been issued to the contractor in the progress of any such work, bonds to apply upon the contract price thereof, that contractor or the then owner or holder of those bonds, shall be entitled to receive in lieu thereof new bonds of equivalent amount, dated and issued after the entry of that order. Nothing contained in Sections 9-2-114 through 9-2-116 shall apply to any proceedings under Sections 9-2-72 and 9-2-73, or either of them, for the confirmation of new assessments, levied to pay for the cost of work already done.
