Where an improvement has been constructed with the aid of any agency of the Federal government, or other governmental agency, the provisions of Sections 9-2-114 through 9-2-116 shall not apply except as to the manner of the final hearing. In that case, upon completion of the project the board of local improvements shall adopt a resolution accepting the project as constructed in full conformance with the ordinance and specifications therefor and approving the cost of the work upon its completion as being in compliance with the ordinance and specifications. Whereupon a certified copy of this resolution shall be filed in the court in which the judgment of confirmation was entered and a hearing had upon the cost and completion in the same manner as is provided in Sections 9-2-114 through 9-2-116.
