In any case where an improvement is to be constructed with the aid and assistance of any agency of the Federal Government, or any other governmental agency, the provisions of Sections 9-2-100 through 9-2-112 shall not apply where they conflict with this section. The board of local improvements in cities having a population of 500,000 or more and the corporate authorities in municipalities having a population of less than 500,000 may proceed at any time within 90 days after the judgment of confirmation has been entered in the construction of the work. Within 90 days after the judgment of confirmation the board of local improvements in cities having a population of 500,000 or more and the corporate authorities in municipalities having a population of less than 500,000, shall adopt a resolution determining to proceed with the construction of the work, publish the resolution within 10 days in one or more newspapers published in the municipality, or, if no newspaper is published therein, then in one or more newspapers with a general circulation within the municipality. In municipalities with less than 500 population in which no newspaper is published, publication may instead be made by posting a notice in 3 prominent places within the municipality.
Ten days after the publishing of this resolution a copy thereof, properly certified, shall be filed in the court in which the judgment of confirmation was entered. This resolution shall be authority for the issuing of the warrant to the collector for the collection of the assessment. Each assessment shall draw interest from the date of passage of the resolution of intention to proceed with the work, as provided in Sections 9-2-48 through 9-2-51.
After this resolution has been filed and a warrant issued to the collector for the collection of the assessment, the municipality may issue bonds or vouchers to anticipate the collection of the unpaid portions of all installments of the assessment, including the first installment if it has not been certified delinquent, for the purpose of applying the proceeds of the bonds toward paying the cost of the improvement, including all expenses of making, levying, collecting the assessment and engineering and attorneys' fees. These bonds if issued shall be sold for not less than par and accrued interest and the proceeds used for that purpose, or the bonds may be issued, for not less than par and accrued interest, in payment for materials, labor, or services.
No person furnishing materials or supplying labor for the construction of any such local improvement shall have any claim or lien against the municipality except from the collection of the special assessments or special taxes made or to be made for that work, or from the proceeds of the sale of bonds to anticipate the collection of the same in case such bonds have been sold.
