Senate Bill 428 proposes amendments to the current law regarding county public works notice and competitive bidding thresholds. The bill seeks to increase the notice threshold from $5,000 to $10,000 and the bidding threshold from $25,000 to $50,000, with adjustments for inflation every five years. Additionally, it introduces exceptions to the bidding requirements for public works aimed at providing housing for individuals on supervised release and for improvements constructed by private individuals and donated to the county.

The bill also renumbers and amends existing statutes to reflect these changes, specifying that contracts exceeding the new bidding threshold must be awarded to the lowest responsible bidder, while those below the notice threshold can be let as directed by the county board. Furthermore, it clarifies that the new provisions do not apply to certain donated projects or volunteer labor. The effective date of these changes will be determined, and the thresholds will be adjusted based on the U.S. consumer price index every five years.
