This is Addendum One to an Invitation to Bid (RFB-243-24) issued by the Commonwealth of Kentucky Department for Facilities and Support Services, Division of Engineering and Contract Administration, for the Department for Juvenile Justice. The project involves chiller replacement at the Northern Youth Development Center located at 15600 Turner Road in Crittenden, Kentucky (Kenton County). The original bid date has been moved to September 13, 2024 at 1:30 P.M. Eastern Time. Bidders must conform to the changes outlined in this addendum, which become binding upon the contract to be issued. Additional specifications and drawings will be distributed by Lynn Imaging and must be incorporated into all bids submitted.
