1. BACKGROUND
This ordinance authorizes the Director of Columbus Water and Power to enter into a planned contract modification for professional engineering services with Arcadis U.S. Inc. for the JPWTP Power Systems Upgrade and Safety Improvements project, CIP #650257-100101, in an amount up to $1,528,349.37.
