1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a planned contract modification for professional engineering services with Arcadis U.S. Inc. for the JPWWTP Power Systems Upgrade and Safety Improvements project, CIP #650257-100101, in an amount up to $716,000.00.
The original contract was for preliminary design services relating to arc flash hazards and coordination issues with electrical equipment at the Jackson Pike Wastewater Treatment Plant (JPWWTP).
