Explanation
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 Sewer System Capacity Model (SSCM) Update 2020 project, CIP #650460-100002, in an amount up to $2,000,742.92.
The sewer collection system model developed and enhanced by the SSCM Update 2020 project is the principle tool used to manage the planning and operations of the City’s sewer collection system. Enhancement of this tool is vital to minimizing sewer overflows and backups and thereby minimizing negative impacts to the environment caused by the City’s sewer system. The continual updating of this model is also necessary to ensure compliance with the City’s consent orders with the Ohio Environmental Protection Agency.
The SSCM 2020 project enhances the City’s existing system-wide sewer collection models to support the Blueprint Columbus Program, operation & maintenance (O&M) of the collection system, operation of two Wastewater Treatment Plants, Capital Improvement Projects (CIPs), real time control initiatives (RTC) and sewer capacity evaluations. The model must be updated as new data becomes available and new development occurs and to perform model runs and analyses as directed by the City.
This contract modification is needed to add funding to continue services.
