Explanation

 

1.   BACKGROUND:  This legislation authorizes the Director of Public Utilities to modify (Mod #2) a professional engineering services agreement with ARCADIS U.S. Inc. for the Sewer System Capacity Model Update 2012  Project for the Division of Sewerage and Drainage. The initial contract covered work for the first year with four subsequent annual contract modifications planned. This modification is needed to perform model applications, monitoring and data management, refinement of the sanitary model, stormwater model, real time control and system operation, deliverables and Blueprint Columbus Integrated Plan support.

 

The sewer collection system model developed and enhanced by the Model Update 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.

 

MODIFICATION INFORMATION:

1.1                     Amount of additional funds to be expended:  $3,075,175.32

 

      Original contract:                                                                                    $4,326,563.00

Modification #1                                                                                    $5,328,048.34

Future

Modification #3                                                                                    $2,000,000.00

 

1.2. Reasons additional goods/services could not be foreseen:  

This is a multi-year agreement with planned modifications. 

 

1.3. Reason other procurement processes are not used: 

                     Uninterrupted support of the Blueprint Columbus Integrated Plan program is critical and work completed to date would have to be repeated if this project was rebid.

A Cost Summary was submitted by the Consultant and reviewed and approved by Department personnel.

 

2.                     Project Task Description:  Overall project scope elements:

                     Utilize all existing SWMM 5 models and data from the Sewer System Capacity Model Update 2006 project

                     Utilize all available City data (GIS sewer attribute data, atlas maps, other GIS features/layers, flow monitor data, rain gauge data, PARS, MSIUS, etc.)

                     Review and utilize current Inflow/Infiltration study reports and SWMM 5 models (where applicable)

                     Perform rain gauge: review, data collection/editing and rainfall analysis

                     Perform flow monitoring: review, data collection/editing and dry/wet weather flow analysis

                     Develop improved methodology for representing groundwater in the models

                     Update dry weather flow patterns and time series

                     Perform dry weather flow calibrations

                     Perform wet weather flow calibrations, and verification/validation

                     Perform field investigations

                     Enhance City GIS sewer attribute data as needed

                     Prepare and deliver various technical reports and memorandum

                     Deliver all collected flow monitor and rainfall data

                     Deliver draft and final SWMM 5 models

                     Provide training of City staff

                     Redefine 10 year, 5 year and 2 year level of service

                     Perform various model applications (to be defined in each phase)

                     Support Blueprint Columbus program

                     These tasks will be realized through completion of the Sewer System Capacity Model - Model Update 2012 through a series of five (5) phases hereinafter referred to as: Year 1, Year 2, Year 3, Year 4 and Year 5.
