HomeMy WebLinkAbout09.c EDB JE Sewer Model Conversion 2.0 EXECUTIVE SUMMARY
AGENDA ITEM:
Proposed Supplemental Agreement No. 1 to the Civil and Environmental Engineering Professional Services
Agreement RFQ 2023/2024-A01 with Jones Edmunds and Associates, Inc., (JE) to provide Professional
Engineering Services for the Conversion and Development of CCUA's Hydraulic Sewer Model.
Project Number: 2023-065
Engineering Operating Budget Number: 101.511.563.311
Date: November 15, 2024
BACKGROUND:
Staff requests the Board of Supervisors approve Supplemental Agreement No. 1 with JE to provide hydraulic
model conversion and development services for CCUA. Staff considers the hydraulic model a valuable tool used
regularly for system analysis and planning. CCUA staff included funding in the current fiscal year for model
conversion and development.
In the first phase of this project, under a previous agreement, JE analyzed CCUA's existing model and provided
a summary and recommendation of the modeling alternatives available because the current modeling software is
being discontinued. CCUA elected to convert the existing model to Innovyze's InfoWorks ICM modeling
software and JE completed the conversion and truthing of the Mid-Clay WRF service area model. This
supplemental agreement represents a continuation of that work. JE will convert the existing model of CCUA's
Spencer's Crossing WRF service area to the new software, update the model to include all current elements, and
develop a future scenario for planning. JE proposed to provide these services for a time and materials fee not to
exceed $54,480.00.
BUDGET:
Staff budgeted $100,000 in the Fiscal Year 24/25 Operating Budget for model conversion and updating.
CCNA:
CCNA, F.S. s. 287.055, does apply to the use of a consultant under continuing contract. The anticipated cost of
the study does not exceed $500,000.00. Staff negotiated the Supplemental Agreement in compliance with F.S. s.
287.055. Staff and the consultant negotiated the scope and fee for the professional services at a compensation
which CCUA determines is fair, competitive, and reasonable.
RECOMMENDATION:
Staff respectfully recommends that the Board of Supervisors approve the attached Supplemental Agreement No.
1 with JE for consulting services to provide hydraulic model conversion and development services for CCUA.

RE: Sewer Model Updates
Draft Scope of Services and Fee Schedule
Jones Edmunds Opportunity No.: 95696-171-24
Dear Mr. Steinbrecher:
Clay County Utility Authority (CCUA) currently has portions of its wastewater collection and
transmission system model in the InfoSewer modeling platform. InfoSewer will not be
supported in the future, so CCUA is migrating to ICM InfoWorks. The Mid-Clay model was
the first service area migrated to the new platform. The Spencer's Crossing water
reclamation facility (WRF) collection and transmission system (Spencer's Crossing) is the
next service area that CCUA wants to convert to ICM InfoWorks.
The updated model will contain both an existing conditions and an agreed-on future
conditions (e.g., 20-year or buildout) scenarios. Jones Edmunds will review the scenario
results and compare them to CCUA's level-of-service (LOS) criteria to determine where
alternatives may need to be evaluated in the future. The scope of services below outlines
the steps that are required to meet the goals above.
SCOPE OF SERVICES
Jones Edmunds will provide the following services:
• Review and convert the Spencer's Crossing InfoSewer model into ICM InfoWorks,
■ Evaluate existing conditions and one set of future conditions, comparing results to
CCUA's LOS in the Draft Design Guide (January 2018).
TASK 1 - MODEL REVIEW, CONVERSION, AND DEVELOPMENT
Purpose: Convert the Spencer's Crossing InfoSewer model to ICM InfoWorks.
Jones Edmunds will convert the existing Spenser's Crossing InfoSewer model into ICM
InfoWorks. We anticipate including the full gravity system in the model.
Two flow conditions will be modeled: dry weather and wet weather (i.e., design conditions).
Dry weather conditions will be used to evaluate operational issues (e.g., odor control
concerns from long pump-off conditions and non-scouring velocities). Dry weather flows will

be distributed based on monthly water meter data. Total flow and the diurnal distribution
will be based on flow measured at the Spenser's Crossing WRF.
Based on the experience with the Mid-Clay model conversion, we will emphasize pump
curve updates that will include more robust pump curves as well as cross-checks to the
latest known pump/impeller combinations for each pump station.
Wet weather conditions will be used to evaluate system capacity (e.g., overflows, high
alarms, high velocities, and high pressures). Wet weather flows will be based on measured
peak flows at the Spenser's Crossing WRF to determine a multiplier of the diurnal curve.
We will evaluate the model results using the LOS criteria in the Draft Design Guide. We will
document the model review, conversion, and development in a TM and review the TM with
CCUA.
Deliverables: TM of model review, conversion, and development; and a copy of the
model.
TASK 2 - FUTURE CONDITIONS MODEL
Purpose: Evaluate Spenser's Crossing under future conditions.
Jones Edmunds will develop flows for a future conditions scenario agreed to by CCUA. We
will run the future conditions model for wet weather only. We will summarize the future
conditions flows and present our evaluation of the model results using the LOS criteria in
the Draft Design Guide in a TM and review the TM with CCUA.
Deliverable: TM of future conditions and a copy of the model.
SCHEDULE AND COMPENSATION
Jones Edmunds proposes to complete this scope of services for a time-and-materials fee not
to exceed $54,480.00 and complete this assignment by February 28, 2025, assuming a
Notice to Proceed in November 2024.
PROPOSAL CLARIFICATIONS/EXCLUSIONS
■ Field data collection is excluded.
■ CCUA will provide review comments within 2 weeks of receiving review material.
