(CIP #7102754)
DATE: January 11, 2022
The City received six responses to a Request for Proposals for engineering design
services for the Twin Ridge Sanitary Sewer Extension Project. The review committee
individually reviewed the proposals and then met to discuss the RFP responses. The
consensus of the review committee was that Origin Design demonstrated the highest
level of professional competence, had a proven track record in the abandonment of
wastewater lagoons and design of wastewater collection systems, and had the best
understanding of the City's overall objectives for the project and the sanitary sewer
system.
City Engineer Gus Psihoyos requests City Council authorization to negotiate and enter
into a contract with Origin Design for an estimated fee of $66,200 to provide engineering
design services for the Twin Ridge Sanitary Sewer Extension Project.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

INTRODUCTION
The purpose of this memo is to seek authorization to negotiate and enter into a contract
with Origin Design to provide engineering design services for the Twin Ridge Sanitary
Sewer Extension Project.
BACKGROUND
Over 60 years ago the City of Dubuque started to invest in sanitary sewer infrastructure
to protect the health of its citizens and to serve the growth that had occurred and was
occurring along its western City limits. The Catfish Creek Interceptor Sewer (CCIS) was
constructed in 1956, which allowed the City to extend sanitary sewers to property
owners within the sewer shed. The Catfish Creek Pump Station (CCPS) and Water
Pollution Control Plant, now referred to as Water Recourse Recovery Center (WRRC),
were constructed in the late 1960's. Since the late 1960's, the community has grown
and expanded to the west. The City has invested in renovations and replacements at
WRRC and CCPS to meet state and federal regulations, and to adequately serve its
expanding community.
In 1998 the City began to extend sanitary sewer along Granger Creek, to the Dubuque
Technology Park. The Granger Creek Interceptor sewer extension consisted of the
Granger Creek Pump Station and approximately 17,600 LF of both 20 inch and 18"
diameter pipe.
The City purchased the privately owned Twin Ridge Subdivision sanitary sewer and
water systems in 2015. The existing sanitary sewer collection system discharges into a
two cell lagoon, which is also owned and operated by the City. The permit for the
lagoon expires in March of 2024 and with no room for expanding the lagoons, to meet
current design standards, it will be abandoned and the collection system connected to
the Granger Creek Interceptor sewer.
The City of Dubuque submitted a facility plan to Iowa Department of Natural Resources
(IDNR), in September of 2021, which identified three projects related to the Granger
Creek Interceptor Sewer System. One of the three projects is to extend sanitary sewer
to the Twin Ridge Subdivision and abandon the lagoon system. The facility plan is
based on the results of an intensive evaluation of the existing interceptor collection and
pumping systems that convey sewage to the Water Resource Recovery Center
(WRRC).
DISCUSSION
The City received six RFP responses by the December 22, 2021 deadline. The
respondents to the RFP consisted of: Origin Design (Dubuque, IA), WHKS (E.
Dubuque, IL), MSA, (Dubuque, IA), Fehr Graham (Manchester, IA), Snyder &
Associates (Cedar Rapids, IA), and Delta 3 (Dubuque, IA).
The proposal review committee (Committee) consisted of Engineering Technician Todd
Irwin, Water & Resource Recovery Center Manager William O'brien, Civil Engineer
Deron Muehring, Project Manager Steve Sampson Brown, and Water Department
Manager Christopher Lester.
Having reviewed the proposals individually, the Committee met on December 28' and
29th, 2021, to discuss and score the RFP responses. The Committee's evaluation and
subsequent scoring was based on each firm's qualifications, experience with projects of
similar scope, interest in the project, and availability. Points were awarded (0 thru 100)
based on the evaluation criteria identified in the RFP. The estimated fee component of
the submittal was not revealed to the committee prior to the initial evaluation and
scoring.
The committee's evaluation results are as follows:
Origin Design:
96.33%
WHKS
88.67%
MSA
87.33%
Fehr Graham
83.33%
Snyder & Associates
82.67%
Delta 3
66.67%
The consensus of the Committee was that Origin Design demonstrated:
• The highest level of professional competence and a proven track record in the
abandonment of wastewater lagoons and design of wastewater collection
systems.
• Thorough knowledge and understanding of the project scope.
• Experience of the team working with the City on similar projects.
• High level of interest in the project along with creativity and problem -solving
ability.
• Best understanding of the City's overall objectives, for the project, and the
sanitary sewer system.
RECOMMENDATION
The proposal review committee recommends that the City negotiate a scope of services
and enter into a contract with Origin Design for the engineering design of the Twin
Ridge Sanitary Sewer Extension Project.
BUDGETIMPACT
The engineering design fee, estimated at $66,200.00, and additional engineering
expenses will be funded by reallocating $120,000 from the Fiscal Year 2022
appropriation for the Sanitary Sewer Extensions to Existing Developments
(CIP#7101350) in the amount of $500,000.00. Revenue for the project design is from
the State Revolving Fund (SRF) loan.
ACTION TO BE TAKEN
I respectfully request the authorization to negotiate and execute a contract with Origin
Design for engineering services for the Twin Ridge Sanitary Sewer Extension Project.
