Request for Execution of Professional Engineering
Contract
INTRODUCTION
The purpose of this memorandum is to request execution of the attached task order for
professional engineering services with Strand Associates of Madison, Wisconsin for the
Eagle Point Water Treatment Plant Process and Condition Assessment Project 2021 in the
amount of $187,093.
BACKGROUND
Over several decades, the City of Dubuque has experienced an increase in development, in
both the residential and commercial sectors. Such successful growth is resulting in challenges
that reach beyond the treatment, distribution, and storage system original footprints; notably,
the recent expansion of infrastructure to provide service to the subdivisions of Twin Ridge to
the south and Vernon and Barrington Lakes water systems to the west along with proposed
water main extensions to bring high quality drinking water to other areas of the community.
Having reliable and dependable water supply and infrastructure is critical to supporting all the
City's customers today and tomorrow.
As the City looks to the future outlined in the City's Comprehensive Plan and with the
completion of the SW Arterial, it is increasingly important that the existing water supply and
infrastructure is hydraulically analyzed to determine its capacity and capability to serve. As
part of the City's commitment to be ready for not only today's demands the city also supports
the development of a water supply, distribution, and storage master plan.
The master plan will serve to provide the City direction in the development of alternative and
additional water supply sources and treatment facilities, improve customer service through the
evaluation of the pressure zones serving Dubuque, evaluate the existing aging water
treatment plant and its processes, and determine a strategy for systematically
replacing/rehabilitating aging infrastructure.
The first phase of the master planning process starts with a comprehensive physical condition
assessment of its water supply, treatment process, pumping capacity, and sludge treatment
facilities.
DISCUSSION
On September 7, 2021, the City initiated a request for engineering proposals for the Eagle
Point Water Treatment Plant Process and Condition Assessment Project.
The project is the result of many staff and management discussions regarding how to
optimize the water treatment plant operation to reach a sustainable maximum output to meet
the current and future water demand. The last significant treatment plant improvement
occurred in 1979 with the addition of the north plant and the lime solids handling facility.
Unfortunately, due to issues arising during construction of the north plant the facility was not
able to achieve a discharge output of 20 million gallons per day as designed. While the facility
may or may not be able to achieve the 1979 design capacity, the ability to review and analyze
the condition and process of the existing facility allows the City an opportunity to take every
possible advantage of innovative methods, and a refreshed engineered design perspective to
see what the maximum sustained capacity of the facility could be.
The project also provides for the opportunity to evaluate protection and maintenance of the
City's source water supply; and determine other possible water supply sources along with a
second or complementary water treatment plant. A second treatment plant would offset
inefficiencies and operational challenges with the current Eagle Point Water Treatment Plant's
location, and potentially improve water distribution and pumping operations.
The request for proposal included a requirement for the engineering firm to evaluate the major
structural, mechanical, electrical, instrumentation and control systems, and processes
associated with the Eagle Point Water Treatment Plant. Each major process will be evaluated
for deficiencies and a report will be created identifying, immediate (6-12months), mid -length
(12-60months), and long term (beyond 5years) process improvements. Including but not
limited to improvements that may be necessary to current chemical feed systems and major
chemical, biological treatment processes. A final report will be provided detailing any and all
changes to increase treatment plant production and necessary side -stream piping re -work for
chemical compliance; including a list and planning level costs for said improvements required
to optimize the water treatment process and the discharge rate.
Engineering Firm Review and Short List Process
The city received two engineering proposals on September 17, 2021. Each proposal was
reviewed and scored by an approved committee. Proposals were submitted by the team of
HDR/Origin Design of Des Moines Iowa and Dubuque, Iowa and Strand Associates of
Madison, Wisconsin. The selection committee comprised of staff from the Water, Engineering,
W&RRC, and an independent consultant with experience in the water industry. The
committee reviewed each proposal to ensure that the minimum requirements of the proposal
format were met. They were tasked with reviewing each proposal using a scoring system to
place qualifying proposals on a consultant short-list for interview.
The selection committee recommended both teams be selected for interview. The interviews
were held on September 24, 2021. The interview format provided for a short presentation
from the consultant. Both, the original submitted proposal and the consultant interviews were
used to select the recommended firm for the project.
Engineering Firm Selection and Recommendation
During the interviews, the firms highlighted why their firm should be selected and clearly
1
demonstrated a keen interest in working with the City of Dubuque.
Strand Associates demonstrated a firm understanding of the project and were able to speak
in detail about each major piece of equipment and process. They were able to talk to specific
valves not in operation and how they could be re -piped or used to combine flows from the
north and south plants.
They also went into detail on sludge handling, filter backwash times, possible methods of
disinfection versus sodium hypochlorite, which is currently in use, and how the plant could be
optimized to convert to surface water treatment in the event the wells were to come under the
influence of surface water from the Mississippi River.
Strand's engineers demonstrated a strong understanding of chemistry and SCADA controls
and instrumentation systems and integrated these fields into the discussion on the overall
operations, possible automation, and how they will play a role in optimizing the current facility.
They were also familiar with optimized corrosion control and how the addition of a second
water treatment facility could be done without disrupting corrosion control. The team provided
an in-depth presentation which clearly answered the question pertaining to innovative design
and immediate recommendations they were able surmise from their plant tours including how
the city can address upcoming regulatory testing and treatment requirements pertaining to
per- and polyfluoroalkyl substances (PFAS man-made chemicals) along with discussion on
UV disinfection and reverse osmosis systems. The team is currently performing similar work
in Cedar Rapids, Iowa.
Strand's schedule will be executed over 6-months, with key activities being completed to meet
the final budget submittal deadlines for FY2023.
In reviewing the project scope and budget with Strand, a discussion was held as to the
possibility of separating the project into phases. The result from the discussion was that there
was no clear financial benefit to phasing the project and risk that a key area or process
maybe overlooked due to any delay to move part of the project out to FY2023. Therefore, the
recommendation is that the project be awarded in its entirety.
City Attorney Brumwell has reviewed and is in agreement with the form and essential terms of
the attached Strand Associates task order.
BUDGET IMPACT
Funding for the project will be from 740-2387 Water Plant Assessment Plan and as
necessary, remaining project funds available from 740-2836 Kennedy Road Water Main
Extension Project (Water Line Extensions to New Developments), which would require
reallocation of the funds to support the water treatment plant condition and process
assessment project.
