Approve Amendment to Engineering Services Agreement for Water Filtration Plant
Clearwells Replacement Final Design / CH2M HILL Engineers, Inc. (CH2M) ($149,280)
BACKGROUND
In November 2014, CH2M completed a Preliminary Design Study for the replacement of the clearwells
at the Water Filtration Plant. The clearwells are concrete cast -in-place structures that range in age from
51 to 94 years old. In the 2007 and 2010 sanitary surveys of the City's water system, the Wisconsin
Department of Natural Resources (WDNR) identified Administrative Code deficiencies with these
structures. The most recent inspection of these structures indicate they are in fair condition, at best, and
are in need of replacement based on their age and the WDNR-identified code deficiencies. The two (2)
options identified in the study were: to replace the basins in ground, which would require a sophisticated
secondary containment system due to the basins being partially below groundwater level; or construct
aboveground basins with secondary pumping to meet the WDNR's groundwater separation
requirements. The aboveground option with intermediate pumping was selected as the option that best
met the regulatory requirements and provided the simplest long-term operating requirements for the
facility. An electrical system study was done, in addition to the original Preliminary Design Study, to
identify any additional electrical system work that would need to be done to support the intermediate
pumping and the backup generators, which have issues related to their age and availability of parts and
service. In January 2017, CH2M was chosen to provide the final design services and prepare bidding
plans and specifications for the clearwell replacement project.
ANALYSIS
During the final design, utility staff and CH2M identified a number of opportunities to enhance the
project design that would provide long-term value to the Water Utility, provide better protection of
utility assets, and assure regulatory compliance during construction. These additional out -of -scope work
items include:
• Addition of a water surge protection system to reduce water hammer, which can lead to water
main breaks and equipment damage.
• Re -use of some existing assets to control construction costs while meeting project objectives.

CA #1 Memo 12-7-17.docx
• Improve storm water management on the Water Filtration Plant property and reduce the impact
on the adjacent Storm Water Utility -owned storm water system.
• Minimize construction -related disruption by integrating other City capital improvement projects,
such as the chemical room roof replacement project and standby generator replacement project,
with this project.
• Provide additional public information and community engagement opportunities for the project.
• Develop a detailed interim operations plan to maintain Water Filtration Plant reliability during
construction.
FISCAL IMPACT
This cost of this proposed contract amendment is for $149,280. Funding is available within the 2017
Capital Improvement Program from the water main construction projects coming in under budget.
RECOMMENDATIONS
Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a specialized
nature, including engineering services, may be procured without the use of formal, sealed quotes. I have
reviewed this amendment and, in accordance with Section 12-16 of the Code, I am hereby recommending
the Common Council approve this amendment.
Approved,
Mark A. Rohloff
City Manager

SCOPE OF SERVICES
Water Filtration Plant Clearwells Replacement Final Design Services
City of Oshkosh Resolution No. 17-27, Amendment No.1
During the Water Filtration Plant (WFP) Clearwells Replacement Project (Project) final design
development, the City of Oshkosh (City) made design -related decisions that provide critical benefits to
the City but that also resulted in additional engineering services. These benefits include the following:
• Safeguarding and enhancing WFP operational reliability during Project construction
• Mitigating watermain breaks and equipment damage from water hammer with a surge protection
system
• Maximizing re -use of existing assets to control costs while meeting Project objectives
• Improving storm water management on the WFP property and for the contiguous storm water
collection system
• Minimizing construction -related disruption by integrating other City capital improvement projects
with the Clearwells Replacement Project
• Providing public information and community engagement opportunities on the Project
The scope of services describes the engineering services beyond CH2M's agreement with the City: Water
Filtration Plant Clearwells Replacement Final Design Services Project City Resolution No. 17-27 dated
