Authorize the City Manager and Clerk of the Council to amend the design services agreement
with Psomas, Inc., to expand the current scope of work for engineering design to include
additional design services, construction support, and project closure services in the amount of
$150,000 for an additional one -year period through September 1, 2018 so that the total sum to

DISCUSSION
The Walnut Pump Station was first constructed in the early 1960's. The pump station receives
water from several sources including three wells, and one connection with the Metropolitan Water
District (MWD). In addition, a six million gallon reservoir resides at this site providing emergency
and peak demand water supply. This facility is the main component to distribute water to the
central and downtown areas, and is therefore considered critical to the City's water distribution
system.
On September 16, 2014, the Public Works Agency entered into an agreement with Psomas, Inc.
for engineering design services to renovate and modernize the Walnut Pump Station. The
design was completed by Psomas, Inc. as scheduled.
On September 20, 2016, the project construction phase was awarded to Arnaz Engineering
Contractors. During the initial part of the construction phase, several related mechanical and
electrical equipment appurtenances were found in a state of decay and must be replaced. This
could only have been discovered when the pump station was taken off line and disassembled.
Equipment includes booster pumps, well head piping systems, electrical motors, components,

and peripherals that were not included in the original scope of work. Therefore, additional design
and construction support services are needed.
Psomas, Inc is the designer of record and is familiar with the needs of the project and the
proposed services. The recommended services will allow for the completion of the project in a
timely manner and without delays. The added scope of work and cost breakdown has been
analyzed by staff, and it provides effective value to the City and the project.
STRATEGIC PLAN ALIGNMENT
Approval of this item allows the City to meet Goal #6 - Community Facilities & Infrastructure,
Objective #1 (establish and maintain a Community Investment Plan for all City assets), Strategy
C (invest resources and technology to extend the service life of existing infrastructure to protect
the City's investment and support a high quality of life standard).
ENVIRONMENTAL IMPACT
There is no environmental impact associated with this action.
FISCAL IMPACT
Funds for the additional scope of work in the amount of $150,000 are available in the Water
Utility Capital Fund (Account No. 06617647 66301, Project 11 -6412) for expenditure FY 2017 -18
and FY 2018 -19.

SUBJECT: Proposal for Professional Engineering Design Services
Walnut Pump Station Upgrade Project
Additional Bidding and Construction Pbase Services
Dear Armando:
Pursuant to your request, we are submitting this proposal to provide additional services during the
bidding and construction phase for the Walnut Pump Station Upgrade Project.
SCOPE OF SERVICES
This proposal for additional engineering services includes the following scope of work:
1. Additional Bid Phase Assistance - Provide additional assistance during the bidding phase of
the project. This work included responding to numerous questions from bidders during hid
period that was extended several weeks beyond the original bid due date,
2. Plan Revisions for Pump and Discharge Header Replacement — At City's request, Psomas
prepared revisions to plans to include replacement of all P mtp$, motors, valves, fittings and
above ground pilling. Work included preparation of a new construction plan sheet,
coordination with City staff and pump manufacturers to determine equipment requirements.
3. Asbestos Abatement Monitoring — At City's request, Psomas retained A -Tech Consulting to
provide asbestos abatement monitoring during Contractor's demolition of the existing pump
station structure.
4. Building Permitting- Assistance — Psotnas assisted City Water staff with preparation of a
building permit application with City of Santa Ana.
S. Revisions to Structural and HVAC Plans — At City's request, Psomas will review proposed
modifications to the Sodium HypoeltloritelPOL building to remove interior wall to create a
single room. Work included revisions to structural and HVAC plans and
associated calculations.
6. Revisions to-Electrical and Instrumentation — The City requested a Hutton Centre curve

to the electrical and instrumentation plans. Two of the panels are associated with the
Chlorination System. The City also requested integration of the Chlorination System into the
current design plans. Psomas will provide updated background drawings that show the
Chlorinator skid and provide a control description for the Chlorination System. The
Chlorination System submittal has a Chlorinator PLC Pallet. It also has a control
description. However, control description and Chlorinator PLC Panel 10 list are not
consistent with the 10 associated with the Chlorinator Remote 10 Panel. Since most of the
I0 for the Chlorinator Remote 10 Panel comes from the Chlorinator skid, we recommend
that the chlorine system supplier integrate the Chlorinator Remote 10 Panel into the
Chlorinator PLC Panel.
The other new panels are called the Well 29 PLC and the SA -2 PLC, In the original design,
these panels were to be supplied by the City under separate contract. Psomas will provide
background drawings for Well 29 and SA -2.
The City has also requested revision to the hardware requirements for the Walnut Pump
Station PLC, as well as modifying the control diagrams for the Main Control Panel.
Additional Assistance with Review of Shop Drawing Submittals and RFPs — Provide
additional assistance in review of contractor shop drawing submittals and responding to
contractor RFI's.
8, Vault for Chlorination [nieotianQyill — Revise construction plans to add a precast concrete
vault for a chlorination injection quill on the existing 24 -inoh well discharge line. Plans will
show demolition of existing vault and include plan and section views of new vault and piping
modifications.
9. Optional Services — Provide engineering sevices for optional tasks as requested by the City.
Optional services will be provided only upon prior authorization of the City.
We propose to provide engineering services to complete the work as discussed above on an hourly
basis with the total fee not to exceed $132,311 as summarized in the attached fee table.
If you have any questions, please do not hesitate to contact us.
Sincerely,
PSO MAS
