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, 25G -1 Amendment Agreement with Psomas, Inc. For Engineering Design, Construction Support and Project Closure Services May 2, 2017 Page 2 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.

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.

CA 92707 Te1714.751,7373 Fax 714.545.8889 Ww ,Pconnas.com 25G -5 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.
