To track the individual design and construction contracts, staff recommends the interim water improvements be separated into three new Capital Improvement Program projects as follows: • Turnout 4 Replacement and Booster Station and Stoneridge Drive 24-Inch Potable Water Main (F-1 Line), CIP No. 24171 Recommended to be funded from the transfer of $180,426 and $551 ,061 from the Annual Water Distribution System Improvements, CIP No. 23183 and 24183, respectively. A professional services agreement with Woodard & Curran for $666,365 (see Attachment 3) and the design contingency of $65,122 will be billed toward CIP No. 24171 . • Bernal Avenue 18-Inch Potable Water Main (F-4 Line), CIP No. 24172 Recommended to be funded from the transfer of $133,000 from the Annual Water Distribution System Improvements, CIP No. 24183. A professional services agreement with Pakpour Consulting Group, Inc. for $121 ,216 (see Attachment 4) and the design contingency of$11 ,784 will be billed toward CIP No. 24172. • Sunol Boulevard 20-Inch Potable Water Main (F-7 Line), CIP No. 24173 Recommended to be funded from the transfer of $255,000 from the Annual Water Distribution System Improvements, CIP No. 24183. A professional services agreement with Mark Thomas & Company, Inc. for $231,906 (see Attachment 5) and the design contingency of$23,094 will be billed toward CIP No. 24173. To expedite the work, the on-call consultants have started preliminary design work under task authorizations as part of existing on-call contracts with the City. Additional task authorizations are issued as designers identify critical tasks that need to move forward. The task authorizations will be merged with the new contracts to ensure the proposed contract totals are not exceeded. A construction funding strategy will be developed after completing the 35 percent design estimates. Once the full scope of the project is defined and construction costs are better understood, the projects will be brought to the City Council for review, although it is anticipated that total construction costs are likely to exceed the project expenses of $6 million that were included in the proposed water rate increases presented to the City Council on July 18, 2023. The City recently received various grant funding to address PFAS and is working with the various grant sponsors to confirm that the grant funding can be used toward the interim water improvements. Schedule The design of the water line improvements is anticipated to be completed by the end of 2023, with some of the projects going to bid before the end of the year. Construction of the water lines is anticipated to start in February/March 2024 with the goal of having them in service by the peak demands of summer 2024 but timing is highly dependent on the availability of materials. The booster pump is anticipated to be completed by the end of 2024. The award of the pre-purchase of the booster station and possible purchase of identified long lead items will be presented to the City Council this fall. Page 9 of 10
