Call Meeting to Order Chair Nejedly called the meeting to order at 2:00 p.m. 3. Public Comments - No public comments. 4. Agenda Items a.* Receive update on construction projects within the Fiscal Year 2020-21 Capital Improvement Budget (CIB) Mr. Lopez announced this item was being provided in response to prior requests for an update on the progression of CIB approved projects, stating that staff plans to provide such updates on either a quarterly or semiannual basis moving forward. He continued with a detailed explanation of the presentation included with the agenda materials. The summary below represents notable highlights from the discussion. Outfall Improvements - Phase 7 - Mr. Lopez shared there are 1,500 joints within the Outfall pipe; 800-900 of those joints have seals. This project has repaired approximately 300 seals, and another 250 are being installed. With the number of seals being replaced, Member Pilecki inquired whether this is an indication that something other than the standard Weco-seals needs to be sought or if it is simply due to tightening the joints. Mr. Lopez replied that some of the repairs have been due to tightening, and there has been no concern to warrant looking at other types of seals or repairs to the Outfall; no significant issues have been found with the Weco-seals themselves. Filter Plant Improvements - Phase 1A - The Notice to Proceed was issued earlier today. All permits are in place, the contractor will begin mobilizing soon, and the job is moving forward on schedule. Pump Station Upgrades - Phase 1 - This project will span over two calendar years with the focus this year to prepare for the majority of construction work next summer and await equipment delivery. Mr. Lopez discussed the different project work scope progression shown on the presentation slides and responded to various Committee questions. He noted on slide 9, with the far-left picture showing a pump being lifted for inspection, that it has been good news so far finding the pumps in good shape which will bring project savings. Member Pilecki inquired how residents have responded to the project and if there were any concerns. Mr. Lopez stated there had been no complaints received from residents, the town, or the city. He shared that November 5, 2020 Regular Board Meeting Agenda Packet- Page 129 of 150 Page 4 of 6 Engineering & Operations Committee Minutes October 13, 2020 Page 3 with the pandemic, fewer people have been encountered than with other projects. Residents that have walked by the site in Moraga have been amazed with the work. One issue encountered was a watermain leak, not attributed to this project, that did contribute to some traffic congestion during the repair and water entering this project's construction area. Mr. Lopez stated that the Central San contractor is working above and beyond to ensure the water utility repair area is compacted and level. Member Pilecki suggested that it may be worthwhile for staff to make a presentation at upcoming Moraga and/or Orinda council meetings on what to expect next. Mr. Lopez replied that staff is currently creating some form of notification/update with the Communications group; however, he opined that a good time to provide a presentation might be before the surge tank and generator work begins in Orinda. Mr. Lopez answered Committee questions related to homeless encampments near the project sites and what precautions are being taken to ensure their safety and the District's security. Overall, Mr. Lopez stated that some projects in the past had required 24/7 security patrol. With this project, that has not been necessary. Additionally, staff notified proper county departments of the project work for their information. Mr. Petit shared that a security guard escorts laboratory staff when they perform their required discharge sampling for added safety. Mr. Lopez said that the Moraga and Orinda pump stations work is within already fenced-in areas; the Flush Kleen station is the one most exposed, but the contractor took steps to secure the bypass to prevent any issues. Collection System Proiects - Mr. Lopez said he chose to group various sewer renovation/replacement projects to highlight that they are designed, and construction is managed, inhouse. Of interest: • The Danville-Phase 3 project is moving sewer laterals from easements (typically in backyards) to the street. It was determined that relocating the laterals was not only more beneficial for all parties, but it was also more cost-effective. Another cost savings has been the use of a specialized horizontal directional drill rig that the contractor purchased specifically to use on this project rather than renting the equipment (picture on top-right of slide 14). As these easements are within landscaped yards, driveways or other concrete pavement areas, the work has involved a lot of trenchless work and drilling. Outreach with residents has gone very well and the work has been successful thus far.

Mr. Mestetsky shared the attached picture of the finished self-standing creek crossing that was drilled into deep piers for long-term stability. Mr. Petit noted that the pipe crossing used to be buried. Member Pilecki stated that erosion appears to be an issue and inquired how far it is in the embankment, to which Mr. Lopez replied approximately 15 feet. Mr. Lopez asked the Committee if this presentation was in a format they would like to see in the future. Member Pilecki opined it was a good amount of information; however, he requested that staff add who the construction manager is on the treatment plant projects and, for the collection system projects, to include any significant community issues. COMMITTEE ACTION: Received the update. 5. Announcements As part of the Solids Handling Facility Improvements Project, Mr. Petit announced that staff received contractor prequalification submittals from seven general contractors and seven electrical subcontractor companies. The prequalified contractors and subcontractors will be listed in the contract bid documents and invited to submit bids. 6. Suggestions for Future Agenda Items a. Receive list of upcoming agenda items and provide suggestions for any other future agenda items COMMITTEE ACTION: Received the list. 7.
