Public Comments None. July 19, 2018 Regular Board Meeting Agenda Packet- Page 98 of 111 Page 3 of 11 Engineering & Operations Committee Minutes July 9, 2018 Page 2 3. Items for Committee Recommendation to Board a. Review draft Position Paper to authorize the General Manager to execute professional engineering services agreements with JDH Corrosion Consultants, Inc. and Alisto Engineering Group in an amount not to exceed $150,000 each to provide On-Call Corrosion Engineering Services for District Projects Mr. Lopez provided an overview of the request to contract with two firms for as-needed corrosion engineering services. Staff has experience with JDH Corrosion Consultants, Inc. and has reviewed Alisto Engineering Group's work experience with other utility and public agencies. These firms will provide on-call corrosion specialty services for several capital related projects. Member McGill inquired whether the entire $300,000 is expected to be utilized and how it will be managed. Mr. Lopez responded that most tasks are typically small (e.g. $5,000 per task) and that the contracts would be monitored and balanced between the two consultants. Chair Causey asked whether these services replace the force-main evaluation to which Mr. Lopez replied no; that evaluation will be performed under a separate program. Mr. Lopez answered questions pertaining to cathodic protection and assessments and confirmed that the proposed contracts would be for $50,000 per year/per contract, for a total of$150,000 per consultant for a combined three-year period. Member McGill recommended approval and Chair Causey concurred. COMMITTEE ACTION: Reviewed and recommended Board approval. 4. Other Items a. Receive an update on the Server Room Relocation, District Project 8243 and Plant Operations Building Seismic Upgrades, District Project 7362 Mr. Lopez introduced Mr. Hodges as the presenter for these project updates and announced Mr. Hodges'recent promotion to Senior Engineer. Mr. Hodges reviewed the presentation provided in the agenda materials, summarizing the scope of work, project improvements, relocation plans, and the associated impacts. Member McGill inquired about inclusion of the Multi-Purpose Room (MPR) in the seismic upgrades as he thought the MPR was already a seismically July 19, 2018 Regular Board Meeting Agenda Packet- Page 99 of 111 Page 4 of 11 Engineering & Operations Committee Minutes July 9, 2018 Page 3 constructed room. Mr. Petit replied that the MPR has not been seismically retrofitted and that the Board was informed of the project at the design stage. Mr. Bailey added staff was providing this update in part to inform the Board that the MPR will be unavailable during the construction phase, and that the project may potentially impact use of the Board Room briefly. Staff intends to include an announcement in the July 19, 2018 Board packet advising of the upcoming construction bid period advertisement. Chair Causey inquired whether the Board will be asked to approve the bid release. Mr. Lopez responded that typically the Board is provided an announcement for informational purposes; however, Mr. Bailey stated that staff could request in this case that the Board approve the advertisement. Chair Causey indicated that would be his preference. Mr. Petit, Mr. Lopez, and Mr. Hodges responded to questions pertaining to the Americans with Disabilities Act (ADA) restroom upgrades near the MPR, the addition of a publicly accessible ADA restroom at the Headquarters Office Building (HOB) lobby, and the feasibility of including the restrooms near the Board Room in this project. Member McGill inquired when the new server room was planned to be operational. Mr. Petit replied that the anticipated start-up is June 2019. Mr. Hodges added that he does not anticipate the construction activities to impact any of the scheduled Board meetings. Mr. Bailey added that timing of the next Central San Academy will need to be taken into consideration. Chair Causey recommended considering moving the academy to a more centralized location within the District which may be more beneficial for participants. The use of the Collection System Operations (CSO) facility located in Walnut Creek was suggested as an option. Mr. Lopez advised that the cost estimate on Slide 11 did not include the security improvement/vulnerability budget, which is approximately $750,000; therefore, the total construction cost is closer to $5 million. He answered additional questions pertaining to contingency and budget comparison. Chair Causey requested that staff include all three project numbers and updated costs when the item is brought before the Board. COMMITTEE ACTION: Requested that (1) advertisement of the construction bid documents be brought to the Board for approval (in place of a General Manager announcement), and (2) all three project numbers be included along with updated the project costs.

The project is 90-percent complete; four new bar screens have been installed, two standby screens have been rehabilitated for backup purposes, and new odor control ducts and gas detection equipment has been added. The new screens have an enclosed design connected to the odor control system which will assist with Health Risk Assessment compliance. Mr. Petit responded to questions pertaining to disposal costs associated with the screening now being collected and compacted as part of the headworks, and water method used to convey screenings in a trough and washer/compactor units. The rate of removal is very good with an average of 23 tons of materials being collected monthly. One item of note has been ongoing issues with the brush screw-mount design on the new compactors. The brush attachments to the augers are weak and appear to not hold with the backpressure weight of the tilting trough. The issue has already occurred nine separate times; therefore, the contractor, consultant, and manufacturer have been put on notice to resolve the equipment failure issue. Staff has brought this matter to the attention of the District's legal counsel. Overall, the project has been successful. Operations has experienced less plugging downstream and reduced cleaning of the ultraviolet lamps at the end stages. COMMITTEE ACTION: Received the information. C. Receive list of future agenda items COMMITTEE ACTION: Received and provided input to staff. 5. Announcements Mr. Bailey advised that a regional water system and supply update will be jointly presented by the Dublin San Ramon Services District and Zone 7 Water Agency the evening of July 10, 2018 at the San Ramon City Council meeting. 6.
