Call Meeting to Order Chair Causey called the meeting to order at 9:04 a.m. 2. Public Comments November 15, 2018 Regular Board Meeting Agenda Packet- Page 180 of 254 Page 3 of 70 Engineering & Operations Committee Minutes November 5, 2018 Page 2 No public comments. Chair Causey announced that Mr. Petit had requested that Item 5 be heard out of order as the first item of business. 3. Items for Committee Recommendation to Board Agenda items proceeded immediately after Item 5 concluded. a. Review draft Position Paper to award a construction contract in the amount of$668,600 to Con J Franke Electric, Inc., the lowest responsive bidder for the Plant Control System Input and Output (1/O) Replacement Project— Phase 1, Filter Plant, District Project 7339; consider exemption from the California Environmental Quality Act (CEQA); and authorize up to a 15-percent contingency Member McGill noted that the Position Papers in the agenda packet included more alternatives and justification for discussion, as staff was requested to do, and that he appreciated this effort. Chair Causey added that since many projects seemingly sit idle from the Board's perspective until they come up for award, it would be helpful for the Board to have some background information to reflect upon when considering the projects. Mr. Petit indicated that one suggestion would be to attach an executive summary providing a detailed background summary for certain projects. Member Causey stated that it is confusing when so many projects are combined, making it difficult for the Board to oversee whether the projects are on budget and track the sources of funds. He stated it would be more helpful to collapse the different budgets into one. Staff will evaluate improvements in combining future projects, especially when bundling multiple construction projects into one, for economy of scale. Senior Engineer Nate Morales reviewed the presentation included with the agenda material. In response to a question from Member McGill, Mr. Morales said the manufacturer stopped supporting the hardware and software for the outdated programmable logic controllers (PLC) approximately five years ago. He said the PLCs are critical; therefore, as replacements are made, the 1/0 cards that are still in working order will be saved as backup inventory to use as spare parts, since not all 1/0 cards are being replaced as part of this project. Mr. Morales stated that as-builts (record drawings) have been a major challenge, and it has only gotten worse with upgrades. Some existing November 15, 2018 Regular Board Meeting Agenda Packet- Page 181 of 254 Page 4 of 70 Engineering & Operations Committee Minutes November 5, 2018 Page 3 drawings are out of date or, sometimes, there are no drawings at all, which makes maintenance very difficult. Consequently, one of the project objectives is to create and have more accurate as-built documentation as part of the scope, following the replacement of the 1/0 and PLC with new equipment. Chair Causey and Member McGill inquired how the project is tied back to asset management and what is being done differently going forward with regard to more accurate record drawings. Mr. Morales answered that staff has been supported by the Engineering CAD (computer-aided design) team and has a vested interest from the maintenance staff to mark up changes as they are made for the CAD team to update. Mr. Petit added that the District is requiring digitized record drawings from contractors and staff is now linking these drawings to the new CMMS (computer maintenance management system). Mr. Lopez stated, for example, that ten years ago the responsibility was mainly placed on the contractor and drawings were not always received or in the desired format, or accurate. Lately, staff has been using both the contractors and consultants to prepare accurate drawings and staff is ensuring the information is received. Chair Causey suggested that if changes are coming from staff and not the contractor that a procedure to ensure that information is getting updated should be in place. Mr. Morales stated that staff is now diligently updating drawings when changes are implemented. Mr. Morales continued the presentation, noting that this is a pilot project and the first wholesale change of PLC equipment. Therefore, staff is making a point to ensure it is establishing a sound design to carry out for the other systems. Mr. Morales provided the Committee with an example of an actual PLC and 1/0 cards for context. The new system will have a redundant power supply; the current system has no redundancy. Mr. Petit stated that the project received great bid results. Mr. Lopez added that the top three contractors are familiar with Central San and are currently on site with other projects. Member McGill asked why there were so many bidders compared to other projects. Mr. Lopez opined that it could be due to the time of year, staff outreach, and being provided a detailed set of plans. Mr. Morales added that since the scope of work is primarily electrical, electrical contractors were able to bid as a prime contractor. Chair Causey inquired about the $170,000 pre-purchase of PLC equipment that was done last December. Mr. Morales replied that pre- purchase was for equipment necessary for this project (which consists of approximately 10% of the total 1/0 cards being replaced). Chair Causey November 15, 2018 Regular Board Meeting Agenda Packet- Page 182 of 254 Page 5 of 70 Engineering & Operations Committee Minutes November 5, 2018 Page 4 then asked if the next phase will cost 10 times the amount of this project. Mr. Morales answered that it would be less. Mr. Lopez clarified that this project was not intended to replace all the cards, only to capture the outliers. It is estimated that$10 million would be needed to replace the rest of the outdated equipment. That future cost is captured in the current Ten-Year Capital Improvement Plan as part of large projects (i.e. facility improvements to the Solids Handling, Filter Plant, Influent Pump Station, etc.). Member McGill asked if the new cards are compatible with those that remain; Mr. Morales stated they are compatible with the addition of a special card and software. Mr. Lopez provided an overview of the financial aspects of the project, the additive bid items, the request for 15% contingency, and clarified an inquiry on a preconstruction estimate line item. Member McGill recommended approval, Chair Causey concurred. COMMITTEE ACTION: Recommended Board approval. b.* Review draft Position Paper to award a construction contract in the amount of$10,064,000 to C. Overaa & Company, the lowest responsive bidder for the Mechanical and Concrete Renovations, District Project 7351; consider exemption from the California Environmental Quality Act (CEQA); authorize up to a 10-percent contingency; and authorize the General Manager to amend an existing agreement with Carollo Engineers, Inc. to increase the original $850,000 cost ceiling by $725,000 for construction support services Senior Engineer Craig Mizutani reviewed an updated presentation (attached). Mr. Petit introduced Sanjay Reddy from Carollo Engineers (Carollo), project consultant, and Mr. Lopez introduced Associate Engineer Amanda Schmidt, project manager for the V.w Housen and Associates contract, under which the Concord Main Metering Station portion was designed. Mr. Petit stated the Concord Main Metering Station was designed under a separate project, but it was brought into this project's construction effort. The metering station scope was bid as an alternative bid item, as it needs to be agreed upon with the City of Concord and the cost must be tracked separately. The metering station bid was $404,000 but will include other November 15, 2018 Regular Board Meeting Agenda Packet- Page 183 of 254 Page 6 of 70 Engineering & Operations Committee Minutes November 5, 2018 Page 5 project costs, such as construction management, and will then be split 50% with the City. The cost split will be approximately$305,000 each. Chair Causey inquired what the project number was for the metering station task. Mr. Lopez replied it is currently under the Pump Station Upgrades Project, but Mr. Petit indicated that staff will create a separate project number to track costs. Mr. Petit advised that part of the Outfall Improvements Project-Phase 7 (Outfall Project) will be included with this project. The rest of the Outfall Project cannot be completed this fiscal year due to construction sequencing and the need for some structure renovation by this project before the flow can be diverted from the Outfall pipe. He said the budget to complete the Outfall Project will require reallocations next year. As part of the careful review process during the annual budget cycle, Mr. Petit noted that some projects may be accelerated, while others may be delayed. Those decisions are balanced judgment calls based on the engineers'professional opinions as the projects progress. Member McGill noted that delays do not necessarily result in higher costs, as illustrated by the 1/0 project just presented. Mr. Lopez added that, for cost effectiveness, Carollo's contract was used to also evaluate a few of the other treatment plant projects while Carollo was already on site, thus providing staff with valuable and timely information for refurbishments needed without having to administer another RFP process. This was done for the Odor Control equipment that is failing and for the Pre-Aeration Tanks used to remove the grit. Mr. Lopez continued the presentation, mentioning the constraints in doing work on the Outfall Project due to the influent structure gate. He responded to various questions from the Committee regarding the remaining elements of the Outfall Project, namely timing, scope of work, corrosion assumptions, and the conditions to use the alternate discharge location to Walnut Creek, as defined in the NPDES (National Pollutant Discharge Elimination System) permit. Mr. Lopez further advised that two elements were not included in this project— the grit system and Structure D. The grit system will be a future project and Structure D will be completed during the Outfall phase project. Mr. Petit also said that staff used this opportunity to inspect during the assessment, but always intended the grit system to be a separate project. Chair Causey asked what the consolidated budget meant (a staff recommendation included in the revised presentation). Mr. Lopez replied November 15, 2018 Regular Board Meeting Agenda Packet- Page 184 of 254 Page 7 of 70 Engineering & Operations Committee Minutes November 5, 2018 Page 6 the budgets shown would be combined to track as one project, as staff has been requested to do in prior meetings. A spirited discussion of budget allocation and reconciliation followed, after which the Committee recommended the project for Board for approval. COMMITTEE ACTION: Recommended Board approval. C.* Review draft Position Paper to authorize the General Manager to execute a professional engineering services agreement in an amount not to exceed $844,000 with Brown and Caldwell for design of the Influent Pump Electrical Improvements, District Project 7328 Mr. Petit introduced Lloyd Slezak from Brown and Caldwell and then proceeded with an overview of the scope and an updated project presentation (attached). In response to a questionnaire staff received via email from Chair Causey, to which staff responded prior to the meeting, attention was drawn to a new "Needs vs. Wants"slide, which Mr. Petit stated can be subjective. Tasks and their drivers were listed, with columns selecting need or want, and, lastly, the risks associated with not doing the task. Overall, the six tasks listed were all deemed needed, with two tasks (5 and 6) having dual- selection, with the want being to create a plant of the future. Mr. Petit concluded that he would like Brown and Caldwell to add alternatives with costs that can be brought back to the Board. Member McGill stated he was impressed with what staff has done with the furnaces, looking at what could be done to gain additional equipment life, and requested that staff continue to do the same with other items, such as this project, and supported the inclusion of the two alternatives. Member McGill recommended approval, Chair Causey concurred. COMMITTEE ACTION: Recommended Board approval. 4. Other Items a. Receive update on Headworks Screening Upgrade, District Project 7327 Mr. Lopez introduced Associate Engineer Chathura Abeyrathna who provided an update on the washer/compactor issue encountered in the Headworks project previously reported to the Committee. November 15, 2018 Regular Board Meeting Agenda Packet- Page 185 of 254 Page 8 of 70 Engineering & Operations Committee Minutes November 5, 2018 Page 7 Mr. Abeyrathna provided a brief overview of the Headworks screening and handling system addressed with the project. He added that since the presentation was created, the schedule has improved. The new improved washer/compactor equipment was delivered, and it is anticipated the new unit will be installed and operating this week. Mr. Petit noted that the District refused to accept the product without improvements made and that Vulcan, the manufacturer, is paying for all the modifications. The Committee had no questions. COMMITTEE ACTION: Received the update. b. Receive Capital Projects Division Quarterly Report (July to September) on capital projects, active consultant contracts, change order log, and schedule of bids and awards Mr. Lopez advised that the report was a typical quarterly update, noting that contract dates were added to the as-needed contracts report as previously requested. COMMITTEE ACTION: Received the update. C. Receive list of future agenda items There was a request to receive Committee packets earlier and a discussion about the scheduling of next year's Committee meetings. COMMITTEE ACTION: Reviewed and provided input to staff. 5.* Announcements The following item was heard out of order immediately after Public Comments. a. Mr. Petit announced that before the other agenda items were heard, he wanted to provide an overview of the Good Management Practices portion of his presentation given at an ACEC (American Council of Engineering Companies) Conference in Napa last month (attached). The overview included a refresher on reasoning for the creation a Comprehensive Wastewater Master Plan (CLAMP) (e.g. confirm future projects, estimate project cost, timing and clarity, scheduling, conducting assessments, and CWMP drivers). November 15, 2018 Regular Board Meeting Agenda Packet- Page 186 of 254 Page 9 of 70 Engineering & Operations Committee Minutes November 5, 2018 Page 8 Mr. Petit drew the Committee's attention to Central San's CLAMP and the projects that are currently in design as part of the plan, adding that some projects have been completed, and others are in various stages of design or construction. Sometimes these CLAMP projects have been bundled together for cost effectiveness. He concluded his announcement by presenting a table from the CLAMP Technical Executive Summary' listing the various treatment plant capital projects and their drivers, including those projects recommended for award on this agenda. 6. Future Scheduled Meetings a. Monday, December 10, 2018 at 9:00 a.m. 7. Suggestions for Future Agenda Items a. In response to the announcement presentation by Mr. Petit, Member McGill suggested that staff provide an update on the Treatment Plant Projects and Drivers listed in the CLAMP Technical Executive Summary and Ten-Year Capital Improvement Plan for discussion. 8.
