KgLLIAMS SANITARY DISTRICT President ENGINEERING & OPERATIONS MICHAEL R.MCGILL President Pro Tent COMMITTEE PAUL H. CAUSEY JAMES A. NEJEDLY TAD J. PILECKI ACTION SUMMARY PHONE: (925) 228 -9500 FAX: (925) 676 -7211 Chair Pilecki www.centralsan.org Member Causey Monday, August 25, 2014 12:00 p.m. 2 "d Floor Conference Room 5019 Imhoff Place Martinez, California PRESENT: Chair Tad Pilecki, Member Paul Causey, General Manager Roger Bailey, Director of Engineering Jean -Marc Petit, Director of Administration David Heath, Provisional Capital Projects Division Manager Edgar Lopez (arrived after Item 3), Senior Engineer Sasha Mestetsky (arrived after Item 3), Accountant Amal Lyon (arrived after Item 3), Engineering Assistant III Earlene Millier (arrived after Item 3; left after Item 5), Assistant to the Secretary of the District Donna Anderson, Senior Administrative Technician Cynthia Granzella Call Meeting to Order Chair Pilecki called the meeting to order at 12:15 p.m. 2. Public Comments None. 3. Discuss management of the Capital Improvement Budget (CIB) process, including budget tracking and reporting and possible changes to the prioritization and estimation process General Manager Roger Bailey stated that one of the Board's goals in its newly adopted Strategic Plan is to annually update the Capital Improvement Program, a Engineering & Operations Committee Action Summary August 25, 2014 Page 2 part of which includes ensuring transparency of the CIB. He said staff wished to begin a dialog to address ways to modify the format of the District's CIB so pertinent data is more readily accessible to Board Members and the public. While all relevant information is contained within the current reporting format, he acknowledged that some figures must be derived from data located elsewhere in the CIB. He asked for the Committee's input in this regard. Chair Pilecki said the current system has worked for over twenty years and he believes transparency is evident. Furthermore, once a new accounting software system is in place, as envisioned under the Information Technology (IT) Master Plan under development, it will be easier for staff to prepare more detailed reports without spending a lot of extra time. Adding more columns of data to the current reporting format, when that information is already included elsewhere, would create more work for staff, whose energy is better spent working on other issues such as input for the IT Master Plan. Member Causey said he believes the current CIB format makes it difficult to figure out what amount the Board has authorized for any given project, thus making it difficult to see if projects are running over or under budget. Director of Engineering Jean -Marc Petit noted that another area that staff is reviewing is changes to its methodology for prioritization of capital projects. Staff has developed a template that is currently being tested throughout the four capital programs (Treatment Plant, Collection System, General Improvements, and Recycled Water). Once ready, staff will bring it to the Committee for input prior to presenting it to the full Board. Chair Pilecki supported this idea, especially if it does not create additional work for staff. Mr. Bailey said he would work with staff to modify the CIB reports in such a way that staff will not be unduly burdened but the data will clearly indicate total authorized budget amounts and any prior year carryovers. He noted that these changes may also be helpful to newer staff members who work with the capital program. COMMITTEE ACTION: Discussed and provided input to staff. 4. Receive Fiscal Year (FY) 2013 -14 Capital Improvement Budget Year -End Status Report Provisional Capital Projects Division Manager Edgar Lopez reviewed the information contained in the agenda packet. Noting that certain projects may be Engineering & Operations Committee Action Summary August 25, 2014 Page 3 over the "projected" expenditure amount, but not the "authorized" budget amount, Chair Pilecki suggested the addition of one more column showing "total authorized budget" to address Member Causey's concerns. COMMITTEE ACTION: Received the report; directed staff to add another column to the report showing "total authorized budget;" and recommended the Board receive the report at the September 4, 2014 Board meeting. *5. Review closeout of Capital Improvement Projects Engineering Assistant 111 Earlene Millier reviewed her memorandum included with the agenda packet. Chair Pilecki said he would like additional information added to the Project Descriptions in Attachment 2 to her memorandum for the following projects because they expended almost the entire 15 percent contract contingency at the time the projects were awarded: District Project 7241- Wet Weather Bypass Improvements District Project 5973 - North Orinda Sewer Renovations, Phase 4 District Project 8401- Walnut Creek Sewer Renovations, Phase 9 Ms. Millier said she would add the requested information to the final version of the memorandum (see attached final memorandum). In response to a question from Member Causey about the Treatment Plant Master Plan (TPMP), Mr. Bailey said the Plant of the Future work will be encompassed within the scope of the TPMP. He said staff will provide the Committee with an update on budgeting for the TPMP and how the Treatment Plant of the Future costs will factor into the TPMP. A PowerPoint was distributed (copy attached) on Projects Completed /Closed Out in Fiscal Year 2013 -14. Mr. Lopez reviewed the portions related to the Treatment Plant, General Improvements, and Recycled Water programs; Senior Engineer Sasha Mestetsky reviewed the portion related to the Collection System program. With regard to TV inspection of sewer lines, Chair Pilecki inquired as to the status of the collection system degradation analysis. Mr. Petit said staff has been working on it and will present the results once they become available. COMMITTEE ACTION: Reviewed closeout; provided input to staff; and directed staff to augment the memorandum as indicated above. Engineering & Operations Committee Action Summary August 25, 2014 Page 4 6. Receive report regarding any projects approaching a budget overrun within the 15 percent General Manager authority, if needed Mr. Mestetsky briefly summarized issues concerning the Lafayette Sewer Renovations, Phase 8, District Project 8404. Final costs may go over the authorized project total, but within the General Manager's authority. COMMITTEE ACTION: Received the report and provided input to staff. *7. Receive Change Order Log, Quarterly Reports, and Bid Schedules to compare budgeted versus actual costs Mr. Lopez discussed newly discovered structural repairs on Primary Sedimentation Tank 3 that will be necessary as part of the Primary Treatment Renovations, District Project 7285. The cost of the repairs is anticipated to be within the General Manager's authority. Mr. Mestetsky recapped an urgent repair situation in San Ramon that was recently repaired by K. J. Woods, the contractor performing the Walnut Creek Sewer Renovations, Phase 10, District Project 8413. This work was completed on a Time and Material (T &M) basis and will result in a change order that may potentially reach $50,000. Mr. Lopez distributed Attachments 2 (Summary of Bids) and 6 (Post - Bid/Preconstruction Estimate) (copies of which are attached) to the draft Position Paper for the Cathodic Protection Project, Phase 1, District Project 8425. He noted that the second lowest bidder had filed a protest that was subsequently withdrawn. He asked the Committee Members if they would recommend approval of the project to the full Board. Chair Pilecki said yes, Member Causey said no because it exceeded the budgeted amount as currently written. COMMITTEE ACTION: Received the reports and provided input to staff. With regard to recommending that the full Board approve the Cathodic Protection Project, Phase 1, District Project 8425, the Committee vote was split (Pilecki -Yes; Causey -No.) *8. Review a summary of the District's Collection System construction projects which were awarded from 2003 to present; review design and construction costs as it relates to industry standards Mr. Petit handed out a spreadsheet (copy attached) of construction projects for the District's Collection System from 2003 to present. It compared design costs, construction management costs, and total project delivery costs with industry Engineering & Operations Committee Action Summary August 25, 2014 Page 5 standards for the indicated time period. In the category of "lessons learned, "he said staff is going to start tracking costs associated with the "public relations" aspect of capital projects (the costs of contacting customers before, during and after construction), and survey costs (currently a part of design costs). He also said staff is assessing its approach to property acquisitions and right -of -way procedures. Finally, staff is looking at ways to refine the scope of various renovation projects. COMMITTEE ACTION: Reviewed the information and provided input to staff. 9. Announcements a. Future scheduled meetings: Monday, September 22, 2014 at 12:30 p.m. Monday, October 27, 2014 at 12:30 p.m. Monday, November 24, 2014 at 12:30 p.m. b.

The project widened the Bypass Channel, installed a concrete box culvert, and built a gated bypass structure on the Lower Walnut Creek levee along Basin B. Extensive permitting from multiple agencies was required to complete the project. Due to regulatory requirements, the project was kept open for several years beyond the contract acceptance in order to comply with environmental monitoring obligations on the Walnut Creek Channel. Contract contingency was used to fund the regulatory efforts performed by consultants and District staff. 7268 Treatment Plant Facilities Renovations The Treatment Plant Facilities Renovations project is part of an ongoing program in the Treatment Plant. This phase was used to help identify future facility renovation projects in conjunction with the Treatment Plant Asset Management Plan project. Future projects will be created for replacement needs of equipment. 7269 Treatment Plant Asset Management The intent of this project was to develop a capital project forecasting tool for the treatment plant. Asset data was improved in the Computerized Maintenance Management System (CMMS), including service life estimates, condition, consequence of failure, cost estimates, etc. Condition assessments were conducted for concrete structures and asphalt pavement. A desktop evaluation was conducted to inventory the piping within the treatment plant and provide an approximate cost estimate. Three status reports were developed to document the project. The asset management program development is being expanded throughout the District and will continue in the next fiscal year under a new project number. 7272 Aeration System Renovation Several consultant studies were conducted under this project that impacts the aeration process and blowers. Such studies included nitrification and nutrient removal to help develop long term financial capital planning. The project scope was delayed due to significant air savings achieved by the aeration basin renovation project. A future project will be created to address the electrical blower and improvements identified from the analysis conducted under this project. 7283 Fire Protection System Improvements The Fire Protection System Improvements project upgraded the entire Headquarters Office Building fire alarm system and repaired several deficiencies within the treatment plant. The new system has been upgraded to current Americans with Disabilities Act (ADA) and National Fire Protection Agency (NFPA) standards and in compliance with the local Fire Department. Attachment 2 Project Descriptions -- 2014 Closing Projects 7287 Treatment Plant Master Plan Update This project included the Plant of the Future Visioning exercise where two consultants developed conceptual plans for the District to become the Plant of the Future considering current or impending technologies, sustainable practices, and several regulatory scenarios. The proposals and presentations were reviewed by the District and a third -party technical review panel comprised of industry experts. This project also included development and calibration of a wastewater treatment process simulation model using BioWin software and included a summary report describing the process model development and calibration approach. As a result of work accomplished under DP 7287, Plant of the Future Roadmap was included in the FY14/15 CIB to support the Zeolite - Anammox pilot and other efforts on a Master Plan. 7294 Secondary Process Improvements This project identified several scope items that were constructed under separate construction projects or postponed to future projects. These items include replacing Return Activated Sludge (RAS) piping, gates, and future improvements to the waste activated sludge system. 7295 Auxiliary Boiler Burner Upgrade This project retrofitted both treatment plant auxiliary boilers with new ultra -low nitrogen oxides (NOx) burners and other emission controls to meet regulations required by the Bay Area Air Quality Management District. The project results allowed the boilers to meet the current NOx permit limit of 15 ppm. 7296 Solids Conditioning Building Seismic Upgrade Study A report presenting seismic retrofit options to the building and furnaces was completed under this project. However, due to the uncertainty of new regulatory requirements and future solids handling projects, the seismic upgrades are not recommended at this time. This study may be used to help future projects within the Solids Conditioning Building. 7298 Piping Renovations Phase 7 This project was the 7t" phase of a multiple -phase treatment plant piping renovation program. The project included replacement of RAS piping and valves at the clarifiers, Solids Conditioning Building (SCB) centrate piping, ash dust collector, recycled water sluice gates, improvements to the ventilation and odor control at the sludge loading facility, and furnace scrubber water instrumentation improvements. 7313 Solids Handling Equipment Evaluation This project was used to help plan for replacement of the existing centrifuges and to fund a pilot study carried out by a vendor. Staff is continuing to evaluate the equipment. The reports prepared under this project will be helpful to determine future replacement of the centrifuges. Any additional planning, studies or pilots will be conducted under the Centrifuge and Cake Pump Upgrades project. Attachment 2 Project Descriptions -- 2014 Closing Projects COLLECTION SYSTEM PROGRAM Project # Project Title 5773 Smith Road Contractual Assessment District Smith Road Contractual Assessment District (CAD) 2012 -1 designed and constructed approximately 594 linear feet of sanitary sewer pipeline, together with appurtenant work and facilities along Smith Road in Alamo. The project serves 7 residential properties. 5937 Alhambra Valley Assessment Districts This project provided funds for a financing mechanism, Alhambra Valley Assessment Districts (AVADs) for extension of public sewers into areas of the Alhambra Valley currently served by septic tanks. The goals of the AVAD program were to assist property owners with septic tanks to finance the cost of extending and connecting to the public sewer; to avoid future use of septic systems and sewage pumping systems in the Alhambra Valley; and to facilitate direct and indirect connections to the Alhambra Valley trunk sewer. Six neighborhood sewer projects were financed through the AVAD program in 2007 and 2008, but there has been no interest since. If interest renews and the Board chooses to continue the program, new funding will be requested and a new capital program established. 5948 TV Inspection This project was a multi -year effort to gather video and condition data on the gravity pipes within the District's sewer collection system. The inspection data is integrated with the District's Geographic Data Integration (GDI) system, and together with previous inspection data on sewers, adds to the historical record of pipeline condition. The data is used to avert potential sewer overflows by identifying sewers in urgent need of cleaning, and adjusting maintenance schedules to an optimum cleaning frequency. The data is also used to assist in developing the District's Collection System Asset Management Plan. This is the final TV Inspection Project under the capital budget. The CCTV inspection program is now funded in the operations and maintenance budget. 5955 Suspended Pipe Support This project identified and evaluated the 49 pipelines suspended from bridges throughout the District's service area, then evaluated each for compliance with seismic support requirements. Eight pipe support systems were identified as being inadequate by a consultant structural engineer and the support systems were repaired and upgraded. These included seven sanitary sewers and one recycled water line. 5973 North Orinda Sewer Renovations, Phase 4 This project is the fourth phase of multiple phases to renovate sewer pipelines as part of the ongoing Collection System Renovation Program. This project installed approximately 14,700 linear feet of 6 -, 8 -, and 15 -inch sewer lines within the public right of way and in easements in the City of Orinda. This project used a variety of construction methods including pipebursting, sliplining, open cut, and Horizontal Directional Drilling (HDD). The contract contingency was used to repair an additional Attachment 2 Project Descriptions -- 2014 Closing Projects 610 linear feet of sewer lines ranging from 6" to 15" diameter that was identified to be in need of urgent repairs after the contract was awarded. 5995 San Ramon Bypass Pump Under this project, Engineering staff, in consultation with Pump Station staff, evaluated the need for a portable emergency bypass pump for the San Ramon Pumping Station. The evaluation determined that the purchase of the pump, at a cost of $282,000, is not necessary or cost effective at this time. 6003 San Ramon Pumping Station Upgrades The San Ramon Pumping Station Upgrades project replaced a 100 -hp pump with a new 250 -hp pump to convey increasing wastewater flows from development in the Dougherty Valley. 8401 Walnut Creek Sewer Renovations, Phase 9 This project is the ninth phase of multiple phases to renovate sewer pipelines as part of the ongoing Collection System Renovation Program. This project installed approximately 10, 700 linear feet of 6 -, 8 -, and 10 -inch sewer lines within public right of way and in easements in Contra Costa County and in the City of Walnut Creek. Construction methods included pipebursting and open cut. The contract contingency was used to repair sanitary sewer lines that were damaged by others, for urgent repair of a sewer siphon, and for the restoration of a drainage swale that was not identified by the Contra Costa County Flood Control District during the design phase. 8407 Martinez Bypass Pump During this project Engineering Staff, in consultation with Pump Station Staff, specified and purchased a portable emergency bypass pump for the Martinez Pump Station. 8409 Pump Station SCADA O &M Manual As a follow -up to the completion of the Pumping Station Supervisory Control and Data Acquisition ( SCADA) Project, an operation manual for use by the pumping station staff was developed in order to document the operation of the SCADA system. Attachment 2 Project Descriptions -- 2014 Closing Projects GENERAL IMPROVEMENTS PROGRAM Project # Project Title 8225 Imhoff Triangle Development Central San acquired approximately 1.1 acres of land west of the Household Hazardous Waste Facility. Over the years, several possible uses for the property have been proposed. In 2007, a Capital Project was created to look at various alternatives to develop the property. A report was prepared outlining the environmental mitigation steps that would be required to develop the property and several minor improvements, such as fencing, have been made to the parcel. The parcel is currently used as buffer property and there are plans to develop it. 8229 Martinez Easements Central San took over the City of Martinez sewer collection system in 1967. As -built plans and property rights documentation for the system was largely not available. A separate capital project was established in 2008 to track costs associated with researching and documenting property rights associated with sewer lines within the City of Martinez as well as acquiring new easements where needed. This Capital Project supported Martinez Sewer Renovation Phases 2 and 3. Capital costs for Martinez Sewer Renovation Phase 4 are currently being charged directly to that project. 8513 2012 -13 Equipment and Vehicles Acquisition This project provided funding for safe and cost - effective vehicles and equipment for FY 2012 -13. The project did not close at the end of FY 2012 -13 because of the late delivery of one vehicle. RECYCLED WATER PROGRAM Project # Project Title No Recycled Water Projects were closed in 2013 -14.
