LOPEZ, CAPITAL PROJECTS DIVISION MANAGER JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL SERVICES Roger S. Bailey General Manager ISSUE The Board of Directors (Board) must award the contract or reject bids within 50 days of the bid opening. Authorization is also required for the General Manager to execute the Contract Documents subject to submittal requirements and include up to a 15-percent contingency. BACKGROUND Coronavirus COVID-19 Impact: Plant Control System 1/0 Replacement Project— Phase 2, Secondary Process, District Project 7339B (Project) is expected to start in July 2020 and be completed by December 2020, with the bulk of construction performed beyond August. Staff has included conditions in the Contract Documents that account for the health and safety guidelines provided by the Contra Costa May 21, 2020 Regular Board Meeting Agenda Packet- Page 42 of 505 Page 2 of 7 County latest order, such as provisions and costs associated with handwash stations, personal protective equipment, and other safety items. Staff has sequenced the work and milestones to allow the contractor to complete the contract within the duration of the Project and plans to issue an early administrative Notice to Proceed to procure the equipment. The wastewater treatment plant (plant) primarily uses Quantum Programmable Logic Controllers (PLC) connected to Quantum 1/0 cards manufactured by Schneider Electric. PLC 1/0 cards are critical for equipment and instrumentation communication for process control, monitoring, and data acquisition. The first plant PLC 1/0 card was installed in the mid-1980s. Today, the number of 1/0 cards in use has grown to nearly 1,800. Approximately 900 of these 1/0 cards are outdated and replacement units cannot be purchased from the manufacturer, and they are no longer supported by their service department (software or hardware). Central San has maintained an inventory of spare 1/0 cards to replace units as they fail or need to be reprogrammed and tested, but that spare supply has depleted in recent years. This Project is the second of a multiphase effort to replace PLCs with modern Schneider Electric equipment at the plant. The Project will address long-term reliability for the PLC system by replacing PLCs in the secondary process area, salvaging the PLC 1/0 cards to restock the replacement inventory, and continuing the implementation to modern networking PLC systems and matching the new system that was installed during Phase 1 at the Filter Plant. This Project also includes the replacement of several critical variable frequency drives (VFDs)for the secondary process. This includes six VFDs for the Return Activated Sludge (RAS) pumps and three Waste Activated Sludge (WAS) pumps associated with the North Quad Secondary Clarifiers. I n addition, the six VFDs for RAS pumps for the South Quad Secondary Clarifiers which were recently replaced under the Treatment Plant Piping Renovations, Phase 9 project, will receive updated controls. On December 21, 2017, the Board authorized staff to pre-purchase over$200,000 of PLC hardware for both phases of the Project. This purchase was done at a cost savings of approximately$50,000 and under sole-source procurement with Schneider Modicon as the standard hardware at the plant. Phase 1 required the use of more hardware than originally anticipated, therefore staff will purchase additional matching PLC hardware at a cost of approximately$60,000 to complete Phase 2 from Schneider Modicon. Central San staff prepared the plans and specifications for the Project. The Engineer's estimate for construction was $1,300,000. This Project was advertised on March 31 and April 7, 2020. Nine sealed bids ranging from $1,222,200 to $1,695,000 were received and publicly opened on May 6, 2020. The Engineering Department conducted a technical and commercial review of the bids and determined that Bockmon & Woody Electric Company, Inc. is the lowest responsive and responsible bidder.A summary of bids received is shown in Attachment 2. Central San will administer the construction contract, submittals and schedules, and will provide contract management, administration, office engineering, and construction inspection. CEQA Staff has concluded that this Project is exempt from the CEQA under Central San's CEQA Guidelines Section 15301, since it involves minor alterations to existing public facilities involving no expansion of use, and CEQA Guidelines Section 15302, since it involves replacement of existing public facilities at the same location and with the same purpose.Approval of this Project will establish the Board's independent finding that this Project is exempt from CEQA. ALT ERNAT IVES/CONSIDERAT IONS The Board may elect to postpone or phase the construction which would require that the Board reject all bids. This is not recommended since there are several project elements that should not be deferred May 21, 2020 Regular Board Meeting Agenda Packet- Page 43 of 505 Page 3 of 7 including critical VFD replacements and associated controls equipment and PLC work. If the VFDs and associated PLCs were bid separately, there would be re-work associated and the costs would ultimately increase. The Plant Control System I/O Replacement Project has already been phased to effectively replace equipment while getting the maximum expected life of the existing equipment and balancing an adequate spare parts inventory. Additional delays are not recommended. FINANCIAL IMPACTS The total estimated project cost is $1,861,000, which includes planning, design, PLC hardware purchase, construction contract, contingency, and construction management costs as shown in Attachment 3. Staff plans to purchase the PLC hardware directly as a sole source procurement or through the Contractor depending on the best price received for the equipment. The Project is included in the Fiscal Year(FY) 2019-20 Capital Improvement Budget on page 180 with a total estimated project budget of $4,498,000. There is adequate funding for this phase of the project through FY 2019-20 and FY 2020-21. Staff is recommending a 15-percent contract contingency due to the nature and risks associated with renovation work and to provide for additional work if urgently needed at the plant. COMMITTEE RECOMMENDATION The Engineering and Operations Committee reviewed this subject at the May 12, 2020 meeting and recommended Board approval. RECOMMENDED BOARD ACTION Staff recommends the following: 1. Find that the Project is exempt from CEQA; 2. Award a construction contract in the amount of$1,222,200 for the construction of the Plant Control System I/O Replacement Project— Phase 2, Secondary Process, District Project 73398, to Bockmon & Woody Electric Company, Inc., the lowest responsive bidder; and 3. Authorize the General Manager to execute the Contract Documents subject to submittal requirements and include up to a 15-percent contingency.
