Award a construction contract in the amount of $1,056,565 to Telstar Instruments for Plant Control Input and Output (I/O) Replacement, Phase 3 Pump and Blower Building, District Project 100057O��ENTRAL MEETING DATE: OCTOBER 17, 2024 BOARD OF DIRECTORS POSITION PAPER Page 1 of 6 Item 5. SUBJECT: AWARD A CONSTRUCTION CONTRACT IN THE AMOUNT OF $1,056,565 TO TELSTAR INSTRUMENTS, THE LOWEST RESPONSIVE AND RESPONSIBLE BIDDER, FOR THE PLANT CONTROL SYSTEM INPUTAND OUTPUT (1/0) REPLACEMENT, PHASE 3 - PUMP AND BLOWER BUILDING, DISTRICT PROJECT 100057; AND CONSIDER THE PROJECT EXEMPT FROM THE CALIFORNIA ENVIRONMENTAL QUALITYACT (CEQA) SUBMITTED BY: INITIATING DEPARTMENT: NATE MORALES, SENIOR ENGINEER ENGINEERING AND TECHNICAL SERVICES - CAPITAL PROJECTS REVIEWED BY: EDGAR J. LOPEZ, CAPITAL PROJECTS DIVISION MANAGER GREG NORBY, DEPUTY GM - ENGINEERING & OPERATIONS Roger S. Bailey General Manager ISSUE On September 4, 2024, four sealed bids were received and opened for the construction of the Plant Control System 1/0 Replacement, Phase 3 - Pump and Blower Building, District Project 100057 (Project). The Board of Directors (Board) must consider award of the construction contract or reject bids within 50 days of bid opening. BACKGROUND The wastewater treatment plant (plant) primarily uses programmable logic controllers (PLC) connected to 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 cards were installed in the mid-1980s. Today, the number of 1/0 cards in use has grown to nearly 1,800. Approximately 700 of these 1/0 cards are outdated and replacement units cannot be purchased from the manufacturer, and they are no longer supported by their service department. Central San October 17, 2024 Regular Board Meeting Agenda Packet - Page 78 of 209 Page 2 of 6 maintains an inventory of spare 1/0 cards to replace units as they fail, but that spare supply has depleted in recent years. This Project is the third of a multiphase effort to replace outdated PLC hardware with modern Schneider Electric equipment at the plant. The Project will address long-term reliability for the PLC system by replacing 1/0 cards in the Pump and Blower Building area and salvaging the old 1/0 cards to restock inventory. The effort will continue the implementation of modern PLC systems and will match the new systems that were installed during phases 1 and 2 at the Filter Plant and secondary process area. The Project site is identified in Attachment 1. The Project also includes the replacement of a critical 1,000 horsepower variable frequency drive (VFD) for the Final Effluent Pump 3. The existing VFD is obsolete; Central San's maintenance department can no longer purchase replacement parts. Additionally, the Project will replace the aeration turbine vibration systems, rewire motor control center controls, and make various other controls improvements in the Pump and Blower Building. Central San staff prepared the plans and specifications for the Project. The Engineer's estimate for construction was $1,500,000. This Project was advertised on July 17 and July 24, 2024. Four sealed bids ranging from $1,056,565 to $2,451,000 were received and publicly opened on September 4, 2024. The Engineering Department conducted a technical and commercial review of the bids and determined that Telstar I nstruments is the lowest responsive and responsible bidder with a bid amount of $1,056,565. A summary of bids received is shown in Attachment 2. Central San will administer the construction contract and will provide contract management, administration, office engineering, administer submittals and schedules, and provide construction inspection. Pending Board award, the General Manager shall execute the Contract Documents subject to submittal requirements. CEQA Staff has concluded that this Project is exempt from 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. ALTERNATIVES/CONSIDERATIONS The Board may elect to postpone or phase the construction which would require the Board to reject all bids. This is not recommended since there are several project elements that should not be deferred including a critical VFD replacement and associated control equipment and PLC work. If the Final Effluent Pump 3 VFD and PLC scope were bid separately, there would be re -work associated and the costs would ultimately increase. The Plant Control System 1/0 Replacement Project has already been phased to effectively replace equipment while getting the maximum expected life out of the existing equipment, and balancing an adequate spare parts inventory. Additional delays are not recommended. FINANCIAL IMPACTS The total estimated project cost is $1,964,000, which includes planning, design, construction contract, contingency, and construction management costs as shown in Attachment 3. The Project is included in the Fiscal Year 2024-25 Budget on page 284 with a total estimated project budget of $2,800,000. There is adequate funding for the Project and the budget savings will be transferred to the Capital Project contingency account. October 17, 2024 Regular Board Meeting Agenda Packet - Page 79 of 209 Page 3 of 6 Due to the competitive pricing, staff is including a 30 -percent contingency budget since there are significant project savings, and for unforeseen conditions if they arise. COMMITTEE RECOMMENDATION The Engineering and Operations Committee reviewed this matter at its meeting on October 2, 2024 and recommended approval. RECOMMENDED BOARD ACTION Staff recommends the following: 1. Award a construction contract in the amount of $1,056,565 for the construction of the Plant Control System 1/0 Replacement, Phase 3 - Pump and Blower Building, District Project 100057 to Telstar Instruments, the lowest responsive and responsible bidder; and 2. Find that the Project is exempt from CEQA.
