FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: MACARTHUR PUMP STATION REHABILITATION, PROJECT NO. 7-63 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: A. Approve a Professional Design Services Agreement with Dudek to provide engineering services for MacArthur Pump Station Rehabilitation, Project No. 7-63, for an amount not to exceed $1,140,000; and B. Approve a contingency of $114,000 (10%). BACKGROUND Orange County Sanitation District (OC San)operates 15 pump stations that support wastewater conveyance throughout its service area.MacArthur Pump Station is an underground pump station that was constructed in 1965 and is located within an easement in the City of Newport Beach, surrounded by commercial land uses.An existing 21-inch influent pipeline conveys flow into the wet well,and flows exit the pump station through recently constructed 10-inch dual force mains.The facility was last rehabilitated in 1989. RELEVANT STANDARDS ·Comply with California Government Code Section 4526 to engage the best qualified firm “on the basis of demonstrated competence and qualifications” and “negotiate fair and reasonable fees” ·Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting ·Protect OC San assets PROBLEM Due to the age of the pump station,many internal assets are reaching the end of their useful life. Recent inspections and a condition assessment of the facility identified coating failures in the wet well and corrosion within both the wet and dry wells, including corrosion on mechanical equipment. Orange County Sanitation District Printed on 4/14/2026Page 1 of 4 powered by Legistar™ File #:2026-4868 Agenda Date:4/22/2026 Agenda Item No:5. PROPOSED SOLUTION Approve a Professional Design Services Agreement to rehabilitate the pump station within the existing footprint,including both the wet well and dry well.The wet well concrete will be rehabilitated and lined.The pump room and electrical rooms within the dry well will also be rehabilitated,including replacement of mechanical and electrical equipment.Improvements to ventilation within the dry well will allow the space to be unclassified.Upon completion,the rehabilitation is expected to extend the service life of the pump station by an additional 20 to 30 years. TIMING CONCERNS Delaying approval of this agreement would postpone the start of design and subsequent construction activities.Any delay in initiating the rehabilitation may allow the existing deteriorated conditions within the pump station to continue progressing and could impact the long-term reliability of the facility. RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,the existing deterioration within the pump station will continue to progress. Continued degradation of coatings,structural elements,and mechanical equipment could eventually lead to equipment failures,increased maintenance needs,or unplanned repairs that may disrupt pump station operations. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION Consultant Selection: OC San requested and advertised for proposals for MacArthur Pump Station Rehabilitation,Project No.7-63 on October 28,2025.The following evaluation criteria were described in the Request for Proposals (RFP) and used to determine the most qualified Consultant.

INDEMNIFICATION To the fullest extent permitted by law, CONSULTANT shall indemnify, defend (at CONSULTANT’s sole cost and expense and with legal counsel approved by OC SAN, which approval shall not be unreasonably withheld), protect and hold harmless OC SAN and all of OC SAN’s officers, directors, employees, consultants, and agents (collectively the “Indemnified Parties”), from and against any and all claims, damages, liabilities, causes of action, suits, arbitration awards, losses, judgments, fines, penalties, costs and expenses (including, without limitation, attorneys’ fees, disbursements and court costs, and all other professional, expert or CONSULTANT’s fees and costs and OC SAN’s PDSA PROJECT NO. 7-63 Revised 050625 MACARTHUR PUMP STATION REHABILITATION Page 17 of 20 general and administrative expenses; individually, a “Claim”; collectively, “Claims”) which may arise from or are in any manner related, directly or indirectly, to any work performed, or any operations, activities, or services provided by CONSULTANT in carrying out its obligations under this Agreement to the extent of the negligent, recklessness and/or willful misconduct of CONSULTANT, its principals, officers, agents, employees, CONSULTANT’s suppliers, CONSULTANT, Subconsultants, subcontractors, and/or anyone employed directly or indirectly by any of them, regardless of any contributing negligence or strict liability of an Indemnified Party. Notwithstanding the foregoing, nothing herein shall be construed to require CONSULTANT to indemnify the Indemnified Parties from any Claim arising solely from: (A) the active negligence or willful misconduct of the Indemnified Parties; or (B) a natural disaster or other act of God, such as an earthquake; or (C) the independent action of a third party who is neither one of the Indemnified Parties nor the CONSULTANT, nor its principal, officer, agent, employee, nor CONSULTANT’s supplier, CONSULTANT, Subconsultant, subcontractor, nor anyone employed directly or indirectly by any of them. Exceptions (A) through (B) above shall not apply, and CONSULTANT shall, to the fullest extent permitted by law, indemnify the Indemnified Parties, from Claims arising from more than one cause if any such cause taken alone would otherwise result in the obligation to indemnify hereunder. CONSULTANT’s liability for indemnification hereunder is in addition to any liability CONSULTANT may have to OC SAN for a breach by CONSULTANT of any of the provisions of this Agreement. Under no circumstances shall the insurance requirements and limits set forth in this Agreement be construed to limit CONSULTANT’s indemnification obligation or other liability hereunder. The terms of this Agreement are contractual and the result of negotiation between the parties hereto. Accordingly, any rule of construction of contracts (including, without limitation, California Civil Code Section 1654) that ambiguities are to be construed against the drafting party, shall not be employed in the interpretation of this Agreement. 23. DUTY TO DEFEND The duty to defend hereunder is wholly independent of and separate from the duty to indemnify and such duty to defend shall exist regardless of any ultimate liability of CONSULTANT and shall be consistent with Civil Code Section 2782.8. Such defense obligation shall arise immediately upon presentation of a Claim by any person if, without regard to the merit of the Claim, such Claim could potentially result in an obligation to indemnify one or more Indemnified Parties, and upon written notice of such Claim being provided to CONSULTANT. Payment to CONSULTANT by any Indemnified Party or the payment or advance of defense costs by any Indemnified Party shall not be a condition precedent to enforcing such Indemnified Party’s rights to indemnification hereunder. In the event a final judgment, arbitration, award, order, settlement, or other final resolution expressly determines that the claim did not arise out of, pertain to, or relate to the negligence, recklessness, or willful misconduct of the CONSULTANT, to any extent, then OC SAN will reimburse CONSULTANT for the reasonable costs of defending the Indemnified Parties against such claims. PDSA PROJECT NO. 7-63 Revised 050625 MACARTHUR PUMP STATION REHABILITATION Page 18 of 20 CONSULTANT’s indemnification obligation hereunder shall survive the expiration or earlier termination of this Agreement until such time as action against the Indemnified Parties for such matter indemnified hereunder is fully and finally barred by the applicable statute of limitations. 24. CONSULTANT PERFORMANCE The CONSULTANT’s performance shall be evaluated by OC SAN. A copy of the evaluation shall be sent to the CONSULTANT for comment. The evaluation, together with the comments, shall be retained by OC SAN and may be considered in future CONSULTANT selection processes. 25. COMPLIANCE WITH OC SAN POLICIES AND PROCEDURES CONSULTANT shall comply with all OC SAN policies and procedures, including, but not limited to, the Contractor Safety Standards, as applicable, and Human Resources Policies, all as may be amended from time to time. 26. CLOSEOUT When OC SAN determines that all work authorized under the Agreement is fully complete and that OC SAN requires no further work from CONSULTANT, or the Agreement is otherwise terminated or expires in accordance with the terms of the Agreement, OC SAN shall give the Consultant written notice that the Agreement will be closed out. CONSULTANT shall submit all outstanding billings, work submittals, deliverables, reports or similarly related documents as required under the Agreement within thirty (30) days of receipt of notice of Agreement closeout. Upon receipt of CONSULTANT’s submittals, OC SAN shall commence a closeout audit of the Agreement and will either: i. Give the CONSULTANT a final Agreement Acceptance: or ii. Advise the CONSULTANT in writing of any outstanding item or items which must be furnished, completed, or corrected at the CONSULTANT’s cost. CONSULTANT shall be required to provide adequate resources to fully support any administrative closeout efforts identified in this Agreement. Such support must be provided within the timeframe requested by OC SAN. Notwithstanding the final Agreement Acceptance the CONSULTANT will not be relieved of its obligations hereunder, nor will the CONSULTANT be relieved of its obligations to complete any portions of the work, the non-completion of which were not disclosed to OC SAN (regardless of whether such nondisclosures were fraudulent, negligent, or otherwise); and the CONSULTANT shall remain obligated under all those provisions of the Agreement which expressly or by their nature extend beyond and survive final Agreement Acceptance. Any failure by OC SAN to reject the work or to reject the CONSULTANT’s request for final Agreement Acceptance as set forth above shall not be deemed to be acceptance of the work by OC SAN for any purpose nor imply acceptance of, or agreement with, the CONSULTANT’s request for final Agreement Acceptance.

BACKGROUND The existing MacArthur Pump Station (Exhibit 19 – Project Reference Material) is an underground pump station that was built in 1965 and is located on an easement in the City of Newport Beach. The existing pump station is surrounded by commercial land use and is accessed from the west side of MacArthur Blvd, approximately 500 feet north of Von Karman Avenue (Figure 1 – Project Location Map). An existing 21-inch influent pipe conveys flow into the wet well. The existing 12-inch forcemain exiting the pump station was abandoned and replaced with a 10-inch dual forcemain by Project 7-68 (Exhibit 19 – Project Reference Material). In addition, as part of Project 7-68, the existing valve vault was removed and replaced. The assets within the existing pump station are reaching the end of their useful life and require replacement or rehabilitation. A condition assessment of the pump station revealed exposed aggregate with ½”-1” of soft concrete, corroded steel, and corrosion stains in the wet well, and observed significant coating failures and corrosion on the pump supports, pump suction pipe sections, pipe supports, pump casings, and discharge pipes. See Exhibit 19 – Project Reference Material for an evaluation of the existing pump station. A structural evaluation of the pump station found that the overall pump station structure appeared to be in condition, however, moisture intrusion was observed, likely due to groundwater. See Exhibit 19 – Project Reference Material for a structural evaluation of the pump station. For these reasons, OC SAN has decided to rehabilitate the pump station within the boundaries of the existing footprint, extending the life of the existing pump station without a full replacement for another 20 to 30 years. March 2026 7-63 – Design SOW Page 6 of 41 Figure 1 – Project Location Map GENERAL PROJECT DESCRIPTION The project consists of rehabilitating the existing wet well concrete, replacing all existing internal equipment in the pump station and electrical rooms, addressing area classification, and repairing the pump room and electrical room walls. PROJECT EXECUTION PHASES All OC SAN projects are divided into six phases. CONSULTANT shall provide engineering services for all Project Elements listed in this Scope of Work for the following Phases: Phase 1 – Project Development (Not in this Scope of Work) Phase 2 – Preliminary Design Phase 3 – Design Phase 4 – Construction (Not in this Scope of Work) Phase 5 – Commissioning (Not in this Scope of Work) Phase 6 – Close Out (Not in this Scope of Work) DESCRIPTION OF PROJECT ELEMENTS Detailed descriptions of the Project Elements are presented below. 1.4.1 PROJECT ELEMENT 1 – WET WELL REHABILITATION A. The existing soft concrete on the surface of the wet well will be rehabilitated and the internal surface will be lined. March 2026 7-63 – Design SOW Page 7 of 41 B. Assumptions for Level of Effort 1. For the purpose of estimating the predesign and design phase levels of effort, the CONSULTANT shall make the following assumptions regarding this project element: a. Suction bell elbows will be replaced. b. The existing bubbler system will be demolished and removed in this project. One existing ultrasonic transmitter and one radar level transmitter are to be protected in place. 1.4.2 PROJECT ELEMENT 2 – PUMP ROOM REHABILITATION A. The pump room rehabilitation element consists of the replacement of all internal mechanical equipment. Flowrates (MGD) are shown in the table below: Reported Capacity 2017 PDWF 2017 PWWF 2040 PDWF 2040 PWWF 3.6 1.7 2.3 2.0 2.5 B. The pump room will house the following components and provide the necessary access required for operations and maintenance: 1. Replace existing pumps with (2) dry submersible main sewage pumps (One duty pump and one standby pump – the same size) with pump motors controlled by variable frequency drives (VFDs) that are equipped with constant speed bypass mode of operation. 2. Replace submersible, non-clog sump pump 3. Replace suction, header, discharge pipe, wall spool, wall pipe penetration, pipe supports, and associated valves 4. New flow meter C. Assumptions for Level of Effort 1. For the purpose of estimating the predesign and design phase levels of effort, the CONSULTANT shall make the following assumptions regarding this project element: a. All new equipment will be replaced within the same footprint. 1.4.3 PROJECT ELEMENT 3 – ELECTRICAL ROOM IMPROVEMENTS A. Replace all existing electrical, mechanical and control equipment including but not limited to the following: 1. (2) Motor control centers (MCCs) 2. (2) Variable frequency drives (VFDs - included with Constant Speed Bypass) 3. Metering Switchboard 4. Utility Switchboard 5. Transformer 6. Panelboards 7. Distributed control system (DCS) Controller 8. Remote Input/Output (RIO) Cabinet (included with DCS Controller) 9. Uninterruptable power supply (UPS) 10. Replace existing selector switch panel and level instruments March 2026 7-63 – Design SOW Page 8 of 41 11. DCS server cabinet with front and rear floor access 12. Redundant DCS servers and supporting communications equipment 13. Operator workstation cabinet 14. Go/No-Go Panel, Lighting and Signage (New) B. Assumptions for Level of Effort 1. For the purpose of estimating the predesign and design phase levels of effort, the CONSULTANT shall make the following assumptions regarding this project element: a. The Level Measurement system is to be replaced with a combination Ultrasonic and Radar Level Monitoring System per Project No. FE23-03 and to be completed prior to this project. The transmitter panel of the combination ultrasonic and radar level measurement system may need to be re-used and relocated to accommodate for the installation of the new electrical and mechanical equipment in the electrical room. The existing bubbler panel and air compressors will be demolished and removed as part of this project. b. All new equipment will be installed within the existing footprint of the electrical room. 1.4.4 PROJECT ELEMENT 4 – ADDRESS HAZARDOUS AREA CLASSIFICATION A. The existing electrical room does not meet the current fire code and is classified as Class 1 Division 2. There is one existing aboveground supply fan, (1) 14” diameter supply duct in the pump room, and (1) 8” diameter exhaust duct in the electrical room. The existing ventilation system will be replaced with (1) duty and (1) standby fan that meet CCR Title 8 regulations, NFPA 820 and OC SAN design guidelines to declassify the electrical room. 1.4.5 PROJECT ELEMENT 5 – WALL REPAIRS A. The dry well and electrical room wall cracks will be sealed and repaired to prevent corrosion of the wall reinforcing. 1.4.6 TEMPORARY FACILITIES DURING CONSTRUCTION A. In certain cases, construction sequencing constraints may require the Contractor to construct a temporary facility to be used during a certain portion of the construction period. CONSULTANT shall identify in what instances such facilities are required or reasonably warranted and present those instances with implementation plans and construction sequencing constraints to OC SAN for consideration. When such facilities are found to be either required or reasonably warranted, CONSULTANT shall provide sufficiently detailed drawings and specifications to be included in the Bid Documents that bidders understand what is required to provide and potentially operate the temporary facilities and that the reliability and performance of the facilities will meet OC SAN’s needs and reasonably mitigate construction risks. Examples of potential facilities include: 1. A bypass pumping system will be required for temporary handling of flows during construction. Influent flows will be captured at the upstream manhole (SUN0155-0285) and fed to the downstream dual 10” forcemains in the existing valve vault. Manhole SUN0155- 0285 is located in the sidewalk within OC SAN’s easement. The temporary bypass pumping system must comply with OC SAN’s goal of zero sewage spills. 2. Temporary MCC or 480V panelboard to install new electrical equipment 3. Temporary standby power to accommodate the transfer of electrical loads from existing electrical equipment to new electrical equipment and the phasing of the electrical system from the existing standby power electrical distribution equipment and synchronizing controls to the new synchronizing switchgear. March 2026 7-63 – Design SOW Page 9 of 41 1.4.7 COORDINATION WITH OTHER PROJECTS A. The following projects may impact or require coordination with this project. The CONSULTANT shall coordinate with each project and incorporate work restrictions and requirements in the design documents. 1.

Replace the entire section with the following: CONSULTANT shall perform a RUN evaluation for all pumping systems according to ANSI/HI 9.6.8-2014 or latest (Rotodynamic Pumps—Guideline for Dynamics of Pumping Machinery), to assess various vibration related phenomena. RUN is the general term used to denote the quantity obtained from multiplying the Risk (R) value and Uncertainty (U) value determined during the appropriate evaluation. This evaluation will help determine the relevant analysis level required to appropriately evaluate pumping machinery construction attributes and relevant site characteristics. CONSULTANT shall obtain (from the manufacturers of the rotating equipment) or calculate (based on anticipated turning speeds, operational requirements, etc.) the relevant equipment and system natural and/or excitation frequencies. These frequencies will include any effect from the various torsional, lateral, and structural behaviors of the equipment or system. All other rotating equipment such as fans, blowers, compressors, and pumps/equipment not covered by other standards or specifications, etc. shall undergo a similar evaluation to determine relevant risk and analysis requirements to ensure project success and reliability targets are met. For these other types of rotating equipment not covered by other standards or specifications, the CONSULTANT shall propose a plan for OC SAN to approve prior to analysis being performed accordingly. For the purpose of estimating level of effort, the Risk Value, “R”, for critical equipment that is required for continuous operation of a process system or where standard equipment is modified slightly for this application, a R-Value of 4 should be assumed. For systems dedicated to a redundant process train or where standard equipment is used, a R-Value of 2 should be assumed. The results from the above RUN evaluation shall be used by the CONSULTANT in their subsequent design, to help provide a robust solution for the project needs. Iterations of design and equipment substitutions shall trigger additional RUN evaluations and analysis, as needed. Final equipment acceptability and commissioning shall be per ANSI/HI 9.6.4-2009 or latest (Rotodynamic Pumps—for Vibration Measurements and Allowable Values), applicable Part of ISO 10816 latest (Mechanical Vibration), ANSI/AMCA 204-05:2012 or latest (Balance Quality and Vibration Levels for Fans), ISO 1940-1:2003 or latest (Mechanical Vibration—Balance Quality Requirements for Rotors in a Constant (Rigid) State), and ISO 21940-12:2016 or latest (Mechanical Vibration— March 2026 7-63 – Design SOW Page 40 of 41 Rotor Balancing—Procedures and Tolerances for Rotors with Flexible Behavior) as applicable. In addition, all loads, forces and moments imparted to equipment or piping, including resonance, shall be fully mitigated and all usage cases analyzed and documented per ASME 31.3-2018 or latest (Process Piping) at a minimum, and properly designed within applicable allowable stresses, etc. If there are conflicts in the standards specified, the more stringent value or condition to prevail. 9.

OPERATIONS COMMITTEE Agenda Report Headquarters 18480 Bandilier Circle Fountain Valley, CA 92708 (714) 593-7433 File #:2026-4870 Agenda Date:4/22/2026 Agenda Item No:6. FROM:Robert Thompson, General Manager Originator: Riaz Moinuddin, Director of Operations & Maintenance SUBJECT: CENTRAL GENERATION ENGINE NO. 1 INSPECTION AND REPAIRS, SPECIFICATION NO. BSS -2026-728BD GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: A. Approve a Sole Source Service Contract with Cooper Machinery Services LLC for inspection and field service repairs to Central Generation (Cen Gen) Engine No. 1, Specification No. BSS -2026-728BD, for a total amount not to exceed $142,923, plus applicable sales tax and freight; and B. Approve additional allowance funding not to exceed $120,000 for associated repairs that may be required due to the high potential for additional damage identified during disassembly and inspection. BACKGROUND The Orange County Sanitation District (OC San)has eight clean-burning internal combustion engines that are used to generate electricity for both treatment plants.These engines play a vital role in OC San’s emissions reduction and South Coast Air Quality Management District permit compliance by converting biogas into electricity and process heat.This engine was rebuilt several years ago by a non-Original Equipment Manufacturer (OEM)vendor with non-OEM parts.It experienced a catastrophic failure.It was later rebuilt by Cooper Machinery Services LLC,but the cylinder liners were not replaced at the time. On January 27,2026,Cen Gen at Plant No.1,Engine No.1,had a premature failure in cylinder 3.A preliminary investigation determined that the piston had worn into the cylinder liner,causing excessive heat and pressure in the crankcase. RELEVANT STANDARDS ·24/7/365 treatment plant reliability ·Maintain a proactive asset management program ·Operate and maintain facilities to minimize impacts on surrounding communities,including odor, noise, and lighting Orange County Sanitation District Printed on 4/14/2026Page 1 of 3 powered by Legistar™ File #:2026-4870 Agenda Date:4/22/2026 Agenda Item No:6. PROBLEM Due to a leak and significant damage to cylinder 3,Engine No.1 is currently inoperable.Field repairs and further inspection are required to assess the extent of the damage and determine if any additional repairs are needed. PROPOSED SOLUTION Approve a Sole Source Service Contract to the OEM to disassemble, inspect, and repair the engine. TIMING CONCERNS Delays in completing repairs would increase the risk of plant process interruptions. RAMIFICATIONS OF NOT TAKING ACTION Failing to act would leave plant operations without essential backup equipment for heating digesters and electricity generation,increasing the risk to process reliability and the potential for sewage spills. Extended downtime could also disrupt power production and compromise permit compliance. PRIOR COMMITTEE/BOARD ACTIONS August 2017 -Received and filed Orange County Sanitation District purchases made under the General Manager’s authority for the period of April 1,2017 to June 30,2017;and approved the following additions to the pre-approved Original Equipment Manufacturer (OEM)Sole Source List:… Cooper Bessemer - CenGen engine components. ADDITIONAL INFORMATION Cooper Machinery Services LLC (formerly Cooper-Bessemer)is the OEM for all parts and services related to Cooper-Bessemer engines.A $120,000 allowance is intended to address potential additional engine damage, tariffs, or other unforeseeable costs. CEQA N/A FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget Update FY 2025-26,Page 33,Repair &Maintenance)and the budget is sufficient for the recommended action.

FROM:Robert Thompson, General Manager Originator: Riaz Moinuddin, Director of Operations & Maintenance SUBJECT: MASTER REIMBURSEMENT AGREEMENT FOR MANHOLE FRAME AND COVER OVERLAY GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: A. Approve a Master Reimbursement Agreement with the City of Cypress, Specs. S-050A, S-055, and S-055A, establishing terms, procedures, and reimbursement for Orange County Sanitation District manhole frame and cover adjustments performed as part of Cypress Street Rehabilitation projects, in a standardized form approved by General Counsel; and B. Approve the Master Reimbursement Agreement Template and authorize the General Manager to execute future Master Reimbursement Agreements with other municipalities under similar terms, as approved by General Counsel. BACKGROUND Many municipalities routinely undertake street improvement projects to enhance pavement quality and roadway safety.These projects generally include asphalt resurfacing and related upgrades within existing rights-of-way. Orange County Sanitation District (OC San)owns and maintains approximately 4,400 manholes within the Orange County service area.As part of pavement resurfacing,these manholes often require elevation adjustments to meet final roadway grade.OC San is responsible for ensuring proper elevation to maintain both traffic safety and sewer system accessibility. Incorporating OC San’s manhole adjustment work into a municipality’s project scope is more efficient in terms of labor,time,and cost than performing the work separately.Under these agreements,OC San reimburses the municipality for the adjustment work. RELEVANT STANDARDS ·Protect OC San assets ·Maintain collaborative and cooperative relationships with regulators, stakeholders, and neighboring communities Orange County Sanitation District Printed on 4/14/2026Page 1 of 3 powered by Legistar™ File #:2026-4871 Agenda Date:4/22/2026 Agenda Item No:7. ·Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard PROBLEM OC San must currently negotiate and execute a separate reimbursement agreement for each municipal street rehabilitation project requiring manhole adjustments.This repetitive process is labor -intensive, time-consuming, and may delay project delivery. PROPOSED SOLUTION Approve a Master Reimbursement Agreement with the City of Cypress and approve a Master Reimbursement Agreement Template to establish standardized reimbursement terms and streamline the approval process by authorizing the General Manager to execute future qualifying agreements. TIMING CONCERNS N/A RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,OC San will need to negotiate separate reimbursement agreements with multiple municipalities for each project,potentially causing delays.If OC San instead publicly bids and performs the work independently,costs would likely be higher due to restricted access to construction areas and additional street closures impacting the public. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION Under the agreement,OC San will supply manhole frames and covers and perform inspections to ensure the work meets OC San standards. CEQA N/A FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget Update FY 2025-26,Page 33,Repairs &Maintenance)and the budget is sufficient for the recommended action.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: HEADWORKS ELECTRICAL DISTRIBUTION IMPROVEMENTS AT PLANT NO.2,PROJECT NO. P2-141 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: A. Approve a project budget increase of $11,848,000 for Headworks Electrical Distribution Improvements at Plant No. 2, Project No. P2-141, for a total project budget of $46,500,000; B. Approve a Progressive Design-Build Contract with Big Sky Electric, Inc./Filanc, a Joint Venture, to provide Phase 1 progressive design-build services for Headworks Electrical Distribution Improvements at Plant No. 2, Project No. P2-141, for an amount not to exceed $3,902,200; and C. Approve an upper limit for this Contract of $39,710,000, which includes contingency. BACKGROUND The headworks of a wastewater treatment plant is where incoming sewer flows converge through a series of pipes,meters,flow diversions,and gates as part of the preliminary treatment process.At Orange County Sanitation District’s (OC San)Reclamation Plant No.2,the headworks blends sewage from four trunk lines before it enters the treatment process. Distribution Center H (DC-H) at Plant No. 2 houses the electrical distribution equipment that provides power and control to the headworks facilities through its switchgear and motor control centers.Power and control cables from DC-H are routed to the headworks process areas through an underground duct bank system that connects the various facilities. RELEVANT STANDARDS ·24/7/365 treatment plant reliability ·Ensure the public’s money is wisely spent ·Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard Orange County Sanitation District Printed on 4/14/2026Page 1 of 7 powered by Legistar™ File #:2026-4872 Agenda Date:4/22/2026 Agenda Item No:8. PROBLEM Over the past five years,several critical pieces of equipment at the headworks facilities have experienced shutdowns due to a steadily increasing rate of low-voltage power and control cable failure.Initially,failed cables were replaced through the execution of numerous smaller cable replacement projects, and nearly all spare conductors and conduits have been utilized. A condition assessment of the underground duct bank system identified several existing and spare conduits as blocked and unusable due to the failure of the fiberglass conduits.The ability to reuse existing underground conduits is significantly constrained. Recently,temporary replacement cables have been routed above ground due to the lack of available buried duct bank conduits.These temporary installations create operational and safety concerns, including potential tripping hazards,roadway restrictions,and reduce the reliability of the headworks electrical distribution system. In addition to the cable failure issues,variable frequency drives for the seven (7)main sewage pumps and sixteen (16)odor control fans are obsolete and have reached the end of their useful life. The main sewage pump vibration monitoring is also obsolete. PROPOSED SOLUTION Approve a Progressive Design-Build (PDB)contract to replace and reroute all low-voltage power and control cables serving the headworks.The project will also replace obsolete variable frequency drives and vibration monitoring equipment. TIMING CONCERNS Delaying approval of this contract will postpone the replacement of failed or failing cables,obsolete variable frequency drives,and obsolete vibration monitoring equipment,which could affect the operational reliability of the headworks facilities at Plant No. 2. RAMIFICATIONS OF NOT TAKING ACTION Based on experience,if no action is taken,it is anticipated that cable failures will continue to affect the reliability of the headworks facilities at Plant No.2.The variable frequency drives could fail, resulting in an urgent project to replace them.The vibration monitoring equipment could also fail, resulting in lack of critical equipment protection.The above-ground cable installations will remain in place due to the lack of available conduits,creating ongoing safety concerns such as tripping hazards and limiting safe access for operations and maintenance staff.

The Best-Value Proposer was selected based on a range of factors,including technical design, construction expertise,financial record,skilled labor force availability,safety record,and competitive fee. In its technical proposal and oral interview,Big Sky Electric,Inc./Filanc,a Joint Venture, demonstrated a clear understanding of the scope of work,strong technical capabilities as well as a novel design alternative and procurement approach that can advance project completion.The team also demonstrated familiarity with Reclamation Plant No.2 and experience coordinating with Operations and Maintenance staff,which will support a collaborative project environment,minimize risks, and expedite project delivery. Therefore,the Evaluation Team determined that Big Sky Electric,Inc./Filanc,a Joint Venture,is the best-value and most qualified Design-Builder to successfully complete the scope of work. Negotiations: Based on the Evaluation Committee’s recommendation,the Director of Engineering authorized the start of negotiations on December 18,2025,with the highest-ranking proposer,Big Sky Electric, Inc./Filanc, a Joint Venture. Staff conducted negotiations with Big Sky Electric,Inc./Filanc,a Joint Venture,to clarify the scope of work,contractual requirements,key assumptions,and the proposed approach to meet the goals and objectives for the project. Several meetings were held during negotiations.The scope was revised to include additional vibration monitoring design services for the existing Main Sewage Pumps (MSPs).Scope assumptions were better clarified, and the Phase 1 schedule was updated accordingly. Original Amount Final Negotiated Amount Phase 1 Services $3,988,000 $3,902,200 The Design-Builder proposed several exceptions to the contract,including provisions related to limitation of liability and indemnification.These exceptions were reviewed,revised,and approved during negotiations by the Legal Counsel and Risk Management teams from both OC San and the Design-Builder. Based on the results of these negotiations,staff determined that the final negotiated fee is fair and reasonable for this project and recommends awarding the PDB Contract to Big Sky Electric, Inc./Filanc, a Joint Venture. The main sewage pump vibration monitoring equipment was added after the original construction budget was established.The variable frequency drive cost estimate had incorrect costs entered for material and labor.Together,these cost differences total approximately $10M.Additionally,copper prices have increased approximately 25%in the past year.Finally,the Phase 1 cost was based on a lower construction cost,and did not include the detailed field investigation work recommended by the Design-Builder.A budget increase of $11,848,000 is recommended to provide sufficient funds for the PDB contract upper limit.
