SUBJECT: CIP NOS. 8320, 8321, 8324 & 8345 RACEWAY BASIN AND BUENA CREEK PUMP

STATIONS IMPROVEMENTS AND FOG ABATEMENTS PROJECT - FIRST AMENDMENT TO THE AGREEMENT WITH GSE CONSTRUCTION COMPANY, INC.

Faraday Ave. The BCPS and RBPS are owned by Buena Sanitation District (BSD) and City of Vista (CoV); however, the pump stations are operated and maintained by Encina Wastewater Authority (EWA) by contract.

Both stations are experiencing routine Fats, Oils, and Grease (FOG) accumulation in the wet wells that negatively impact station efficiency and downstream pipelines. The EWA operation and maintenance (O&M) staff spend numerous hours per week breaking down the FOG build up in the wet wells. Staff use high pressure water hoses to break down the FOG mat and increase pump speed to drain the wet well to disperse the FOG mat. In 2021, the City of Vista and Buena Sanitation District contracted with HDR Engineering to prepare a study that carefully evaluated several different technologies against robust evaluation criteria and found that a large volume air bubble mixer by Pulsed Hydraulics, Inc. (PHi) to be the best alternative to mitigate the FOG accumulation issue at BCPS and RBPS (CIP 8324 and CIP 8320).

Installation of the system requires the design and implementation of a temporary station bypass, which is part of the proposed scope of work.

A May 2021 condition assessment and October 2021 site assessment of the Buena Creek Pump Station identified required mechanical modifications (CIP 8345) including replacement of 24 valves to ensure proper operation and ability to isolate various pumps in the station. In addition, there are several suction valves that are leaking. These valves are direct replacements but also require the design and implementation of a temporary station bypass associated with the project.

The BCPS force main manifold piping includes some ability to isolate pumps three, four, and five for maintenance purposes, however, pumps one and two lack such ability. As part of CIP 8345, the design build team analyzed and will construct modifications to the BCPS manifold piping to allow for future isolation of each side of the force main manifold so that future valve maintenance can be achieved without externally bypassing the pump station, resulting in increased resilience and efficiency of future maintenance activities.

Lastly, the Raceway Pump Station Emergency Overflow Basin Improvements project (CIP 8321) addresses groundwater, or other water sources entering the emergency overflow basin at the Raceway Pump Station which reduces storage volume and causes potential vector control issues. The main objectives of this project are to eliminate and/or reduce the source of groundwater with a subdrain system, utilize injection grouting to seal cracks in the basin, and reseal the overflow basin with an appropriate lining method.

First Amendment to the Design -Build Agreement. On May 13, 2025, the City Council and District Board awarded the Design -Build Team (DBT) of GSE Construction Company, Inc. (GSE) the design portion of the project. The DBT has completed the design, and staff has negotiated a Guaranteed Maximum Price (GMP) with the DBT and recommends approval of the first amendment to establish the GMP of $1,752,094. The proposed amendment to the agreement with GSE establishes the GMP and allows the DBT to begin Phase 2 construction, operation/startup services as specified in the original agreement (Exhibit 4).

FISCAL IMPACT: The cost of this amendment is $1,507,622, which covers construction costs for the project. Phase 1 design services were $244,472, which brings the new contract ceiling to $1,752,094 for GSE to provide design -build services for the design and construction of the Raceway Pump Station and Buena Creek Pump Station Improvements and FOG Abatements Project, Phase 2. Sufficient funding is budgeted and available in the Fiscal Years 2024/25 and 2025/26 Capital Improvement Budgets in Source Appropriation Account Nos.5036620.578999.8320, 5036620.578999.8321, 5066515.578999.8324, and 5066515.578999.8345.

PHI would be pleased to provide the following equipment to meet the mixing requirements of the Large Bubble Mixing System for the City of Vista, CA. Pulsed Hydraulics Inc. will supply a standard product that will meet the functional intent of removing grease and reducing odors.

SCOPE:

The PHI variable speed mixing system is a patented method of mixing pump stations via injection of compressed air by pneumatic/electric valves through specifically spaced bubble forming plates anchored to the bottom of the pump stations. A factory - programmed controller operates the injection process.

Compressed air is injected as a very short -duration pulse or burst in order to form a large bubble air mass, which, as it rises to the surface, forms a powerful and thorough mixing action. Each injection valve is connected to bubble forming plates with one -inch diameter piping made of suitable material for the liquid being mixed and for the air pressure utilized. Two mixing systems will be supplied for this project. One for Buena Pump Stations 1 & 2 and one for Raceway Pump Station.

EQUIPMENT:

A. Bubble Forming Plates (BFPs) — The project will include seven (7) 8 -inch diameter 304 stainless steel BFPs.

A BFP consists of two disks separated approximately 3/8 inch apart by internal spacers. Air is injected through a 1 -inch NPT threaded nipple in the top disk to the space between the disks, where it is forced laterally to form the mixing air mass.

Three 3/8 -inch diameter, equally spaced pre -drilled holes are used for anchoring the BFP to the tank bottom. A drawing of a BFP accompanies this proposal. BFPs can be leveled by using threaded bolts with leveling nuts.

B. PHI Mixing Valve Enclosures (MVEs) — PHI will supply two (2) model PHI 354 MVEs.

1. The MVE is made of 304 SST and is NEMA 4X rated.

2. The MVE will have injection valves, which are solenoid -controlled and pilot - air -assisted. The valve body and manifold base will be made of anodized aluminum. Seals will be Nitrile/Buna-N. The valve will be a positive -sealing poppet valve designed to be self -compensating for wear and non -tubed service. Ross Controls will supply the valve.

3. The controller is a PLC by Automation Direct.

4. A 7 -inch color touchscreen OIT shall be mounted on the MVE door. The OIT shall allow operators to change pulse frequency, pulse duration (open/close cycle timing), valve pulse order, and valve operation mode (intermittent, continuous, or off). A NEMA 4X door will protect the display from the elements when the MVE is mounted outdoors.

5. An air filter with a 50 -micron element and an auto -drain feature is provided to remove particulates and water to protect the regulator and injection valve.

6. A manually adjustable pressure regulator with gauge provides constant pressure for proper airflow to the injection valves. It also allows for adjustment to different air pressures. Pressure to this regulator cannot exceed 175 PSIG nor be less than 30 PSIG. Excessive pressure will damage the regulator seal. Under pressure will not allow the valve to pulse correctly.

7. An electric heater (50 W) is provided when MVEs are located outdoors in cold climates.

8. Components are pre -piped with 304/316 stainless steel pipe and fittings and are factory -tested for leaks and function. Quick disconnect unions are provided for the servicing of components.

9. Each PHI MVE will require a 110 Vac @ 20 -amp electrical service.

8 PH PHi-354 Series
Hydro -Pulse Mixer
Description: The PHI -354 mixer is unique in that it utilizes large air bub- bles which are sequentially injected in a liquid to create powerful mixing currents. The system is contained in an 30" x 24" x 8" NEMA-4X enclosure that consists of three major components."
1) An electro-pneumatic valve which has a high CV valve, allowing it to open and close in milliseconds, which creates a well -formed bubble. 2) A pressure regulator/air filter, with auto -drain, which controls the pres- sure of the mixing air (typically set at 50 psi)
3) A factory programed Automation Direct Click PLC controls the system. 4) HMI (Human Machine Interface) with 7 -inch touchscreen sets pulse duration and frequency. Also provides timer for off/on mixing schedule.

Bubble Forming Plate: The only equipment in-
stalled in the vessel is the forming plate and pip-
ing. The forming plate is an 8 -inch disk consisting
of two 3/16" plates (either stainless steel or PVC,
depending on the product being mixed), which are
separated by 3/16 of an inch and connected to a 1
-inch NPT pipe. Piping is run from the enclosure
and connected to the forming plate. The electro-
pneumatic valve delivers the compressed air
through the piping to the forming plates where it
exits between the two plates, creating a large bub-
ble mass. The mixing is created by the bubble ris-
ing to the top of the vessel, forcing a wave action
to the sides of the vessel, then down the walls of
the vessel and back to towards the middle.

Smaller vessels can be mixed by a single valve
and forming plate, where a larger vessel may take
a number of valves controlling air to an array of
plates in the vessel.

Applications: The PHi-354 is used in wastewater treatment plants to mix sludge holding tanks, aerobic digesters, lift stations, chemical tanks, polishing basins, anoxic basins and aeration basins to enhance oxygen transfer, as well as any other liquid vessel that requires mixing.

The PHi-354 system is NSF -61 approved and used to mix potable water tanks of any size or shape. Complete mixing is accomplished in minutes.

Energy Savings: The PHi-354 uses substantially less energy than mechanical mixers.

2. One firm submitted a proposal and based upon the review of the proposal and interviews with the top firms, Design Builder was selected as the respondent who best met the evaluation criteria specified in the RFP including experience and technical competence, schedule, rates, and financial resources and with whom City could negotiate an agreement.

NOW THEREFORE, in consideration of the mutual promises and covenants contained herein:

THE PARTIES AGREE:

Section 1: General Scope of Work to Be Performed by DB

1.2 The services provided by the DB shall include, but not be limited to, all services outlined and described in this agreement and the design, and construction services within Exhibit 1.

1.3 The DB shall:

1.3.1 Perform design and pre -construction services (Phase I) on a time and materials basis for an amount not -to -exceed $244,472, as specified in DB's Project Cost Estimate.

At 90% complete construction documents the DB shall propose a Guaranteed Maximum Price (GMP) which will include, but not be limited to, the cost for all labor, equipment, and material to design and construct the Phase II Project in accordance with all applicable rules, regulations, and laws. If the Parties agree to DB's proposed GMP, or successfully negotiate an alternative GMP amount, the Parties shall enter into an amendment to this Agreement to fund and undertake Phase II and III of the Project. Under the amendment, the DB fee shall be 10% of the cost of construction defined as the total sum of trade contracts (subcontractors), materials (purchase orders), equipment, self -performed work and general conditions. Any costs incurred by DB in excess of the established GMP shall be the sole responsibility of the DB, unless a Change Order is approved by the City. Any EXHIBIT 4

savings resulting in the project being completed for less than the amount of the GMP shall belong to the City.

1.3.2 Provide the proposed GMP to City by August 11, 2025, and complete the Phase I design services by September 8, 2025, including City approval of 90% construction drawing package, in accordance with the schedule set forth in Exhibit 1.

Section 2: General Obligations of City

2.1.6 Issue Certificate of Substantial Completion when City reasonably determines the Project has achieved Substantial Completion as defined below in Section 16.1.

3.1.2 At all times in performing its services, design and deliver the best possible Project consistent with the standard of care that satisfies the time, monetary, quality and design parameters set forth in this Agreement.

3.1.3 Design and construct the Project on time, consistent with timeframes set forth in the Project Schedule (Exhibit 1), and in such a manner that the GMP or Contract Time of the Project shall not be exceeded, except by written Change Order as provided in Section 14. DB shall provide a master accounting system and matrix using software acceptable to City that will be updated, expanded and provided to the City monthly as the Project develops.

3.1.4 Perform all services as expeditiously as is consistent with reasonable skill and care and shall complete the services within each and all of the time periods set forth in the Project Schedule (Exhibit 1).

3.1.5 Any subcontractors performing Project construction must be appropriately licensed by the California Contractors State License Board or other required agency.

3.1.6 Perform or subcontract all design services for the Project utilizing qualified, licensed and sufficiently experienced engineers, and other professionals ("Design Consultants") as identified in Exhibit 1. DB shall not be permitted to substitute any Design Consultant unless authorized by City. The fact that the City approves the subcontracting of any such services will in no way relieve the DB of any of its obligations or responsibilities under this RFP or this Agreement.

3.1.7 INTENTIONALLY LEFT BLANK

3.1.8 Ensure that DBT personnel conduct themselves in a professional manner at all times. Personnel shall be courteous, neat in appearance, and wear visible identification including all personal protective equipment.

3.1.10 Take all reasonable steps during the course of the Project so as not to interfere with the ongoing operation of the adjacent residences, businesses and facilities, including but not limited to the following:

3.1.10.1 Not interfere with pedestrian and vehicular access.

3.1.10.2 Take all reasonable steps during the course of construction to control dust in accordance with the provisions in the 2012 Edition of the Standard Specifications for Public Works Construction and most recent Supplement ("Greenbook"). Ensure that all work conforms to the City of Vista noise ordinance unless authorized by the designated City representative. The DB shall ensure all DBT personnel comply with all relevant OSHA, Cal/OSHA, and labor and industrial work safety regulations at all times they are on the Project Site. The DB is responsible for implementing confined space entry procedures in accordance with all applicable laws and regulations.

3.1.11 Study all applicable laws, codes, ordinances, rules, orders, regulations, and statutes affecting the Project, including but not limited to, zoning, environmental, building, fire and safety codes and coverage, and lien laws, and comply with them in performance of its services. DB shall ensure that the Project design conforms to all applicable federal, state and local laws, statutes, ordinances, rules, regulations, orders or other legal requirements, (collectively "Governmental Requirements") existing as of the date of this Agreement. However, the City recognizes that Governmental Requirements and their interpretations by governmental officials ("Code Authority") are often subject to change at any time, even after issuance of a notice to construct. If, after the date of this Agreement, modifications to the Project are required because of a change in Governmental Requirements or their interpretation by a Code Authority which had not previously been given, or which if given, was different than a prior interpretation of a Code Authority, DB shall make the required modifications to comply with the same. However, in the event of such an occurrence the compensation to DB and the associated design and pre - construction schedule may be subject to an adjustment. Nothing contained in this paragraph shall relieve DB of its obligations to modify the Project at its own expense where DB has failed to design the Project in compliance with Governmental Requirements applicable as of the date of this Agreement.

3.1.12 Obtain all permits necessary to complete the Project. City shall reimburse cost of permits, except that DB shall be responsible for obtaining and paying for all permits normally obtained by the trades or subcontractors.

3.1.13 Adhere to the provisions of all permits and rules and regulations, including but not limited to those from with the 2012 Edition of the Standard Specifications for Public Works Construction and most recent Supplement ("Greenbook") and the City of Vista.

3.1.14 Comply with all licensing requirements of the State of California and the City of Vista.

3.1.15 Use reasonable care to avoid damaging existing improvements, buildings, equipment and vegetation adjacent to the Project Site. If DB causes damage to any of this property, DB shall replace or repair said property at no expense to City and shall not be a basis for seeking an adjustment to the GMP or Contract Time.

DB agrees to indemnify City for any and all fines, penalties, liabilities, cost imposed upon City, its officers, employees and agents as a result of this Project.

3.1.16 Perform Quality Control ("QC"). Review the drawings and specifications in order to identify and correct errors and omissions and reduce the quantity of Change Orders during the course of construction. Include a detailed review of drawings and designs relative to applicable laws and standards.

3.1.17 Be fully responsible for damages, and liabilities resulting from errors or omissions below the standard of care defined in Section 3.1.19 by DB or DB's agents, employees, design consultants and contractors; such costs, damages and liabilities shall not be chargeable to the City nor shall they be a basis for seeking an adjustment in the GMP or Contract Time.

3.1.18 DB agrees to fully assume all risks, and costs associated with such risks, in performing the services and meeting the obligations under this Agreement. DB shall verify actual site conditions, topography, and facility conditions.

3.1.18.1 Unanticipated subsurface site conditions.

3.1.18.1.1 City assumes risks for unanticipated subsurface site conditions provided DB notifies City in writing within five (5) calendar days of discovery if DB believes it has
uncovered or revealed a condition which:

3.1.18.1.1.1 Differs materially form that indicated
in the geotechnical and geological reports.

3.1.18.1.1.2 Is of an unusual nature and differs
materially from conditions ordinarily
encountered and generally recognized as
inherent in the work required by this RFP and
the Design/Build Contract.

3.1.18.1.1.3 Upon receipt of a written notice, City
shall promptly investigate and if it determines
the conditions do materially differ, requiring a
change in the Work, City shall commence the
processing of a Change Order pursuant to
Section 14 of the Design/Build Contract. If
City determines there is no bona fide Work
scope change or is a minor change, which
does not impact GMP or Contract Time, City
shall notify DB within ten (10) calendar days.

3.1.18.1.1.4 DB shall not be entitled to an
adjustment in the GMP or Contract Time if DB
knew or should have known of the existence
of such conditions at the time DB submitted
and agreed to GMP or Contract Time; or the
existence of such condition could reasonably
have been discovered as a result of DB's
obligations regarding geotechnical and
geological investigations and reports as
described in the RFP.

3.1.19 DB shall perform in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions and in similar locations. Compliance with this section by DB shall not in any way excuse or limit DB's obligations to fully comply with all other terms in this Agreement.

3.1.19.1 Contractor's License. DB warrants that at least one member of the DB team shall be licensed by the California Contractor's State License Board as a Class A General Engineering Contractor. DB is to provide a list of the responsible people within their organizations performing services, O9/2J/LO25-7649, v. 2

which shall include their qualifications and their function, for approval by the City prior to start of services. City and DB shall establish "key personnel" who shall remain on the Project until Final Completion. If any such "key personnel" leave the employment of DB, City shall have the right to approve the replacement personnel assigned to this Project. DB shall comply with all licensing requirements of the State of California and City of Vista.

3.1.19.2 Project Manager and Project Design Engineer. Throughout all phases of the Project hereunder, the individual project manager, and project design engineer shall be as reflected in Exhibit 1. So Tong as the Individual Project Manager and Project Design Engineer remain in the employ of the General Contractor and/or Engineer, such persons shall not be changed or substituted from the Project, or cease to be fully committed to the Project as deemed necessary by the City in its reasonable discretion, without the prior written consent or instruction of the City.

3.1.19.3 City Right to Remove Project Manager, and Project Design Engineer. Notwithstanding the foregoing provisions of Section 3.1.19, if the Individual Project Manager or Project Design Engineer, proves not to be satisfactory to the City, upon written notice from the City to the DB, such person or person shall be promptly replaced by a person who is acceptable to the City in accordance with the procedures set forth below.

3.1.19.4 Replacement Selection of Project Manager and/or Project Design Engineer.

Section 16: Project Completion

16.1 Substantial Completion shall be that stage in the progress of the construction when all Work on the Project is sufficiently complete in accordance with the Construction Documents so that City can fully utilize entire Project; Substantial Completion shall further mean that all goods, services and systems to be provided under the terms and conditions of the Construction Documents are in place and have been initially tested, and are operationally functional, subject only to final testing, balancing and adjustments and normal Final Completion punch list Work.

16.2 Final Completion shall be deemed to occur on the last of the following events: (1) recordation of a Notice of Completion for the Project; (2) acceptance of the Project by the City; (3) issuance of a final Certificate of Occupancy for the Project; (4) submission of all documents required to be supplied by DB to City under this Agreement, including but not limited to As -Built Drawings, warranties, and operating manuals; (5) and delivery to City of a Certificate of Completion duly verified by DB.

16.3 DB shall provide City with a Certificate of Completion, certifying to City under penalty of perjury that the Project has been completed in accordance with the Construction Documents, all applicable building codes and regulations, all permits, licenses, and certificates of inspection, use and occupancy, and ordinances relating to the Project.

16.4 DB shall provide one set of City final record drawing documents at the end of construction and one copy in electronic format ("As -Built Drawings"). As -Built Drawings are to be accurate and legible records showing exact location by dimensions, and the exact depth by elevation of underground lines, valves, plugged tees, wiring and utilities.

16.5 DB shall provide a copy of, or make available before destruction, all records (which includes all writings as defined in Evidence Code Section 250) to the City upon receipt or generation, which shall include a copy of DB's filing protocol.

Section 17: Contract Time

17.1 The "Contract Time" shall be the number of calendar days stated in Section 1 for DB to achieve Substantial Completion.

17.2 "Time is of the essence" with regard to Contract Time and all milestones listed in the schedule.

17.3 The Contract Time may only be changed by a Change Order as set forth in Section 14.

17.4 Further, an extension in Contract Time will not be granted unless DB can demonstrate through an analysis of the Project Schedule that the increases in the time to perform or complete the Project, or specified part of the Project, beyond the corresponding Contract Time arise from unforeseeable causes beyond the control and without the fault or negligence of DB, its Design Consultants, and subcontractors or suppliers, and that such causes in fact lead to performance or completion of the Project, or specified part in question, beyond the corresponding Contract Time, despite DB's reasonable and diligent actions to guard against those effects.

17.5 DB carries the burden of proving an entitlement to an increase in the Contract Time.

Delays attributable to and within the control of Design Support Consultants, or subcontractor or supplier shall be deemed to be delays within the control of DB. No time extension will be allowed O9/2J/LO25-7649, v. 2

for such delays. An increase in Contract Time does not necessarily mean that DB is due an increase in the GMP.

Section 18: Late Completion

18.1 City and DB recognize that time is of the essence in this Agreement and that City will suffer financial loss if the Project is not completed within the Contract Time, plus any extensions thereof allowed in accordance with Section 17.3. They also recognize the delays, expense, and difficulties involved in proving in a legal proceeding the actual loss suffered by City if the Project is not completed on time. Accordingly, instead of requiring any such proof, City and DB agree that DB shall pay as liquidated damages (but not as a penalty) for each calendar day of delay beyond the time specified for Substantial Completion of the Project, the following amounts which DB expressly agrees are "not unreasonable under the circumstances" as defined in California Civil Code §1671(b): $1000 for each calendar day. Liquidated Damages shall not be assessed after the date on which Substantial Completion is achieved pursuant to Section 16.

Section 19: Right to Modify Work

19.1 Without invalidating the Agreement and without notice to any surety, City may at any time or from time to time, order additions, deletions, or revisions in the Project; these will be authorized by a written Change Order prepared and issued by City. Upon receipt of any such document, DB shall promptly proceed with the Work involved which will be performed under the applicable conditions of the Construction Documents (except as otherwise specifically provided).

19.2 When City desires a change in the Project, City may issue a Request for Proposal to DB.

DB will be required to respond within the time indicated by City.

Section 20: INTENTIONALLY LEFT BLANK.

Section 21: Work By Others

21.1 City may perform other work related to the Project at the Project Site by City's own forces, or let other direct contracts ("City Contractor"). The City will give DB reasonable notice of its intent to do such other work. DB's work shall take priority over the City Contractors; but the Parties will use their best efforts to coordinate their work so as to minimize the disruption to each other's work and to allow City Contractor to proceed expeditiously.

21.2 If the proper execution or results of any part of DB's work depends upon the work by the City or City Contractor, DB shall promptly inspect and report to City in writing any apparent delays, defects, or deficiencies in the City's work that render it unavailable or unsuitable for such proper execution and results. DB's failure to promptly report such delays, defects, or deficiencies in writing before commencement of the affected work, will constitute an acceptance of the City's work as fit and timely for integration with DB's Work except for latent defects and deficiencies in the City's work for which DB will not be responsible.

21.3 If DB or any person or entity working for DB causes damage to the City's or City Contractor's work, property, or person, or if any claim arising out of DB's performance of the Project by any other contractor is made against DB, by City, any other contractor, or any other person, DB shall promptly repair and/or resolve said claim at no cost to City.

Section 22: Warranties and Guarantees

22.1 DB warrants and guarantees to City that materials and equipment incorporated into the Project will be new unless otherwise specified and that all work will be in strict accordance with the Construction Documents and will not be defective. Prompt notice of defects known to City shall be given to DB. All Defective Work, whether or not in place, may be rejected, corrected, or accepted as reasonably directed by City, provided DB shall not be entitled to an extension in Contract Time or increase in GMP because of any delay or increase in cost attributable to the rejection, correction or acceptance of said work. Defective work may be rejected even if approved by prior inspection.

22.2 The warranty period shall commence when the Certificate of Substantial Completion or Notice of Completion is issued or at beneficial use by City prior to Substantial Completion or Notice of Completion, whichever occurs earlier, and extend one (1) year after that date or whatever longer period may be prescribed by laws or regulations or by the terms of any applicable special guarantee or specific provision of the Construction Documents.

22.3 INTENTIONALLY LEFT BLANK.

22.4 INTENTIONALLY LEFT BLANK.

22.5 Correction of Defective Work - If within the designated warranty period, or such longer period as may be required by laws or regulations, the Project or any part of the Project, is discovered to contain defective work, DB shall promptly, without any reimbursement or adjustment in the GMP, and in accordance with City's written instructions, either correct that defective work, or if it has been rejected by City remove it from the Project and replace it with work which is not defective. If circumstances warrant it, including but not limited to, in an emergency, City or DB may have the defective work corrected or the defective work removed and replaced. In that event, DB shall not be allowed to recover any associated costs, and DB shall reimburse City for all direct, and indirect costs of City, and City shall be entitled to an appropriate decrease in the GMP, to withhold a setoff against amount recommended for payment, or make a claim on DB's bond if DB has been paid in full.

22.6 With respect to all warranties, express or implied, from subcontractors, manufacturers, or suppliers for Work performed and materials furnished under this Agreement, the DB shall:

22.6.1 Obtain all warranties that would be given in normal commercial practice and as required by the City;

22.6.2 Require all warranties to be executed, in writing, for the benefit of City;

22.6.3 Enforce all warranties for the benefit of City, if directed by City;

22.6.4 In the event DB's warranty under Section 22.2 has expired, City may bring suit at its expense to enforce a subcontractor's, manufacturer's, or supplier's warranty;

22.6.5 DB shall assign all subcontractor, supplier and manufacturer warranties including maintenance contracts from the installer for specialized equipment to cover the limited warranty period to City at the expiration of the one year warranty.

Section 23: Use and Possession Prior to Completion

23.1 City shall have the right to take possession of or use any completed or partially completed part of the Work if mutually agreed upon by the parties. Before taking possession of or using any Work, City shall furnish DB a list of items of Work remaining to be performed or corrected on those portions of the Work that City intends to take possession of or use. However, failure of City to list any item of Work shall not relieve DB of responsibility for complying with the terms of this Agreement. City's possession or use shall not be deemed an acceptance of any Work under this Agreement, nor relieve the DB of any of its obligations under this Agreement.

23.2 While City has such possession or use, DB shall be relieved of the responsibility for the loss of or damage to the Work resulting from City's possession or use. If prior possession or use by City delays the progress of the Work or causes additional expense to DB, an equitable adjustment shall be made in the GMP or the Contract Time, and the Agreement shall be modified in writing accordingly.

Section 24: Personal Services and Non -Assignability

24.1 This is a personal services Agreement and, therefore, DB shall not alter the key employees or Design Consultants nor assign or transfer, voluntarily or involuntarily, any of its rights, duties or obligations under this Agreement except upon the prior written consent of City.

25.2 DB's obligation to indemnify under Section 25.1 shall not extend to such claims, demands, causes of action, damages, injuries, liabilities, losses and expenses, to the extent that such is the result of the active negligence or the willful misconduct of an Indemnitee. DB's obligation to defend under Section 25.1, if not covered by the insurance to be provided on the Project, shall not extend to such claims, demands, causes of action, damages, injuries, liabilities, losses and expenses, or causes of actions, to the extent that such are caused by the active negligence or the willful misconduct of the Indemnitee, and from no other cause.

Section 31: Force Majeure

31.1 Any party to this Agreement may be excused for any delay or failure to perform its duties and obligations under this Agreement, except for obligations to pay money, but only to the extent that such failure or delay is caused by an Event of Force Majeure as set forth in Section 31.2.

13.3.3: Proposed Method to Accomplish the Work
Project Understanding
GSE and N2W have a history of collaborating
with owners, operators, and stakeholders during
preconstruction to address project challenges,
mitigate risks, and develop schedules, phasing plans,
subcontracting plans, and construction documents.

GSE delivers water/wastewater treatment plant
projects across the Western United States; it is one of the areas for which the firm is recognized as experts.

GSE has delivered projects as the design -builder,
design -assist contractor, and construction manager
at risk, including subcontractor selection and trade
contracts. GSE understands that construction work
will be completed for the prices, fees, and contract
times established during RFP and ultimately GMP.

We have delivered similar design -build projects that
provide innovative solutions to complex challenges,
delivered in a fast -track environment to meet the
facility's needs.

The Raceway Basin and Buena Creek Pump Stations
require significant improvements to mitigate Fats,
Oils, and Grease (FOG) buildup and to upgrade valve
and basin infrastructure. The primary objectives of the project include:
• Implementing cost effective and efficient FOG
mitigation technologies
• Enhancing pump station performance through
strategic valve replacements
• Ensuring long-term reliability and compliance with
regulatory requirements
• Developing a Guaranteed Maximum Price (GMP)
through a collaborative transparent process
The City and District are using the progressive
design -build delivery (PDB) to complete these
projects, By using the collaborative PDB delivery
model, we will complete the scope within the
available budget, leverage prior work products,
and streamline schedule to complete the project
and minimize time under bypass conditions.

Project Approach
FOG Abatement
The PHi large volume coarse bubble diffuser was
selected as the preferred FOG abatement method for
both pump stations, N2W has extensive experience
with these systems and was the first to implement
this technology in Southern California for the
Long Beach Water Department. Typically, PHi
will design the systems for the given wetwells and
our Design -Build team will only need to purchase
and install the equipment. These systems generally
consist of an air compressor (5HP), a coarse bubble
plate installed within the wet well, and air piping
between the compressor and the plate, A controller
supplied by PHi regulates air releases into the bubble
plate. On systems with multiple plates, the controller
regulates the flow of air between each plate limiting
the required number of air compressors to one per
pump station.

As requested by the City, the design will facilitate
installation of the PHi system under a low flow
scenario at the RBPS. Our Design -Build team will
coordinate with the manufacturer and perform
site visits as necessary to confirm this method of
installation is feasible prior to ordering the proposed system, A similar investigation and coordination with
the manufacturer will be completed for the BCPS.

Although this system will likely need to be installed
while the station is under bypass, design will limit the duration of required bypass to the greatest extent
possible. This approach limits construction costs and
risk for both the City and Design -Build team. While
the station is under bypass, GSE will provide access
for EWA staff to repair a tear in the t -lock liner of the wet well,
Isolation Valves
The City would like to replace up to 24 isolation
valves within the pump station, which require
replacement due to leaking or incorrect orientation.

It is assumed that all valves are plug valves ranging
in size between 8 and 12 -inches. Based on our
experience when leaking occurs within these
valves, it is typically related to a failure of the rubber encapsulation around the plug. These failures are
usually a result of incorrect orientation resulting in
grit accumulation and subsequent rubber abrasion
when the valve is exercised, As stated in the RFP
and subsequent addenda, the City/EWA has pre -
purchased approximately 10 of these valves. The
remaining valves will need to be purchased, and
long -lead times for these valves could be the critical path for the Project. To reduce project duration, the
City could pre -purchase these replacement valves.

Alternatively, if the valve bodies are found to be in
acceptable condition, kits can purchased to replace
the internal plug and valve gearing, which will reduce
procurement time. All installed, repaired, or replaced
valves will be installed in the correct seat orientation to limit wear.

Discharge Piping
Our team will evaluate the discharge piping
configuration to determine if additional valving and
piping could be installed to allow additional pump
isolation, The pump station is set up with two wet
well sections and five pumps. Currently, only three
of the five pumps are able to be isolated due to the

POISIPOPIIOI
Section 13.3.3: Proposed Method to Accomplish the Work 5

routing of the discharge piping and connections to
the force main. Our team will evaluate the current
configuration and determine improvements that
can be made to incorporate additional functionality
and isolation ability of the pump station. All piping
improvements will facilitate isolation of individual
pumps for maintenance while allowing the remaining
pumps to stay in operation at orientation.

Bypassing Operations
The installation of replacement valves and the PHi
system at the BCPS will likely require bypassing
the entire pump station, Our team has extensive
knowledge and experience with bypassing pump
stations and treatment facilities of this capacity
and criticality. Included in our design documents
will be the proposed routing and connections for the
bypass piping system, as well as the proposed pump
units to be provided with the level of redundancy
specified. Our design will include instrumentation
used to control the bypass pumps and remote
morning of the pumping equipment. This plan will
also include the integration of these systems into
the City's SCADA system as required to provide the
appropriate level of redundancy and assurance for
operations staff. Secondary containment, emissions
controls, odor control, and noise abatement
requirements of the City, or other local jurisdictions, will be incorporated into the design documents in
concert with the City and EWA.

Overflow Basin
The RBPS overflow basin is experiencing
groundwater infiltration which has led to maintenance
and vector control issues. Our Design -Build team
will determine the best method of eliminating
groundwater infiltration, which will likely include an
under drain system to relieve hydraulic pressure from
groundwater on the exterior of the basin. Once a
suitable drainage system is installed and a dry basin
established, hydrophilic injection grouting will be
used to repair the existing cracks and joints within
the basin to ensure long-term water resistance. As
groundwater is the source of the infiltrating water,
it can be discharged to natural drainage courses
without the requirement of an Non -Pollutant
Discharge Elimination System (NPDES) permit as
long as sufficient isolation exists between the sewer
system and the drainage system.

Design & Preconstruction
Services
At GSE, partnering is our foundational philosophy.

We know that successful projects are achieved only
through a spirit of cooperation and transparency.

We are committed to upholding solid relationships
based on trust and built on performance. This is the
backbone of our approach to progressive design -
build projects. As the Design -Build team, we will use
the personnel specifically selected for this Project to leverage their expertise and practical experience to
partner with the City.

Partnering
We will approach the Project with the City's
objectives and responsibilities as the framework for
success. Within 15 days of preconstruction services
NTP, our team will meet with the City, N2W, and
stakeholders to develop a list of success factors
for the Project, within the context of a Partnering
Workshop. We will work with your staff to develop
project prioritization and an overall facility impact
prevention program for each of the Pump Stations,
Identifying these success factors provides a tool for
monitoring and measuring performance, and more
importantly, helps position the Project for long-term
success. GSE has implemented both formal and
informal partnering approaches on collaborative
delivery projects. We will collaboratively decide on
the best approach for this Project and implement an
organic plan.

Innovation
We will use preconstruction to position the Project
for success, We will leverage our team's practical
experience and capabilities to identify constructability issues, value engineering opportunities, and the
best phasing options. We will focus on opportunities
to provide design enhancements which align
with commitments made by the City, stakeholder
expectations, and construction means and methods,
Coordination
We will identify key interfaces and responsible parties while also organizing the Project into logical zones
and construction sequencing, This benefits the
communication of the two Project locations, priorities, and concerns. Given the makeup of residential,
commercial, industrial, and public properties
throughout the Project locations, project zones can
help facilitate expectations for special requirements,
commitments, and challenges in each area.

This approach fully leverages the preconstruction
phase and provides inherent benefits, including:
• Early involvement by the GSE team during
design reviews minimizes risks to public impacts,
schedule, cost, quality, and safety outcomes and
improves constructability
• The GSE team works directly with N2W to develop
solutions to challenge that affect constructability
and improves cost certainty

POISIPOPIIOI
Section 13.3.3: Proposed Method to Accomplish the Work 6

• Overall Project risk is minimized as construction
sequencing, schedule, and safety approaches,
including complex utility relocations and
protections, are developed early in the process
Cost Estimating Methodology
Over the last decade, GSE has developed and
refined a template for conceptually estimating
similar projects that Juan Catano, GSE's Project
Estimator, will use to produce iterative cost models as developed for this proposal, and ultimately the GMP,
Our basis for many of these models is our cost
history of self -performing similar activities within
the scope defined for the Project.

Additionally, GSE anticipates incorporating
subcontractors and suppliers early in the preliminary
design process for accurate pricing on scopes
of work that vary from project to project, These
include equipment procurement packages, specialty
trade contractor packages, electrical systems,
and piping suppliers. We recommend using these
same subcontractor and supplier team members
in a design -assist capacity throughout the course
of design progression to eliminate scope gap and
leverage each firm's expertise.

GSE has an open book estimating philosophy
to provide transparency throughout the entire
pricing process on our current Collaborative
Design -Build project with Cal Polytechnic
University San Luis Obispo, and we will use the
same approach on this Project. Not only does this
establish a sense of partnering while developing
and negotiating the GMP, but it also brings attention
to large scopes of work that may need re -design
or value engineering. Open book estimating will
allow the team to address cost issues quickly while
reducing estimate review duration.

Procurement Strategy
Lingering supply chain and industry capacity issues
make the procurement process a critical focus for this
Project. This requires an early and sustained focus
on equipment and materials selection, submittals,
and procurement. The area of greatest concern is the
process equipment, instrumentation, and any early
scopes of work. This is one of the key risks to the
project schedule and requires that all parties focus on procurement from the start.

Subcontracting
We will leverage subcontractor expertise during
preconstruction and maximize bid participation
during construction with the most qualified
subcontractors available through:
• Outreach: GSE's project leadership reaches
out to subcontractors early in preconstruction.

Our managers, engineers, and superintendents
personally contact quality subcontractors to
promote the Project and obtain early commitments
to bid, We also work with lower tier and S/
DBE subcontractors, GSE will advertise in local
publications, use web -based services, and
independently contact our robust network of
preferred subcontractors to ensure appropriate
bidding coverage.
• Bid Packages: We prepare well-defined bid
packages that align with the skill set of the local
subcontracting community. We define expectations
for responsiveness, provide clear and detailed
information on schedule, and clearly state risk
expectations through the published bid packages.
• Determination of Bidder Eligibility: We use a
verification process to determine subcontractor
eligibility for key scopes, ensuring that they have
adequate capacity and technical expertise for the
Project, We will determine the eligibility criteria in
collaboration with the City.

GSE's approach to subcontracting addresses the
following risks associated with subcontracting work:
• Scope Gap: Making sure that all work is allocated
to either the Design -Build team or a subcontractor
• Schedule: Overlapping schedules for different
subcontractors can result in inefficiencies
• Quality: Making sure subcontractors understand
quality requirements and that work must be built to
meet the requirement of this job.

Validation of Self -Perform Costs
To ensure self -perform costs are fair and competitive, our team will follow a structured validation process.

This includes benchmarking labor, equipment,
and material costs against industry standards
and historical data from similar projects. We will
conduct a detailed cost breakdown analysis,
incorporating unit pricing, productivity rates, and
overhead allocations. Additionally, third -party
cost estimators or independent audits may be
used to cross-check accuracy (at the City's cost).

Transparent documentation of assumptions,
subcontractor comparisons, and contingency factors
will be provided to ensure accountability. Regular
reviews and open book collaboration with project
stakeholders will further validate self -perform
cost structures, ensuring alignment with budget

POISIPOPIIOI
Section 13.3.3: Proposed Method to Accomplish the Work 7

expectations and cost efficiency.

Construction Services
After achieving an accepted and best value GMP,
GSE will seamlessly transfer our preconstruction
team to construction execution. We will manage
the critical elements of the Project, including the
procurement of long -lead elements in the valves
and PHi System, coordination with essential
subcontractors like the bypass sub, and resource
allocation for self -perform work scopes.

We focus on safety while maintaining budget and
schedule. Project Manager Steven Villanueva will
manage all elements of the Project, including the
flow of information from office to field. Steven will
hold weekly internal coordination meetings with key
staff, including Superintendent Jeff Burnach, to review process and progress. The goal of these meetings is
to ensure quality is met, procurements are on track,
safety goals are achieved with GSE crews as well
as subcontractors, and to prepare three-week look -
ahead schedules.

Once our team has ensured we are meeting internal
expectations for the Project, we will report on Project status to the City through a formal status report. GSE
expects to hold weekly meetings with the City and
project stakeholders. Similar to the preconstruction
phase, we will focus on collaboration during each
meeting. We will begin weekly meetings with a report
of overall schedule status, along with a detailed three- week look -ahead schedule review. Following the
schedule review, GSE and the City's staff will conduct
a review of the budget status and procurement
progress. A review of submittals, RFIs, and new and
old business follows, concluding with a status report
from any stakeholders on concerns or comments.

Operations and Start -Up
Start -Up and Performance Testing (SPT) will be
led by Commissioning Manager Jeff Burnach,
who has commissioned dozens of similar facilities,
Jeff will be supported by Project Manager Steven
Villanueva, along with representatives from selected
specialty suppliers. We will require (as a condition
of the purchase contract) all vendors to provide
representation during start-up and to provide training
of the contract operator personnel on the proper use
and maintenance of the facilities. Start-up services
will be required for all items where periodic or routine maintenance or special training is required.

Jeff will schedule, coordinate and manage the various
manufacturer representatives who will be part of
the SPT program through the steps of equipment
checkout, loop testing, start-up, and finally,
Performance Testing.

Key components of the SPT include:
• PHi Bubbler System
• PHi Air Compressor and Controller
• New Valving
• New Slide Gate
Commissioning
Commissioning is the final step in the culmination
of SPT and will require hands-on involvement
from City staff, Encina Wastewater Authority, and
representatives. Jeff will coordinate training that
will be conducted at the convenience of the facility
operators and only after the key staff and Jeff have
reviewed the approved O&M manuals and have had
the opportunity to develop questions related to the
training. O&M materials include engineer -verified
as -built drawings and specifications, commissioning
documentation, Building and Facilities Manuals,
Mechanical Equipment Manuals, and Training Plans.

Once the staff is fully trained and equipment is
started up and tested in conjunction with appropriate
agency approvals, operator staff will bring the new
facilities online with the support of GSE and N2W.

Previous Work Product
We will leverage findings and recommendations from:
• FOG Mitigation Recommendation Technical
Memorandum (2021) - Evaluating and selecting
FOG mitigation technologies based on cost -benefit
analysis

In May 2022, GSE Construction partnered with World Water Works (equipment supplier) and Ardurra on a design -build project to pro vide the owner with a turnkey 1 MGD wastewater pretreatment system to replace and upgrade the capacity of the existing wastewater pretreatment plant onsite. The main objectives were to provide increase d treatment capacity for a re cent beverage plant expansion, while also producing higher quality effluent wastewater to be sent to the POTW with the design and construction to be complete in a 2 -year window.

The primary goals of the project were to provide a low maintenance and operator friendly system capable of flow equalization, neutralization of pH swings and a reduction of TSS, FOG, BOD & CO D. Additionally, the design considered the owners plans for future wastewater reuse or groundwater injection options and provided the ability for easy expansion. The design -build scope included full system engineerin g, permitting, construction, and startup of the treatment plant.

Construction included underground utilities (plant influent line, plant e ffluent lin e, manholes, flume, potable wate r, fire line, fiber optic, utility po wer), concrete foundation s, six bo lted steel tanks (Calamity, EQ Anoxic, 2xM BBRs and Sludge), pre-engineered metal building, DAF, disk filter, solids handling/removal, lift stations, misc. metals, above ground SST & PVC piping, building HVAC & fire suppressio n, chemical tan ks/piping and electrical systems.

Throughout the process, GSE provided guidance on constructability of all systems and was integral in specifying all materials of construction. The design - build tea m has assisted the owner in overc oming multiple projec t issues, including the re -design and re -permitting of the existing stormwate r system to allow for plant construction in an existing pond, permitting and construction of the utility power feed to the WW TP, design and construction of added building fire suppression systems and construction and integration of the WWTP into the beverage plant fiber optic network.

The WWTP is complete an d operational as of May 2024.

Design -Build WWTP MBBR Improvements RP -1 Headworks & B ar Screens System Improvem ents I Ontari o, CA
The project encompassed a c omprehensive upgrade and enhancement of the existing headworks bar screen system at the RP -1 Wastewater Treatment Facility.

The primary objective was to modernize the facility's screening capabilities by replacing aging and inefficient equipment with advanced, high-performance bar screen technology. This initiative was undertaken to improve the facility's ability to effectively remove debris and solids from incoming wastewater flows, thereby enhancing overall plant efficiency, reliability, and compliance with regulatory standards .

The scope of work included the systematic removal and replacement of outdated bar scree n units, followed by the installation of screening systems designed to optimize flow management and reduce operational bottlenecks, Additionally, the project involved significant upgrades to the mechanical, electrical, and control systems, ensuring seamless integration a nd enhanced automati on of the screening process. These improvements were tailored to pr ovide increased capacity, greater durability, and long-term operational resilience.

Beyond the equipment upgrades, the project required structural modifications to the screening chamber and surrounding infrastructure to accommodate the ne wly installed systems. This included reinforcing existing structures, modifying channels for improved hydraulics, and implementing measures to enhance worker access and maintenance efficie ncy,
By implementing these upgrades, the RP -1 Wastewater Treatment Facility significantly improved its ability to manage influent screening, reduce maintenance demands, and extend the lifespan of critical infrastructure. The modernization efforts also contributed to greater regulatory compliance, enviro nmental prote ctio n, and the overall sustainability of the facility's operations.

Meyer Ranch WWTP E xpansion
New Branfels, TX
GSE Construction partnered with Cloacina LLC, a packaged MBR supplier, to deliver a turnkey MBR solution that addressed the owner's expansion needs. The existing MBR system on -site was provided by another vendor, and the expansion design was based on adding more MBR units to match the existing system. GSE and Cloacina offered an alternative packaged MBR system at a lower cost, using higher -quality materials, and were ultimately selected by the owner.

Although the project initially followed a design -bid -build approach, the alternative MBR system required a complete red esign . Our team redesigned foundations and underground utilities to accommodate the new system and replaced the extensive sludge handling system with a more compact, efficient dewatering system, providing value engineering savings to the owner, Throughout the redesign process, GSE provided constructability guidance and was instrumental in specifying all materials of construction. We also advised the owner and design engineer on the pr oper installation of piping, valves, and chemical systems, ensuring a higher -quality final product at no additional cost .

Additionally, our team designed an effluent flume system to meet the county's additional requirements.
