O Agenda Item: 5 CITY OF SANTA CLARITA .` AGENDA REPORT CONSENT CALENDAR CITY MANAGER APPROVAL: DATE: September 23, 2025 SUBJECT: TRANSIT HYDROGEN FUELING INFRASTRUCTURE CONTRACT FOR SPECIAL INSPECTIONS AND MATERIALS TESTING SERVICES DEPARTMENT: Economic Development PRESENTER: Adrian Aguilar RECOMMENDED ACTION City Council: Award a professional services contract in the amount of $358,816 to Twining, Inc., to provide special inspections and material testing services, and authorize a 15 percent contingency in the amount of $53,822, for a total contract not to exceed $412,638. 2. Authorize the City Manager or designee to execute all contracts and associated documents, subject to City Attorney approval. BACKGROUND In December 2018, the California Air Resources Board adopted the Innovative Clean Transit (ICT) regulation. The ICT regulation requires all public transit agencies to gradually transition to 100-percent zero -emission bus fleets. To prepare for this transition, staff analyzed various options and determined that hydrogen fuel cell electric buses were the best option available to meet the City of Santa Clarita's (City) needs. This determination was based on range, need for additional infrastructure, and long-term operating costs. In March 2023, the City retained Trillium Inc. to design and construct a hydrogen production and fueling station at the Transit Maintenance Facility (TMF). The TMF hydrogen project is designed to construct a station that supports up to 16 hydrogen fuel cell electric buses, and includes the flexibility to expand in the future with additional storage capacity and a second hydrogen producing unit without requiring significant design modifications. Construction is currently underway and is expected to be completed in January 2026. Page 1 Packet Pg. 73 O In support of the project, the City conducted a Request for Proposals (RFP) to solicit proposals from qualified firms to provide special inspections and material testing services during construction of the station. The RFP was published and circulated via the City's e-procurement system, BidNet, on July 25, 2025. The City transmitted the solicitation to 3,576 vendors on BidNet, of which 69 vendors downloaded the RFP. A total of two companies provided proposals for consideration. These proposals were reviewed and evaluated based on each company's ability to meet the specific needs of the City. An evaluation panel, comprised of staff from the Transit division and the City's contracted hydrogen consulting team, scored the responses based on a 100-point scale using the following categories of weighted criteria: • Past Experience (50 points) • Technical Approach (30 points) • Responsiveness to the RFP including content, format, and thoroughness of the written proposal (20 points) In reviewing the proposals, the evaluation panel awarded the highest score to Twining, Inc., and determined their proposal offered the best overall value to meet the special inspections and material testing services needs. The results of the evaluation and interviews are outlined below: Rank Company Location Score 1 Twining, Inc. Ventura, CA 87 2 Certerra RMA Group Carson, CA 83 Twining, Inc., demonstrated an in-depth understanding of the project needs and provided a detailed scope of work and approach to the project. Based on its experience with other projects, and the completeness of their proposal for this project, staff recommends awarding the special inspections and material testing services contract to Twining, Inc. The proposal is available in the City Clerk's Reading File. The requested contingency will cover the cost of unforeseen testing requirements, additional field inspections, and any additional lab work requested by the City. ALTERNATIVE ACTION Other action as determined by the City Council. FISCAL IMPACT The total cost of this project, including contingency, is $412,638 and does not impact the General Fund. Federal Transit Administration grant funds are available to cover 100 percent of the cost. Adequate funds from Transit Fund (700) have previously been appropriated as part of the Fiscal Year 2025-26 budget in project expenditure account F1026700-516101 to support the recommended contract.

Twining I City of Santa Clarita - Hydrogen Fueling Station 11 1.1 RESPONSE FILE: SECTION 1.1.3.: SCOPE OF WORK DESIGN -RELATED GEOTECHNICAL ENGINEERING WORK PLAN When the need for geotechnical design -related services arises at the the City, we will provide the City with a detailed proposal for execution of the specific project requirements. Based on our under- standing of the potential projects, we anticipate the need for the following general scope of services that are related to design support (i.e., geotechnical site investigations). Task 1 - Review Background Information Task 2 - Coordinate and Perform Field Exploration Task 3 - Perform Geotechnical Laboratory Testing Task 4 - Perform Engineering and Geologic Analy- ses Task 5 - Prepare a Geotechnical Report The remainder of this section provides a descrip- tion of each of the above tasks and our approach to complete the tasks. Task 1 - Review Background Information Twining reviews available geotechnical investigation reports and any other geotechnical information prepared for the site and provided to us by you, if available. We will also review historic aerial photography and topographic maps as well as available published and unpublished geologic literature contained in our files, including publications prepared by the California Geological Survey and the United States Geological Survey. This task will help evaluate the existing site conditions so that the field exploration program can be most efficiently executed while obtaining the necessary data to provide specific geology and geotechnical engineering recommendations. Task 2 - Coordinate and Perform Field Exploration Before starting our exploration program, Twin- ing conducts a field reconnaissance to mark the locations of our planned subsurface explorations. We meet with the City to review the locations in the field to help mitigate the potential to encounter buried objects or utilities. As required by law, we will notify Underground Service Alert (USA) of the proposed subsurface exploration locations at least 48 hours prior to drilling so that conflicts between the proposed locations and publicly -owned under- ground utilities can be identified. As directed by the City, we will also utilize Geovision to further verify utility locations. Our field exploration may consist of truck -mounted drilling, hand augering, machine- or hand -excavated test pits, or a combination of these efforts depending on specific project requirements. Additionally, we can provide Ground Penetrating Radar (GPR) and Cone Penetration Testing (CPT) as needed. The field exploration programs will be supervised by a Twining engineer or geologist who will log the surface and subsurface conditions encountered and obtain driven and bulk samples for laboratory observation and testing. Drive samples are typically collected at approximately 5-foot intervals within the borings using either a Standard Penetration Test (SPT) sampler or a California Modified sampler. Twining conducts drilling and sampling in general accordance with applicable American Society of Testing and Materials (ASTM) standards. At the completion of the drilling, we will transport the soil samples to our laboratory. Immediately upon completion of drilling and sampling, the borings will be backfilled with soil cuttings derived from the borings or backfill may be performed using grout and/or bentonite chips as needed. Upon completion of the exploration, the locations will be patched and repaired so that the original site conditions are restored to the the City's satisfaction. Surface mapping in hillside areas will be performed by a Twining geologist, recording the types of surficial materials exposed at the site, the locations of contacts among different material types, the attitudes of bedrock features such as bedding and foliation, and the presence and character of discontinuities such as faults, joints, or slip surfaces. Where exploration is necessary within designated Earthquake Fault Zones, fault trenching or other appropriate exploration will be performed in accordance with the provisions of Division 2, Chapter 7.5 of the Public Resources Code and the City regulations. Where active faults are identified, appropriate setbacks from the fault traces will be recommended. With the implementation of stormwater requirements on most projects in Southern California, Twining can perform percolation tests for the purpose of estimating the infiltration rate of the on -site soils, if needed. Percolation testing is performed in general accordance with the appropriate local procedures. If such services are needed, Twining will work together with the project civil engineer to ensure these needs are met and the best system of containing stormwater on the site is implemented. Twining I City of Santa Clarita - Hydrogen Fueling Station 12 1.1 RESPONSE FILE: SECTION 1.1.3.: SCOPE OF WORK Task 3 - Perform Geotechnical Laboratory Testing Samples obtained from the exploratory borings are transported to Twining for observation and testing. Laboratory tests are performed on selected samples obtained from the borings to aid in the classification and to evaluate the engineering properties of the subsurface soils. Typically, the laboratory tests include some or all of the following, depending on project needs: » Moisture and density » Soil classification testing including #200 wash sieve and Atterberg limits » Direct shear » Consolidation » Expansion index » R-Value and CBR » Corrosivity & Permeability » Maximum dry density -optimum moisture content The exact quantities and types of tests depend on the material types encountered during our subsurface exploration and the specific project requirements. Task 4 - Conduct Engineering Analyses The results of our field exploration and geotechnical laboratory tests are evaluated and engineering analyses are performed in order to provide geotechnical recommendations for the design and construction of the proposed project. Typically, the following engineering analyses are performed in support of geotechnical design - related projects: » Evaluation of general subsurface conditions and description of types, distribution, and engineering characteristics of subsurface materials at the site » Evaluation of geologic hazards, including site seismicity, liquefaction and seismic settlement potential, and preliminary recommendations for appropriate mitigation measures, if necessary » Evaluation of historic earthquakes in the region with magnitudes and distance from the site to the epicenter » Evaluation of current and historical groundwater conditions at the site and potential impact on design and construction » Evaluation of the seismic design parameters in accordance with the California Building Code for use in structural design » Evaluation of surficial and deep-seated slope stability » Evaluation of the feasibility of using on -site soils for foundation and fill support » Development of general recommendations for earthwork, including site preparation and excavation requirements, requirements for placement of compacted fill, and site drainage » Recommendations for suitable building foundation systems, retaining wall foundations, and provision of allowable bearing capacities, associated settlement estimates, and lateral pressures and resistances » Recommendations for appropriate infiltration rates for on -site soils for use by the civil engineer in the design of on -site stormwater storage systems » Evaluation of expansion potential and, if needed, recommendations to mitigate the potential impact of expansive soil conditions on the proposed project » Recommendations for vehicular pavement sections including rigid and flexible sections » Evaluation of the corrosion potential of the on -site earth materials Task 5 - Prepare Geotechnical Report After the laboratory testing and engineering analyses are complete, a report is prepared to summarize the data collected and present our findings, conclusions, and geotechnical recommendations for the design and construction of the proposed project. We will provide preliminary geotechnical data and recommendations within 10 calendar days of completion of the field, and we will provide a final report within 15 working days of completion of the field work. The report includes the following: » Site location map » Project Information » Boring location map and logs of borings that include summarized laboratory testing results using the computer program gINT » Soil classification of the soil materials encountered in accordance with the Unified Soil Classification System » Seismic Evaluation summary with Seismic Zone Coefficients and Soil Profile per CBC 2010 requirements » Review/summary of field and laboratory test procedures and data » Geotechnical recommendations for the design and construction of foundations and grading » Statement of future site performance in accordance with the provisions of Section 111 of the the City of Los Angeles Building Code All services are performed in accordance with the applicable federal, state, and the City requirements. Twining provides five copies of the report wet signed and sealed by a licensed geotechnical engineer. Preparation of Report for Submittal to the Project Team: We strive to prepare reports that are clear and concise. As needed, we present the the City with a draft version of our completed report for review and comment by the project team so that recommendations can be "fine- tuned" if needed.

CONSULTANT shall place in its subconsulting agreements and cause its subconsultants to agree to indemnities and insurance obligations in favor of CITY and other Indemnitees in the exact form and substance of those contained in this Agreement. 4. INSURANCE a. Before commencing performance under this Agreement, and at all other times this Agreement is effective, CONSULTANT will procure and maintain the following types of insurance with coverage limits complying, at a minimum, with the limits set forth below: Type of Insurance Commercial general liability: Professional liability Business automobile liability Workers compensation Limits $1,000,000 $1,000,000 $1,000,000 Statutory requirement b. Commercial general liability insurance will meet or exceed the requirements of ISO-CGL Form No. CG 00 011185 or 88. The amount of insurance set forth above will be a combined single limit per occurrence for bodily injury, personal injury, and property damage for the policy coverage. Automobile coverage will be written on ISO Business Auto Coverage Form CA 00 0106 92, including symbol 1 (Any Auto). Liability policies will be endorsed to name CITY, its officials, and employees as "additional insureds" under said insurance coverage and to state that such insurance will be deemed "primary" such that any other insurance that may be carried by CITY will be excess thereto. Such endorsement must be reflected on ISO Twining I City of Santa Clarita - Hydrogen Fueling Station 40 ATTACHMENTS: REQUIRED FORMS Form 1 - Notice to Proposers Regarding Contractual Requirements Form No. CG 20 10 1185 or 88, or equivalent. Such insurance will be on an "occurrence," not a "claims made," basis and will not be cancelable or subject to reduction except upon thirty (30) days prior written notice to CITY. c. Professional liability coverage will be on an "occurrence basis" if such coverage is available, or on a "claims made" basis if not available. When coverage is provided on a "claims made basis," CONSULTANT will continue to renew the insurance for a period of at least three (3) years after this Agreement expires or is terminated. Such insurance will have the same coverage and limits as the policy that was in effect during the term of this Agreement, and will cover CONSULTANT for all claims made by CITY arising out of any errors or omissions of CONSULTANT, or its officers, employees or agents during the time this Agreement was in effect. d. CONSULTANT will furnish to CITY duly authenticated Certificates of Insurance evidencing maintenance of the insurance required under this Agreement, including endorsements, and such other evidence of insurance or copies of policies as may be reasonably required by CITY from time to time. Insurance must be placed with California -admitted insurers with (other than workers compensation) a current A.M. Best Company Rating of at least "A:VII." e. Waiver of Subrogation: The insurer(s) agree to waive all rights of subrogation against CITY, its elected or appointed officers, officials, agents, volunteers and employees for losses paid under the terms of the workers compensation policy which arise from work performed by CONSULTANT for CITY. f. Should CONSULTANT, for any reason, fail to obtain and maintain the insurance required by this Agreement, CITY may obtain such coverage at CONSULTANT's expense and deduct the cost of such insurance from payments due to CONSULTANT under this Agreement or terminate pursuant to TERMINATION section. In the alternative, should CONSULTANT fail to meet any of the insurance requirements under this Agreement, City may terminate this Agreement immediately with no penalty. g. Should CONSULTANT'S insurance required by this Agreement be cancelled at any point prior to expiration of the policy, CONSULTANT must notify City within 24 hours of receipt of notice of cancellation. Furthermore, CONSULTANT must obtain replacement coverage that meets all contractual requirements within 10 days of the prior insurer's issuance of notice of cancellation. CONSULTANT must ensure that there is no lapse in coverage. h. The CITY shall be entitled to any coverage in excess of the minimums required herein. I have read and understand the above requirements and agree to be bound by them for any work performed for the City.

The amount of insurance set forth above will be a combined single limit per occurrence for bodily injury, personal injury, and property damage for the policy coverage. Automobile coverage will be written on ISO Business Auto Coverage Form CA 00 0106 92, including symbol 1 (Any Auto). Liability policies will be endorsed to name CITY, its officials, and employees as "additional insureds" under said insurance coverage and to state that such insurance will be deemed "primary" such that any other insurance that may be carried by CITY will be excess thereto. Such endorsement must be reflected on ISO Twining I City of Santa Clarita - Hydrogen Fueling Station 40 ATTACHMENTS: REQUIRED FORMS Form 1 - Notice to Proposers Regarding Contractual Requirements Form No. CG 20 10 1185 or 88, or equivalent.

Professional liability coverage will be on an "occurrence basis" if such coverage is available, or on a "claims made" basis if not available. When coverage is provided on a "claims made basis," CONSULTANT will continue to renew the insurance for a period of at least three (3) years after this Agreement expires or is terminated. Such insurance will have the same coverage and limits as the policy that was in effect during the term of this Agreement, and will cover CONSULTANT for all claims made by CITY arising out of any errors or omissions of CONSULTANT, or its officers, employees or agents during the time this Agreement was in effect. d.

Should CONSULTANT, for any reason, fail to obtain and maintain the insurance required by this Agreement, CITY may obtain such coverage at CONSULTANT's expense and deduct the cost of such insurance from payments due to CONSULTANT under this Agreement or terminate pursuant to TERMINATION section. In the alternative, should CONSULTANT fail to meet any of the insurance requirements under this Agreement, City may terminate this Agreement immediately with no penalty. g. Should CONSULTANT'S insurance required by this Agreement be cancelled at any point prior to expiration of the policy, CONSULTANT must notify City within 24 hours of receipt of notice of cancellation. Furthermore, CONSULTANT must obtain replacement coverage that meets all contractual requirements within 10 days of the prior insurer's issuance of notice of cancellation. CONSULTANT must ensure that there is no lapse in coverage. h. The CITY shall be entitled to any coverage in excess of the minimums required herein.
