Type of Inspection / Service: Soil­Cement Coring
Date: 12/15/2020
I arrived on site as requested by Casey Kirk, PSOMAS construction manager, to observe the coring in previously placed soilcement at Area 15. Boring was conducted by Keller and logged by Lindsay Shapiro and Blair Rushing, Keller's engineer.

Keller used a Soilmec SM­10 micro drilling rig with 3 inch diameter drilling rods to drill a total of 2 locations at Cell 15­6.

Drilling operation lasted approximately 2 hours to reach the final depth. Two coring operation was conducted at Cell 15­6.

Boring 15­6A and 15­6B was drilled to a depth of 10 feet and 24 feet below grade surface (bgs), respectively.  Two borings were conducted because 15­6A was located near to the side of the cell.  The offset to the new location 15­6B, placed the rig closer to the center of the cell.  Observed core recovery from each run ranged from mid 93 to 100 percentile. Rock quality designation (RQD) ranged from a low of 83 to 99 percent. Note, core recovery and RQD was calculated by Keller. The final boring depth at Area 15, boring 15­6B was approximately 23 to 24 feet bgs.

At approximately 20 feet bgs at Area 15, Cell 15­6B, a layer of clayey sand was observed. Keller crew continued drilling pass this depth and ended the operation at approximately 23 to 24 feet bgs. Soil in the lower depth, as observed from the core sample, was a well­graded sand layer that was approximately 16 to 18 inch thick, followed by a 12 to 14 inch layer of clay.  All cores were stored in cardboard boxes.

A total of 3 samples were collected from the boring site at various depths. Samples were collected from 2.5 feet bgs, 10 feet bgs, and 15 feet bgs. All samples were transported to BSK Livermore Lab for storage and curing.

THIS AGREEMENT is made and entered into as of the _____ day of __________________, 2022 by and between the City of Brentwood, a municipal corporation of the State of California ("City"), and Construction Testing Services, Inc., a C Corporation ("Consultant") (each a “Party” and collectively, the “Parties”).

RECITALS
A. City requires the professional services of a consultant specifically trained and experienced in geotechnical/construction materials testing services, which are professional services outside of services offered by City.

B. Consultant has the professional skills and experience necessary to perform the services described in this Agreement.

C. Consultant customarily engages in these services as part of its independently established trade, occupation, and/or business, separately from its work for City.

D. City desires to engage Consultant to provide these services by reason of its qualifications and experience in performing such services
E. Consultant has submitted a proposal to City and has affirmed its willingness and ability to perform such work on the terms and manner set forth in this Agreement.

NOW, THEREFORE, in consideration of these recitals and the mutual covenants contained herein, the Parties agree as follows:

1. Scope of Work.

1.1 City retains Consultant, as an independent contractor, to perform, and Consultant agrees to render, those services (the "Services") that are described in the attached Exhibit "A," which is incorporated by this reference, pursuant to this Agreement’s terms and conditions.

1.2 Consultant will control the manner and the means of the work to be performed, and be responsible for the professional quality, technical accuracy and coordination of the Services. Consultant will, without additional compensation, correct or revise any errors or deficiencies in the Services.

1.3. Consultant will keep City informed on a regular basis that the Services are being performed in accordance with the requirement and intentions of this Agreement.

1.4 If applicable, Consultant has designated those persons listed in Exhibit “A” to provide the Services to the City. Consultant will not change or reassign those persons described in Exhibit “A” without prior written notice to City, and will not replace those individuals with individuals to whom City has a reasonable objection.

2. Standard of Performance. Consultant acknowledges that in entering into this Agreement the City is relying on Consultant's special skills and experience to do and perform the Services. While performing the Services, Consultant will exercise the reasonable professional care and skill customarily exercised by reputable members of Consultant's profession practicing in the Northern California area. The acceptance of the Services by City does not release Consultant from these obligations.

Consultant will be responsible for employing or engaging all persons necessary to perform the Services.

Consultant will control the manner and means of the services to be performed by its employees and subconsultants. All of Consultant's staff will be qualified by training and experience to perform their DocuSign Envelope ID: FCFC00B2-D385-476C-B135-220A5E783022 C.4.g
Packet Pg. 276 Attachment: Construction Testing Services, Inc. Geotechnical Agreement (2677 : Approval of On-Call Civil/Structural, Geotechnical & Survey 2 PSA_City Attorney Approved Version 040821
assigned tasks. Consultant will give its personal attention to the fulfillment of the provisions of this Agreement by all of its employees and subcontractors, if any, and will keep the Services under its control.

On demand of City, if any employee or subcontractor of Consultant fails or refuses to carry out the provisions of this Agreement or appears to be incompetent or to act in a disorderly or improper manner, he or she will be discharged immediately from the Services.

3. Term. Unless earlier terminated, the term of this Agreement will be effective for a period of one year from the date first above written. The City Manager may amend the Agreement to extend it for two additional one-year periods or parts thereof in an amount not to exceed one hundred thousand dollars ($100,000) per Agreement year. Extensions will be based upon a satisfactory review of Consultant's performance, City needs, and appropriation of funds by the City Council. The parties will prepare a written amendment indicating the effective date and length of the extended Agreement.

4. Schedule. Consultant will generally adhere to the schedule set forth in Exhibit “A” provided, that City will grant reasonable extensions of time for the performance of the Services occasioned by unusually lengthy governmental reviews of Consultant’s work product or other unavoidable delays occasioned by unforeseen circumstances; provided, further, that such unavoidable delay will not include strikes, lockouts, work stoppages, or other labor disturbances conducted by, or on behalf of, Consultant’s officers or employees.

Consultant acknowledges the importance to City of City’s project schedule and agrees to put forth its best professional efforts to perform the Services in a manner consistent with that schedule. City understands, however, that Consultant’s performance must be governed by sound practices. Consultant will work such overtime or engage such personnel and equipment as necessary to maintain the schedule, without additional compensation.

5. Compensation.

5.1 The total fee payable for the Services to be performed during the term of this Agreement will be a not to exceed amount of one hundred thousand dollars ($100,000) as may be further specified in the attached Exhibit “A.” No other compensation for the Services will be allowed except for items covered by subsequent amendments to this Agreement. The City reserves the right to withhold a ten percent (10%) retention until City has accepted the Services.

5.2 Payment will occur only after receipt by City of invoices sufficiently detailed to include hours performed, hourly rates, and related activities and costs for approval by City.

5.3 Within thirty (30) days after receipt of any applicable progress payment request, City will verify the accuracy of the request, correct the charges where appropriate, and make payment to Consultant in an amount equal to the amount of such application, as verified or corrected by City. No payment made prior to completion and acceptance of the Services will constitute acceptance of any part of the Services.

City reserves the right to withhold payment from Consultant on account of Services not performed satisfactorily, delays in Consultant's performance of Services, or other defaults hereunder.

6. Status of Consultant. Consultant will perform the Services as an independent contractor, free from the control and direction of City, in pursuit of Consultant’s independent calling, and not as an employee of City. The persons used by Consultant to provide the Services under this Agreement will not be considered employees of City for any purposes whatsoever and City will not pay any tax, workers’ compensation insurance, retirement contributions or unemployment contributions on behalf of Consultant or its employees or subcontractors. Consultant agrees to indemnify and pay City within thirty (30) days for any tax, retirement contribution, social security, overtime payment, unemployment payment or workers’ compensation payment, including, but not limited to, those based on any provision of the Federal Affordable Care Act, which City may be required to make on behalf of Consultant or any agent, employee, or contractor of Consultant for work done under this Agreement. The payment made to Consultant pursuant to the Agreement will be the full and complete compensation to which Consultant is entitled. City will not make any federal or state tax withholdings on behalf of Consultant or its agents, employees or subcontractors.

Packet Pg. 277 Attachment: Construction Testing Services, Inc. Geotechnical Agreement (2677 : Approval of On-Call Civil/Structural, Geotechnical & Survey 3 PSA_City Attorney Approved Version 040821
At the City’s election, City may deduct the amounts paid pursuant to this Section, from any balance owing to Consultant.

7. Subcontracting. Consultant's services are being requested by City because they are unique and personal. Except as may be specified in Exhibit “A”, Consultant will not subcontract any portion of the Services without prior written approval of City Manager or his/her designee. If Consultant subcontracts any of the Services, Consultant will be fully responsible to City for the acts, errors and omissions of Consultant's subcontractor and of the persons either directly or indirectly employed by the subcontractor, as Consultant is for the acts and omissions of persons directly employed by Consultant. Nothing contained in this Agreement will create any contractual relationship between any subcontractor of Consultant and City.

Consultant will be responsible for payment of subcontractors. Consultant will bind every subcontractor and every subcontractor of a subcontractor by the terms of this Agreement applicable to Consultant's work unless specifically noted to the contrary in the subcontract and approved in writing by City.

8. Other Consultants. The City reserves the right to employ other consultants in connection with the Services.

9. Indemnification. Consultant agrees to indemnify, including the cost to defend, City, its officers, agents, volunteers and employees from any and all claims, demands, costs or liability that arise out of, or pertain to, or relate to the negligence, recklessness, or willful misconduct of Consultant and its agents in the performance of services under this Agreement, but this indemnity does not apply to liability for damages for death or bodily injury to persons, injury to property, or other loss, arising from the sole negligence, willful misconduct or defects in design by City or the agents, servants, or independent contractors who are directly responsible to City, or arising from the active negligence of City.

10. Insurance. Consultant will obtain and maintain, at its cost and expense, for the duration of the Agreement and any and all amendments, insurance against claims for injuries to persons or damage to property which may arise out of or in connection with performance of the Services by Consultant or Consultant’s agents, representatives, employees or subcontractors. The insurance will be obtained from an insurance carrier admitted and authorized to do business in the State of California. The insurance carrier is required to have a current Best's Key Rating of not less than "A:VII."

10.1 Coverages and Limits. Consultant will maintain the types of coverages and minimum limits indicated below, unless Risk Manager or City Manager, in consultation with the City Attorney approves a lower amount. These minimum amounts of coverage will not constitute any limitations or cap on Consultant's indemnification obligations under this Agreement. City, its officers, agents, volunteers and employees make no representation that the limits of the insurance specified to be carried by Consultant pursuant to this Agreement are adequate to protect Consultant. The coverage will contain no special limitations on the scope of its protection to the above-designated insureds except for Workers Compensation and errors and omissions insurance. Consultant will obtain occurrence coverage, excluding Professional Liability, which will be written as claims-made coverage. If Consultant believes that any required insurance coverage is inadequate, Consultant will obtain such additional insurance coverage, as Consultant deems adequate, at Consultant's sole expense.

10.1.1 Commercial General Liability Insurance. $2,000,000 combined single-limit per occurrence for bodily injury, personal injury and property damage. If the submitted policies contain aggregate limits, general aggregate limits will apply separately to the work under this Agreement or the general aggregate will be twice the required per occurrence limit.

10.1.2 Automobile Liability. $1,000,000 combined single-limit per accident for bodily injury and property damage.

10.1.3 Workers' Compensation and Employer's Liability. Workers' Compensation limits as required by the California Labor Code and Employer's Liability limits of $1,000,000 per accident for bodily injury.

Prior to City's execution of this Agreement, Consultant will furnish, to the satisfaction of the City, certificates of insurance and endorsements.

10.3 Cancellation. Insurance will be in force during the life of the Agreement and any extensions of it and will not be canceled without thirty (30) days prior written notice to City sent pursuant to the notice provisions of this Agreement.

10.4 Failure to Maintain Coverage. If Consultant fails to maintain any of these insurance coverages, then City will have the option to declare Consultant in breach of this Agreement, or may purchase replacement insurance or pay the premiums that are due on existing policies in order to maintain the required coverages. Consultant is responsible for any payments made by City to obtain or maintain insurance and City may collect these payments from Consultant or deduct the amount paid from any sums due Consultant under this Agreement.

10.5 Submission of Insurance Policies. City reserves the right to require, at any time, complete and certified copies of any or all required insurance policies and endorsements.

10.6 Primary Coverage. For any claims related to the Services and this Agreement, the Consultant’s insurance coverage will be primary insurance with respect to City, its officers, agents, volunteers and employees. Any insurance or self-insurance maintained by City for itself, its officers, agents, volunteers and employees, will be in excess of Consultant’s insurance and not contributory with it.

10.7 Reduction in Coverage/Material Changes. Consultant will notify City in writing pursuant to the notice provisions of this Agreement thirty (30) days prior to any reduction in any of the insurance coverage required pursuant to this Agreement or any material changes to the respective insurance policies.

10.8 Waiver of Subrogation. The policies shall contain a waiver of subrogation for the benefit of City.

11. Business License. Consultant will obtain and maintain a City of Brentwood Business License for the term of the Agreement, as it may be amended from time-to-time.

12. Maintenance of Records. Consultant will maintain complete and accurate records with respect to costs incurred under this Agreement. All records will be clearly identifiable. Consultant will allow a representative of City during normal business hours to examine, audit, and make transcripts or copies of records and any other documents created pursuant to this Agreement.

13. Ownership of Documents.

13.1 All product produced by Consultant or its agents, employees, and subcontractors pursuant to this Agreement (the “Work Product”) is the property of City. In the event this Agreement is terminated, all Work Product produced by Consultant or its agents, employees and subcontractors pursuant to this Agreement will be delivered to City pursuant to the termination clause of this Agreement. Consultant will have the right to make one (1) copy of the Work Product for Consultant’s records.

13.2 The Work Product may be used by City and its agents, employees, representatives, and assigns, in whole or in part, or in modified form, for all purposes City may deem advisable, without further employment of or payment of any compensation to Consultant; provided, however, that if this Agreement DocuSign Envelope ID: FCFC00B2-D385-476C-B135-220A5E783022 C.4.g

Consultant will not be responsible for deficiencies solely attributable to modifications of the Work Product performed by others, or that arise from use of the Documents in connection with a project or site other than that shown in the Work Product.

14. Copyrights. Consultant agrees that all copyrights that arise from the Services will be vested in City and Consultant relinquishes all claims to the copyrights in favor of City.

15. Confidentiality.

18. General Compliance with Laws. Consultant will keep fully informed of federal, state and local laws and ordinances and regulations which in any manner affect those employed by Consultant, or in any way affect the performance of the Services by Consultant. Consultant will at all times observe and comply with these laws, ordinances, and regulations and will be responsible for the compliance of the Services with all applicable laws, ordinances and regulations.

19. Pandemic Health Laws. Consultant’s duty to comply with Laws includes compliance by Consultant with all local, state, or federal Laws that have been or may be enacted in response to the COVID-19 pandemic (collectively, “Health Laws”), which include all of the County of Contra Costa Health Orders. Failure to fully comply with the Health Laws constitutes a material default, subject to all available remedies including suspension or termination.

20. Discrimination and Harassment Prohibited. Consultant will comply with all applicable local, state and federal laws and regulations prohibiting discrimination and harassment.

21. Termination. In the event of the Consultant's failure to prosecute, deliver, or perform the Services, City may terminate this Agreement for nonperformance by notifying Consultant in writing pursuant to the notice provisions of this Agreement. Consultant has five (5) business days to deliver any documents owned by City and all work in progress to City address contained in this Agreement. City will make a determination of fact based upon the work product delivered to City and of the percentage of work that Consultant has performed which is usable and of worth to City in having the Agreement completed. Based upon that finding City will determine the final payment of the Agreement. In the event City elects to terminate, City will have the right to immediate possession of all Work Product and work in progress prepared by Consultant, whether located at the project site, at Consultant's place of business, or at the offices of a subconsultant.

Either Party, upon tendering thirty (30) calendar days written notice to the other Party, may terminate this Agreement for convenience. In this event and upon request of City, Consultant will assemble the work product without charge and put it in order for proper filing and closing and deliver it to City. Consultant will be paid for work performed to the termination date; however, the total will not exceed the lump sum fee payable under this Agreement. City will make the final determination as to the portions of tasks completed and the compensation to be made.

22. Covenants Against Contingent Fees. Consultant warrants that Consultant has not employed or retained any company or person, other than a bona fide employee working for Consultant, to solicit or secure this Agreement, and that Consultant has not paid or agreed to pay any company or person, other than a bona fide employee, any fee, commission, percentage, brokerage fee, gift, or any other consideration contingent upon, or resulting from, the award or making of this Agreement. For breach or violation of this warranty, City will have the right to terminate this Agreement for nonperformance, or, in its discretion, to deduct from the Agreement price or consideration, or otherwise recover, the full amount of the fee, commission, percentage, brokerage fees, gift, or contingent fee.

23. Claims And Lawsuits. By signing this Agreement, Consultant agrees that any Agreement claim submitted to City must be asserted as part of the Agreement process as set forth in this Agreement and not in anticipation of litigation or in conjunction with litigation. Consultant acknowledges that if a false claim is submitted to City by Consultant, it may be considered fraud and Consultant may be subject to criminal prosecution. Consultant acknowledges that California Government Code sections 12650 et seq., the False Claims Act, applies to this Agreement and, provides for civil penalties where a person knowingly submits a false claim to a public entity. These provisions include false claims made with deliberate ignorance of the false information or in reckless disregard of the truth or falsity of information. If City seeks to recover penalties pursuant to the False Claims Act, it is entitled to recover its litigation costs, including attorney's fees.

Our firm’s experience includes an abundance of experience providing construction materials testing services to both public agencies and private developers, including having been the City of Brentwood’s on-call materials testing firm of choice (2016- 2021, 2011-2013, and 2004-2006). Projects for our most recently on-call contract have included; Bocce Ball Shade Structure, Traffic Calming Install – Balfour Road Sidewalk, Storm Drain Trash Capture Devices, Fuel Dispensing System and WWTP Effluent 3-Way Diversion Valve, and the New City Hall, Community Center and Parking Garage. Recent projects include Park Way Rehab, Sunset Park Trail, Municipal Service Center, WWTP Non-Potable Storage Facility, WWTP Trial Batch, and Downtown Alley Rehab at Diablo Way. CTS staff’s knowledge of the City’s terrain as well as your procedures and protocols will allow for ease of facilitation of services under this contract.

We offer the City the following additional benefits as your geotechnical/materials testing firm of choice:
 Proximity and Local Presence. Your projects will be managed locally from our Stockton office with support from our corporate office and full-service laboratory in Pleasanton.

CTS’ proposed team for this project includes civil engineers, project management specialists, multi-disciplined special inspectors and technicians. Your assigned project manager, John Lange, along with project engineers Brad Quon, GE and Dan Ventura, PE will be dedicated to your projects. Our team possesses the certifications, experience with Caltrans’ testing methods and ASTM, budgetary forecasting and project management tools and understanding of the urgent needs associated with municipal government to help meet your infrastructure goals.  Relevant Experience. In addition to our City of Brentwood experience, municipal clients for whom we have performed similar services include the cities of Oakley, Antioch, Pittsburg, Stockton, Hayward, Fremont, Livermore, Berkeley, and Vallejo as well as Contra Costa Water District, Delta Diablo Sanitation District and Contra Costa County. Our portfolio includes the kinds of infrastructure projects that are relevant to city and developer improvements such as street, sidewalk and curb rehabilitations/reconstruction and sewer/water pipeline improvements supporting housing, mixed-use and retail communities throughout Northern California.
 Responsiveness. All CTS employees carry a company cell phone for short notice after-hours and weekend availability. We understand your projects may require full-time or part-time staff, which we can accommodate for, as well as react to immediate requests due to unforeseen changes or occurrences in construction with our 24-hour dispatch.

4. Project Approach
The scope of services to be provided shall comply with the California Code of Regulations and all other related applicable standards. The inspector(s) and/or technician(s) will report to and work with City staff and will perform services including, but not limited to, observation of the contractor’s operations to ensure conformance with applicable standards. Special inspection and material testing services are to be completed within a timely manner and must comply with industry material testing standards set forth in the project specifications. Special inspection and material testing that will support all OPW and DOT divisions’ CIP projects and will include, but are not limited to:
 Concrete Testing
 Soils Compaction Testing and Materials
Analysis
 Aggregate Testing- Fine and Coarse
 Asphalt Concrete
 Slurry Seal
 Soil Corrosivity
 Reinforcing Steel
 Ph Testing
 Grout
 Asphalt Oil Content
 Structural Masonry
 Structural Steel
 Shotcrete
 Cement Treated Base
Our proposed internal management plan includes onsite and offsite special inspections and material testing services in accordance with the plans and specifications that will be provided and applicable code requirements. Before any work begins, CTS’ team will schedule a meeting to solidify a common understanding of the contract objectives and the Project Team’s expectations in procedures for each project’s plans and specifications. This will be the first step in assuring that we keep the lines of communication open between all parties involved. • Dispatch: Our inspectors are readily available; we prefer a 24-hours notice to be given prior so that we can put our best foot forward. But we also understand the complexity of schedules and schedule changes, regardless we will still work with your project team to provide services even at a moment’s notice. We hope this allows for a flexible schedule. The PMs and/or superintendent will contact our dispatcher to schedule inspections and/or sample pickups. Upon receipt of an inspection request from the project PMs and/or superintendent to our central dispatcher, ICC/AWS/ACI qualified inspectors will perform the inspection(s) as per approved project documents, applicable standards, and code requirements.
• Immediate Response: Any outstanding issues are punch-listed and reported immediately to your team for resolution. Our inspectors are equipped with the proper testing and inspection tools needed to accomplish the desired test or inspection. They also carry company cell phones and tablets, for dispatch and constant communication with supervisory staff for technical support in a timely manner. Sample pick-ups are punctual per request and transported in accordance with applicable ASTM standards to our local laboratory for further analysis and testing.
• Daily Inspection and Final Reports: We understand that the quality assurance needed for accurate reporting is important to our clients. Our approach is to provide a team that can address the required needs of the project as well as being able to quickly respond to those needs. Potential issues, if any, will be identified and rectified before being signed off. Our reporting procedures will inform you of non-conforming work immediately. Please reference the reporting procedures section below for additional information. • Engineering: Our engineers are heavily involved in our projects from report and laboratory testing reviews to actual field explorations and observations as needed. Our engineers are here to support our clients and are available for consultations and investigations. Our engineers are knowledgeable of different material types including soils, investigations, report writing, and troubleshooting possible exceptions.

Construction Support Services – In the design phase of roadway widening or new pipeline construction, for instance, we will look at the alignment and review published documents, such as geotechnical/geological data from as-builts, preliminary design plans, or maps. The intent of this preliminary pre-field activity is to identify any potential items that could impact our scope and the project. For example, if the alignment goes under a bridge or is within the public right of way, existing buried utilities or potential impact of existing foundations/structures could impact the alignment. To address this, we perform a pre-field site visit to observe and present any potential constraints to the planned scope. For example, if the site is aligned within heavily trafficked areas or within limited areas of access, we will consider alternatives, such as working at night upon approval or other alternatives as DocuSign Envelope ID: FCFC00B2-D385-476C-B135-220A5E783022 C.4.g

necessary. We will also identify and contact the agencies from whom we will need to acquire permits as well as the jurisdictional agencies for any involved utilities and/or existing foundations so that we may effectively determine plans for coordinating and scheduling our field explorations with them.

After the pre-field activities, we will coordinate and schedule for our field exploration. Depending on the project requirements, this will include rock coring, auger boring, split spoon sampling, and or test pits to collect samples and obtain field data. Staff professionals from our firm will coordinate and perform the work under the supervision of the Geotechnical Engineer. Samples retrieved will be transported to our laboratory for further analysis and design. CTS will prepare and submit the draft plans, geotechnical-related specifications, and estimate to the City for retaining wall design, engineer’s estimates of probable construction cost, and contract specifications/special provisions.

Report Preparation – For our Geotechnical Investigation and Foundation Report, we will analyze the field and laboratory data in accordance with the generally accepted geotechnical engineering practice and guidelines. For our Preliminary Engineering and Project Design Report, we will develop and study alternatives to support the development of a preferred project design concept for environmental approval, permitting, and final design.

Foundation reports will be prepared in accordance with Caltrans’ criteria. In the construction phase, our role will include providing clarification and information about the PS&E and/or geotechnical report, reviewing and commenting on contract change orders as needed, and periodically visiting the site to observe the construction and verify general compliance with the contract documents.
• Safety: The safety of our team and those on the construction site is of utmost importance. Our team is equipped with the necessary Personal Protective Equipment (PPE) including hard hats, eye protection, safety vests, etc. Our inspectors understand the critical importance of following site safety guidelines and encourage others to do the same.
• Budget Tracking: Our monthly budget analyses are provided monthly. This tool assists our clients in tracking their testing and inspections budget. We will filter in the estimated dollar amounts per scope item from the agreed-upon preliminary estimate. These amounts are then tracked monthly and discussed with our clients. • Chain of Response:
• Principal-in-Charge: Responsible for client issues, engineering, and leading the project management team.

If any issues cannot be resolved by our project team the Principal-in-Charge is available and willing to work with the client and project team to resolve any issues. • Project Manager: Responsible for the day-to-day management of the project and overseeing the field and shop inspectors, laboratory technicians, and engineers. The Project Manager will be the main point of contact for any day-to-day issues.
• Engineers: Our in-house licensed engineers are responsible for reviewing all laboratory reports. Our technicians and managers adhere to our quality assurance program. • Dispatch: Our dispatch team is available 24-hours. Although we ask that at the very least a 24-hour notice be given, we have found inspectors for a client within an hour’s time to assist our client in meeting the project scheduling deadlines.
• Field Supervisors: We have a dedicated Field Supervisor team who spend each day traveling to various job sites within the area to assure client satisfaction and assure those project deadlines are met.

Geotechnical Investigations Approach: For projects requiring geotechnical investigations, we implement a 3 phased approach. First, we gain an understanding of the project through direct communications with your team, or through review as an RFP, as to the project definable features (i.e., roadway improvements or building). This initial understanding is supplemented with review of available published documents, geologic maps, and our project files for similar projects and likely subsurface conditions that will be encountered. Second, we develop a field investigation and laboratory testing program to fit the definable features and the subsurface conditions. For example, if there are liquefiable soils, we would collect field blow counts to verify the relative density that will help to determine cyclic resistance ratio used in liquefaction analysis. If there are proposed heavy loads from the planned structure, or if there is a subterranean structure (i.e., basement or wet well), a deeper boring may be necessary to determine the groundwater levels and perspective bearing layers for foundation design. Lastly, our reporting is a compilation of the research review, field exploration and laboratory testing program, and conclusions and recommendations based on our geotechnical engineering analysis performed for the various features. The submittal could be a preliminary or final geotechnical investigation or data report containing the geotechnical engineering parameters for use in civil and structural design.

5. Quality of Work
Communication is the key to providing our best service. Our entire inspection/technical staff carries cell phones, ensuring instant availability and communication with our dispatcher who is available for 24-hour, around-the-clock response to accommodate your staffing needs. We understand that the Project Team may require a short turnaround time to dispatch inspectors to the job site and are prepared to accommodate those needs. There have been instances in which CTS is only given a minimum of four-hours’ notice for needed field testing or cancellation of services. While CTS typically requires a minimum notice of 24-hours for assignment of field testing, we will always be available and able to staff your project’s urgent needs. CTS has successfully addressed the on-call/as-needed services need of municipal agencies. By always assigning experienced, certified, and local technicians, we ensure our ability to be there and provide quality service for your projects’ needs, even at a moment’s notice. That also includes weekends and overtime. Requests for field or offsite testing services will be set up directly through our dispatcher.

You can also count on timely test results from our lab, and even a RUSH for expedited results. CTS has the in-house capability and resources to perform a lab “rush” on samples (steel, concrete, and asphalt) coming into our lab after 3 p.m. for same-day testing. We are pleased to offer this service as a value-added benefit to our client.

We generally perform and turn around Geotechnical investigation reports within 4-8 weeks upon notice to proceed. This timing is variable but usually depends on permitting driller availability, and laboratory testing. We are flexible to complete in faster deadlines based on Client and project needs.

Laboratory testing turn around times vary depending on the test but results can be reported verbally upon completion and within 24 hours after completion for the final report.

We understand that accurate and timely reporting is important to our clients. Our approach is to provide a team that can promptly address the required needs of any given project. Problems, if any, will be identified and rectified before being signed off. Our proprietary field reporting software allows for accurate and timely reporting of results. CTS’ reporting procedures will inform you of non-conforming work immediately. • Daily Field Reports: Our inspectors digitally submit daily field reports using a proprietary cloud-based web application. Our inspectors write (DFRs) Daily Field Reports at the jobsite and can send a digital copy (PDF) to any interested party (contractor, construction manager, etc.) as required. An electronic copy is then reviewed by the CTS Engineering Team the same day or the following day. • Weekly Summary Reports: Our reporting software compiles all field/shop inspections performed during the week and generates a summary of all work done on a succinct cover page. They are reviewed and edited as needed by the Operations and Engineering teams before being finalized. Digital (PDF) reports are distributed the following week to the owner, general contractor, architect, and structural engineer via e-mail (or uploaded into your reporting system) or as requested by the client. These digital (PDF) reports summarize the weekly field and shop activities as well as lab test results. CTS can submit these reports as requested by your project team. • Electronic Lab Reports: Digital laboratory testing reports are also distributed the following week from the day the laboratory test was performed, per project specifications. Sub-standard results are immediately emailed and communicated by phone to the proper team members, as well as the owner. • Immediate Response: Any outstanding issues are punch-listed and reported immediately to the client for resolution. Our inspectors are equipped with the testing and inspection tools needed to accomplish the desired test or inspection. They also carry cell phones and tablets, which allow them to communicate with field supervisors for technical support in a timely manner. Samples are picked up timely and transported in accordance with applicable ASTM standards to our local laboratory for further analysis and testing.

Following are the standard deliverables you can expect to receive and their turnaround times:
- Daily Field Report Daily at Jobsite
- Mix Design Reviews by Engineer Within One Week of Submittal (As requested by client) - Welding Procedure Specification Review Within One Week of Submittal (As requested by client) - Weekly Typed Summary Reports Weekly Basis

1.2 Consultant will control the manner and the means of the work to be performed, and be responsible for the professional quality, technical accuracy and coordination of the Services. Consultant will, without additional compensation, correct or revise any errors or deficiencies in the Services.

1.3. Consultant will keep City informed on a regular basis that the Services are being performed in accordance with the requirement and intentions of this Agreement.

1.4 If applicable, Consultant has designated those persons listed in Exhibit “A” to provide the Services to the City. Consultant will not change or reassign those persons described in Exhibit “A” without prior written notice to City, and will not replace those individuals with individuals to whom City has a reasonable objection.

2. Standard of Performance. Consultant acknowledges that in entering into this Agreement the City is relying on Consultant's special skills and experience to do and perform the Services. While performing the Services, Consultant will exercise the reasonable professional care and skill customarily exercised by reputable members of Consultant's profession practicing in the Northern California area. The acceptance of the Services by City does not release Consultant from these obligations.

Consultant will be responsible for employing or engaging all persons necessary to perform the Services.

Consultant will control the manner and means of the services to be performed by its employees and subconsultants. All of Consultant's staff will be qualified by training and experience to perform their assigned tasks.

Packet Pg. 329 Attachment: Geocon Consultants, Inc. Geotechnical Agreement (2677 : Approval of On-Call Civil/Structural, Geotechnical & Survey 2 PSA_City Attorney Approved Version 040821
Agreement by all of its employees and subcontractors, if any, and will keep the Services under its control.

On demand of City, if any employee or subcontractor of Consultant fails or refuses to carry out the provisions of this Agreement or appears to be incompetent or to act in a disorderly or improper manner, he or she will be discharged immediately from the Services.

3. Term. Unless earlier terminated, the term of this Agreement will be effective for a period of one year from the date first above written. The City Manager may amend the Agreement to extend it for two additional one-year periods or parts thereof in an amount not to exceed one hundred thousand dollars ($100,000) per Agreement year. Extensions will be based upon a satisfactory review of Consultant's performance, City needs, and appropriation of funds by the City Council. The parties will prepare a written amendment indicating the effective date and length of the extended Agreement.

4. Schedule. Consultant will generally adhere to the schedule set forth in Exhibit “A” provided, that City will grant reasonable extensions of time for the performance of the Services occasioned by unusually lengthy governmental reviews of Consultant’s work product or other unavoidable delays occasioned by unforeseen circumstances; provided, further, that such unavoidable delay will not include strikes, lockouts, work stoppages, or other labor disturbances conducted by, or on behalf of, Consultant’s officers or employees.

Consultant acknowledges the importance to City of City’s project schedule and agrees to put forth its best professional efforts to perform the Services in a manner consistent with that schedule. City understands, however, that Consultant’s performance must be governed by sound practices. Consultant will work such overtime or engage such personnel and equipment as necessary to maintain the schedule, without additional compensation.

5. Compensation.

5.1 The total fee payable for the Services to be performed during the term of this Agreement will be a not to exceed amount of one hundred thousand dollars ($100,000) as may be further specified in the attached Exhibit “A.” No other compensation for the Services will be allowed except for items covered by subsequent amendments to this Agreement. The City reserves the right to withhold a ten percent (10%) retention until City has accepted the Services.

5.2 Payment will occur only after receipt by City of invoices sufficiently detailed to include hours performed, hourly rates, and related activities and costs for approval by City.

5.3 Within thirty (30) days after receipt of any applicable progress payment request, City will verify the accuracy of the request, correct the charges where appropriate, and make payment to Consultant in an amount equal to the amount of such application, as verified or corrected by City. No payment made prior to completion and acceptance of the Services will constitute acceptance of any part of the Services.

City reserves the right to withhold payment from Consultant on account of Services not performed satisfactorily, delays in Consultant's performance of Services, or other defaults hereunder.

6. Status of Consultant. Consultant will perform the Services as an independent contractor, free from the control and direction of City, in pursuit of Consultant’s independent calling, and not as an employee of City. The persons used by Consultant to provide the Services under this Agreement will not be considered employees of City for any purposes whatsoever and City will not pay any tax, workers’ compensation insurance, retirement contributions or unemployment contributions on behalf of Consultant or its employees or subcontractors. Consultant agrees to indemnify and pay City within thirty (30) days for any tax, retirement contribution, social security, overtime payment, unemployment payment or workers’ compensation payment, including, but not limited to, those based on any provision of the Federal Affordable Care Act, which City may be required to make on behalf of Consultant or any agent, employee, or contractor of Consultant for work done under this Agreement. The payment made to Consultant pursuant to the Agreement will be the full and complete compensation to which Consultant is entitled. City will not make any federal or state tax withholdings on behalf of Consultant or its agents, employees or subcontractors.

At the City’s election, City may deduct the amounts paid pursuant to this Section, from any balance owing to Consultant.

7. Subcontracting. Consultant's services are being requested by City because they are unique and personal. Except as may be specified in Exhibit “A”, Consultant will not subcontract any portion of the Services without prior written approval of City Manager or his/her designee. If Consultant subcontracts any of the Services, Consultant will be fully responsible to City for the acts, errors and omissions of Consultant's subcontractor and of the persons either directly or indirectly employed by the subcontractor, as Consultant is for the acts and omissions of persons directly employed by Consultant. Nothing contained in this Agreement will create any contractual relationship between any subcontractor of Consultant and City.

Consultant will be responsible for payment of subcontractors. Consultant will bind every subcontractor and every subcontractor of a subcontractor by the terms of this Agreement applicable to Consultant's work unless specifically noted to the contrary in the subcontract and approved in writing by City.

8. Other Consultants. The City reserves the right to employ other consultants in connection with the Services.

9. Indemnification. Consultant agrees to indemnify, including the cost to defend, City, its officers, agents, volunteers and employees from any and all claims, demands, costs or liability that arise out of, or pertain to, or relate to the negligence, recklessness, or willful misconduct of Consultant and its agents in the performance of services under this Agreement, but this indemnity does not apply to liability for damages for death or bodily injury to persons, injury to property, or other loss, arising from the sole negligence, willful misconduct or defects in design by City or the agents, servants, or independent contractors who are directly responsible to City, or arising from the active negligence of City.

10. Insurance. Consultant will obtain and maintain, at its cost and expense, for the duration of the Agreement and any and all amendments, insurance against claims for injuries to persons or damage to property which may arise out of or in connection with performance of the Services by Consultant or Consultant’s agents, representatives, employees or subcontractors. The insurance will be obtained from an insurance carrier admitted and authorized to do business in the State of California. The insurance carrier is required to have a current Best's Key Rating of not less than "A:VII."

10.1 Coverages and Limits. Consultant will maintain the types of coverages and minimum limits indicated below, unless Risk Manager or City Manager, in consultation with the City Attorney approves a lower amount. These minimum amounts of coverage will not constitute any limitations or cap on Consultant's indemnification obligations under this Agreement. City, its officers, agents, volunteers and employees make no representation that the limits of the insurance specified to be carried by Consultant pursuant to this Agreement are adequate to protect Consultant. The coverage will contain no special limitations on the scope of its protection to the above-designated insureds except for Workers Compensation and errors and omissions insurance. Consultant will obtain occurrence coverage, excluding Professional Liability, which will be written as claims-made coverage. If Consultant believes that any required insurance coverage is inadequate, Consultant will obtain such additional insurance coverage, as Consultant deems adequate, at Consultant's sole expense.

10.1.1 Commercial General Liability Insurance. $2,000,000 combined single-limit per occurrence for bodily injury, personal injury and property damage. If the submitted policies contain aggregate limits, general aggregate limits will apply separately to the work under this Agreement or the general aggregate will be twice the required per occurrence limit.

10.1.2 Automobile Liability. $1,000,000 combined single-limit per accident for bodily injury and property damage.

10.1.3 Workers' Compensation and Employer's Liability. Workers' Compensation limits as required by the California Labor Code and Employer's Liability limits of $1,000,000 per accident for bodily injury.

10.3 Cancellation. Insurance will be in force during the life of the Agreement and any extensions of it and will not be canceled without thirty (30) days prior written notice to City sent pursuant to the notice provisions of this Agreement.

10.4 Failure to Maintain Coverage. If Consultant fails to maintain any of these insurance coverages, then City will have the option to declare Consultant in breach of this Agreement, or may purchase replacement insurance or pay the premiums that are due on existing policies in order to maintain the required coverages. Consultant is responsible for any payments made by City to obtain or maintain insurance and City may collect these payments from Consultant or deduct the amount paid from any sums due Consultant under this Agreement.

10.5 Submission of Insurance Policies. City reserves the right to require, at any time, complete and certified copies of any or all required insurance policies and endorsements.

10.6 Primary Coverage. For any claims related to the Services and this Agreement, the Consultant’s insurance coverage will be primary insurance with respect to City, its officers, agents, volunteers and employees. Any insurance or self-insurance maintained by City for itself, its officers, agents, volunteers and employees, will be in excess of Consultant’s insurance and not contributory with it.

10.7 Reduction in Coverage/Material Changes. Consultant will notify City in writing pursuant to the notice provisions of this Agreement thirty (30) days prior to any reduction in any of the insurance coverage required pursuant to this Agreement or any material changes to the respective insurance policies.

10.8 Waiver of Subrogation. The policies shall contain a waiver of subrogation for the benefit of City.

11. Business License. Consultant will obtain and maintain a City of Brentwood Business License for the term of the Agreement, as it may be amended from time-to-time.

12. Maintenance of Records. Consultant will maintain complete and accurate records with respect to costs incurred under this Agreement. All records will be clearly identifiable.

Consultant will have the right to make one (1) copy of the Work Product for Consultant’s records.

13.2 The Work Product may be used by City and its agents, employees, representatives, and assigns, in whole or in part, or in modified form, for all purposes City may deem advisable, without further employment of or payment of any compensation to Consultant; provided, however, that if this Agreement DocuSign Envelope ID: D1FF601A-44A8-44E4-9829-38B3059AE14B C.4.h

20. Discrimination and Harassment Prohibited. Consultant will comply with all applicable local, state and federal laws and regulations prohibiting discrimination and harassment.

21. Termination. In the event of the Consultant's failure to prosecute, deliver, or perform the Services, City may terminate this Agreement for nonperformance by notifying Consultant in writing pursuant to the notice provisions of this Agreement. Consultant has five (5) business days to deliver any documents owned by City and all work in progress to City address contained in this Agreement.

In the event City elects to terminate, City will have the right to immediate possession of all Work Product and work in progress prepared by Consultant, whether located at the project site, at Consultant's place of business, or at the offices of a subconsultant.

23. Claims And Lawsuits. By signing this Agreement, Consultant agrees that any Agreement claim submitted to City must be asserted as part of the Agreement process as set forth in this Agreement and not in anticipation of litigation or in conjunction with litigation. Consultant acknowledges that if a false claim is submitted to City by Consultant, it may be considered fraud and Consultant may be subject to criminal prosecution. Consultant acknowledges that California Government Code sections 12650 et seq., the False Claims Act, applies to this Agreement and, provides for civil penalties where a person knowingly submits a false claim to a public entity. These provisions include false claims made with deliberate ignorance of the false information or in reckless disregard of the truth or falsity of information. If City seeks to recover penalties pursuant to the False Claims Act, it is entitled to recover its litigation costs, including attorney's fees. Consultant acknowledges that the filing of a false claim may subject Consultant to an administrative debarment proceeding as the result of which Consultant may be prevented to act as a Consultant on any public work or improvement for a period of up to five (5) years.

PROJECT EXPERIENCE
For over 50 years, Geocon has provided professional geotechnical engineering, engineering geology, materials testing, and special inspection services to public agencies throughout California. Our offices and laboratories are geographically positioned to best serve our clients with exceptional materials testing and construction inspection services. Our experience includes numerous geotechnical engineering, construction inspection, and materials testing contracts throughout Northern California, including our current contract with the City of Brentwood:

Under our on-call agreement with the City of Brentwood, we have performed a range of services such as a geotechnical investigation on portions of Fairview Avenue and Fairview Court to evaluate the compaction characteristics of underground utility backfills that are a suspected cause of settlement; geotechnical engineering and testing services for Roadway Improvements along Lone Tree Way; geotechnical testing and observation during improvements at the City’s Wastewater Treatment Plant; materials testing for the Sycamore and Beatrice Avenue Sewer Rehabilitation Projects; geotechnical testing and special inspections for new equipment pads for Water Emergency Backup Generators; and pavement coring, materials testing, and subgrade evaluation at multiple locations throughout the City, including the 2017 PMP Slurry Seal and AC Overlay for which Geocon conducted geotechnical testing and inspection during slurry seal, AC overlay and AC repairs; and the 2017 & 2018 PMP Coring and Subgrade Evaluations. For the 2017/2018 evaluation, Geocon performed a materials investigation to evaluate pavement thickness and subgrade soils at eight locations throughout the City; we worked closely with City representativesto ensure services were provided in a responsive, thorough manner, completed at or under budget, and completed within the desired project timeframe.

Under our current agreement, we are also providing the City with geotechnical services for the design and construction of a new event center and amphitheater - The Vineyards Amphitheatre – on the west side of Vineyards Parkway. The project consists of site development and construction of an amphitheater and an 8,000 square foot Barn structure on a 31-acre site that was rough graded in the late 2000s. A wedding pavilion, two event center buildings and a variety of other amenities are also planned. Geocon conducted a geotechnical investigation to observe the soil and geologic conditions that may impact site development for the project as planned. As of the date of this SOQ, the geotechnical investigation is essentially complete, and the City has been presented with an updated draft geotechnical investigation report that reflects City design team feedback on the initial draft report that was issued in December 2021. Our geotechnical investigation identified critically expansive soils in portions of the site; recommendations to mitigate the potential effects of expansive soils were included in the project geotechnical report.

CITY OF DUBLIN ON CALL GEOLOGIC AND GEOTECHNICAL ENGINEERING AND MATERIALS TESTING SERVICES Geocon is currently performing professional geologic and geotechnical engineering and materials testing services for the City of Dublin under a multiyear agreement. Since 2012 we have supported the City with on-call services for Capital Improvement Projects throughout the City. Under this on-call, Geocon performed a range of services for the failing Alamo Creek Trail. Geocon performed a geotechnical investigation for the trail, which was showing signs of distress throughout the asphalt and rigid concrete pavement sections.

Historically, the trail required frequent maintenance to preserve the City’s desired level of serviceability. Geocon performed an investigation to observe the soils conditions and evaluate potential causes of distress along the trail. Upon completion of our investigation, we recommended that the City remove existing trail pavements and replace them with a conventional asphalt pavement section that incorporated geosynthetic reinforcement to mitigate the potential for future tension cracking in the trail pavement. Geocon later provided the City with civil design services and geotechnical testing and observation services during reconstruction of the trail. Our civil design services included design and plan preparation for the removal of existing pavements and construction of new asphalt pavement section; development of specifications; and providing an engineer’s estimate of probable construction costs. Total project cost: $665,000

PROJECT APPROACH
All of Geocon’s projects are managed with the ultimate goal to produce technically sound, economically feasible solutions. This is achieved by considering construction costs and client needs in conjunction with site conditions and engineering requirements. Our innovative and practical solutions to complex geotechnical and environmental challenges have resulted in a substantial percentage of repeat-client work. Our project managers are selected to provide oversight of daily activities and communicate details with our senior management to ensure successful and timely project completion. Field services will be invoiced portal-to-portal from our Livermore office location, per the fee schedule in Appendix C. Minimum daily charges will not apply to dedicated trips for sample pickup.

SCHEDULE CONTROL
Schedules for geotechnical investigations are typically driven by the availability of drilling subcontractors and agency permitting timelines. Once the scope of a geotechnical investigation is developed and agreed upon with the City, Geocon will immediately contact relevant subcontractors and agency personnel to determine availability and anticipated permit turnaround times, respectively. Geocon will review that information in conjunction with staff field scheduling and then provide the City with accurate and achievable timelines for milestones such as drilling, laboratory testing and report delivery.

Materials testing and special inspections will be conducted/scheduled as determined by the owner’s or general contractors’ schedule. Once a project moves into construction, the onsite schedule is controlled by the general contractor and/or construction manager. While this schedule (and the means and methods of the contractor) is not controlled by Geocon, our large pool of in-house engineers and technicians make it possible to respond quickly to inspection requests, thus eliminating delays and potential added costs to the City.

Costs for testing and inspection services are typically billed in two-hour increments. Technicians and inspectors are dispatched based on their place residence or anticipated field schedule, allowing us to shorten travel time, as well as accommodate last-minute inspection requests. This also aids in rapid pick-up and transportation of samples from the project site to the Geocon laboratory. Furthermore, our statewide in-house laboratories assist in short turnaround of laboratory testing.

ENVIRONMENTAL AND PERMITTING CHALLENGES
Geocon is diligent to address the needs of environmentally sensitive areas and work with appropriate agency oversight to adhere to protocols. Our staff understands the importance of direct communication that establishes a dialogue of understanding concerning scope of work and project milestones. Based on our experience, potential impacts on the critical path (such as environmental permitting and regulatory agency approvals) are identified early to reduce impacts to project schedule and allow for contingency planning. Our primary goals are to perform our field investigations with minimal environmental, impact and to effectively evaluate the geotechnical and geological conditions at the projectsite and develop cost-effective solutions for geotechnical-related design while maintaining our ethical obligation of protecting the safety, health, and welfare of the public.

SCOPE OF WORK
Geocon has thoroughly reviewed the RFQ dated February 1, 2022, and we are prepared to provide the City with professional and cost-effective geotechnical engineering, special inspection, and materials testing services for the Infrastructure Projects. Based on our review of the RFQ and the Capital Improvement Program 2021/22 – 2025/266, we understand that potential projects will include parks and trail improvements, PMP/roadway improvements, water distribution, and other, as-needed construction.

SPECIAL INSPECTIONS AND MATERIALS TESTING

technicians/special inspectors for this contract have the necessary certifications to perform the services outlined in the RFQ. Our standard testing and inspection procedures are as follows:
• When Geocon receives an inspection request from the City or their representative (Construction Manager, Project Manager, Superintendent, Owner’s Authorized Representative, and/or IOR), we document the request in writing including the date and time of the inspection, type of inspection requested, person requesting the inspection, and a contact phone number.
• We verify that the person requesting the inspection has been authorized by the City to request the inspection.

Once all information has been verified, Geocon dispatch will schedule the requested inspection(s). • On the day of inspection, Geocon’s Inspector will meet the appropriate onsite City representative to verify the type and location of inspection needed.
• Inspections will be performed in accordance with project specifications and City and/or County requirements. • The inspector will provide daily written reports of inspection indicating compliance or non-compliance, which are to be signed by the City representative before our inspector leaves the project site. Reports detail the inspector’s arrival and departure times, as well as specific details about activities performed. • The inspector obtains samples as required and transports them to our in-house laboratory for testing and analysis.

Deliverables
Following field inspection services, Geocon’s inspector will provide a hand-written copy of the completed field report for signature to the City, prior to departure. Geocon will submit copies of each certified written report of each inspection, test or similar service, to all parties as coordinated with the City.

D. AGREEMENT PROVISIONS
Geocon’s legal team has reviewed the City’s Professional Services Standard Agreement that was provided with the RFQ and respectfully requests the following modifications in accordance with Civil Code section 2782.8 and current industry standards:
• Section 5.1 – The last sentence regarding retention should be deleted entirely as retention holding is not applicable to design professional services.
• Section 7 - The majority of the subcontractors Geocon Consultants hires do not carry more than the industry standard limits for General Liability insurance ($1,000,000 per claim) and ever fewer carry any kind of Umbrella Liability coverage to meet the $2,000,000 requirements in Section 10.1.1. Furthermore, the majority of our subcontractors are contractors who not required to carry Professional Liability insurance as it is not applicable to their trade. To require our subcontractors to purchase additional insurance to meet these requirements be an undue financial burden as the additional insurance premiums would far exceed their fees.
• Section 9 – This section requires numerous edits to make it insurable under a design professional’s insurance policies and for compliance with CA Civil Code section 2782.8. • Section 10 – This section requires numerous edits for insurability, including but not limits to: revising the first sentence of Section 10 as Geocon’s insurance does not cover actions by other agents, representatives, or subcontractors (we require these entities to provide their own insurance), deleting the section sentence of Section 10.1, deleting the terms “agents” and “volunteers” as additional insured entities (vague and overbroad), making it clear primary/non-contributory coverage is only available under General and Automobile Liability in Section 10.6, and adding additional language to Section 10.8 clarifying that Geocon Consultants’ Professional Liability policy can provide waiver of subrogation coverage per policy form as required by written contract only (no physical endorsements can be provided).

Subject: SUMMARY OF GEOTECHNICAL OBSERVATION, MATERIALS TESTING,

AND SPECIAL INSPECTION SERVICES

RICHFIELD PARK IMPROVEMENTS
1900 EXPEDITION WAY

SACRAMENTO, CALIFORNIA
Dear Ms. Wong:

In accordance with the Professional Services Agreement between Geocon and the City of Sacramento dated June 12, 2017, we provided geotechnical observation, materials testing, and special inspection services during construction of improvements at Richfield Park, 1900 Expedition Way in Sacramento, California.

This letter summarizes the results of our services.

SCOPE OF SERVICES
In accordance with Chapter 17 of the California Building Code (CBC), we provided special inspection and materials testing services during the period of December 8, 2017 through March 12, 2018. Specifically, we:
 Performed compaction testing on compacted aggregate base (AB) material placed in walkways and the picnic area,
 Observed concrete placement for walkways, measured temperature, slump and cast concrete test cylinders,
 Cured and tested concrete cylinder samples for compressive strength, and  Observed installation and tightening (snug-tight) of A325 high strength bolts.

We evaluated the degree of relative compaction and moisture content of AB by performing field inplace density tests. Testing was performed using nuclear testing equipment to obtain densities and moisture contents in accordance with American Society for Testing and Materials (ASTM) D6938 test procedure. Field test results were compared to referenced laboratory compaction curves prepared in accordance with ASTM D1557 to obtain the percent relative compaction. In-place density and laboratory test results are summarized in our field reports and retained in our files. The results of our in-place density testing indicate that the minimum relative compaction required for the project was generally met.

Concrete test specimens were fabricated during the concrete pour. Concrete cylinders were fabricated, transported, and cured in general accordance with ASTM C31 and were tested for compressive strength in general accordance with ASTM C39. Test results are attached to this letter.

CONCLUSIONS
Based on our testing and observations, it is our opinion that the observed work was performed in general conformance with the approved plans, specifications, applicable design professional revisions, and the applicable workmanship provisions of the CBC.

LIMITATIONS
We provided the requested testing and observation services on an on-call basis. Therefore, the conclusions contained herein pertain only to the work that we observed and/or tested. Our conclusions are based on conditions at the date of our last site visit, March 12, 2018. As used herein, the term "observation" implies only that we observed the progress of the work with which we agreed to be involved. Our services were performed in accordance with engineering principles and practices generally accepted at this time and location. We make no warranty, express or implied.

GEOTECHNICAL INVESTIGATION

1. PURPOSE AND SCOPE
This report presents the results of our geotechnical investigation for the new event center and amphitheater planned on the southwestern side of Vineyards Parkway in Brentwood, California. A Vicinity Map is presented as Figure 1. The purpose of this investigation was to evaluate the subsurface soil and geologic conditions in the area of planned development and provide conclusions and recommendations pertaining to the geotechnical aspects of project design and construction, based on the conditions encountered during our study.

The scope of this investigation included field exploration, laboratory testing, engineering analysis and the preparation of this report. Our field exploration was performed between August 11 and November 30, 2021 and included 11 exploratory test pits to maximum depths of approximately 10 ½ feet and 16 exploratory borings to maximum depths of approximately 29 ½ feet below existing grade at the site. The locations of the test pits and soil borings are depicted on the Site Plan, Figure 2. A detailed discussion of our field investigation, test pit logs, and boring logs are presented in Appendix A.

Laboratory tests were performed on selected soil samples obtained during the investigation to evaluate pertinent geotechnical parameters. Appendix B presents our laboratory test results in tabulated and graphic forms.

If project details vary significantly from those described herein, Geocon should be contacted to determine the necessity for review and possible revision of this report.

2. SITE CONDITIONS AND PROJECT DESCRIPTION
The irregularly shaped site is an assembly of five adjacent parcels on the southwestern side of Vineyards Parkway in Brentwood, generally south and east of the Vineyards Phase 5B residential subdivision. Contra Costa County APN Nos. 007-640-012 through -016 are assigned to the five parcels.

The project site is generally undeveloped and covered with grass. However, current site topography was shaped by previous grading activities in the mid-2000s. The site was originally a rolling hillside that sloped toward the Marsh Creek valley that bounds the southeast margin of the site. Ground surface elevations ranged from approximately 340 feet MSL at the southwestern corner of the site to approximately 170 feet MSL at the southeastern margin.

Post-grading, the site is characterized by a prominent east-facing hillside at the western margin, with large, relatively flat tiers below at elevations of around 220 to 230 feet MSL. Two graded swales direct runoff generally northward toward Vineyards Parkway. One swale is located below, and parallel to, the adjacent residential subdivision at the northwestern corner of the site. The other swale is situated behind the top of the tall, graded slope that descends to the Marsh Creek valley; this swale flows to a corrugated storm drain at the northeastern corner of the site, which presumably connects to existing storm drain infrastructure in Vineyards Parkway.

Vineyards Parkway was constructed with driveway returns at the north and east corners of the site. Current site topography is depicted on the Site Plan, Figure 2.

Mass grading began in early August 2005 with the construction of a long keyway along the southeastern margin of the site. From August into September 2005, grading continued with colluvium removals, subdrain construction and fill placement for the slope above the keyway and the area to the west. The referenced grading report indicates that three additional keyways were constructed: 1. A keyway along the southern margin of the site 2. A keyway within the slope that descends to Vineyards Parkway; and 3. A toe keyway for the fill slope that rises to the adjacent residential subdivision northwest of the site. A fourth keyway was started but not finished on the east-facing slope that ascends to the highest points of the site.

Subdrain lines were constructed within the keyways at the southern and southeastern margin, and at the bottom of the swale fill that progressed westward. These subdrains lines are interconnected and outlet toward Marsh DocuSign Envelope ID: D1FF601A-44A8-44E4-9829-38B3059AE14B C.4.h

Creek east of the site. A keyway subdrain was installed at the base of the fill slope for the adjacent homes and reportedly outlets to the swale that directs run-off to the northern corner of the site. No subdrain was reported within the keyway for the northern slope that descends to Vineyards Parkway. Approximate subdrain locations and spot elevations are shown on Figures 2 and 3.

Based on the current site layout concept (DLR Group, September 2021), the proposed project will consist of site development and construction of an amphitheater within the lower southern tier and an 8,000 square foot barn structure (Barn) with covered gathering area and entry canopy on the northern tier. A wedding pavilion is planned approximately 150 feet southeast of the entry canopy. Two future event center buildings are sited due west of the wedding pavilion, at the base of the east-facing slope.

Vehicular access off Vineyards Parkway will be provided at two points – one at the northern corner of the site and the other at the eastern corner. Underground utilities will be routed into the site at both driveway entrances.

Surface parking will be provided on the northern site tier. An emergency vehicle driveway will access the amphitheater along the top of the tall slope that descends to the Marsh Creek valley. A variety of exterior flatwork, landscaped areas, footpaths and amenity open spaces are also planned. Site grading for this project will be relatively minor, with design grades generally aligned with current topography. However, cuts of up to approximately 10 feet deep are planned for the Barn and adjacent gathering area. The proposed site layout is presented on the Site Development Plan, Figure 3.

3. GEOLOGIC SETTING
Brentwood is located within the western portion of the Great Valley Geomorphic Province of California, more commonly known as the Central Valley. The valley is a broad lowland between the Sierra Nevada to the east and Coast Ranges to the west. The Central Valley has been filled by a sequence of deep alluvial deposition derived from weathering processes in the Sierra Nevada and Coast Ranges. The weathering and subsequent deposition within the valley has resulted in alluvium that can be thousands of feet in thickness. The site lies with the hills that ascend from the western margin of the valley floor.

Available geologic mapping (see List of References) indicates the western margin of the site is underlain by Upper Cretaceous-age Deer Valley Formation materials, Pleistocene-age alluvial deposits mantle much of the northern portion of the site, and the remaining areas of the site are underlain by Eocene-age Meganos Formation materials. To the southeast of the site, the native soils adjacent to Marsh Creek are Holocene-age alluvium deposits.

4. GEOLOGIC HAZARDS

4.1 Faulting and Seismicity
Geologists and seismologists recognize the San Francisco Bay Area as one of the most seismically active regions in the United States. The significant earthquakes that occur in the Bay Area are associated with crustal movements along well-defined active fault zones that generally trend in a northwesterly direction.

The site and greater Bay Area are seismically dominated by the presence of the active San Andreas Fault System.

In the theory of plate tectonics, the San Andreas Fault System is a transform fault that forms the boundary between the northward moving Pacific Plate (west of the fault) and the southward moving North American Plate (east of the fault). Locally, the movement is distributed across a complex system of strike-slip, right lateral parallel and subparallel faults, which include the San Andreas, Hayward and Calaveras faults, among others.

The table below presents approximate distances to active faults in the site vicinity based on web-based mapping by the USGS and CGS. Site latitude is 37.8932° N, 121.7278° W.

The faults tabulated and discussed above and numerous other faults in the greater Bay Area are sources of potential ground motion. However, earthquakes that might occur on other faults within the northern and central California area are also potential generators of significant ground motion and could subject the site to significant ground shaking.

Prior geologic studies indicate the Brentwood Fault crosses the site. The fault line generally trends northnorthwest to south-southeast. Site specific studies and those by the State of California for the Los Vaqueros Dam concluded the Brentwood Fault has not experienced movement in at least 40,000 to 75,000 years. Therefore, the fault is not considered active.

4.2 Surface Fault Rupture
The site is not within a currently established State of California Earthquake Fault Zone for surface fault rupture hazards. No active faults are known to pass directly beneath the site. By definition, an active fault is one with surface displacement within the last 11,000 years. A potentially active fault has demonstrated evidence of surface displacement with the past 1.6 million years. Faults that have not moved in the last 1.6 million years are typically considered inactive. As noted in the preceding section, the Brentwood Fault has not experienced movement in at least 40,000 years and is classified as potentially active by California Geological Survey definition. The potential for surface rupture in the area of the planned development, due to faulting occurring beneath the site, during the design life of the proposed development is considered low.

4.3 Ground Shaking
We used the USGS web-based Unified Hazard Tool to estimate the peak ground acceleration (PGA) and modal (most probable) magnitude associated with a 2,475-year return period that corresponds to an event with 2 percent chance of exceedance in 50 years. The USGS estimated PGA is 0.76g and the modal magnitude is 6.9 for Seismic Site Class C/D (Vs30 = 360 m/sec) based on a recent 2014 model within the application.

While listing PGA is useful for comparison of potential effects of fault activity in a region, other considerations are important in seismic design, including frequency and duration of motion and soil conditions underlying the site.

4.4 Liquefaction
The site is not located within a State of California Seismic Hazard Zone for liquefaction and interactive web-based mapping by USGS indicates the site soils possesses a “very low” susceptibility to liquefaction. Liquefaction is a phenomenon in which saturated cohesionless soils are subject to a temporary loss of shear strength due to pore pressure buildup under the cyclic shear stresses associated with intense earthquakes. Primary factors that trigger liquefaction are moderate to strong ground shaking (seismic source), relatively clean, loose granular soils (primarily poorly graded sands and silty sands), and saturated soil conditions (shallow groundwater). Due to the increasing overburden pressure with depth, liquefaction of granular soils is generally limited to the upper 50 feet of a soil profile.

Based on the cohesive nature of much of the materials that underly the site, the dense and hard nature of the formational materials that underlie the site, and the depth to groundwater, the potential for liquefaction occurring within the site soils is considered low.

4.5 Tsunamis and Seiches
The site is not located within a coastal area. Therefore, tsunamis (seismic sea waves) are not considered a significant hazard at the site.

Seiches are large waves generated in enclosed bodies of water in response to ground shaking. Marsh Creek Reservoir is down gradient from the project site. No major water-retaining structures are located immediately up gradient from the project site. Flooding from a seismically induced seiche is considered unlikely.

5. SOIL AND GROUNDWATER CONDITIONS

5.1 Fill
Our Borings B2, B5, B6, B8, B9, B10, and B12 through B16 and our Test Pits TP2 through TP7 and TP11 encountered fills placed during site grading performed in the mid-2000s. The fill materials were observed as loose to medium dense silty sands with variable amounts of clay and gravel, loose to dense clayey sands with variable amounts of gravels and occasional cobbles, medium stiff to very stiff silts with variable amounts of sand, clay and gravel, and soft to hard clays with variable amounts of sand, gravel, and silt and occasional cobbles, medium dense clayey gravels with silt and sand, and very dense sandy gravel. Maximum fill thicknesses were observed in our borings within the former swale fill that underlies the amphitheater area. Our Borings B6 and B12 encountered artificial fill to the maximum depths explored – approximately 20 and 29 ½ feet below existing grade, respectively. The referenced grading report indicates fill thickness up to approximately 40 feet exist within the amphitheater footprint, with thicker fills present at the top of the slope that descends toward Marsh Creek.

Our laboratory testing indicates the clayey soils within the fills that mantle portions of the site are expansive.

5.2 Older Alluvium
Our Test Pits TP6 and TP7 encountered Pleistocene-age alluvium beneath the existing fills and in our Boring B1 at grade. The older alluvium was observed as stiff to hard fat clays with variable amounts of sand and gravel. We encountered older alluvium in our soil boring and test pits at the site to the maximum depth explored – approximately 15 feet below grade. Our laboratory testing indicates the older alluvial soils are highly expansive.

5.3 Colluvium
Our Test Pits TP2 and TP3 encountered colluvial deposits beneath the existing fills and in our Test Pit TP1 at grade. The colluvium was observed as medium stiff to hard clays with variable amounts of silt, sand, and gravel.

We encountered colluvium in our test pits to maximum depths of approximately 9 ½ feet below grade.

5.4 Meganos Formation
Eocene-age Meganos Formation was encountered at-grade in Borings B3, B4, B7, B8 and B11 and Test Pits TP8 through TP10, in our Borings B2, B5,B8 through B10, and B13 through B16 and Test Pits TP4, and TP5 beneath the existing fills, and in our Test Pit TP1 beneath the existing colluvium. Meganos Formation materials were observed as stiff to hard clays with variable amounts of sand, silt and gravel and occasional cobbles, very stiff fat clays with sand, stiff silts with sand and clay, dense to very dense silty sands with clay, dense clayey sands with variable amounts of gravel, sandstone, siltstone, and claystone. Crystalline mineral deposits which appear to be gypsum were observed sporadically within the formational materials. We encountered Meganos Formation materials in our soil borings and test pits at the site to the maximum depth explored – approximately 24 ½ feet below grade.

5.5 Groundwater
Groundwater was not encountered during our field exploration. Historic high groundwater levels are not mapped by CGS at the site, but historic high groundwater levels immediately southeast of the site, in the Marsh Creek valley bottom, are less than 10 feet below natural grade.

Actual groundwater levels will fluctuate with variations in rainfall, temperature and other factors and may be higher or lower than observed during our study. Additionally, it is not uncommon for perched groundwater conditions to develop where none previously existed, especially in or atop fine-grained soils which are subjected to irrigation or precipitation.

5.6 Soil Corrosion Screening
Soil samples obtained during our field exploration were subjected to laboratory testing for minimum resistivity, pH, and chloride and water-soluble sulfate. The laboratory test results and published screening levels are presented in Appendix B. Soil corrosivity should be considered in the design of buried metal pipes, underground structures, etc.

Water-soluble sulfate test results on selected samples of site alluvial soils indicate an S0 exposure classification for sulfate attack on normal portland cement concrete (PCC) as defined in Chapter 318, Table 19.3.1.1 of the ACI Building Code Requirements for Structural Concrete. No special provisions are specified by ACI for S0 exposure classification soils. Based on the Caltrans’ criteria, the soils represented by our laboratory corrosion test results are not considered corrosive to foundation elements or buried metal. However, based on the resistivity values of the tested soils, the site soils indicate a higher propensity for corrosion.

Geocon does not practice in the field of corrosion engineering and mitigation. If corrosion sensitive improvements are planned, it is recommended that a corrosion engineer be retained to evaluate corrosion test results and incorporate the necessary precautions to avoid premature corrosion of buried metal pipes and concrete structures in direct contact with the soils.

6. CONCLUSIONS AND RECOMMENDATIONS

6.1 General

6.1.1 It is our opinion that neither soil nor geologic conditions were encountered during our investigation that would preclude the project as presently proposed.

6.1.2 Key geotechnical constraints to the project are the presence of deep artificial fills and expansive soils.

The soils and claystone materials within the area of the planned Barn and large parking lot are critically expansive Proper soil moisture conditioning, compaction, surface drainage, and slope protections are recommended to reduce the shrink-swell potential of the site soils. A layer of low-expansive material will be required beneath interior slabs-on-grade and exterior flatwork and rigid pavements.

6.1.3 The tall fill slope at the southeast margin of the site was graded during mass grading operations in 2005. Based on our review of current slope conditions, information in the referenced grading report, the soils conditions encountered in our subsurface explorations and our laboratory test results, the slope appears generally stable and the fill materials are well compacted. The slope has performed well over the past 15 years and exhibits no overt indications failure or sloughing. We did observe significant animal burrowing at the toe of the slope. Animal burrowing is destructive and can compromise the integrity of slopes as it fundamentally weakens the fill mass and provides potential conduits for surface water intrusion. From a geotechnical standpoint, consideration should be given to filling existing animal burrows and/or other deterrence measures.

6.1.4 Based on the observed soil conditions and the assumed structural loading, we anticipate that conventional shallow foundation systems consisting of strip footings can be used to support the proposed event center, amphitheater, Barn, and wedding pavilion structures.

6.1.5 Remedial grading will be required at the Barn, amphitheater and event center structures. Specific grading recommendations for each area are provided herein.

6.1.6 Post-construction settlement will be a function of foundation loading and the thickness of fill materials beneath each structure. Provided the site is graded in accordance with the recommendations of this report and foundation systems are constructed as described herein, we estimate that postconstruction settlements for the Barn and wedding pavilion will be less than approximately ¾ inch and corresponding differential settlement will be approximately ½ inch or less across a horizontal distance of 50 feet. Post-construction settlements for the amphitheater and event center buildings are estimated to be on the order of 1 ½ inches or less with corresponding differential settlement of approximately 1 inch or less across a horizontal distance of 30 feet. Final design foundation loadings should be reviewed by Geocon.

6.1.7 Geocon should be retained to provide geotechnical input and engineering support during project design. Any changes in the design, location or elevation of the proposed improvements, as outlined in this report, should be reviewed by this office. Geocon should be contacted to determine the necessity for review and possible revision of this report.

6.2 Seismic Design Criteria

6.2.1 Seismic structural design will be performed in accordance with the provisions of the 2019 CBC which is based on the American Society of Civil Engineers (ASCE) publication Minimum Design Loads for Buildings and Other Structures (ASCE 7-16). We used the Structural Engineers Association of California web-based application Seismic Design Maps to evaluate site-specific seismic design DocuSign Envelope ID: D1FF601A-44A8-44E4-9829-38B3059AE14B C.4.h

parameters in accordance with the 2019 CBC and ASCE 7-16. Results are summarized in Table 6.2.1.

The values presented are for the risk-targeted maximum considered earthquake (MCER) and Seismic Risk Category II. We have assigned Site Class C to the Barn and wedding pavilion structures. Site Class D should be used for the amphitheater and event center structures.

6.3 Soil and Excavation Characteristics

6.3.1 The onsite soils can be excavated with moderate to heavy effort using conventional excavation equipment. We anticipate excavations in the fills or native formational materials at the site may generate oversize material (greater than 6 inches in nominal dimension) that should not be used in engineered fills.

6.3.2 It is the responsibility of the contractor to ensure that all excavations and trenches are properly shored and maintained in accordance with applicable Occupational Safety and Health Administration (OSHA) rules and regulations to maintain safety and maintain the stability of adjacent existing improvements.

6.3.3 Our laboratory testing indicates the site soils encountered in our field exploration are expansive (Expansion Index higher than 20) as defined by 2019 California Building Code (CBC) Section 1803A.5.3. Based on our experience in the area and laboratory test results, the recommendations herein reflect the presence of soils with moderate to very high expansion potential. In general, the site soils with very high expansion potential are present within the barn and entry canopy area and throughout the large parking lot to the northeast. Recommendations to mitigate the expansion potential of those soils are provided herein.

6.4 Materials for Fill

6.4.1 Excavated soils generated from cut operations at the site are suitable for use as engineered fill in structural areas provided they do not contain deleterious matter, organic material, or cementations larger than 6 inches in maximum dimension. However, excavated claystone materials and clayey alluvial soils may not be used as engineered fill in structural areas without lime-treatment or further review by Geocon.

6.4.2 Import and low-expansive fill material should be primarily granular with a “low” expansion potential (Expansion Index less than 50), a Plasticity Index less than 15, be free of organic material and construction debris, and not contain rock larger than 6 inches in greatest dimension. Low-expansive fill may also consist of aggregate base or lime-treated native soils. Laboratory testing should be performed to determine the required percentage of lime; for planning purposes approximately 6% quicklime by dry weight may be assumed.

6.4.3 Environmental characteristics and corrosion potential of import soil materials may also be considered.

Proposed import materials should be sampled, tested, and approved by Geocon prior to its transportation to the site.

6.5 Grading

6.5.1 All earthwork should be observed and all fills tested for recommended compaction and moisture content by representatives of Geocon.

6.5.2 Structural building pad areas should be considered as areas extending a minimum of 5 feet horizontally beyond the outside dimensions of buildings, including footings and overhangs carrying structural loads, where not restricted by property boundaries.

6.5.3 A preconstruction conference should be held at the site prior to the beginning of grading operations with the owner, contractor, civil engineer and geotechnical engineer in attendance. Special soil handling requirements can be discussed at that time.

6.5.4 Site preparation should commence with the stripping of any organic-laden near-surface soils and the removal of any existing improvements from the area to be graded and developed. All active or inactive DocuSign Envelope ID: D1FF601A-44A8-44E4-9829-38B3059AE14B C.4.h
Packet Pg. 437 Attachment: Geocon Consultants, Inc. Geotechnical Agreement (2677 : Approval of On-Call Civil/Structural, Geotechnical & Survey Project No. E8689-04-14 - 9 - December 13, 2021
utilities within the construction area should be protected, relocated, or abandoned. Any pipelines to be abandoned that less than 18 inches in diameter should be removed or filled with sand-cement slurry. Utilities larger than 18 inches in diameter should be removed. Excavations or depressions resulting from site clearing operations, or other existing excavations or depressions, should be restored with engineered fill in accordance with the recommendations of this report.

6.5.5 Where not removed by stripping operations, subgrade soils in the proposed building pad areas should be over-excavated as outlined below. Deeper over-excavations may be recommended during grading operations if soft soils, poorly compacted fills, or other unsuitable conditions are encountered. Specific grading recommendations for each building area and the planned parking lot are as follows:

Barn and Entry Canopy Area
Due to the presence of very highly expansive soils, we recommend that subgrade soils for the Barn pad and adjacent entry canopy and covered gathering area be over-excavated to approximately 5 feet below existing or proposed grade (whichever is lower). The over-excavated bottom should be limetreated to a depth of approximately 12 inches. Engineered fill, consisting of lime-treated native soils, should be placed and compacted in lifts to attain design subgrade elevation.

Amphitheater
We recommend that subgrade soils for the amphitheater pad be over-excavated to approximately 5 feet below existing or proposed grade (whichever is lower). The over-excavated bottom should be scarified to a depth of approximately 12 inches, moisture conditioned to at least 2% above optimum moisture contact and recompacted to at least 90% relative compaction. Engineered fill, consisting of over-excavated materials, should be placed and compacted in lifts to attain design subgrade elevation. The upper 12 inches of material below design subgrade should meet the requirements of Section 6.4.2.

Wedding Pavilion
Subgrade soils for the wedding pavilion pad should scarified to a depth of approximately 12 inches, moisture conditioned to near optimum moisture contact and recompacted to at least 90% relative compaction.

Event Center Buildings
We recommend that subgrade soils for the event center building pads be over-excavated to approximately 5 feet below existing or proposed grade (whichever is lower). The over-excavated bottom should be scarified to a depth of approximately 12 inches, moisture conditioned to at least 2% above optimum moisture contact and recompacted to at least 90% relative compaction.

Engineered fill, consisting of over-excavated materials, should be placed and compacted in lifts to attain design subgrade elevation. The upper 12 inches of material below design subgrade should meet the requirements of Section 6.4.2. Grading operations should result in at least 5 feet of new compacted fill materials across each building pad.

Parking Lot
Due to the presence of very highly expansive soils, we recommend that subgrade soils for the parking lot and associated driveways be over-excavated to approximately 1 foot below existing or proposed grade (whichever is lower). The over-excavated bottom should be lime-treated to a depth of approximately 12 inches. Engineered fill, consisting of lime-treated native soils, should be placed and compacted in lifts to attain design subgrade elevation.

6.5.6 Lime treatment may be implemented to utilize site soils as low-expansive fill and improve the durability of finished subgrade with the respect to wet weather conditions and construction traffic. For planning DocuSign Envelope ID: D1FF601A-44A8-44E4-9829-38B3059AE14B C.4.h
Packet Pg. 438 Attachment: Geocon Consultants, Inc. Geotechnical Agreement (2677 : Approval of On-Call Civil/Structural, Geotechnical & Survey Project No. E8689-04-14 - 10 - December 13, 2021
purposes, it should be assumed that soils will be treated with approximately 6% lime by dry weight.

The lime material should be Hi-Calcium quicklime and an in-place soil density of 120 pounds per cubic foot may be assumed. Lime-treatment should include two mixing periods with both mixes to the same depth. The second mixing should occur approximately 24 hours after initial mixing. Lime-treated soils should be compacted to at least 90% relative compaction. Comprehensive quality control testing should be implemented during lime treatment operations.

6.5.7 If grading commences in winter or spring, or in periods of precipitation, excavated and in-place soils may be wet. Earthwork contractors should be aware of potential compaction/workability difficulties.

The most effective site preparation alternatives will depend on site conditions prior to and during grading operations; we should evaluate site conditions at those times and provide supplemental recommendations, if necessary.

6.5.8 All engineered fill should be placed in layers no thicker than will allow for adequate bonding and compaction (typically 8 inches). Fill soils should be placed, moisture conditioned to at least 2% above optimum moisture content (near optimum if sand or gravel) and compacted to at least 90% relative compaction. Fill areas with in-place density tests showing moisture contents below those recommended herein will require additional moisture conditioning, processing and recompaction prior to placing additional fill or constructing overlying improvements.

6.6 Temporary Excavations

6.6.1 We anticipate that the majority of the site soils will be classified as Cal-OSHA “Type B” soil when encountered in excavations during site development and construction. If active seepage, loose gravelly or sandy soil, or poorly compacted fills are encountered, the Cal-OSHA classification should be downgraded to “Type C”. Excavation sloping, benching, the use of trench shields, and the placement of trench spoils should conform to the latest applicable Cal-OSHA standards. The contractor should have a Cal-OSHA-approved “competent person” onsite during excavation to evaluate trench conditions and make appropriate recommendations where necessary.

6.6.2 All onsite excavations must be conducted in such a manner that potential surcharges from existing structures, construction equipment, and vehicle loads are resisted. The surcharge area may be defined by a 1:1 projection down and away from the bottom of an existing foundation or vehicle load.

Penetrations below this 1:1 projection will require special excavation measures such as sloping and possibly shoring.

6.6.3 It is the contractor’s responsibility to provide sufficient and safe excavation support as well as protecting nearby utilities, structures, and other improvements which may be damaged by earth movements.

6.6.4 Temporary excavations such as utility trench sidewalls within site soils should remain near vertical to depths of at least 4 feet below ground surface, although some sloughing and caving may occur, particularly if clean sandy or gravelly soils, poorly compacted fills or groundwater are encountered.

Excavations greater than approximately 4 feet in height or those that are surcharged by adjacent traffic or structures may require sloping or shoring measures in order to provide a stable excavation.

6.6.5 Temporary excavations should be protected from rainfall and erosion. Surface runoff should be directed away from excavations or slopes.

6.7 Underground Utilities

6.7.1 Underground utility trenches should be backfilled with properly compacted material. The material excavated from the trenches should be adequate for use as backfill provided it does not contain DocuSign Envelope ID: D1FF601A-44A8-44E4-9829-38B3059AE14B C.4.h
Packet Pg. 439 Attachment: Geocon Consultants, Inc. Geotechnical Agreement (2677 : Approval of On-Call Civil/Structural, Geotechnical & Survey Project No. E8689-04-14 - 11 - December 13, 2021
deleterious matter, vegetation or rock larger than six inches in maximum dimension. Trench backfill should be placed in loose lifts not exceeding eight inches and compacted to at least 90% relative compaction at least 2% above optimum moisture content (near optimum if sand or gravel).

6.7.2 Bedding and pipe zone backfill typically extends from the bottom of the trench excavations to a minimum of six inches above the crown of the pipe. Pipe bedding material should consist of crushed aggregate, clean sand or similar open-graded material. Proposed bedding and pipe zone materials should be reviewed by Geocon prior to construction; materials such as ¾-inch drain rock may require wrapping with filter fabric to mitigate the potential for piping. Bedding and backfill should also conform to the requirements of the governing utility agency.

6.7.3 Utility trenches backfilled with granular material (including pipe bedding material) may serve as conduits for groundwater and may cause pumping, seepage or other undesirable effects at the lower ends of trench lines. Consideration should be given to constructing “trench plugs” at periodic intervals along utility line alignments to reduce those potential problems. Trench plugs should be located where the utility trench enters the perimeter of a structural area. Trench plugs may consist of compacted native clay soil or concrete. Trench plug material should completely surround the pipe and be in contact with the undisturbed walls and bottom of the trench. The length of soil trench plugs should be on the order of one to two feet. The geotechnical engineer should review the placement and design of trench plugs prior to plan finalization.

6.8 Shallow Foundations

6.8.1 Foundations for the new buildings and ancillary site improvements may consist of continuous strip footings founded in competent formational materials and/or properly compacted fill. Over-excavations or other provisions may be required if loose or unstable soils or other unsuitable conditions are encountered during footing excavations. Columns supporting the planned canopies at the Barn and amphitheater may utilize drilled shafts for foundation support per the recommendations of Section

6.9. Barn, Amphitheater, Event Center Buildings and Minor Site Structures Continuous footings have a minimum embedment depth of 24 inches below lowest adjacent pad grade. The footings should be at least 12 inches wide. Perimeter footings for the new buildings should consist of continuous strip footings embedded at least 24 inches below lowest adjacent grade. Any spread footings should be at least 4 feet square and founded at least 24 inches below lowest adjacent pad grade and integral with strip footings.

Footings proportioned as recommended may be designed for an allowable soil bearing pressure of 2,500 pounds per square foot (psf). The allowable bearing pressure is for dead + live loads may be increased by up to one-third for transient loads due to wind or seismic forces.

The allowable passive pressure used to resist lateral movement of the footings may be assumed to be equal to a fluid weighing 250 pounds per cubic foot (pcf). The allowable coefficient of friction to resist sliding is 0.30 for concrete against soil. Combined passive resistance and friction may be utilized for design provided that the frictional resistance is reduced by 50%. Where not protected by flatwork or pavement, the upper 1 foot of soil should be neglected when calculating passive resistance to lateral loads
Minimum reinforcement for continuous footings should consist of four No. 5 steel reinforcing bars; two placed near the top of the footing and two near the bottom. Reinforcement for spread footings should be designed by the project structural engineer.

Wedding Pavilion
Continuous footings should be at least 12 inches wide with a minimum embedment depth of 18 inches below lowest adjacent pad grade. Perimeter footings for the structure should consist of a continuous strip footing. Any spread footings should be at least 4 feet square and founded at least 18 inches below lowest adjacent pad grade.

Footings proportioned as recommended may be designed for an allowable soil bearing pressure of 4,000 pounds per square foot (psf). The allowable bearing pressure is for dead + live loads may be increased by up to one-third for transient loads due to wind or seismic forces.

The allowable passive pressure used to resist lateral movement of the footings may be assumed to be equal to a fluid weighing 350 pounds per cubic foot (pcf). The allowable coefficient of friction to resist sliding is 0.35 for concrete against soil. Combined passive resistance and friction may be utilized for design provided that the frictional resistance is reduced by 50%. Where not protected by flatwork or pavement, the upper 1 foot of soil should be neglected when calculating passive resistance to lateral loads
Minimum reinforcement for continuous footings should consist of four No. 4 steel reinforcing bars; two placed near the top of the footing and two near the bottom. Reinforcement for spread footings should be designed by the project structural engineer.

6.8.2 Underground utilities running parallel to footings should not be constructed in the zone of influence of footings. The zone of influence may be taken to be the area beneath the footing and within a 1:1 plane extending out and down from the bottom edge of the footing.

6.8.3 The foundation subgrade should be sprinkled as necessary to maintain a moist condition without significant shrinkage cracks as would be expected in any concrete placement. Prior to placing rebar reinforcement, foundation excavations should be evaluated by our representatives for appropriate support characteristics and moisture content. Moisture conditioning may be required for the materials exposed at footing bottom, particularly if foundation excavations are left open for an extended period.

6.9 Drilled Shaft Foundations

6.9.1 Cast-in-place, straight shaft concrete piers may be used to support the planned canopies at the Barn and amphitheater. Drilled shaft foundations should have a minimum center-to-center spacing of at least three pier diameters. Pier embedment depths and reinforcing should be specified by the project structural engineer. Specific recommendations for the piers in each area are as follows.

Barn and Entry Canopy
Reinforced concrete piers should have a minimum diameter of 24 inches and minimum embedment depth of 5 feet. The upper 2 foot of soil should be neglected when calculating for vertical capacities.

Allowable skin friction to resist axial compression loads may be taken as 300 psf to a depth of 6 feet below pad grade, and 400 psf below a depth of 6 feet. For uplift capacity, allowable skin friction may be assumed to be ⅔ of that in compression. Piers extending at least 7 feet below pad grade may utilize an allowable end bearing pressure of 4,000 psf. End bearing and skin friction may be used in combination provided that skin friction contribution is ignored in the pier length equivalent to the pier diameter, measured from the bottom of the pier. End bearing contribution to axial capacity may be increased by ⅓ when considering transient wind or seismic loads.

Allowable passive pressure used to resist lateral movement may be assumed to be equal to a fluid weighing 300 pcf to a depth of 7 feet and 500 pcf below. Allowable passive pressure may be applied over two pier diameters. Where not protected by pavement, passive resistance should be ignored for the upper 1 foot of site soils.

Amphitheater
Reinforced concrete piers should have a minimum diameter of 24 inches and minimum embedment depth of 8 feet. The upper 2 foot of soil should be neglected when calculating for vertical capacities.

Allowable skin friction to resist axial compression loads may be taken as 300 psf. For uplift capacity, allowable skin friction may be assumed to be ⅔ of that in compression. End bearing contribution should be ignored.

Allowable passive pressure used to resist lateral movement may be assumed to be equal to a fluid weighing 300 pcf. Allowable passive pressure may be applied over two pier diameters. Where not protected by pavement, passive resistance should be ignored for the upper 1 foot of site soils.

6.9.2 Pier excavations should be clear of loose soil, debris, and standing water prior to placing reinforcing steel. Although not expected, temporary casings may be needed if caving conditions are encountered.

The geotechnical engineer (a representative of Geocon Consultants, Inc.) should continuously observe drilling operations and concrete placement for the piers.

6.10 Retaining Wall Design

6.10.1 Lateral earth pressures may be used in the design of permanent retaining walls and buried structures.

Lateral earth pressures against these facilities may be assumed to be equal to the pressure exerted by an equivalent fluid. The unit weight of the equivalent fluid depends on the design conditions. Table

6.10 summarizes the weights of the equivalent fluid based on the different design conditions.

Retaining wall and structure backfill should meet the requirements of Section 6.4.2.

TABLE 6.10

RECOMMENDED LATERAL EARTH PRESSURES
Condition Equivalent Fluid Density
Active 35 pcf
At-Rest 55 pcf

6.10.2 Unrestrained walls should be designed using the active case. Unrestrained walls are those that are allowed to rotate more than 0.01H (where H is the height of the wall). Walls restrained from movement such as basement walls or underground utility vaults should be designed using the at-rest case. The above soil pressures assume level backfill under drained conditions within an area bounded by the wall and a 1:1 plane extending upward from the base of the wall and no surcharges within that same area. Unless project-specific loading information is provided by the structural engineer, where typical vehicle loads are expected behind a retaining wall, an additional uniform surcharge pressure equivalent to 2 feet of backfill soil should be used for design.

6.10.3 Unless hydrostatic conditions are incorporated into design, retaining walls greater than 2 feet tall (retained height) should be provided with a drainage system adequate to prevent the buildup of hydrostatic forces and should be waterproofed as required by the project architect. Positive drainage for retaining walls should consist of a vertical layer of permeable material positioned between the retaining wall and the soil backfill. The permeable material may be composed of a composite drainage geosynthetic or a natural permeable material such as crushed gravel at least 12 inches thick and capped with at least 12 inches of native soil. A geosynthetic filter fabric should be placed between the gravel and the soil backfill. Provisions for removal of collected water should be provided for either system by installing a perforated drainage pipe along the bottom of the permeable material which leads to suitable drainage facilities.

6.10.4 We recommend that all retaining wall designs be reviewed by Geocon to confirm the incorporation of the recommendations provided herein. In particular, potential surcharges from adjacent structures and other improvements should be reviewed by Geocon.

6.11 Interior Concrete Slabs-on-Grade

6.11.1 Concrete slabs-on-grade subject to vehicle loading are considered pavements should be designed in accordance with the recommendations in Section 6.13 of this report.

6.11.2 Concrete slabs-on-grade for structures, not subject to vehicle loading, should be a minimum of 5 inches thick and minimum slab reinforcement should consist of No. 4 steel reinforcing bars placed 18 inches on center in both horizontal directions. Steel reinforcing should be positioned vertically near the slab midpoint.

6.11.3 Interior slabs should also be underlain by 3 inches of ½-inch or ¾-inch crushed rock with no more than 5 percent passing the No. 200 sieve to serve as a capillary break. The crushed rock should be subjected to several passes with a walk-behind vibratory compactor or similar equipment prior to placing a vapor barrier or rebar for the slab-on-grade.

6.11.4 The slab-on-grade dimensions and minimum reinforcement recommendations presented herein are based upon soil conditions only and are not intended to be used in lieu of those required for structural purposes.

6.11.5 Crack control joints for interior slabs-on-grade should be spaced at intervals not greater than 10 feet and should be constructed using saw-cuts or other methods as soon as practical following concrete placement. Crack control joints should extend a minimum depth of one-fourth the slab thickness.

Construction joints should be designed by the project structural engineer.

6.11.6 The recommendations of this report are intended to reduce the potential for cracking of slabs due to soil movement. However, even with the incorporation of the recommendations presented herein, foundations, stucco walls, and slabs-on-grade may exhibit some cracking due to soil movement. This is common for project areas that contain expansive soils since designing to eliminate potential soil movement is cost prohibitive. The occurrence of concrete shrinkage cracks is independent of the supporting soil characteristics. Their occurrence may be reduced and/or controlled by limiting the slump of the concrete, proper concrete placement and curing, and by the placement of crack control joints at periodic intervals, in particular, where re-entrant slab corners occur.

6.12 Moisture Protection Considerations

6.12.1 A vapor barrier is not required beneath slabs-on-grade for geotechnical purposes. Further, the migration of moisture through concrete slabs or moisture otherwise released from slabs is not a geotechnical issue. However, for the convenience of the owner, we are providing the following general suggestions for consideration by the owner, architect, structural engineer, and contractor. The suggested procedures may reduce the potential for moisture-related floor covering failures on concrete slabs-on-grade, but moisture problems may still occur even if the procedures are followed. If more detailed recommendations are desired, we recommend consulting a specialist in this field. If a vapor barrier is used beneath mat slab foundations, we should review the geotechnical design parameters presented herein.

6.12.2 A vapor barrier meeting ASTM E 1745-09 Class C requirements may be placed directly below the slab, without a sand cushion. To reduce the potential for punctures, a higher quality vapor barrier (15 mil, Class A or B) should be used. The vapor barrier, if used, should extend to the edges of the slab, and should be sealed at all seams and penetrations.

6.12.3 The concrete water/cement ratio should be as low as possible. The water/cement ratio should not exceed 0.45 for concrete placed directly on the vapor barrier. Midrange plasticizers could be used to facilitate concrete placement and workability.

6.12.4 Proper finishing, curing, and moisture vapor emission testing should be performed in accordance with the latest guidelines provided by the American Concrete Institute, Portland Cement Association, and ASTM.

6.13 Pavements

6.13.1 The upper 12 inches of pavement subgrade should be scarified, moisture conditioned to at least 2% above optimum and compacted to at least 95% relative compaction. Prior to placing aggregate base, the finished subgrade should be proof rolled with a laden water truck (or similar equipment with high contact pressure) to verify stability. Subgrade soils for the parking lot should be lime-treated per the recommendations in Section 6.5.

6.13.2 Sidewalk, curb and gutter, and driveway encroachments should be designed and constructed in accordance with City of Brentwood requirements, as applicable.

6.13.3 We recommend the following asphalt concrete (AC) pavement sections for design to establish subgrade elevations in pavement areas. The project civil engineer should determine the appropriate Traffic Index (TI) based on anticipated traffic conditions. The flexible pavement sections below are based on estimated design TIs. We can provide additional sections based on other TIs if necessary.

6.13.5 It should be understood that AB-surfaced pavement sections e.g. Alternatives #3 and #4 in Table 6.13 are relatively porous compared to AC-surfaced pavements and therefore have an inherently higher potential for surface infiltration and subsequent wetting of subgrade soils. As such, the potential for DocuSign Envelope ID: D1FF601A-44A8-44E4-9829-38B3059AE14B C.4.h

subgrade softening and/or swelling is higher where AB-surfaced pavement are used, especially where subgrade soils are not lime treated.

6.13.6 Unless specifically designed and evaluated by the project structural engineer, where concrete paving will be utilized for support of vehicles, we recommend the concrete be a minimum of 6 inches thick and reinforced with No. 4 steel reinforcing bars placed 18 inches on center in both horizontal directions. In addition, doweling, reinforcing steel or other load-transfer mechanism should be provided at joints if desired to reduce the potential for vertical offset. The concrete should have a minimum 28-day compressive strength of 3,500 psi. Where heavy concentrated loads such as forklift traffic is anticipated, the pavement thickness should be increased to 8 inches minimum.

6.13.7 We recommend that at least 12 inches of Class 2 Aggregate Base be used below rigid concrete pavements. The aggregate base should be compacted to at least 95% relative compaction near optimum moisture content.

6.13.8 In general, we recommend that concrete pavements be designed, constructed, and maintained in accordance with industry standards such as those provided by the American Concrete Pavement Association.

6.13.9 The performance of pavements is highly dependent upon providing positive surface drainage away from the edge of pavements. Ponding of water on or adjacent to the pavement will likely result in saturation of the subgrade materials and subsequent cracking, subsidence, and pavement distress.

If planters are planned adjacent to paving, we recommend the perimeter curb be extended at least 6 inches below the bottom of the aggregate base to minimize the introduction of water beneath the paving. Alternatives such as plastic moisture cut-offs or modified drop-inlets may also be considered.

6.13.10 Asphalt pavement section recommendations for driveways and parking areas are based on Caltrans design procedures. It should be noted that most rational pavement design procedures are based on projected street or highway traffic conditions and, hence, may not be representative of vehicular loading that occurs in parking lots and driveways. Pavement proximity to landscape irrigation, reduced traffic speed and short turning radii increase the potential for pavement distress to occur in parking lots even though the volume of traffic is significantly less than that of an adjacent street. The HDM indicates that the resulting pavement sections for parking lots are minimized to keep initial costs down but are reasonable because additional AC surfacing can be added later, if needed, and generally without incurring traffic hazards or traffic handling problems. It is generally not economically feasible to design and construct the entire parking lot and driveways for the unique loading conditions previously described. Periodic maintenance of the pavement in these areas, therefore, should be anticipated.

6.14 Exterior Slabs

6.14.1 Exterior slabs, not subject to traffic loads, should be at least 4 inches thick and reinforced with No. 4 steel reinforcing bars placed 18 inches on center in both horizontal directions, positioned near the slab midpoint. We recommend that at least 6 inches of Class 2 AB be used below exterior flatwork.

The aggregate base should be compacted to at least 95% relative compaction near optimum moisture content. Prior to placing AB, the subgrade should be moisture conditioned to at least 2% over optimum and properly compacted to at least 90% relative compaction. The AB layer may be omitted where subgrade soils are lime-treated per the recommendations herein.

6.14.2 A thickened edge should be provided at the perimeter of large exterior slab areas such as that planned at the Barn/Entry Canopy. The thickened edge should extend at least 12 inches below lowest adjacent compacted subgrade, which is at least 12 inches below the bottom of the AB layer underlying the slab, where applicable.

7. FURTHER GEOTECHNICAL SERVICES

7.1 Plan and Specification Review

7.1.1 We should review project plans and specifications prior to final design submittal to assess whether our recommendations have been properly implemented and evaluate if additional analysis and/or recommendations are required.

7.2 Testing and Observation Services

7.2.1 The recommendations provided in this report are based on the assumption that we will continue as Geotechnical Engineer of Record throughout the construction phase and provide compaction testing and observation services and foundation observations throughout the project. It is important to maintain continuity of geotechnical interpretation and confirm that field conditions encountered are similar to those anticipated during design. If we are not retained for these services, we cannot assume any responsibility for others interpretation of our recommendations, and therefore the future performance of the project.
