Report Summary
Phase: Earthwork
Type of Inspection / Service: Soil
Date: 08/28/2023
BSK Associates arrived on site for observation and testing of finish subgrade for over ex crane pad on North side of abutment #1 GBI grading contractor had worked on Sunday to bring grade up to finish. BSK had contractor pothole 1' down test location and also tested finish grade. BSK obtained relative compaction at the time of testing of 95% or greater. BSK notified contractor of finding.
BSK Associates then went to southern side of the bridge for observation and backfill testing of abutment #2. The contractor moisture conditioned native soils then used a excavator to place fill followed by a front vibrating sheepsfoot drum Hamm H101i compactor for compaction efforts. BSK took in place nuclear density tests obtaining relative compaction at the time of testing meeting project requirements.
Please see attached site plan for rough test locations and elevations.
BSK picked up 1 set of 5 concrete cylinders. Samples taken at end of the day to BSK Livermore Materials Laboratory for assigned testing.

AGREEMENT FOR GEOTECHINICAL/CONSTRUCTION MATERIALS TESTING SERVICES Construction Testing Services, Inc.
THIS AGREEMENT is made and entered into as of the _____ day of __________________, 20_____ by and between the City of Brentwood, a municipal corporation of the State of California ("City"), and Construction Testing Services, Inc., a California 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 because 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 DRAFT
2 PSA_PW_City Attorney Approved Version 053025
CA/Agmts/FTA/PSA/2022/087.1 – PSA Agmt Over $10K with PW.docx 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 from July 1, 2025 through June 30, 2026. The City Manager may amend the Agreement to extend it for two (2) additional one (1) year periods or parts thereof in an amount not to exceed two hundred thousand dollars ($200,000) 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 two hundred thousand dollars ($200,000) 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 because 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.

CA/Agmts/FTA/PSA/2022/087.1 – PSA Agmt Over $10K with PW.docx 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 their 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 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.

10.1.4 Professional Liability. Errors and omissions liability appropriate to Consultant’s profession with limits of not less than $1,000,000 per claim.
10.2 Endorsements.

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 will contain a waiver of subrogation for the benefit of City.
11. Business License. If required, 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. Consultant will allow inspection of all work, data, documents, proceedings, and activities related to the Agreement for a period of three (3) years from the date of final payment under 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 is terminated for any reason prior to completion of the Project and if under such circumstances City uses, DRAFT

Upon the contract award and the issuance of the first Task Order, CTS will initiate a Pre-Construction Meeting with project stakeholders. This meeting serves as a platform to forge strong relationships between CTS and the entire project team and there the project’s goals, scope, and schedule, are determined. By clarifying roles and expectations upfront, information that CTS needs to plan its services effectively is pulled into the conversation and considered. The groundwork is thus laid for a streamlined and effective investigation and inspection process; and the agility and efficiency of the entire project team is enhanced.
CTS acknowledges that project schedules evolve. The rapport established through the pre-construction meeting and regularly scheduled check-ins will facilitate the seamless dissemination of schedule changes and allow CTS to accommodate adjustments swiftly and effectively which in turn will minimize disruptions and maintain project momentum.
Methodology of Service:
Daily Field Reports: Our inspectors digitally submit daily field reports using ELAS and can send digital copies (PDF) to any interested party as required. This report is reviewed by the CTS Engineering Team on the same day.
Weekly Summary Reports: Our reporting software ELAS compiles all lab test results and field/shop inspections performed during the week and generates a summary of all work done. These are reviewed by the Operations and Engineering teams before being finalized and 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.
Immediate Response: Any outstanding issues are punch-listed and reported immediately to the client for resolution. Our inspectors are equipped with the tools needed to accomplish the desired test or inspection.
Samples are picked up and transported in accordance with applicable ASTM standards to our local laboratory for further analysis and testing.
Laboratory Results: CTS can turn around reports and laboratory results in 24 to 48 hours, depending on when the sample is received by our laboratory. CTS runs a double shift, meaning there is someone available to run your lab test 15 hours per day. Typed laboratory testing reports are distributed the following week from the day the laboratory test was performed. Sub-standard results are immediately communicated to the proper team members, as well as the owner. Real-time lab results are also posted online using ELAS.
Dispatch: Our inspectors are available with a minimum of 24 hours’ notice. The project manager and/or superintendent may contact our dispatcher to schedule inspections and/or sample pick-ups. Upon receipt of an inspection request, our qualified inspectors will perform the inspection(s) as per approved standards accordingly.
Budget Tracking: Our budget analyses are provided monthly using ELAS. Your project manager will analyze invoices against summary reports so that they and you will always know where your project stands. As the project progresses there might be some changes or additions to the budget which will be listed in the lower “additional services” section of the budget analysis.

5. Quality of Work
Electronic Reporting System – ELAS:
CTS has created a cloud-based application and companion app called ELAS that optimizes the reporting process.
ELAS as a tool facilitates transparency with CTS activities, enabling Clients to view inspector activity, reports, and preliminary estimates. In addition to test-result reporting capabilities, ELAS has tools for project managers to immediately generate budgets based on initial estimates and work performed. Full-color reports with pictures and plan markups are available in real-time for review by our engineers and, ultimately, distribution to project shareholders. Our team uploads inspection and laboratory reports daily, and ELAS allows these reports to be immediately emailed to the project team at the click of a button.
In addition, ELAS tracks exceptions and non-compliance incidents from initiation to closure.
ELAS brings efficiencies to every sector of CTS, improves the Client relationship, and keeps joint projects on track. Let our investment work for you! Scan this QR code to learn more.

Proposal No. 25-0520
City of Brentwood, Engineering Department
Attention: Vatsal Patel
150 City Park Way, Brentwood, CA 94513
RE: Statement of Qualifications to Provide Geotechnical/Construction Materials Testing Services for Infrastructure Projects Dear Vatsal,
The City of Brentwood (City) seeks qualified firms to provide geotechnical, construction materials testing, and related services for upcoming projects. Twining, Inc. (Twining) understands up to four firms will be selected for an initial one-year term, with the potential for two one-year extensions, and all services must comply with strict Caltrans testing requirements and City standards. Additionally, Twining brings the following value to this contract:
Taylor Latimer will serve as our Project Manager and single point-of-contact for the City: Twining has identified the City as a high priority agency, and as such, Taylor will prioritize the City's projects and be prepared for any requested support at a moment's notice.
Taylor will be supported by our large staff of in-house materials engineers, geotechnical engineers, civil engineers, geologists, multicarded inspectors, and ASNT Level III experts. Having this level of in-house experts on our team means we can be proactive with potential project challenges and provide possible solutions before they become issues. As a material testing and inspection firm, this makes Twining a one-stop shop for all of the City’s geotechnical engineering, special inspection and material testing needs.
Geotechnical Engineering and Materials Testing Expertise: Twining performs all of the necessary geotechnical testing in-house using local staff. All personnel proposed for use on this project are Twining employees that have longevity with Twining. Our engineers and project managers personally know each of our soil and lab technicians and we communicate with field and lab personnel regularly, including periodic in-house training sessions.

Mokelumne Bicycle and Pedestrian Overcrossing Project
The Mokelumne Trail Bicycle and Pedestrian Overcrossing is an 850-foot-long bridge spanning Highway 4 in Brentwood, reconnecting trail segments separated by the highway’s expansion. The bridge features a 16-foot-wide pathway, designed to accommodate both cyclists and pedestrians while complying with ADA standards.
Built with a multi-span design and a central support column in the highway median, the bridge sits on earthen embankment approaches. Its width also allows for potential future autonomous shuttle travel. Completed in March 2024 at a cost of approximately $13 million, the project was funded through Measure J taxpayer dollars, the State Route 4 Bypass Authority, and Bay Area Toll Authority bridge toll funds.
Twining provided comprehensive materials testing and inspection services to ensure the bridge’s safety, durability, and performance. During pre-construction, Twining collaborated with the project team on submittal reviews, pre-construction meetings, and planning. Throughout construction, inspectors oversaw earthwork, asphalt, and concrete operations, conducting field density testing, verifying compaction, and analyzing material samples in the laboratory. Through thorough QA documentation and coordination, Twining supported the successful delivery of this vital infrastructure, enhancing safe and efficient connectivity for cyclists and pedestrians.

4. Project Approach
4.a. Overall Project Approach
The following is our approach for managing materials testing tasks in support of projects under the City’s on-call contract:
Overcoming On-Call Contract Challenges. Twining’s personnel depth of over 180 inspectors, allows us to ensure that the City’s project will have highly trained and appropriately certified inspection personnel. Twining consistently supplies multi-certified, qualified inspectors with extensive experience to each project, providing efficiency and effective performance, while conducting multiple inspections in compliance with regulations. We recognize the importance of efficiency and the sensitivity of budgets. Hence, we maintain rigorous budget reporting and tracking that enables clients the ability to track their budget daily and weekly. Additionally, reports are published to an online document storage site called ConstructionHive. All project reports are accessible to the City even after the project has been archived. The system also allows Twining to track the hours worked, non-compliant items, clearing of non-compliant items, and more.
Permitting Challenges. For over five decades, Twining has been well-versed in applying for and obtaining all necessary permitting to complete geotechnical field investigations. We understand, that for projects under this contract, wells and soil borings within the County of Contra Costa will require permits from Environmental Health. We are familiar with the County's Land Use Program that issues permits for wells and soil borings and will conduct necessary inspections during drilling. Twining will handle all permitting efforts in-house including projects that includes work impacting the public right-of-way (ROW), requiring an Encroachment Permit from the City.
Your Project
Manager, Taylor
Latimer, will review
the available plans
and
specifications for
the project.
1 The project
technician/
inspector performs
the appropriate
testing or inspection, and logs location of each test or item inspected.
When required,
samples are
obtained from
construction
materials for
further lab testing.
3 If a material type
(e.g. ready-mixed
concrete) requires
plant inspection,
both the plant and
field technicians
will communicate
directly with the
Project Manager
regarding batched
quantities, time
of shipment, total
yards at the plant,
plant break downs,
and all pertinent
daily activities.
5 Upon dispatch
request from City
representative,
the appropriate
inspector with the
required certifications is assigned
to the project.
These technicians
and inspectors are
available within
24 hours of this
request and often
can be provided
with even less prior
notification.
2 The technician/
inspector logs
their daily testing,
inspection, and
sampling and
provides a copy of
their daily report to
the City's
representative for
their signature.
The daily report
also contains a
log of their hours
covering the duties
performed that day.
4 Daily field and
shop reports are
reviewed by the
Taylor, along with
all laboratory test
results, and
distributed
weekly to the
project team. A log
of all tests and inspections is kept by
Taylor, which also
includes tracking
and resolution of
any noncompliant items.
6 We will prepare a final construction QA
report to document
the results of all
required testing and
recommendations.
This report will be
available for review
and comment by
City staff within
seven business
days from the completion of site work.
The final report will
be submitted to
the City within five
business days.
