Proposal No. 18-1204 Geo-Advantec, Inc. Page 1 of 7 December 20, 2018 Appendix “E”-Additional Relevant Information

B. Field Exploratory Works Phase Layout and footprint area of the proposed developments are defining factors in preparation of field exploratory program. Selecting a proper boring layout and pre-determination of boring depths and the types of drilling methods and sampling to be used in each project highly depends on the experience of the geotechnical engineer and the project specifics. To prepare and conduct the most appropriate field exploratory program for the City, we propose the following steps: 1. Review any other available documents such as previously prepared soils report (if any) for the site 2. Prepare boring layout and boring/sampling schedule based on the information collected from the above-mentioned steps, 3. Prepare time schedule for field drilling and/or field operations for percolation tests and coordinate the drilling days/times with the City to avoid any conflict with the City’s daily and regular operations. 4. Provide traffic control as required by the City 5. Perform field drilling and sampling C. Laboratory Testing and Office Engineering Phase The final determination of type of laboratory tests to be performed, will be based on the encountered soils, the laboratory tests may include some or all the followings: Gradation, Moisture & Density, Atterberg Limits, Direct Shear, Consolidation, Unconfined Compression, R-Value, Expansivity and Corrosivity (Sulfate, Chloride, PH) The office engineering tasks may vary for different types of projects, but in general are comprised of: 1. Evaluating geology characters of the site 2. Performing site-specific geohazard evaluation 3. Analyzing field and laboratory data 4. Analyzing and evaluating effect of geotechnical hazards at the site, for the specific project liquefaction potential at the site 5. Conducting seismic hazard study to obtain seismic coefficients according to CBC regulations 6. Evaluating and reporting other potential geological hazards at the site 7. Slope stability and liquefaction hazards evaluation 8. Pavement study/evaluation and recommendations (for pavement projects) 9. Evaluating different foundation systems to carry the introduced loads including shallow footings and CIDH shafts (bearing capacity and settlement evaluation) for structures D. Final Report Phase In general, the final geotechnical report, as a minimum, will include: 1. A site plan showing the location of borings 2. A discussion of geotechnical condition of the site within the project area 3. A discussion of geological condition of the site 4. A discussion of the materials encountered in the borings and their engineering properties

Our cost estimates are based on our vast experience in geotechnical engineering in Southern California. All the reimbursable and overhead costs are included in our proposed fee and there will be no extra or hidden cost for the project. Our Quality Control (QC) procedure for the geotechnical engineering investigation projects includes: • Clarifying and entering QC issues into our customized project management programs/logs prior to beginning of project • Reviewing the site plan in conjunction with the type of structure, range of anticipated structural loads and the site general geology and available geo-hazard information • Preparation of boring layout and drilling/sampling schedule for the field engineer and drilling crew. This task will be done by the project manager who is the geotechnical engineer in charge of the project • Performing field exploratory work and field logging under supervision of a registered engineer/geologist; • Logging all laboratory samples into our QC system when they are brought in. The responsible geotechnical engineer is consulted for priority or questions on specific test methods to ensure tests are performed per the correct standards • Reviewing field boring logs vs. the obtained physical samples and the laboratory test results, and finalizing the boring logs • Reviewing all the engineering calculations, analyses and reports prepared by our engineering staff, by our principal and senior professional(s) on the project

• Reviewing all the engineering recommendations and designed alternatives/solutions for different parts of the project considering their practicality, compatibility with applicable codes, and time and cost impact on the project • Overseeing the project schedule in a timely manner, to assure the satisfactory progress of the tasks and coordinating necessary progress meetings with the City’s representative, to meet the project’s schedule

5.1.2.2. Approach to Soils/Grading Monitoring, and Testing/Inspection Services The key elements to our success in performing and delivering our services are: • Assigning a full-time project manager, who will be the only point of contact • Our project management skills • Technical Approach for monitoring, testing and inspection services • Scheduling and time control • Budget Control • Quality Control The above-mentioned key elements will be discussed in more detail in the forthcoming sections. A. Project Management Based on our key members’ extensive experience in conducting geotechnical and geo-hazard investigations, as well as field inspection and testing for projects of similar size and type, we are confident that we will be able to provide the best possible services, which will satisfy the client’s needs. To accomplish our goal and deliver the level of service that fulfills client’s intents, we assign a full- time field operation manager (Project Manager) for this project, who will be the fully authorized person of our company and the only point of contact for the client. Our proposed Project Manager (PM), Mr. Matin Noorzay will be deeply involved in all facets of the project. He will supervise all the field testing and inspection works and if become necessary, he will attend all the City meetings to assure the quality performance of all the inspection and testing activities in the field and laboratory meets the highest level of standards and satisfies the client’s needs. The followings are the key elements of our managerial approach which enable us to respond properly to the client and for this specific project: • Availability of the PM in a 24/7 manner • Effective communication between the PM and the City assigned representative for this project • Tracking the schedule by following up the tasks on a daily basis and conducting weekly/as needed progress meetings with the client (if needed) • QA/QC program, as explained later B. Technical Approach Our field supervisor will perform supervision and coordination of all field and laboratory services. Our clerical staff will assist in maintaining a high level of quality assurance in preparation of reports, presenting test results, and distributing the inspection and test reports. Our proposed testing and inspection services for construction phase of the projects include, but are not limited, to the following list: • Review plans, reports, and project specifications • Attend pre-construction and progress meetings (if needed) • Observe the bottom of excavations (for grading works)

Proposal No. 18-1204 Geo-Advantec, Inc. Page 4 of 7 December 20, 2018 Appendix “E”-Additional Relevant Information

Quality Control/Quality Assurance (QC/QA) Plan The main components of a successful management for a project include: • Budget Control • Time Control/Schedule tracking • Quality control on the materials and workmanship, to assure the completed works’ compliance with the project specifications and documents C.1. Budget Controlling and Resource Management: Budgeting for inspection and testing projects with sufficient accuracy is a challenge. Our services are based on the request/calls we receive from the project/City inspector. The need for our inspectors’ presence at the site is generally affected/controlled by the following factors: • Quantity of the construction item, e.g. total volume of concrete, volume of welding, etc. • Requirements outlined in the Testing & and Inspection program and the project documents, e.g. periodic, continuous, etc. • Contractor and sub-contractor’s efficiency and sequencing of events • Unexpected subsurface conditions for grading works • Weather conditions and other unforeseen delays To better manage the resources and control the budget, we will take the following steps: 1. We record all the inspections times and testing fees that are because of re-tests, non-compliances, and contractor’s deficient works. These recorded times and costs will be reported to the client on a monthly basis. 2. In all possible occasions, we will use/assign multi-certified inspectors to the jobs. This may help to save money for the client. 3. A budget review sheet will be submitted to the client on a monthly basis. The sheet will depict the amount/percentage of consumed budget versus the progress made per the schedule.

4. When about 75% of the budget is consumed, we will request to have a meeting with the client/client’s representative, to evaluate the budget consumption vs. the time schedule and progress made to date by the contractor, and plan for future works or to come up with a realistic supplementary budget for the remaining part of the work, if needed. In addition to propose a very competitive fee for projects, to help decrease the projects’ cost, we will use inspectors with multiple certifications. Our services for all during construction inspection and testing services will be on on-call basis. No travel time and mileage will be charged for the field inspection services. C.2. Schedule (Time Control): As for construction projects, GAI will work in full compliance with the project approved schedule. To respond to tight schedules, we can assign more inspectors to projects. GAI will be able to cover swing and night shifts for all projects where need may arise. For investigation projects, we furnish a specific schedule for each project. The schedule will be managed in house by using project management tools such as Excel logs and spreadsheets and different project management software such as P3, or Microsoft Project. The schedule will also be discussed with the City representative on a regular basis, so that all parties remain informed of the project progress. The specific dates of on-site activities/drillings will be addressed on the schedule and will be reviewed with the City before commencement of the work. The schedule will include phasing milestones which enables City to monitor and measure the progress of the project, as well as the logical sequence of tasks and durations. C.3. Quality Control (QC): the procedure for the field inspection and testing tasks, will include the followings: • Holding a kick-off meeting between the project manager, filed inspectors assigned to the projects and the City inspector/representative, to review the scopes and project specifics, • Performing a QC review on all the daily inspection reports by the field supervisor • Logging all non-compliances and reporting to the City on a weekly basis • Entering the samples into our laboratory logging/tracking system • Reviewing of the laboratory test results by the project engineer and distribute the results to the team/city • Maintain proper/necessary calibration on the field and laboratory testing equipment • Preparing of a final inspection and testing report as a part of close out documents 5.2.
