SUBJECT: REQUEST FOR PROPOSAL FOR ON-CALL GEOTECHNICAL SERVICES 2022 Dear Mr. Uphus,
Geocon West, Inc. (Geocon) welcomes the opportunity to continue to support the City of Garden Grove (City) in reference to the RFP for On-Call Geotechnical Services. Over the course of the last 3 years as an on-call consultant to the City, we have demonstrated our technical expertise, project management approach, integrity, and responsiveness. In that time, we have also come to know what the City expects in a consultant, familiarized ourselves with City processes, approaches to project delivery, and procurement standards. We stand ready to continue to serve the City and its staff by providing expert geotechnical and materials testing services while using our working knowledge of the City's programming to enable optimal project execution from Notice to Proceed to Project Closeout.

Geocon has over 50 years of experience performing geotechnical services for public agencies and municipalities right here in Southern California. We also perform engineering geology, materials testing and inspection, and environmental engineering services. Our local office and certified laboratory in Irvine will manage this contract and partner with the City to provide Geotechnical Services, which will include, but are not limited to: performing subsurface exploration and analysis; required laboratory testing; reviewing existing geotechnical/geologic maps, reports or other documents related to the project and its location; reviewing project plans and specifications through the design process, with consideration of geotechnical issues; providing geotechnical evaluation and recommendations; investigating and analyzing existing pavement conditions; preparing and submitting final geotechnical reports with logs of exploratory borings, results of laboratory testing and analysis; and performing asphalt batch plant inspections.

We have performed the same services for similar projects for numerous public agencies across our 52-year history, including recently for the City of Anaheim, the City of Newport Beach, and the County of Los Angeles, Department of Public Works, to name a few.

Beyond our extensive experience and demonstrated service to the City, what sets Geocon apart? ✓ We bring innovation and problem-solving to all of our projects-big or small. Our goal on every project is to develop creative, cost-effective, and practical geotechnical and environmental solutions. Problem-solving early in project phasing is key. We pride ourselves on adding genuine value to every aspect of a project to enable the project to successfully move across phases.
✓ Transparency is key to our project management approach. We are committed to keeping cost, schedule, quality, safety, and importantly, transparency, top of mind while we deliver our Task Orders. We maintain strict burn-rate reports internally so that we stay on budget and transparently communicate our project milestone tracking to clients. Drawing from our extensive experience, we understand the need for rapid response times, communication and coordination with the project team, while maintaining excellent standards and providing quality deliverables. ✓ Our principals are working principals. Senior engineers and principals, like myself, will service your Task Orders. You will find a highly experienced leadership team at your disposal. Additionally, our principals play a direct role in 2807 McGaw Avenue■ Irvine, CA 92614 ■ Telephone (9491 491-6570 ■ [email protected]

oversight of the team and take every opportunity to streamline costs. For example, our principals bill at senior rates to control costs. We also have many multi-certified inspectors, and it is always our goal to have one inspector cover multiple tasks rather than having two or more inspectors on-site simultaneously; this minimizes the assignment of multiple field staff, all per the direction of working principals. ✓ Our team is local, experienced, and available. Geocon offers an experienced, local team you can trust for this on­ call contract. We are known for our responsiveness and availability to meet short-term requests. We do not utilize pay-when-paid clauses, so we receive priority scheduling from our subcontractors to expedite your projects. Our fully operational office and comprehensive testing laboratory in Irvine as well as our staff of engineers, geologists, technicians, and inspectors stand ready to serve the City. ✓ we perform our soils and materials testing In our in-house laboratories. We perform our services in-house, manage our own laboratories and maintain strict oversight of standards within our laboratories. We are consistently rated by CCRL and other certifying bodies with top performance for overall organization and accuracy of testing. our laboratories are certified by DSA, AASHTO/ AM RL, Ca ltra ns, and CCRL and can provide both soil and materials testing services 24 hours a day, 7 days a week. With staggered lab staff schedules, we are able to complete critical path testing much quicker than a typical lab.

As managing partner of Geocon West, Inc., I attest by my signature that I have the official authority to bind the company to commit its resources to fulfill the terms of this contract, and that this proposal will be valid for a minimum of 90 days. I manage the Irvine team, will manage all work under this contract, if awarded, and will be your point of contact. Please find my contact information below.

Geocon appreciates the opportunity to submit this proposal to the City. If awarded, we will be dedicated to every Task Order and ensure that we stand by our industry reputation for excellent customer service. Thank you for your consideration.

Sincerely,

0 UNDERSTANDING AND APPROACH

UNDERSTANDING
City of Garden Grove
On-Call Geotechnical Services
The City of Garden Grove is seeking proposals from qualified Consultants to provide On-Call Geotechnical Services for future Public Works projects. Geocon has thoroughly reviewed the contents of the City's RFP and understands that the City wishes to select consultants for on-call services for a period of three years. The Garden Grove Department of Public Works develops, operates, maintains, and upgrades the City's infrastructure. The public works projects anticipated to need geotechnical services are primarily capital improvement projects for transportation, storm drains, sewer, and water supply.

The scope of anticipated services is anticipated to include performing geotechnical investigations, pavement investigations, pavement condition surveys, pavement rehabilitation design; performing review of project plans and specifications; and providing construction inspection, materials testing, and laboratory testing services in conformance with the City's and/or Caltrans' Quality Assurance Program. Geocon is capable of providing the full scope of services outlined within the 17 bullet points listed on pages 2 and 3 of the City's RFP.

APPROACH
Geocon's first priority when presented with a scope of work for a project is to review the information provided as well as any background information available to gain a thorough understanding of the project elements, needs and potential challenges. Geocon will apply our project management style and approach that we have successfully developed for past and current on•call contracts with public agencies. Through the duration of the contract, Ms.

Adams will be the project manager and single point of contact for the City of Garden Grove. Our approach to geotechnical services is described in the following sections.

Geocon will furnish the necessary field equipment, survey equipment, and other supporting equipment and consumables. Our staff possesses a strong ability to provide diverse professional expertise in our service disciplines and through multi-certified personnel we will provide any or all services as applicable to this service category as outlined in the RFP.
• Consult with authorized employees, agents and representatives of the City and other agencies having jurisdiction relative to the geotechnical/materials testing and inspection of the project. Geocon is accustomed to managing projects under public works process where a multi-level jurisdiction takes place.

Geocon communicates with each team member and maintains a transparent communication pattern. • Attend meetings as scheduled by the City for the purpose of obtaining data pertaining to the project.

Geocon works well with members of the project team, and we make every effort to contribute innovative approaches to project designs which save our clients time and money. • Obtain and test soil samples. Prepare and submit preliminary geotechnical investigation and recommendations prior to the beginning of construction. Geocon will schedule an appropriate time to arrive on site with a drill rig to obtain soil samples at appropriate depths for each assigned project. Geocon will prepare a geotechnical investigation report which will detail our findings, recommendations, and conclusions, giving the City plenty of time to review and consult prior to construction. • Provide geotechnical/materials/ testing and/or inspection services during the construction of the project.

By providing a multi-certified inspector on site during construction, Geocon will save the City time and budgetary funding.
• Test designated construction materials for compliance with project plans and specifications. Geocon will provide materials testing through our accredited in-house quality assurance testing laboratory.

GEOJ:;ON -------·-----·-·-·--·---·--·-----·-----------------· ------··---··----------- • We will verify that the person requesting the inspection is the City's Construction Manager or has been authorized by the Construction Manager to request the inspection. Once the information has been verified, our dispatcher will schedule the inspection with an appropriate inspector. • On the day the inspection request was scheduled, Geocon's Inspector will meet the City's Construction Manager on-site to verify the type and location of inspection needed. • Inspections will be performed in accordance with project specifications and City requirements. • The inspector will provide daily written reports of inspection indicating compliance or non-compliance, which are to be signed by the City's Construction Manager before the inspector leaves the project site each day. The reports will include information about the inspector's arrival and departure time and very specific details about activities being performed each day. • The inspector will obtain samples, as required, and transport them to our in-house laboratory for testing and analysis. Material strength verification reports will be presented to the Construction Manager via email or fax the same day strength verification breaks are performed. • Laboratory test results will be provided promptly and in accordance with the agreed upon schedule to ensure quick review and reaction times from City and Geocon personnel.

Geocon will only acknowledge inspection requests from the Construction Manager or designated representative.

When called for inspection, Geocon inspectors will first check in with the Construction Manager upon arrival at the jobsite. All project activities will be documented daily on field reports indicating whether or not the construction work and materials testing was performed was in accordance with project requirements. Any problems will be reported immediately to the Construction Manager. Copies of material delivery tickets will also be collected and maintained. The daily field reports prepared by Geocon will be signed by the Construction Manager prior to Geocon leaving the jobsite. One copy of each field report will remain at the jobsite. All material samples will be properly labeled with the project name, date the sample was collected, and sampling location.

Samples will either be temporarily stored on-site in an approved location or immediately be transported to our soils and materials testing laboratory for testing and analysis.

Inspection and testing services will be performed by soils technicians, deputy inspectors, and special inspectors as required. In order to be as cost-effective as possible, it is our intent to provide simultaneous inspections and testing services for different disciplines (geotechnical/deputy/special inspections) with a single, highly qualified inspector, eliminating the need for a second inspector whenever possible. The selected inspector will be equipped with a vehicle and sufficient field-testing equipment (including a nuclear density gauge) to collect samples and provide in-place density test results in the field. A Deputy or Special Inspector will be provided for oversight and inspection as required. Field reports will be prepared and submitted on a daily basis and will be reviewed by Ms. Adams. Copies of all daily inspection reports and other required documents will be submitted with each invoice and copies of all documents will be maintained in electronic format (pdf) for emailing at any time.

COMPANY OWNERSHIP
Geocon West, Inc. (Geocon) is a California corporation established in 2003 as a professional engineering consulting firm providing comprehensive geotechnical, geologic, construction inspection, and environmental engineering and consulting services. In addition to these services, we also provide environmental remediation contracting (cleanup) services and operate soils and materials testing laboratories.

Geocon West, Inc. and its sister companies have nine regional offices that are located throughout California so that Geocon is well­ positioned geographically to promptly, efficiently, and cost effectively service its clients' needs. We employ a staff of over 300 technically strong, highly motivated engineers, geologists, environmental scientists, technicians, and special inspectors. Our managing principals are practicing professional geologists or engineers who actively manage projects and assign and mentor technical staff. Each office is supported by state-of-the-art inventories of field equipment and instrumentation, comprehensive technical libraries, and modern data-management systems.

Laboratory testing services are performed in an in-house soils and materials testing laboratory accredited by the American Association of State Highway and Transportation Officials (AASHTO), State of California Department of Transportation (Caltrans), Cement and Concrete Reference Laboratory (CCRL), Division of State Architect (DSA), and City of Los Angeles.

The average professional staff member has more than 10 years of experience at Geocon alone and has sufficient training and experience to respond to accelerated schedules without
encountering procedural problems or sacrificing the quality of work products. Our friendly company culture promotes excellent working relationships with our clients, and many clients have said that we function much like their own employees: a direct extension of their team.

Geocon performed a limited geotechnical investigation as part of the Acacia-Josephine Storm Drain Project for our on-call contract with the City of Garden Grove. The project was to improve the street pavement, which had rutting and cracks, as well as adding a storm drain to improve poor drainage conditions. The planned rehabilitation is meant to extend the roadway to meet a 20-year design life. During the investigation we performed a site reconnaissance, a visual evaluation of the existing pavement conditions, coring of the existing pavement, advancing borings, sampling the subgrade soils and groundwater, laboratory testing, and engineering analysis.

Geocon found that the roadways showed signs of moderate to severe distress, potholes, and raveling. Our reconnaissance observed streets that had ponded water, likely due to poor drainage. Geocon's opinion was that the construction of the proposed improvements could be performed provided their recommendations were followed and implemented during construction.

VARIOUS RESIDENTIAL AND ARTERIAL STREETS IMPROVEMENTS PROJECTS Geocon provided testing and observation services during the street improvement project in the City of Garden Grove. The project would result in an improved roadway surface and minimize maintenance efforts. The purpose of the testing and observations was to determine that the specifications required for the project were met. We performed in-place density tests, laboratory tests, and prepared a report summarizing our testing and observation findings. Geocon concluded that the preparation of the paving subgrade soils, and the placement of engineered materials had been performed in substantial conformance with the requirements of the City of Garden Grove and the project plans.

UTILITY POTHOLING
Geocon performed potholing services for the Acacia-Josephine Storm Drain project in the City of Garden Grove.

The purpose of the work was to obtain the size and type of pipe, measure the depth of cover from finished grade to the top of pipe; and measure horizontal control from centerline of the streets. After the utilities were exposed and the desired measurements obtained the surface was restored with asphalt or concrete.

care, and other care services to change and improve their future.

The project included challenging geotechnical conditions including soft, saturated shallow soils that are prone to excessive settlements under the application of building loads, as well as deeper soils that are susceptible to liquefaction under seismic loading. Based on these conditions, it was determined that the most efficient foundation system consists of a concrete mat foundation system deriving support in a blanket of engineered fill reinforced with geosynthetic materials spaced at approximately 18-inch intervals vertically. The geosynthetic reinforced engineered fill layer provides a flexible substratum which will reduce the propagation of settlements due to the underlying compressible soils and liquefiable soils to the foundation level.

Geocon currently holds a two-year on-call contract with the City of San Juan Capistrano for Geotechnical Review/Design and Materials Testing Services. Some of the projects we have provided services on are as follows:

GEOTECHNICAL THIRD-PARTY REVIEW FOR COMPASS ENERGY STORAGE At the request of the City of San Juan Capistrano, Geocon completed a third-party review of the Geotechnical Investigation Report for the proposed Compass Energy Storage project. The project consists of a battery storage yard, a project substation, an SDG&E interconnection switchyard, and a high voltage transmission line. With the exception of the transmission line, the proposed improvements will be located on 15.5 acres of a larger 58-acre parcel within the City of San Juan Capistrano. The project geotechnical challenges included areas mapped as having the potential for seismic slope instability, liquefiable materials, and proximity to an existing creek.

GEOTECHNICAL THIRD-PARTY REVIEW FOR PROPOSED NEW RESIDENCE Geocon has completed multiple third-party reviews of Geotechnical Reports prepared for proposed single-family residences on behalf of the City of San Juan Capistrano from a geotechnical perspective for compliance with applicable codes, guidelines, and standards of practice. Projects have ranged from relatively simple vacant lots with favorable geologic conditions to proposed hillside construction of undeveloped land with adversely oriented bedrock structure which requires slope stability analyses.

GEOTECHNICAL THIRD-PARTY REVIEW FOR PROPOSED APARTMENT UNITS At the request of the City of San Juan Capistrano, Geocon completed a third-party review of a Geotechnical Investigation for two new apartment units and the addition of a second story to an existing unit. Geocon completed this review on behalf of the City of San Juan Capistrano from a geotechnical perspective for compliance with applicable codes, guidelines, and standards of practice.
