EARTH SYSTEMS I SOQTO PROVIDE ON-CALL MATERIALS TESTING SERVICES I MAY 23, 2023 1 CITY OF LA QUINTA With decades of experience in the local area, Earth Systems offers extensive experience and detailed knowledge and detailed knowledge of soil, groundwater, and geologic conditions in this region. We have conducted numerous geotechnical investigations and geologic studies for projects ranging from minor infrastructure to large-scale new construction of public works projects. With a local office and full-service materials testing laboratory in Bermuda Dunes, we are available to provide rapid response to requests for services, which can be essential for on-call contracts where projects may have short design and construction timeframes. As this is an on-call contract, scopes and project approaches will vary depending upon the needs of the City and the project. The following are brief descriptions of the types of services that we envision under this contract, and Earth Systems' general approach to each. GEOTECHNICAL FEASIBILITY STUDIES When a property is under consideration for a project, a geotechnical study can be invaluable to assess conditions that may affect the desired use of the site. Studies may include geologic research, review of aerial photographs and possibly limited subsurface exploration to identify potential geologic constraints, infiltrometer testing to determine suitability for on-site storm water retention or detention, or percolation tests to determine suitability for on-site effluent disposal. Such studies allow for informed decision making before investing further in a particular site. GEOTECHNICAL ENGINEERING INVESTIGATIONS Geotechnical engineering investigations are design -level studies intended to provide sufficient data and criteria to allow design of the project and meet jurisdictional requirements. To evaluate subsurface conditions, typically a series of borings are drilled to depths of interest, which will vary based upon the type of project, the grading concept, and the anticipated subsurface profile. Borings may be drilled using hollow -stem auger techniques or using Cone Penetrometer methods. For hollow stem borings, standard penetration tests are typically performed (ASTM D 1586) and soil samples are obtained using a ring -lined barrel sampler (ASTM D 3550). Bulk soil samples are also obtained from the auger cuttings. EARTH SYSTEMS I SOQTO PROVIDE ON-CALL MATERIALS TESTING SERVICES I MAY 23, 2023 1 CITY OF LA QUINTA 6 .i'�� ..fit.• - Prior to initiating any subsurface exploration, Earth Systems coordinates with Underground Service Alert (USA) for underground utility coordination and determination of the locations of other subsurface features that could potentially be impacted by drilling operations. Soil samples are tested in the laboratory to determine a variety of soil properties, depending upon the type of project, the proposed development concept, and the materials encountered. Such tests as unit weight and moisture, plasticity index, grain size determination, maximum density versus optimum moisture, expansion index, one-dimensional consolidation, angle of shearing resistance, R -value, and unconfined compressive strength may be performed. All laboratory testing is performed in our accredited laboratories by trained technicians and according to ASTM or other applicable standards. The field and laboratory data are reviewed by a Registered Geotechnical Engineer and/or a Certified Engineering Geologist and evaluated with respect to development of geotechnical criteria for the proposed project. Geotechnical engineering investigations and reports comply with the requirements of Sections 1803.1 through 1803.6 and J104.3 of the applicable edition of California Building Code (CBC). Geotechnical engineering investigations are supervised by qualified and experience geotechnical professionals who develop programs for subsurface exploration, laboratory analysis, and data evaluation. GEOLOGIC HAZARD STUDIES Projects involving a geologic scope are supervised by a Certified Engineering Geologist. These may be stand-alone reports or may be incorporated into the geotechnical investigation. Depending upon the type of project, the work may include a review of geologic literature and maps, air photo interpretation, seismic refraction surveys, fault investigation, excavation of exploratory trenches, borings and down -hole logging, and various types of software analysis. Typical projects include geologic hazard studies, landslide evaluations, ocean bluff retreat studies, wave run-up analyses, and geophysical explorations. Geologic hazards reports comply with Section 1803.6 of the CBC, California Geological Survey Note 48, and Special Publications 42 and 117, as applicable. INFILTRATION/PERCOLATION TESTING Infiltration and/or percolation testing may be performed for projects where low -impact developments such as on-site stormwater retention or infiltration is planned, or where on-site wastewater disposal may be necessary. Services may include excavation of witness pits or borings to identify the soil profile; drilling, presaturation and testing of percolation test holes, double -ring infiltration testing, along with interpretation of test data and preparation of a written report. Typically, testing includes an initial background evaluation based upon review of existing data and the proposed development plan, excavation of multiple test pit test locations, and infiltration/permeability or percolation testing (for on-site wastewater disposal). The specific methods used will depend upon the purpose of the testing, the specific site conditions and type of development planned. Test results form the basis of determination of whether the site conditions are suitable for infiltration or percolation, and establishes rates to be used in design calculations. EARTH SYSTEMS I SOQTO PROVIDE ON-CALL MATERIALS TESTING SERVICES I MAY 23, 2023 1 CITY OF LA QUINTA GEOTECHNICAL CONSULTATION For some on-call contracts, geotechnical engineering/geologic investigation may not be necessary, but there may be concerns of a geotechnical nature for which the City would like expert advice, such as a high groundwater condition or unstable soils. Earth Systems has a full staff of experienced geotechnical engineers and geologists available to provide such consultation on an as -needed basis. We can also provide consultation regarding issues such as pavement deterioration, unstable slopes, or forensic studies for buildings or other structures. Plans and specifications can also be reviewed for Standard of Care, adherence to City Standards, or for conformance to applicable reports. FORENSIC STUDIES Occasionally, issues with an existing structure occur in the form of cracks, settlement, or other forms of distress. Causes can range from deficiencies in construction materials, improper construction techniques, settlement of artificial fill soils, or other factors. Identification of the cause of distress is key to developing an appropriate mitigation strategy. Earth Systems has a wide array of forensic services and tools available to assist in forensic evaluation, include floor level surveys, unreinforced masonry testing, concrete evaluation, structure load testing, tendon/reinforcing steel location, pulse velocity testing, and sounding/ echo impact testing. CONSTRUCTION OBSERVATION, SPECIAL INSPECTION AND MATERIALS TESTING SERVICES During construction of projects, Earth Systems can provide geotechnical consultation and sampling, testing and/or special inspection of construction materials including soil, concrete, asphalt concrete, masonry, steel, bolting, and spray -applied fireproofing. This may involve site visits by a qualified engineer or geologist, sampling, testing and/or special inspection of materials by a qualified field technician or special inspector, and laboratory testing of soil materials as necessary to support the project. As part of these tasks, resolution of issues associated with the geotechnical properties of the site and construction materials may be necessary; we are available to attend meetings and consult with the City to discuss any such issues. Scheduling of services is conducted through our dispatcher, who is available (in person, not a message machine) from 7:00 a.m. to 5:00 p.m. Monday through Friday. Sampling and testing will typically be conducted at the direction of the City. Daily reports detailing the progress of the work and the services provided will be left at the site. The results of the tests/inspections will be provided in periodic summary reports, not to exceed 14 days from the date of the last test/inspection when needed. Materials test reports will be provided upon completion of the tests. Results of materials tests are generally available within 48 hours of the material's submittal. All test reports will be prepared or reviewed by Earth Systems' project manager Kevin Paul, or qualified reviewer. Test reports will be sent to the City; the reports will include all of the test results, regardless of the satisfactory or unsatisfactory outcome of the tests. The reports will indicate the location of samples, any special sampling procedures used (as applicable) and will clearly indicate what materials were sampled and what test methods were used. Concrete tests will show the specified design strength. The test reports will contain a definitive statement as to whether or not the materials tested comply with the EARTH SYSTEMS I SOQTO PROVIDE ON-CALL MATERIALS TESTING SERVICES I MAY 23, 2023 1 CITY OF LA QUINTA 8 project plans and specifications, and other requirements as appropriate. Any deviations will be promptly reported. Test results not meeting the project requirements will be logged separately and the retests or remedial measures taken will be reported. All reports are reviewed by the project manager, and peer- reviewed by another professional staff member to assure report accuracy and quality. We are committed to deliver our work products in a timely manner and are always available and responsive to phone or email communications as well as requests for meetings or on-site consultation. QUALITY ASSURANCE/QUALITY CONTROL All geotechnical and materials testing services will be performed in accordance with the California Building Code (CBC) requirements and standards for public improvement projects, project plans and specifications, and the City's Quality Assurance Program (QAP) as applicable. Geotechnical engineering reports comply with the requirements of Sections 1803.1 through 1803.6, and J104.3 and J104.4 of the applicable edition of California Building Code (CBC) and California Geological Survey (CGS) Special Publication 117, as applicable; geologic hazards reports comply with Section 1803.7 and J104.4 of the CBC, CGS Note 48, and CGS Special Publications 42 and 117, as applicable. Geotechnical engineering investigations are supervised by Registered Geotechnical Engineers who develop programs for subsurface exploration, laboratory analysis, and data evaluation. Projects involving a geologic scope are supervised by a Certified Engineering Geologist. All reports are peer-reviewed by another staff professional experienced with similar projects and certified or licensed in the appropriate discipline. For materials testing and special inspection projects, all work is overseen by the project manager, who visits the sites and reviews the inspection/testing program with field and laboratory personnel. All reports are reviewed by the project manager, and peer-reviewed by another professional staff member to assure report accuracy and quality. MONITORING OF BUDGETS AND SCOPES Earth Systems recognizes the need for budget control on publicly funded projects and works collaboratively with our public agency clients to control costs associated with geotechnical and materials testing/ inspection services, and we understand the need to adhere to the project's allocated budget. Geotechnical and geologic investigations are typically provided on a fixed fee basis, while materials testing, special inspection and core sampling services are provided on a time -and -materials basis. Prior to the start of the work, budget estimates are developed based upon reviews of project plans and contractor schedules for various aspects of the sampling and testing program. Placement of materials, the schedule of the contractor and the progress of the work are critical factors that can affect fees. Other variables include the location of material fabrication, identification of construction materials, and the need for retests. To avoid unanticipated budget overruns, we implement a budget tracking system. Hours for observation or sampling/testing are estimated based upon the contractor's construction schedule, and are tracked by category, i.e. soil, concrete, asphalt concrete, etc. If the progress of the work begins to deviate significantly from that shown in the project schedule for any category, thus potentially affecting fees, the client is notified. Similarly, if other situations such as unidentified materials, nonconforming materials, or excessive retesting occur, he or she is informed and apprised as to the effect upon the project budget. This affords the City the opportunity to convene with the contractor to discuss the project schedule or other factors that may affect testing or observation fees, and measures that can be taken to better control the progress of the work. COMMUNICATION WITH CLIENTS AND STAKEHOLDERS Excellent client service is the hallmark of Earth Systems' reputation and has earned us extensive commendations and loyalty from clients and stakeholders. We respond rapidly to client requests and our goal is to always work collaboratively with clients, the design team, and contractors while meeting tight schedules and deadlines. We accomplish this by clear communication, always keeping our clients and other stakeholders apprised of project milestones and being respectful of the project schedule and budget. Should issues arise on a project, we immediately notify the client and work with all involved parties to come to a resolution that is practical, constructible, cost-effective, and minimizes project delays. We are committed to deliver our work products in a timely manner and are always available and responsive to phone or email communications as well as requests for meetings or consultation. EARTH SYSTEMS I SOQTO PROVIDE ON-CALL MATERIALS TESTING SERVICES I MAY 23, 2023 1 CITY OF LA QUINTA The schedule for services will vary depending upon the type of service requested under the on-call contract. Requests for consultation are responded to immediately, with site visits typically scheduled for the same or the following week. For geotechnical engineering or engineering geology investigations, the time -frame will generally be four to six weeks following the Notice -to -Proceed, and may be influenced by such factors as weather and site accessibility. Materials testing and special inspection timeframes are governed by the contractor's construction schedule; a minimum of 24 -hours' notice is requested for inspection services, however, we endeavor to have testing and inspection personnel available as necessary to serve the needs and timeframes of projects.
