STATEMENT OF QUALIFICATIONS UNDERSTANDING OF THE SCOPE OF SERVICES It is our understanding that the City of Santa Ana is seeking qualified firms to provide avariety ofgeotechnical engineering related services on an as -needed or "on - call" basis for various Public Works projects and or related to City facilities planned throughout the City. LVITM r&q:jW_1k GEOTECHNICAL ENGINEERING Geotechnical investigation and engineering projects will begin the minute we receive a request from the City. Our first step will be to review the plans, specifications, or other information provided to us. If clarification or strategy is needed, we will engage in discussions or meetings with the City so that we can clearly define our scope of work. This is a great opportunity for us to get a thorough understanding of the project and expectations and to lay out an approach that will deliver a completed product that meets or exceeds the City's needs. Once we have a clear understanding of what is expected of us and how we will approach the project, we will begin preparing an individual task order proposal for the project. The task orders are subcontracts for specific items of work that will be related directly back to our master agreement contract with the City. Our task orders will include a clearly defined description of our scope of work, deliverables, and cost estimates. The scope of work description will include any office or research work performed prior to the project such as reviewing maps or prior reports. It will also include, where applicable, written descriptions of our proposed field work, laboratory testing program, and report preparation. Cost estimates will be prepared using the fees and rates laid out in our master agreement contract. REVIEW, RESEARCH & RECONNAISSANCE Work will commence after a task order has been accepted and RMA Group has been given a notice to proceed. Our first steps in the beginning of the project will typically be office research and site reconnaissance. In the office, our professional staff will review any geologic or geotechnical maps relevant to the project area and will review previous geotechnical investigation or design reports that pertain to the project site. A site reconnaissance will be conducted to determine optimal locations where we will take samples, dig trenches, drill borings, or conduct any other work. During site ;r"" RMA Group Every P, oje<t Matters I www.rmacompanles. com reconnaissance, we can mark locations using stakes or spray paint so that they can be easily identified. UTILITY LOCATION & COORDINATION The next steps in a geotechnical project involve utility location and coordination with the City and other involved parties. In accordance with the law, we will notify Underground Service Alert (USA) once we have marked our field exploration locations and inform them that we plan to dig. They will then take the next two business days to notify all companies or agencies with utilities in the area to mark those utilities on the project site. This will need to be coordinated with the City and anyone who might own or manage the site so that the utility locators have access. Some project sites may have utilities or underground tanks that USA will not know about. Depending on the type of property, RMA Group may decide to employ a private utility locator to use ground penetrating radar and other tools to locate utilities. This extra measure can act as a safeguard against drilling through existing utilities, which can result in tens of thousands of dollars in damages. After the utilities have been marked and it is confirmed that there are no utilities at the locations where we plan to excavate or bore, RMA Group will coordinate with all involved parties to schedule a date to perform the field exploration. We will then contact local drilling, excavating, or coring companies and schedule them for the work. Depending on the requirements of the project, we may need to schedule additional staff members or technicians to be on site during the exploration as well. FIELD EXPLORATION When everyone involved in the fieldwork meets on the project site, we hold a brief safety meeting to go over potential hazards and to make sure everyone has the appropriate personal protective equipment. Our investigations will typically consist of drilling or excavating as deep as necessary and taking appropriate soil samples and pavement core samples. When excavating or trenching, we will only be able to take disturbed or bulk soil samples. If drilling using a hollow -stem continuous flight auger, we can take bulk samples, SPT samples, and undisturbed ring samples. The types and quantities of samples we obtain will be dependent on the number of different soils encountered and on our proposed laboratory testing program. After field exploration is complete, the openings are typically CITY OF SANTA ANA I PUBLIC WORKS GEOTECHNICAL ENGINEERING SERVICES Page 19 JULY 12, 2018 118-1052-P
