1. Assist the City in obtaining all permits required to comply with applicable Federal, State, and Local environmental laws and regulations. 2. Preparing and/or reviewing construction plans, specifications and project design reports including slope stability analysis, sub-surface and surface drainage reports, grading plans and structural design in accordance with current standards developed by the American Association of State Highway and Transpiration Officials (AASHTO) and California Department of Transportation (Caltrans). 3. Perform soil borings in locations as directed by the City. Each soil boring shall include pavement cores to determine existing pavement thickness. This shall also include coring through any concrete pavement or base that may be encountered. Soil borings will extend to the depth indicated, as measured from the top of the existing pavement. 4. Measure and record the boring logs of all pavement and aggregate base thickness. The composition and description of the aggregate base shall also be reported on the boring logs. Sufficient samples of aggregate base and sand subbase materials shall be obtained in order to perform sieve analysis testing if requested by the City. 5. Measure and record the distance of the actual boring location from the nearest curb line and from another roadway feature. Sampling locations will be marked in the field by a representative of the City. Boring locations shall not be offset for reasons other than avoiding conflicts with existing utilities, parked cars, trees, or other unmovable obstacles. 6. Perform any laboratory testing required to provide comprehensive soil boring logs and/or geotechnical reports. This shall include, at a minimum, visual engineering classification of all samples (in accordance with the Unified Soil Classification System, USCS) as well as moisture content and soil strength tests on cohesive samples. All core thickness shall be measured in the laboratory to verify measurements obtained in the field. Laboratory testing shall be included in the cost of the soil borings. 7. Perform a laboratory material acceptance standard test, which includes a gradation test, compaction curve, R-Value, sand equivalent test, and durability index test.
