a. Collect near surface representative bulk, soil samples of the proposed roadway subgrade <br />(total of four samples). Samples will be tested for subgrade modulus for purpose of <br />pavement design. <br />F. Review soil samples collected from drilling. <br />g. Complete geotechnical laboratory testing of representative soil samples to support <br />assignment of engineering properties. Laboratory testing methods and quantity of tests <br />will be reactive to the conditions encountered in the borings. Laboratory testing is <br />assumed to include moisture content determination (ASTM D2166, 10 tests), grain size <br />analysis (ASTM D422, 10 tests), percent fines determination (ASTM D1140, 10 tests), <br />and Atterberg limits (ASTM D4318, 4 tests). It is assumed that corrosion testing of water <br />or soil samples is not required. This scope does not include any testing or screening for <br />environmental contaminants. Any physical evidence of environmental contamination <br />observed during the investigation will immediately be reported to COUNTY. <br />h. Participate in one teleconference discussion with the County regarding preliminary <br />results of the field investigation. <br />The soil boring locations will be surveyed to the project layout site plan. <br />Adhere to appropriate maintenance of traffic plan and control (provided by COUNTY) <br />While drill rig is at the project site. <br />Deliverables: Geotechnical Report summarizing the results of the desktop and field <br />investigation and providing pavement recommendations. Jacobs will submit one <br />electronic draft report for review by COUNTY, then will incorporate one round of <br />comments and submit electronic final report sealed by a registered Professional <br />Engineer. <br />Assumptions <br />The geotechnical scope and cost estimate assume that subsurface conditions are typical of the <br />area and can be adequately characterized with the field investigation program described herein. <br />Geotechnical Engineering and Analysis Report <br />• Review publicly available geologic maps, nearby well logs, and other available <br />geologic/geotechnical information at or near the project site. <br />• Analyze collected field investigation data to develop a geotechnical engineering design <br />profile and relevant geotechnical properties for materials in the profile. <br />• Evaluate and provide design and construction recommendations roadways and utility <br />construction. <br />• Provide grain size analysis results of bank and channel material for use in scour analysis. <br />• Participate in up to two, one-hour design team meetings by phone to discuss <br />geotechnical design and construction elements of the project. <br />• Provide up to 4 hours of Plans and Specifications support throughout the project. <br />If additional geotechnical investigation and laboratory testing is required, an amendment <br />request well be submitted to COUNTY. <br />• Execution of fieldwork will not be delayed by travel and/or self -isolation restrictions locally and <br />or nationally imposed due to COVID-19. Jacobs is not responsible for schedule changes related <br />to COVID-19. <br />Deliverables <br />• One (1) draft Geotechnical Report, electronic submission in PDF format. <br />• One (1) final Geotechnical Report. To be delivered after receipt of COUNTY comments. <br />Electronic submission will be in PDF format. <br />
