KimlepMorn Warner Avenue Street Improvements 1/10/2018 Liquefaction Evaluation and Foundation Design: Our team will conduct a geotechnical field review as follows: • One hollow stem auger boring to the depth of approximately 50 feet bgs and two CPT to a maximum depth of 50 feet bgs or refusal • Obtain bulk, Standard Penetration Test (SPT) and Modified California soil samples at selected depths We will compile data and geotechnical analysis of the field and laboratory tests consisting of analyses to evaluate and provide recommendations pertaining to the following: • Grain size distribution and Atterberg Limits/Plasticity Index • Moisture content and dry density • Direct shear and Unconfined compression tests • Consolidation and Swell/Collapse Potential • Liquefaction and settlement analysis based SPT and CPT data • Foundation design criteria for new soundwalls (this is to confirm Caltrans standard plans can be used for the sound wall design) We will prepare a report presenting the results of field exploration, geotechnical laboratory testing, engineering analyses including liquefaction analysis and foundation design, as well as conclusions and recommendations relative to the project. Deliverables: Draft Soil Report, Final Soil Report, 60%, 95%, and 100% Plans, electronic files in Microstation V81 and PDF (final plans will be sealed and signed), and responses to previous review comments from the City Task 21: Construction Support Kimley-Horn will assist the City during the construction phase by responding to the Contractor's RFIs regarding design, and providing clarifications. Changes in the overall design concept are not part of this scope. A 12-month construction duration is assumed. We have included up to 5 RFIs and attending one preconstruction meeting. We will prepare record drawings by updating the approved design drawings based on one set of redline markups provided by the Contractor or City staff. Independent verification is not included in this scope. Significant deviations from the original design documents are not accounted for in this scope. The purpose of the record drawings is to create a deliverable that will represent the built condition for the City's records, as recorded by the Contractor. This scope of work is based on hours provided on our fee schedule. Additional construction support can be provided as needed on hourly rate basis. Deliverables: Record Drawings: One hardcopy and one electronic (PDF format and Microstation V8l) Optional Items Task 1: Community Outreach Kimley-Horn will prepare and attend a total of two community outreach meetings and workshops, one at the 60% and one at 95% design levels to demonstrate and discuss project features. This encompasses a board presentation showing the 60% and 90% level design plans and other related information. 8 1 P a g e
