3500 TERMINAL AVE Geotech Report 2022-10-25

Geotechnical Engineering Design Study 100 Percent Design Phase Port of Everett - South Terminal Wharf & Electrical Upgrades - Phase 2 Everett, Washington This 100 percent geotechnical engineering design report presents our recommendations for design of the Port of Everett South Terminal Wharf&Electrical Upgrades project on Port Gardner Bay in Everett, Washington.The project's significant geotechnical design elements include new crane rail piles and piles for new bents to upgrade the existing 700-ft-long concrete wharf structure.The project also includes associated upland grading, repaving,and utility trenching and installation. We have organized this report into several sections.The first two sections describe the purpose and scope of our work and our understanding of the project.The subsequent sections of the report present our site characterization,assessment of the seismic hazard, and our geotechnical engineering findings and conceptual recommendations. The results of our analyses are presented in tables and figures throughout the report and at the end of the text.The results of field explorations and laboratory tests are provided in Appendices A and B,with historic explorations provided in Appendix C. Further detail regarding our analyses is provided in Appendices D through F.Attachments 1 through 5 are provided,which include information generated by others. PURPOSE, SCOPE, AND USE OF THIS REPORT The purpose of our work is to provide KPFF Consulting Engineers(KPFF), its design consultants,and the Port's selected Contractor,with subsurface information,along with our interpretation and geotechnical engineering recommendations to support the design for the South Terminal Wharf& Electrical Upgrades Project. Our scope of work covered by this report for this project included: • Assessing subsurface conditions using explorations, laboratory tests,and historical geotechnical reports and explorations; • Performing geotechnical and seismic assessment and analysis; • Providing geotechnical recommendations;and • Producing this 100%geotechnical engineering design report. We prepared this report for the exclusive use of KPFF,its design consultants,and the Port's selected Contractor for specific application to the South Terminal Upgrade Project and site location.We completed the work according to generally accepted geotechnical practices in the same or similar localities,related to the nature of the work accomplished,and at the time the services were accomplished.We make no other warranty,expressed or implied. 101111 ILI 19232-01 HARTCROIIUSER December 6,2017
