Amendment 1 PSA with Brown and Caldwell for Port Gardner Storage Facility Project Exhibit A Scope of Work 21 • Fulfill data requests to complete Project permit applications. • Also see Phase 450. Meetings • Permitting kick-off meeting (BC and ESA). • Regularly scheduled progress check-in meetings. • Workshop attendance and City check in meetings: − Intermediate Design Review Workshop − Final Design Review Workshop Work Products • Project permitting matrix for both demolition and site construction activities. • Project permit applications review comments for those permit applications prepared by the City. • Critical areas Technical Memorandum (TM). • Draft and final cultural Resources Report (combined with West Marine View Drive Project). • Draft and Final Inadvertent Discovery Plan (combined with West Marine View Drive Project). • Tribal correspondence to be combined with West Marine View Drive Project. • Field cultural resources monitoring reports. Task 416 – Third-party Geotech Review (Earth Mechanics) Objective: Provide a third-party review of PGSF Project Geotechnical Data Report and Geotechnical Engineering Reports. This third-party review is performed as a risk identification and mitigation step for the proposed site improvements. Findings from the review will be incorporated into the final Geotechnical Engineering Report. Activities/Approach: This task includes the following activities: • Review project design materials including the PGSF Basis of Design Report, preliminary design documents, and Kimberly-Clark 1980 record drawings to understand proposed facility upgrades. • Review documentation of previously completed site geotechnical investigations. This work includes 1952 site test boring record, 1995 Dames & Moore Geotechnical Investigation, and the 2014 Shannon & Wilson, Inc. Geotechnical Evaluation of Kimberly-Clark Site. • Review the June 2023 draft PGSF Geotechnical Data Report developed by HWA GeoSciences Inc. • Review the Intermediate design draft and final design PGSF Geotechnical Engineering Reports developed by HWA GeoSciences Inc. • Confirm geotechnical engineering assumptions and identify project risks associated with facility design and proposed geotechnical improvements. • Provide risk mitigation recommendations if warranted. • Review geotechnical related specifications including but not limited to Sections 01 11 10 Geotechnical Information, 31 23 00 Excavation and Fill, 31 23 19 Dewatering, 31 41 00 Shoring, and 33 05 30 Settlement Monitoring. Task Assumptions • The third-party geotechnical review will be performed by BC subconsultant Earth Mechanics Incorporated (EMI).
