Item No.: 8h_Supp Date of Meeting: February 13, 2024 Terminal 91 Domestic Waterline Renewal Robert Hoyman, Facilities Project Manager 1 Scope • Remove existing galvanized pipe, fittings, supports and flex- Connections. Approximately 8,000 LF of replacement & upgrades. • Replace all materials with new stainless steel grooved pipe, fittings, supports, bracing and flex-connections/expansion joints. • Code Upgrades: Seismic Bracing, added support, expansion/isolation joints. • Work will be performed with the least impact to operations and other project work. Limitations • Work at Pier 91-South will be performed outside the Cruise Season (October to April) • Work hours under the piers will be contingent on tidal action. • Work to be planned over extended duration based on level of need and coordination with other project work and operational needs. 2 Range of Need • Timeline Perspective 3 Project Risks RISK DESCRIPTION PROBABILITY IMPACT MITIGATION Permitting Compliance with Low Med Perform work using skiffs or floating Federal In-Water Permit platforms rather than attached During Fish Window scaffold.

PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
