Item No.: 8g_Supp Meeting Date: December 9, 2025 Pier 91/ Pier 66 Cruise Shore Power Extension Project Design Authorization for Progressive Design Build Contract Action Requested Request Commission authorization for the Executive Director to approve funding to execute a PostValidation Amendment to the alternative public works Progressive Design Build contract, MC-0322060, for the T91/P66 Cruise Shore Power Extension (C801983) project to further advance design and complete the development and negotiation of a Guaranteed Maximum Price. Total requested for this action is $5,000,000 for a total project authorization of $15,450,000. 2 Project Purpose • In July 2024, Commission Order No. 2024-08 was passed mandating that all homeport cruise ships connect to shore power by 2027. • To meet the mandate, the existing shore power systems need to be extended at Pier 91 and Pier 66. - Currently, the shore power cables cannot reach from the berth connection point to plug-in locations on all shore power capable ships. • This project will provide maximum flexibility in how ships with different shore power configurations berth at the pier so they can connect to shore power. 3 Details • Skanska USA Building Inc. (Skanska) has completed the Validation Period for both Pier 66 and Pier 91 shore power extension projects. • A robust berthing study and mooring analysis was conducted at both piers to determine the optimal shore power connection locations and quantity • Alternative shore power pathway routing options were analyzed 4 Example Terminal 91 Berthing Analysis 5 Example Terminal 91 Mooring Analysis 6 Shore Power Routing Options Considered Pier 66 • Adding a new conduit to existing conduit hangers • Routing the conduit along the east face of the pier • Penetrating the wave barrier wall to route the conduit from the south to north end of the pier • Routing the conduit along the west side of the pier and utilizing the existing openings on the west side of the wave wall to pass through Pier 91 • Through the ballast on the wharf • Through the bulkhead wall and then below the wharf, utilizing conduit hangers anchored to the underside of the pier • Through or over the existing cruise building • Underneath the existing cruise building via horizontal directional drilling (HDD) • Through the upland area between the existing bulkhead cap and cruise building, which ranges from approximately 5 to 10 feet in width 7 Pier 91 Proposed Shore Power Routing 8 Pier 91 Recommendation • Advance Design and GMP development for the full scope of the shore power extension project at both P91. - The conduit route through the ballast on the wharf was identified as the optimal solution. • This approach was selected based on: - Cost efficiency, - Straightforward construction process - Absence of in-water permitting requirements - Minimal risk of encountering unforeseen subsurface features - (2) new sawtooth boxes are recommended on the west berth at footmark 450' and 790' - (2) new shore power connection points are recommended on east berths at footmark 450' and 849' - Replacement of the existing sawtooth boxes on the east and west berths are recommended to modernize the equipment and allow for maximum flexibility in the use of the mobile cable positioning devices (CPD). - (2) new 100-ton bollards near the 1,200' footmark of the west berth 9 Pier 66 Recommendation • Advance Design and GMP development for the shore power extension project at P66. - The current system is sufficient for all current and scheduled vessels through 2027. An additional sawtooth box would allow for ships that may call in the future. - (1) new shore power connection point is recommended at either footmark 793' or 372' - More analysis is necessary at P66 due to potential issues with fixed gangway Bertha and a determination will be made during Design phase if it should be advanced to construction. - When design has progressed to between 60% and 90%, a decision will be made to either advance or remove the P66 scope from the project based on the cost benefit of adding a new connection point at this time. 10 Cost Breakdown and Target GMP Cost Element Planning through Validation Pier 91 Pier 66 Design Pier 91 Pier 66 Material Pre-Procurements (Watts) Pier 91 Pier 66 Construction Pier 91 Pier 66 Target Guaranteed Maximum Price (GMP) Design and GMP Develop.

In July 2024, Commission Order No. 2024-008 was passed requiring all homeport cruise ships to connect to shore power by 2027. To meet the mandate of this order, scope for this project was expanded to include multiple additional connection points on both the east and west berths of Pier 91, as well as adding a third connection point to the existing shore power system at Pier 66. 18 Cone of Certainty We are here 19 RISKS DESCRIPTION PROBABILITY IMPACT MITIGATION Constrained Schedule Delivery required by 2027. Minimal work windows due to cruise season, commercial fishing season, tribal agreements, and fish window if in-water work is needed have high potential to delay in-service date past cruise season start in 2027. High High Utilize Progressive Design Build project delivery to accelerate timeline. Pre-purchase of long-lead items. Seattle City Light Terminal 91 Operations Agreement Existing operations agreement between cruise lines and SCL does not account for increased connections during peak power usage times during the week. Negotiation of new agreement when Port takes ownership of the shore power equipment may result in higher usage costs, and interruptions in power delivery during the week. Med High Early engagement with SCL to do system impact study and begin negotiation of agreement terms for power delivery. Supply chain uncertainty Supply chain logistics could delay project delivery. Tariffs could impact ability to procure long-lead electrical equipment by 2027 and create uncertainty in pricing. Med High Adding cost contingencies to account for tariff price impacts. Early execution of Watts contract to begin procurement of long-lead shore power equipment in advance. Ownership of the existing cruise shore power system at T91 Ownership is still held by Carnival Cruise. Logistics of ownership transfer could drive up project costs. Med Low Coordination with other projects at Terminal 91 Permitting Project Risks There are many other projects scheduled on Pier 91 with similar timelines to the cruise shore power project: gangways, water line replacement, dock rehabilitation, west berth dredging. Permitting assumptions are aggressive and assume no inwater work. This could change depending on how the contractor must construct the project. In-water work, or any other permitting delays will delay the project. Cruise Operations is in negotiation to transfer ownership to the Port. High Med Identification of all on-going and upcoming construction work at Terminal 91. Requirement of logistics plan by PDB to account for constraints of other projects. High High Progressive Design Build project delivery will allow for early collaboration on design and permitting to the extent feasible. 20
