Item No.: 10a_Supp
Meeting Date: September 9, 2026

Terminal 91/Pier 66 Cruise Shore Power Extension
GMP Contract Amendment and
Pier 91 Rehabilitation Validation Funding

Shore Power 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.

Structural Scope Addition - Pier 91 West
• Latest inspections have shown that the
condition of the pier structure in the project
footprint (DU#9202) is deteriorating at an
accelerated rate.
• Operational restrictions implemented on twelve
(12) precast concrete deck panels.
• Pier structure must be rehabilitated ahead of
the west berth shore power to avoid impact to
Cruise, resulting in 1-year delay. P66 and P91
east berth will remain on schedule.

• The cost of the project now includes the cost of
the added scope previously budgeted under a
separate CIP. Overall, combining the projects will
result in an estimated net savings of $20M to
the capital plan from efficiencies and innovative
design approach.

Action Requested
Request Commission authorization for the Executive Director to approve funding to:
1. Execute a Guaranteed Maximum Price (GMP) Contract Amendment to the alternative public works Progressive
Design Build contract, MC-0322060, for the T91/P66 Cruise Shore Power Extension project to complete
construction of the Pier 66 and Pier 91 East shore power extension systems, bollards, and limited deck panels
replacement.
2. Authorize funding for a Validation Phase to include the rehabilitation of the section of Pier 91 deck delineated as
Development Unit (DU) #9202.

Total amount requested for this action is $49,330,000 for a total project authorization of $69,980,000,
and an estimated total project cost of $116,480,000.

Details of Request
• The contract will now proceed with two (2) separate milestone scopes for which separate GMPs will be
negotiated:
- Milestone 1 (2027) - today's funding request
A. Completion of Pier 66 shore power extension
B. Completion of Pier 91 east berth shore power extension
C. Limited deck panel replacements
- Milestone 2 (2028) - validation phase in today's request
D. Completion of the Pier 91 west berth shore power extension
E. Full rehabilitation of Pier 91 west dock
*Construction funding in future request
•

Final GMP for Milestone 1 has been successfully negotiated and amendment execution will follow today's request.

*Overall funding for DU#9202 has been accounted for through cash flow reduction in CIP #801294 T91 Dock Rehabilitation project. Funding for Validation
scope will be accounted for in reduction of scope for T91 Programmatic Design contract P-00322462 SD1 - T91 Dock Rehab 30% Design. Overall Capital
Plan reduction of $20M is anticipated by combining west berth shore power and DU #9202 under the Progressive-Design-Build contract.

RISKS

DESCRIPTION

Constrained Schedule

Project schedule is highly constrained by regulated work
windows

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.

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.

Coordination with other
projects at Terminal 91

Tribal Concurrence

PROBABILITY

MITIGATION

Utilize Progressive Design Build project delivery to
accelerate timeline. Pre-purchase of long-lead items.

Early engagement with SCL to do system impact study
and begin negotiation of agreement terms for power
delivery.

Early execution of Watts contract to begin

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.
Constrained schedule requires some work during tribal
fishing season. Concurrence needed at T91.
