Transaction Agreement (OTA) Time Extension and Change Order 
Amount of this request:                                           $0 
Total estimated project cost:                            $955,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to: 1) execute an OTA with TSA for
a 24-month time extension for the period of performance on the Baggage Optimization Program,
2) execute future Change Orders on the Baggage Optimization Project Phase 2 and Phase 3 
construction contracts (C800612) up to the executed Commission authorization amount that
exceed $300,000 and/or exceed 60 calendar days’ time extensions, and 3) include a Project Labor
Agreement (PLA) for Phase 3. 
EXECUTIVE SUMMARY
The Port of Seattle and TSA entered an OTA in 2013 to reconfigure the baggage system to meet
both the TSA’s and Airport’s needs. The TSA benefits by making its portion of the baggage system
more efficient, reducing maintenance costs, and improving working conditions (safety and
comfort) for federal employees. In the long-term, the Airport benefits by creating a vision of how
the overall baggage system could flexibly grow to meet the long-range capacity of the Airport.
The Baggage Optimization Program is being delivered in three phases. Phase 1 has completed
construction, Phase 2 is under construction, and Phase 3 pre-design has started.  The overall
program is anticipated to be complete in 2027. Phase 2 is approximately 45% complete with an
expected completion date of August 2024. Due to the lack of interconnectivity until the project
is complete, near continuous operation, and a fixed footprint, this project is complex and has
various constructions requiring detailed construction sequencing plans. As part of this request,
Phase 3 would benefit from entering into a project labor agreement.

JUSTIFICATION
OTA Time Extension:
The current OTA commits $94,043,296 toward the program and is currently scheduled to end in
March 2023. This OTA would not increase TSA contributions. However, it would extend the
duration by 24 months to March 30, 2025, when the funds are anticipated to have been spent.
Approximately $3.3M would be returned and de-obligated from the Port of Seattle Baggage
Optimization Program if this OTA is not extended.
Change Orders:
Phase 2 is currently under construction and Phase 3 procurement for a General Contractor and
Construction Management contract (GC/CM) is being developed. Commission action is required
under the General Delegation of Authority if the value of the change order is over $300,000 or 
the additional time is over 60 calendar days. The Baggage Program is requesting authorization 
for the Executive Director to execute any future change orders, so long as the change orders are
within the approved budget. Phase 2 is a $293M project and Phase 3 is expected to be similar in
magnitude. Projects of this size and complexity would typically anticipate several change orders
that exceed $300k or 60 calendar days of time extension. Therefore, it is more expedient to grant
the Executive Director authorization to execute these change orders. 
Project Labor Agreement (PLA):
A project labor agreement will be used for these projects based on the importance of labor
continuity and the need to minimize any risk of impact to operations during construction. 
Diversity in Contracting 
Phase 2 is projected to meet our 2% Women and Minority Owned Business Enterprise (WMBE)
goal. The project team will work with Diversity and Contracting team to conduct outreach and
setting an aspirational WMBE goal for Phase 3. 
DETAILS 
Scope of Work
Phase 2 is currently under construction and scheduled to be complete Q3 2024. This work will
expand the centralized baggage screening area in the airport’s Central Terminal.   This phase will
also replace conveyor systems to the north portion of the bagwell, construct the final baggage
sortation matrix, and add more capacity to the South Satellite baggage system. Concession
storage and the conveyance maintenance shop will be relocated to their final locations.

Phase 3 concludes the Baggage Optimization Program allowing for complete baggage flexibility
to check in any bag into any ticket counter and be delivered to any airplane.  It also
accommodates passenger volume growth and meets TSA safety mandates. This phase will tie-in
all the south end systems to centralized screening, including the International Arrivals Facility
(IAF), and finalize the sortation and ticket counter connections. 
Schedule
Phase 1 was completed in Q2 2020. Phase 2 Is currently under construction and scheduled to be
completed in Q3 2024. Phase 3 design has started in Q3 2022 and is scheduled to be constructed
Q2 2027.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Do not proceed with the request to execute an OTA with TSA for a 24-month time

Amendments and Change Orders on the Baggage Optimization Program up to the executed

Meeting Date: January 24, 2023 
Commission authorization amount for additional design, project and construction management
services that exceed $300,000.00, and/or exceed 60 calendar daytime extensions.
Cost Implications: $3.3M 
Pros:
(1)   None. 
Cons:
(1)   Allocated TSA funds may not be fully utilized and returned to TSA; the Port would have
to fund the money that was returned to TSA to complete the project.
(2)   If the change order execution request by the Executive Director is not granted, the
project will have to repeatedly go back to Commission although the project budget has
already been approved. 
This is not the recommended alternative. 
Alternative 2 – Approve the request to proceed with the execution of the OTA time extension
with TSA, allow the Executive Director to execute change orders within the approved budget, and
allow for PLA to be used on Phase 3. 
Cost Implications: $0 
Pros:
(1)    All allocated funds from TSA will be used on Baggage Optimization. 
(2)   Change order execution within the approved budget by the Executive Director allows
for the project team to move forward without continuously returning to Commission
for approval.
(3)   PLA will help to minimize risk to operations during Phase 3 construction. 
Cons:
(1)   None. 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
Phase 1 was completed at $101,275,000.  Phase 2 has a budget of $415,675,000 with a
substantial completion date of Q3 2024. However, now that we are anticipating about a $20M
savings, barring any major issues, that amount can be rolled into Phase 3. The team has been
projecting a range of $400-$500M for Phase 3, with a likely cost of $432,450,000.
