SUBJECT:  Checkpoint 1 Relocation Construction Authorization (CIP #C801093) 
Amount of this request:              $26,700,000 
Total estimated project cost:         $37,000,000 
Request Commission authorization for the Executive Director to (1) advertise and award a
major works construction contract for the relocation of Checkpoint 1 at Seattle-Tacoma
International Airport, include a Project Labor Agreement, and (2) use Port crews for support
activities. The amount of this request is $26,700,000 of a total estimated project cost of
This project is needed to improve the level of service for airline passenger security screening at
the Airport. The Airport currently has five checkpoints spread across the Ticketing Level. The
current Checkpoint 1 located at the south end of the Ticketing Level is undersized, has an
inefficient configuration, and will not be able to accommodate newer screening technologies 
proposed by the Transportation Security Administration (TSA). With the current conditions,
Checkpoint 1 is only suitable for pre-check passengers, which limits the airport's overall
screening flexibility and effectiveness. The relocation of Checkpoint 1 would enable other Main
Terminal checkpoint and check-in improvements as part of the Main Terminal Optimization
Plan (MTOP). 
This project will relocate Checkpoint 1 from its current location on the Ticketing Level to the
lower Baggage Claim Level to provide additional screening throughput flexibility and a more
adequate level of service for our passengers. Along with supporting upgrades, the project will
create new queuing, travel document verifications, and additional security screening lanes
which will accommodate future TSA technology.

COMMISSION AGENDA  Action Item No. _10b__                              Page 2 of 5 
Meeting Date: March 22, 2022 
This project was reviewed and approved by the airport airlines though a majority-in-interest
(MII) vote in 2020. 
Inability to accommodate efficient technology and adequate queuing for passenger security
processing at Checkpoint 1 will result in continued deterioration of passenger level of service in
the Main Terminal as demand increases. Passenger security screening  at the Airport is
experiencing stints of systemic failure, resulting in excessive wait times and impacts to other
terminal processes. Without implementation of additional security screening capacity and
efficiency,  it  is  distinctly  possible  that  queues  will  become  unmanageable,  resulting  in
passengers experiencing more and more missed flights.
Relocation of Checkpoint 1 to the lower level would provide additional processing capacity and
operation area to improve passenger level of service. An enhanced Checkpoint 1 would provide
additional compliant screening lanes, TSA support spaces, adequate queuing to meet peak
demand, and flexibility to accommodate current and evolving screening protocols. This lowerlevel
checkpoint will serve all passengers but will primarily benefit passengers using the South
Satellite Concourse and passengers dropped off on the arrivals curb during peak departure
periods, helping to mitigate curb congestion. It also introduces new opportunities for demand
management, which are being considered in other initiatives. Passengers using Checkpoint 1
would have direct access to the South Satellite Transit System platform and ultimately any gate. 
Diversity in Contracting 
There will be a 14% women and minority business enterprise (WMBE) aspirational goal for the
construction contract. 
This project will relocate the existing Checkpoint 1 from its current location on the Ticketing
Level to a new expanded location on the Baggage Claim Level to increase passenger processing
capacity. In addition, the project scope creates a "meeter/greeter" area and circulation in the
area for internationally arriving passengers and integration of new public art displays to
enhance pre-security civic space at SEA. 
Scope of Work 
The scope includes the following elements: 
(1)   New security lanes designed to current TSA standards 
(2)   Demising of security checkpoint from the rest of the Bag Claim level and Gina Marie
Lindsey (GML) Arrivals Hall 
(3)   Removal of Bag Claim 1 device 
(4)   Expansion of glass wall around the GML Hall and the Grand Staircase 
(5)   Structural upgrades to support new glass walls 
(6)   Removal of architectural elements to increase circulation in the GML Hall

Alternative 1  Keep Checkpoint 1 on the Ticketing Level as-is 
Cost Implications: $2.8M 
(1)    No capital investment required. 
(2)   All checkpoints will remain on ticketing. Less confusion for the traveling public. 
(1)   Does not increase checkpoint capacity. 
(2)   Current checkpoint will continue to only screen pre-check travelers. 
This is not the recommended alternative. 
Alternative 2  Relocation Checkpoint 1 to Bag Claim Level 
Cost Implications: $37,000,000 
(1)   Creates ideal amount of space for queuing, document check, screening, and recomposure.

(2)   Provides additional area for passenger screening without expanding the building
(3)   Locating a passenger screening checkpoint on a different level than existing
checkpoints and with additional lanes is likely to provide a moderate benefit to the
TSA staffing formula and may result in additional Transportation Security Officers
allocated to the Airport. 
(4)   Existing Checkpoint 1 location can remain operational during a portion of construction
(5)   Allows other portions of the MTOP program to proceed without having to reduce
capacity (based on the current airport wide passenger screening capacity). 
(1)   Baggage claim level is not a typical location for passenger screening and wayfinding to
this checkpoint will likely be challenging to resolve. 
(2)   Requires additional TSA staff. 
This is the recommended alternative.

Annual Budget Status and Source of Funds 
This CIP C801093 Checkpoint 1 Relocation was included in the 2022-2026 capital budget and
plan of finance with a budget of $40,000,000. A capital budget decrease of $4,900,000 was
transferred to the Aeronautical Reserve CIP (C800753) resulting in zero net change to the
Aviation capital budget. Revised budget includes a transfer of scope from Airline Realignment
for the build-out of the United Baggage Service Office. The TSA screening equipment would be
treated as public expense and budgeted in the operating budget. The funding source will be the
Airport Development Fund (ADF) and revenue bonds.
