ACTION ITEM                            Date of Meeting     February 13, 2024 

DATE:     February 2, 2024 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Wendy Reiter, Director Aviation Security 
Eileen Francisco, Director, Aviation Project Management 
SUBJECT:  Automated Screening Lanes Checkpoint Conversion Project (CIP# C801420) 
Amount of this request:              $12,000,000 
Total estimated project cost:         $12,250,000 

ACTION REQUESTED 
Request a single Commission authorization for $12,000,000 for the Executive Director to take all 
steps necessary, including the execution of all contracts, including Public Works, Alternative
Public Work procedures in accordance with RCW 39.10, Goods and Services Personal Services,
Professional Services, other consulting services, and any other types of contracts or agreements
to complete this project. 
EXECUTIVE SUMMARY 
This project will replace Automated Screening Lanes (ASLs) with standard (non-automated)
screening lanes at passenger Security Checkpoints 2 and 3 at Seattle-Tacoma International
Airport (Airport). This work will be completed in Q2 2024 using a combination of design and
construction contracts and port forces. This project is supported by the Transportation Security
Administration (TSA) to mitigate security lines and improve customer service at the Airport. 
JUSTIFICATION 
Passenger loads continue to increase and create long lines at the Airport’s passenger security
checkpoints. There were 50.8 million passengers in 2023, and there is forecasted to be 52.6 
million in 2024. Currently installed ASL’s are not providing the passenger throughput expected,
therefore creating inefficiencies at the passenger Security Checkpoints at which they are
installed, Checkpoints 2, 3 and 5. In addition to underperforming, ASLs regularly go out of service
for maintenance issues, causing frustrations for passengers and the TSA.

Meeting Date: February 13, 2024 
Diversity in Contracting 
For construction, the project team plans to utilize (1) an existing IDIQ design contract, which
has a 25% WMBE goal, and (2) an existing Job Order Contract, which has a 6.3% DBE goal. 
DETAILS 
This project will make modifications to the screening lanes at passenger Security Checkpoints 2 
and 3. The project will convert the Automatic Screening Lanes (ASLs) to standard screening lanes
like those being used at Checkpoints 1, and 4, along with all supporting infrastructure. This
project will provide the Airport with an additional four security checkpoint lanes and improved
queuing space within the terminal. Achieving this project before the busy summer period has
risks, specifically regarding: quality of design, reducing time for investigations, and construction
pushing out beyond intended into the busy period. 
Security Checkpoint 5 will be converted to all standard lanes, as well, inside of the scope for the
SEA Gateway Project. 
Scope of Work 
Demolish existing security screening systems at checkpoints two and three. Deliver and install
new security equipment, provide additional infrastructure as needed, and complete final system
testing and integration of security lanes.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Checkpoints two and three would remain with ASLs in place, rather than removing
and converting them back to traditional lanes. This would keep the number of lanes at eight and
seven respectively and would not increase the number of lanes.

Cost Implications: This would not seek to spend any money on increasing the number of lanes.
There would be no cost implications. 
Pros: 
(1)   No capital cost. 
(2)   Avoids the risk of construction spilling over into summer and causing increased
congestion at checkpoints during a busy season. 
Cons: 
(1)   Does not address the current congestion issues due to lack of suitable lane numbers at
the Port’s checkpoints. 
(2)   Does not support new security directive of providing qualified equipment that meets 
the new Checkpoint Property Screening System (CPSS) requirements. 
This is not the recommended alternative. 
Alternative 2 – Replace 15 ASLs at with 19 traditional screening lanes. In this alternative the work
would be undertaken with a full checkpoint shutdown at a time. Checkpoint two will be
prioritized for K-9 screening, with construction for checkpoint three starting once checkpoint two 
is finished. 
Cost Implications: This would be the less expensive alternative for the construction work. By
shutting down a whole checkpoint, all stages of construction can more efficiently utilize the
space. 
Pros: 
(1)   Faster than alternative two by shutting down a whole checkpoint at a time and allowing
for more efficient construction work. 
(2)   Once checkpoint two is back online, there will be additional lanes to ease some of the
negative congestion effects during checkpoint three’s construction. 
Cons: 
(1)   Will have negative congestion effects during the construction periods. 
This is the recommended alternative.
