SUBJECT:  Secured Area Vehicle Checkpoints (CIP #C801237) 
Amount of this request:                 $550,000 
Total estimated project cost:          $4,300,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to design and prepare construction
documents for the Secured Area Vehicle Checkpoints (SAVCP) project (CIP C801237) at Seattle-
Tacoma International Airport (SEA) for $550,000 out of an estimated total project cost of
$4,300,000. 
EXECUTIVE SUMMARY 
This project will provide the infrastructure required to add security measures to support the
overall security posture at SEA. The North and South vehicle checkpoints include gate arms, a
dedicated inspection area, CCTV cameras, vehicle loop detectors, card readers, and a guard shack
with lighting, windows, and a locking door system. 
JUSTIFICATION 
This project will support SEA compliance with Federal Security requirements for personnel and
vehicles entering the Secured Area under Code of Federal Regulation (CFR) Title 49 Part 1542.207,
Access Control Systems. 
Diversity in Contracting 
The design phase will be conducted utilizing Port staff. The project team in coordination with the
Diversity in Contracting Department will set a Woman and Minority Business Enterprise (WMBE)
aspirational goal for the construction phase. This project will not be utilizing FAA funding.

Meeting Date: February 8, 2022 
DETAILS 
The project involves installing two vehicle checkpoints on the existing north-south vehicle service
road within the SEA airfield. Each location consists of two components: the vehicle gate and an 
inspection area. The vehicle gates will include both card readers and guard shacks to follow
established security procedures for individuals and vehicles entering the Secured Area from other
parts of the airfield. 
During notebook, preliminary design work was conducted which indicated significantly more site
demolition and development improvements would be required to achieve the proposed scope 
and mitigate impacts to Fire and Cargo Operations. These included increased amounts of paving
demolition and restoration, longer concrete encased utility ductbanks and road widening, as well
as cost for relocating a fire hydrant, bollards, and an Airport Operations Area fence. This
additional site development work has increased the estimated cost for this project from
$1,800,000 to $4,300,000. Additional information regarding the source for the additional funding
required to implement the project as proposed are provided below in the Financial Implications
section of this memo. 
Scope of Work 
The project elements described above, and specific scope items below will be aligned and
packaged for construction with the other 2023 Airfield Construction Contracts to capitalize on
concurrent operational impacts and similar airfield work. 
(1)   Construction of two self-contained guard shacks, with lighting, windows, and a locking
door. 
(2)   Construction of vehicle gate arm systems, access control readers, cameras, and vehicle
loop detectors. 
(3)   Trenching,  paving  and  installation  of  cables  for  electrical  and  communication
ductbanks. 
(4)   Relocation of a fire hydrant and bollards and restriping of impervious parking areas to
add a lane to the Vehicle Service Road (VSR) at the Cargo areas. 
(5)   Relocation of a portion of the AOA Fence. 
(6)   Construction of concrete traffic islands for the vehicle gate arms between the lanes.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not install VSR checkpoints on the north and south ends of the Secured Area. 
Cost Implications: $50,000 (Expensed Notebook efforts) 
Pros: 
(1)    No impacts to airfield operations, hardstand parking or tenant leases. 
(2)    Reduced capital spending for 2023. 
Cons: 
(1)   Does not support the overall security posture at SEA. 
This is not the recommended alternative as it does not support CFR Title 49 Part 1542.207. 
Alternative 2  Provide a three-lane checkpoint on the North end and a two-lane checkpoint on
the south end of the Secured Area creating aircraft hardstand impacts. 
Cost Implications: $3,300,000 
Pros: 
(1)    Supports the overall security posture at SEA. 
(2)   Less expensive than Alternative 3. 
(3)    Lowest impacts to VSR traffic during construction. 
(4)    Co-location synergies for security staff at existing facilities. 
(5)    Does not impact airfield operations or leased tenant parking spaces 
Cons: 
(1)    Impacts hardstand operations by eliminating an aircraft parking position. 
This is not the recommended alternative. 
Alternative 3  Provide a three-lane vehicle checkpoint at the North end and a two-lane
checkpoint south end with no aircraft hardstand impacts.
Cost Implications: $4,300,000 
Pros: 
(1)   Supports the overall security posture at SEA. 
(2)   No hardstand aircraft impacts. 
(3)   Adds an additional southbound lane to mitigate backups in the Cargo areas. 
(4)   Adds oversized lane for North and Southbound traffic.

Future Revenues and Expenses (Total cost of ownership) 
As a result of this project, Aviation Maintenance will see a slight increase in O&M cost for
Electrical  and  Electronic  systems,  to maintain  cameras  and  access  controls  and  lighting.
Mechanical systems maintenance will be required for HVAC for the spaces. Labor hours and
materials required will be determined when presented with a clearer scope during the design
phase of the project.
