DATE:     April 3, 2023 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Eileen Francisco, Director, Aviation Project Management 
Wendy Reiter, Director, Aviation Security 
SUBJECT:  Keys for Card Readers Design and Construction Authorization (CIP# C801185) 
Amount of this request:               $2,850,000 
Total requested project cost:          $2,900,000 
ACTION REQUESTED 
Request a single Commission authorization for the Executive Director to (1) complete the design
of the Keys for Card Readers project at Seattle-Tacoma International Airport, and (2) advertise
and award a major works construction contract for its construction. The total project estimated
cost is $2,900,000. 
EXECUTIVE SUMMARY 
Seattle-Tacoma International Airport is divided into two zones, one publicly accessible and one 
secured and accessible only to authorized personnel. This project will improve security at ten (10)
baggage conveyor belt doors at the Airport’s ticketing lobby by treating seven (7) doors with
Airport Access Controls and ten (10) doors with cameras. These improvements will facilitate Port
security management, monitoring, and investigations. This project will also replace one manually
operated door with an automated roll-up door. This new door and the enclosure surrounding the
conveyor pathway will be fire-rated to meet current building code requirements. The anticipated
total project value is $2.9 million. 
JUSTIFICATION 
This project increases airport security by installing access control at the baggage conveyor belt 
doors at the ticketing lobby with direct access from the public to the secured areas of the airport.
This project focuses on the baggage induction points that do not currently have access control
system card readers. This will allow for proper auditing and tracking of access to these areas. This
will also allow for employee access to be added and removed expeditiously. In addition, this
project will provide alarm when the doors are left open, reducing the safety issue if someone
tries to go through the door. The Alarm Response Monitor (ARM) will now have the ability to
receive the alarm and dispatch security when deemed necessary.

Diversity in Contracting 
The project staff intends to utilize an existing Indefinite Delivery Indefinite Quantity (IDIQ)
Contract (P00320886) that has an established 25% WMBE aspirational commitment associated
with the design. In partnership with the Diversity in Contracting department, this project will look
for opportunities to further increase the established commitment under this service directive. In
partnership with Diversity in Contracting, we have established an 8% WMBE aspirational goal 
associated with construction. 
DETAILS 
Initially, the project anticipated replacing four manually operated baggage conveyor belt doors
with automated access control doors along with adding access control to operate another six
doors for a total of ten doors being replaced or upgraded. As project definition progressed it
became clear that three doors would be best completed by other projects that would be
modifying these doors anyway at some point in the near future. Thus, the project will upgrade
seven existing baggage conveyor belt doors that are operated with keys to doors that will be
operated through the Airport’s access control system in the Airport’s ticketing lobby while adding
cameras to view all 10 doors. These upgrades are listed in more detail below. 
Scope of Work 
Includes 
(1) Convert six (6) keyed baggage conveyor belt doors in the ticketing lobby from key locks
to card readers. 
(2) Replace one (1) manual baggage conveyor belt door with a 2-hour fire-rated automated
access control door. 
(3) Improve the fire-rating of the conveyor enclosure behind the replaced door to a 2-hour
fire-rated assembly. 
(4) Install ten (10) security cameras at the baggage conveyor belt doors.

Meeting Date: April 11, 2023 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Replace 4 baggage induction doors, construct code required 2-hour area
separation walls, install 10 card readers, and install 10 security cameras. 
Cost Implications: $5,000,000 
Pros: 
(1)   Provides increased security. 
(2)   Standard across multiple doors to allow for maintainability. 
(3)   Immediate ability to get a notification when a door is left open. 
(4)   Immediate ability to grant or remove access privileges. 
Cons: 
(1)   Requires larger capital expenditure, more than double the current budget. 
(2)   Door retrofit may be impacted due to existing infrastructure that may be in the way. 
This is not the recommended alternative. 
Alternative 2 – Install 6 card readers and 10 cameras. Replace no doors. 
Cost Implications: $2,000,000 
Pros: 
(1)   Requires smaller capital expenditure. 
(2)   Provides increased security. 
(3)   Standard across multiple doors to allow for maintainability. 
(4)   Immediate ability to grant or remove access privileges. 
(5)   Immediate ability to get a notification when a door is left open. 
Cons: 
(1)   Four existing doors not replaced would still be keyed. 
(2)   Will not provide the immediate ability to add or remove access at all doors. 
(3)   Will not prove an immediate ability to get a notification for the door if left open at all
doors. 
This is not the recommended alternative. 
Alternative 3 – Replace 1 baggage conveyor door, install 7 card readers, and install 10 security 
cameras. 
Cost Implications: $2,900,000 
Pros: 
(1)   Provides increased security. 
(2)   Requires medium capital expenditure. 
(3)   Allows other projects to remain fully in control of their own scopes and not rely on this
project to complete one element, i.e., the conveyor door(s). 
(4)   Immediate ability to grant or remove access privileges. 
(5)   Immediate ability to get a notification when a door is left open.

Future Revenues and Expenses (Total cost of ownership) 
Aviation Maintenance anticipates a minimal increase in ongoing operations and maintenance
costs to maintain the additional security equipment and roll-up doors. While the impact from this
individual project is minimal, the overall impact from upcoming security projects will likely
require an additional Electrical and Electronic systems technician to support ongoing operations
and maintenance.
