AGENDA MEMORANDUM                Item No.       4c 
ACTION ITEM                   Date of Meeting   November 28, 2017 
DATE:    November 16, 2017 
TO:     Dave Soike, Interim Executive Director 
FROM:   Wayne Grotheer, Director, Aviation Project Management Group 
Wendy Reiter, Director, Aviation Security, Airfield 
SUBJECT:  Employee Security Screening Phase 1 (CIP #C800880) 
Amount of this request:          $1,550,000 
Total estimated project cost:       $2,950,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) advertise and execute
major public works contracts to construct a new airline baggage service office and enlarge the
north employee screening room at Seattle-Tacoma International Airport; (2) procure additional
security equipment, and, (3) use Port crews to install infrastructure for the new equipment.
This authorization is for $1,550,000 of a total estimated project cost of $2,950,000. 
EXECUTIVE SUMMARY 
This request will build a larger employee screening room in the north main terminal than
previously proposed, in order to handle the volume of employees entering the airport security
area at that location. To create space for this screening room construction, the project will
relocate the existing Alaska Airlines Baggage Service Office (BSO) from its current location to a
new location as part of this project. This request will also procure and install additional security
equipment tested as part of the previous authorization. 
This request represents the third authorization for this project. In September 2016 Commission
authorized the build out of one employee screening room and procurement of security
equipment for two employee screening rooms. In March 2017 Commission authorized
completion of both employee screening rooms, safety improvements, and the design,
equipment procurement and construction of a third employee screening room. 
This request focuses on the main terminal building. A future request as part of a separate
project will provide security improvements to facilitate employee screening at airfield access
points.

JUSTIFICATION 
As this project investigated the use of a portion of the Alaska Airlines BSO for a new north
employee screening room it became apparent that the location could not support the queuing
needs of both the BSO and the screening room. This could impact passenger movement around
Baggage Claim Carousel 14. 
The alternative agreed upon by Alaska Airlines and the Port relocates the Alaska BSO to the east
side of baggage claim against the window wall to improve customer service to their passengers 
at both the BSO and the carousel. This will require adjusting the location of passenger
amenities including an electrical charging station and some vending machines. Completing this
move will also allow for an increase in the size of the north screening room to allow it to
function more efficiently with the number of employees using it, primarily Alaska, Horizon and
American Airline employees. 
As an added security measure this project will procure additional security equipment at the
existing employee portals at both ends of the airport. Port Crews will installthe infrastructure 
for the new equipment. 
DETAILS 
Scope of Work 
This project will relocate the Alaska BSO and procure new technology security equipment for
use at the existing employee portals. 
(1)   Construct a new Alaska Baggage Service Office 
(2)   Relocate amenities including an electrical charging station and vending machines 
(3)   Expand the North Employee Screening Room 
(4)   Procure and install new technology security equipment 
Elements within the scope of work could provide a number of opportunities for small and
diverse firms. In partnership with the small business group within the Economic Development
Division, the Aviation Project Management Group is leveraging the Port of Seattle's Small
Business Generator (PortGen) to help outreach, and to maximize small business awarenessof 
this project.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Proceed as planned to use a portion of the Alaska BSO for the north screening
room. 
Cost Implications: $813,000 (Previously authorized) 
Pros: 
(1)   No need to relocate Alaska's BSO 
(2)   No additional funds needed to build out the screening room 
Cons: 
(1)   Passenger flow on both ends of the baggage carousel will be impacted by having two
different queuing functions at that location, one for Alaska passengers and the other
for Employee Screening 
(2)   Alaska Airlines will need more space at a different location not yet identified 
(3)   To accommodate efficient screening for the amount of employees on the north end 
the east wall of the existing BSO will need to be expanded out into the Baggage Claim
area which will further impact passenger flow 
This is not the recommended alternative. 
Alternative 2  Construct the North Screening Room on the north end of the airport. 
Cost Implications: $510,000 
Pros: 
(1)   No need to relocate the Alaska BSO 
(2)   Construction may be completed sooner 
Cons: 
(1)   The screening room may need to be relocated with any future expansion on the north
end of the main terminal. 
(2)   This could restrict access on both sides of carousels 15 and 16 
(3)   This could eliminate the oversize bag window used by the airlines to pass oversize
bags into the bag claim area. 
(4)   This could create a need to relocate the American Airlines BSO 
(5)   This could cause an unsafe condition for employees entering the bagwell where tugs
are loading and unloading 
This is not the recommended alternative.

Alternative 3  Relocate the Alaska BSO, increase the size of the north screening room and
secure the existing employee portals with new technology metal detection. 
Cost Implications: $1,550,000 
Pros: 
(1)   This will eliminate the potential for passenger flow congestion on the west side of
Baggage Claim Carousel 14 
(2)   This will eliminate the need to find more storage space for Alaska 
(3)   This will add another layer of security at the existing employee portals 
(4)   This will provide a more efficient north location for employees to enter the secure
area 
Cons: 
(1)   This will require additional funds 
(2)   This will require additional build out in the bag claim area 
This is the recommended alternative.
