ACTION ITEM                   Date of Meeting    December 12, 2017 
DATE:    December 6, 2017 
TO:     Dave Soike, Interim Executive Director 
FROM:   Wayne Grotheer, Director, Aviation Project Management Group 
Michael Ehl, Director, Aviation Operations 
SUBJECT:  Automated Screening Lanes at Seattle-Tacoma International Airport (CIP#C800920) 
Amount of this request:                $0 
Total estimated project cost:      $17,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) proceed with construction
and installation of automated screening lanes at security checkpoints 2, 3 and 5 at Seattle-
Tacoma International Airport; and, (2) use Port crews for construction efforts. The total
estimated cost of this project is $17,000,000. 
EXECUTIVE SUMMARY 
On July 25, 2017, the Commission authorized funding for the design, execution of a
procurement contract and the use of Port crews for the Automated Screening Lanes (ASLs)
project at Seattle-Tacoma International Airport (Airport). This request authorizes construction
to complete the installation of the procured ASLs. 
In September staff selected Vanderlande Industries, Inc. through a competitive procurement to
provide the ASLs for this project and the International Arrivals Facility (IAF) project as well.
Design has now begun for the installation. As the project has developed, (now through 30%
design) staff now anticipates being able to complete the project within the existing authorized
amount of $17,000,000. The cost reduction is due to a number of factors including reduction in
the number of ASL lanes proposed for each checkpoint and deletion of checkpoint enclosure
walls. 
JUSTIFICATION 
The Airport has seen unprecedented growth, wait times and space requirements in passenger
traffic in the Airport's security queues. With security checkpoint queuing becoming one of the
main choke points for passengers at the Airport, an ASL conversion will increase checkpoint
efficiency, shorten queue lines and improve the overall customer experience.

ASLs have rapidly developed and expanded at other US airports, with Las Vegas McCarran
International Airport being the most recent. ASLs are demonstrating a measurable increase in
passenger throughput. TSA has been a partner in this project though no federal funds are
available to pay for it. Both Delta Air Lines and Alaska Airlines also support the installation of
these lanes at the airport's security checkpoints. 
DETAILS 
This project will upgrade Passenger Security Checkpoints 2, 3 and 5 in a phased approach, one
checkpoint at a time, taking security lanes out of service in pairs to install the ASL equipment. 
The new equipment will be integrated with the existing TSA X-Ray machines. The project will
install new electrical and data infrastructure and relocate existing equipment to make room for
the new lanes. Due to current limitations with respect to some screening, existing non-ASL
lanes will continue to be used at each checkpoint. This has reduced the number of ASL lanes
procured. 
ASLs are larger than the Airport's existing security checkpoint lanes. Security checkpoints will
need to be reconfigured in order for the ASLs to fit. Because the ASL lanes are larger, fewer
lanes can fit at each checkpoint. This has also reduced the number of ASL lanes procured. At
Checkpoint 2 the new layout will require a supervisor booth be replaced. Checkpoints 2 and 3
require relocation or replacement of private screening rooms as well. 
New security grills will be installed at checkpoint 2. The selected vendor has proposed an
equipment modification that will allow new security grilles to be used at the existing grille
location, thereby avoiding the need to provide additional checkpoint enclosure walls for offhours
security. 
ASL's will not be installed at checkpoint 1 or 4 due to the limited footprint and use. This project
budget will procure ASL lanes for the IAF project, however, the checkpoint and infrastructure
for the lanes will be constructed by the IAF team and not by this project. 
Scope of Work 
Work will include making modifications to the screening lanes to increase security effectiveness
and efficiency and improve passenger experience. These components include, but are not
limited to, the following: 
(1)   Install additional electrical power and data communications for the ASLs 
(2)   Relocate existing checkpoint X-Ray equipment into the ASLs 
(3)   Reposition existing checkpoint equipment to their new locations 
(4)   Make revisions to Checkpoint 2 security grills 
(5)   Relocate flight information displays, a directory, and an advertising display 
(6)   Construct new supervisor booths and private screening rooms

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not install the procured lanes at any of the checkpoints 
Cost Implications: $32,000 (initial cost for this project which would have to be expensed) 
Pros: 
(1) No additional capital cost 
Cons: 
(1) No additional efficiency or throughput at checkpoints 
(2) Most likely queue lines and congestion will stay similar or increase in size from our
current situation 
(3) Most likely require additional resources (expense) to manage queue and congestion
in the future 
(4) This would not achieve the airlines' goals of providing a better customer experience 
This is not the recommended alternative. 
Alternative 2  Only install lanes at checkpoint 5 
Cost Implications: $3,000,000 
Pros: 
(1) One checkpoint will be more efficient 
(2) Less capital cost 
Cons: 
(1) Limited efficiency through the other checkpoints 
(2) Most likely queue lines and congestion will stay similar or increase in size from our
current situation 
(3) Most likely require additional resources (expense) to manage queue and congestion
in the future for non ASL checkpoints

(4) This would not achieve all of the airlines' goals of providing a better customer
experience 
(5) SEA would be behind the curve in security screening technology and would not be
able to respond to the integration of CT technology as easily in the near future 
This is not the recommended alternative. 
Alternative 3  Provide ASLs across all three checkpoints in a phased approach 
Cost Implications: $17,000,000 
Pros: 
(1) Provides a much more noticeable increase in customer experience 
(2) Greater potential to decrease queue lines and congestion 
(3) Provides Airlines with their requested level of innovation at the checkpoint with
increased customer experience 
Cons: 
(1) Highest cost alternative 
This is the recommended alternative.

Annual Budget Status and Source of Funds 
The Automated Security Lane (CIP #C800920) was not included in the 2017-2021 capital budget
and plan of finance. The budget was transferred from the Aeronautical Allowance (CIP
#C800753), resulting in no net change to the capital budget. The funding source for this project
will be future revenue bonds. The airlines were briefed at the airport airline affairs committee
meeting on July 20, 2017, and a majority-in-interest (MII) vote ballot has been sent out.

ADDITIONAL BACKGROUND 
Checkpoint lines continue to get longer as passenger loads increase at airports nationwide. The
TSA and other agencies have been looking for solutions to keep up with the demand. An
innovation task force was established to foster innovation by integrating key stakeholders to
identify and demonstrate emerging solutions that increase security effectiveness and efficiency,
improve passenger experience and the flow of commerce, and deliver solutions that secure the
freedom of movement throughout the nation's transportation system. 
TSA has worked closely with airlines, airport authorities, and vendors to deploy 25 ASLs in 2016
across four large hub airports; Atlanta Hartsfield International Airport, Los Angeles International
Airport, Chicago O'Hare International Airport and Newark International Airport. In 2017 there
were additional installs, the latest of these being McCarran International Airport.
