SUBJECT:  Employee Security Screening Phase 2 (C800984) 
Amount of this request:               $1,425,000 
Total estimated project cost:           $7,900,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to proceed with design of the
Employee Security Screening Phase 2 project at Seattle-Tacoma International Airport. The
amount requested under this authorization is $1,425,000, out of a total estimated budget of
$7,900,000. 
EXECUTIVE SUMMARY 
This project will add vehicle and personnel security screening systems to airfield Gates E125
and E190. The project will construct facilities and procure equipment to provide screening of
airport personnel consistent with the employee screening program in the Terminal. The project
will also include screening of vehicles, by adding an under-vehicle screening system that will
detect any alterations to the vehicle used to hide weapons. Currently, these external gates only
conduct visual inspections of vehicles and people; this project will improve security. References
to employees in this memo refer to airport tenant employees and/or airport vendors, and their 
authorized vehicles used to conduct business Airside. 
An initial project budget, in the amount of $550,000, was included in the 2019  2023 capital
budget and plan of finance, utilizing the remaining balance of the Employee Security Screening
Phase 1 project in the Terminal. The  remaining balance was transferred for continued
utilization by the Employee Security Screening Program to be applied towards Phase 2 of the
project. A 15%-level of design has now been completed for the Employee Security Screening
Phase 2 project and the total estimated cost is $7,900,000. 
DIVERSITY IN CONTRACTING 
The project manager will work with the Diversity in Contracting department to determine
participation opportunities and set goals for women and minority business enterprises (WMBE)

attainment. These affirmative efforts are in accordance with the Policy Directive on Diversity in
Contracting. 
JUSTIFICATION 
This action satisfies the business plan to operate a world-class international airport by ensuring
safe and secure operations. The project will improve security operations and invest in new
facilities to remain in compliance with evolving federal directives and Transportation Security
Administration (TSA) requirements related to employee screening. Changes in federal security
requirements, resulting from events at other airports, have required increased attention to
screening operations. 
DETAILS 
Employee Security Screening Phase 2 will provide employee and vehicle screening to the
Airfield 
Employee screening equipment will be equal to screening technologies currently utilized
in the terminal 
Vehicle screening technology will be installed as part of this project 
This will lead us closer to 100% employee screening 
This project will enhance safe and secure operations inside and out of the airport 
Scope of Work 
The project will provide facilities with weather protection, and include discrete screening space 
for employees, as well as security screening equipment to add screening at existing Airfield
Gates E125 and E190. Excluded from the scope of work is Gate E45 for the reason that there is
not sufficient room to construct a facility in that area and the Gate may be relocated in the
future due to the lack of space for queuing vehicles. This gate has limited use in comparison to
the other gates. 
(1)   Build, or procure facilities complete with power, communications, and HVAC to screen
employees at the gates 
(2)   Provide security screening equipment, comparable to what is used in the terminal, to
screen employees at the gates 
(3)   Provide security screening equipment to screen under vehicles entering the Airfield

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Continue operations as they are today at the external gates. This only provides
visual screening inside the vehicles and no use of screening technologies for employees. 
Cost Implications: Expense for preliminary work $160,000 
Pros: 
(1)   No additional funding needed for the project 
(2)   No additional staffing needed 
Cons: 
(1)   This option fails to enhance safety and security 
(2)   This will not meet the Port of Seattle business plan to provide a safe environment for
our employees and customers 
This is not the recommended alternative. 
Alternative 2  Proceed with this project to screen employees without adding the under-vehicle
screening technology. 
Cost Implications: $7,210,000 
Pros: 
(1)   Reduction of cost for the program 
(2)   Minimal reduction of construction time and impacts 
Cons: 
(1)   Does not provide full screening of the vehicles 
(2)   Does not meet the Port of Seattle business plan to provide a safe environment for our
employees and customers 
(3)   Increases the time to get through the exterior gates 
(4)   Closing a gate during construction of the new facilities may have temporary impacts
by decreasing the entrances to the airfield 
(5)   Additional screening personnel (estimated 19 FTE) 
(6)   Additional cost for Aviation Maintenance to provide ongoing upkeep of new facility 
This is not the recommended alternative.
