TO:        Stephen P. Metruck, Executive Director 
FROM:    Wayne Grotheer, Director, Aviation Project Management 
Wendy Reiter, Director, Aviation Security 
SUBJECT:  North Satellite Transit System (STS)  Employee Screening Design, Equipment
Purchase and Construction Authorization (CIP #C801153) 
Amount of this request:               $1,400,000 
Total estimated project cost:          $1,400,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) complete design, (2) execute
contracts for screening equipment, and (3) use Port crews and small works contracts for
construction in support of the North Satellite Transit System Employee Screening project at
Seattle-Tacoma International Airport, in the amount of $1,400,000. 
EXECUTIVE SUMMARY 
The North STS Employee Screening project will design and construct a new employee screening
location within the North Satellite Transit System (STS) station at the main terminal, allowing for
greater airport security and safety improvements for personnel arriving to work each day. This
project further enables the Port commitment made toward 100% employee screening by
replacing the existing central employee screening location with one that has space for advanced
screening technology. The project will improve safety by no longer requiring screened airport
personnel to walk through locations in the congested bagwell after screening. 
JUSTIFICATION 
This project supports the Port of Seattle goal of achieving 100% employee screening at Seattle-
Tacoma International Airport (SEA). Currently, many employees are entering the secure side of
the   airport through employee portals and employee screening checkpoints; however, the
equipment being used is not federally certified. The existing central screening location does not
provide the area needed to house the Transportation Security Administration (TSA) certified
equipment that the security department requires. The Baggage Optimization project will be
closing the existing pedestrian pathway in the bagwell outside of the Central Employee Screening

Checkpoint, this will prevent Northbound airport staff from reaching their daily work
assignments without undue travel routes. This project will facilitate the continued screening of 
employees at the STS level of the main terminal, while increasing the level of safety for both 
pedestrians and tug operators in the bagwell by limiting foot traffic. The Airline Realignment and
Checkpoint One relocation projects require the existing central screening location to be vacated 
in order to repurpose the space to a planned United Airlines baggage service office (BSO). The
addition of a screening position in the North STS will enable the airport to add security assets to
the space and allow for better overall security. The project will also install infrastructure in
support of this project which will increase the overall value of the space. 
Diversity in Contracting 
In partnership with the Diversity in Contracting department in outreach, this project will be
performed by Port Construction Services (PCS) and will utilize small works contracts that typically 
utilize women and minority owned business enterprises (WMBE) as primes. 
DETAILS 
The project will relocate central employee screening to the North STS and improve safety and
security for the airport. The project budget requested is $1.4 Million. The project will be designed
utilizing an existing Indefinite Delivery Indefinite Quantity (IDIQ) architectural firm. Capacity for
this design has been reserved in anticipation of approval. The project will utilize PCS and Aviation
Maintenance (AVM) resources to complete the installation of the equipment. The project has an
approved sole source competition waiver, which will be used to procure an Advanced Imaging
Technology (AIT) screening machine valued at approximately $385,000. The AIT is compliant with
the American with Disabilities Act (ADA), will allow screening for all personnel without need for
any additional accommodation, is TSA certified and complies with current federal guidelines. The
equipment will have a recurring maintenance contract, which will be budgeted within the
Aviation Security department's annual operating budget. 
Scope of Work 
The project will include the following key components: 
(1)   Installation of glass and drywall partition walls to establish a perimeter for the new
screening location; 
(2)   Equipment  such  as  AIT  screening  machine,  network  demark  cabinets,  electrical
distribution panel, LED lighting, cameras, and access controls; 
(3)   Infrastructure that supports the equipment; 
(4)   Relocates existing central screening x-ray equipment and casework; and 
(5)   Selection of exterior finishes will take into consideration that it is in a public facing and
high traffic location.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do nothing. 
Cost Implications: $0 
Pros: 
(1) No additional expenditure. 
(2) No impact to security operations. 
Cons: 
(1)   The equipment used would not be compliant with current federal TSA guidance. 
(2)   The safety of employees would remain unimproved. 
(3)   Airport personnel would be impacted by pedestrian tunnel closure as a result of the
Baggage Optimization project, this would increase their foot travel significantly. 
(4)   The  Airline  Realignment  and  Checkpoint  One  relocation  projects  would  need  to
establish a new location for the planned baggage service office relocation. 
This is not the recommended alternative. 
Alternative 2  Relocate the screening position without the new AIT equipment utilizing only
existing equipment. 
Cost Implications: $1M 
Pros: 
(1)   This improves employee safety reducing foot traffic in the bagwell operational space. 
(2)   Cost savings associated with procurement of the new equipment. 
(3)   No additional training for equipment operations necessary. 
(4)   This mitigates the impact of the Baggage Optimization pedestrian tunnel closure. 
(5)   This  allows  the  former  central  position  to  be  reallocated  enabling  the  Airline
Realignment and Checkpoint One projects to utilize the space for a future BSO. 
Cons: 
(1)   The screening room would not be compliant with current federal TSA guidelines which
could lead to future regulatory issues with the program.
