ACTION ITEM                            Date of Meeting       June 28, 2022 

DATE:     June 21, 2022 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Eileen Francisco, Director Aviation Project Management 
Wendy Reiter, Director Aviation Security 
SUBJECT:  Load Dock Employee Screening Design, Equipment Purchase, and Construction
Authorization (CIP# C801119)
Amount of this request:               $1,645,000 
Total estimated project cost:          $1,700,000 
ACTION REQUESTED 
Request a single Commission authorization for the Executive Director to (1) complete the design 
of the Load Dock Employee Screening project at Seattle-Tacoma International Airport, (2) execute
contracts to purchase screening equipment, and (3) use Port crews for construction. The total
project estimated cost is $1,700,000. 
EXECUTIVE SUMMARY
This project if constructed will deliver the necessary facilities to establish a higher level of
employee screening in the load dock area of the Airport. This project will also help advance safe
and secure operations by ensuring prohibited items are not brought into the sterile area through
the loading dock. An existing Indefinite Delivery Indefinite Quantity (IDIQ) contract will be utilized
for design, and Port Construction Services (PCS) will construct the project. To strengthen security
and improve operations surrounding deliveries and the screening of employees, the Load Dock
Employee Screening Project will serve as a vital conduit. The anticipated total project value is
$1.7 million. 
JUSTIFICATION
This project is required to meet the Airport’s goal of full employee screening. Currently, travel
through the Loading Dock is managed using the Airport’s Access Control system. However, while
deliveries are visually inspected, employees are not screened. Employee screening on the Load
Dock would be co-located with inspections of deliveries to provide screening for everything
transiting that space into the sterile area of the Airport, including employees, vendors,
contractors, and their personal items.

Meeting Date: June 28, 2022 
Diversity in Contracting 
The project staff intends to utilize an existing Indefinite Delivery Indefinite Quantity (IDIQ)
contract which has an established 16% WMBE goal associated with the design. In partnership
with the Diversity in Contracting department, this project will be performed by PCS and will utilize
small works contracts that typically utilize women and minority-owned business enterprises
(WMBE) as primes. 
DETAILS 
Scope of Work
The project will be designed utilizing an existing IDIQ architectural firm. The capacity for this
design has been reserved in anticipation of approval. The project will utilize PCS resources to
construct and complete the installation of the security equipment. The project will procure an
Advanced Imaging Technology (AIT) screening machine through a sole-sourced contract valued
at approximately $521,000. The AIT is compliant with the Americans with Disabilities Act (ADA),
will allow screening for all personnel without the 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. The project will also install an x-ray machine provided by the Port Security
team. 
The project will complete upgrades to the existing security cameras, lighting, and signage at the
Load Dock. Chain link fence and bollards will be installed around the perimeter of the Employee
Screening to protect the new security equipment, and a hazardous materials storage cage will be
relocated to accommodate the screening equipment placement.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1: Construct an employee screening site at the Load Dock including explosive trace
detection and a large scanner suitable for merchandise and goods materials inspections.
Cost implications: $9,500,000 
Pros:
(1) Most thorough screening option that provides complete screening for materials and
goods coming through the loading dock. 
(2) Merchandise will be going through a higher level of screening. 
Cons: 
(1) Most expensive option. 
(2) Takes up the most space and may not be able to fit without major infrastructure
modifications. 
(3) Will have the highest processing time. 
This is not the recommended alternative. 
Alternative 2: Provide stadium-style screening, with a walk-through metal detector and a table 
for hand-performed bag searches. 
Cost implications: $700,000 
Pros:
(1) Takes up less space. 
(2) Less initial capital investment. 
(3) Will provide a basic level of screening that will help achieve the Airport’s goal. 
(4) For employees and personal item screening. 
(5) Reduces the security risk, but not as much as the preferred alternative. 
Cons: 
(1) Not as thorough, more potential for human error. 
(2) Less efficient, subject to longer wait times, and decreased throughput.
(3) Increased number of hand screens/pat-downs.
(4) Does not meet the SEA Aviation Security Standard for Full Employee Screening 
This is not the recommended alternative 
Alternative 3: Construct an employee screening site at the loading dock, including an X-Ray
machine and an AIT (body scanner).
