SUBJECT:  SEA Perimeter Intrusion Detection System (PIDS) (CIP#800844) 
Amount of this request:               $6,625,000 
Total estimated project cost:         $28,645,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) increase the Perimeter
Intrusion Detection System (PIDS) project at Seattle-Tacoma International Airport (SEA) funding
by $18,645,000 for a total estimated project cost of $28,645,000; (2) expand the PIDS coverage
area; (3) execute contracts for required hardware, software, and technical vendor services,
license(s) and maintenance; (4) complete design (5) enter into reimbursable agreements with
the Federal Aviation Administration (FAA); and (6) execute contract(s) for up to ten years for
licenses, service, and maintenance fees estimated not-to-exceed $4,500,000, which will be paid
from the Aviation annual operating budget. The amount requested under this authorization is
$6,625,000 with an estimated total program cost of $28,645,000. 

EXECUTIVE SUMMARY 
Enhancements to our perimeter security have been identified as critical in ensuring public
safety  and  improving  operational  efficiencies  through  automation.  Evolving  the  people,
processes and technology to detect, analyze and enable rapid, coordinated responses to
intrusion(s) is a key objective of the AV Security Master Plan. 
In 2019, $3.5 million was authorized to deploy a technology-based solution for partial airfield
perimeter detection with minimal infrastructure. It included, under separate authorization, a
phase 2 using the remaining $6.5 million funded in the capital plan to increase perimeter
coverage with additional technology. Additional funding is requested under this authorization
for added scope to increase the coverage area and allow for a technical solution that extends
communication infrastructure along the perimeter footprint. 
This authorization includes funding for implementation of the PIDS technology solution and
design for power and communication infrastructure required for the initial perimeter security

coverage area. Authorization for construction will follow in a future Commission authorization
request anticipated for Q3 2022. 
Aviation Security, Information and Communication Technology (ICT), Aviation Maintenance
(AVM), and the Aviation Project Management Group (AV PMG) will collaborate to complete this
project. Funding for this project was included in the 2020-2024 capital budget and Plan of
Finance in the amount of $10,000,000 under CIP #C800844, Perimeter Intrusion Detection. The
capital budget increase of $18,500,000 will be transferred from the Aeronautical Allowance
#C800753, resulting in zero net change to the Aviation capital budget. 
JUSTIFICATION 
Diversity in Contracting 
Through the Diversity in Contracting (DC) program, a Women and Minority Business Enterprises
(WMBE) goal will be included in the professional services contract and any major works
contracting. 
DETAILS 
Enhancements to our perimeter security have been identified as critical in ensuring public
safety and improving operational efficiencies through automation. This project will deliver a 
new system that will be part of a layered protection strategy which incorporates people,
processes, and technology to decrease security risk and increase situational awareness. When
integrated with existing security systems, it will provide a comprehensive picture to security
and safety personnel and facilitate coordinated responses. 
Scope of Work 
The total project scope includes: 
(1) Procure and implement the chosen technology solution that is capable of monitoring
100% of the SEA Security perimeter. 
(2) Design,  procure  and  construct  electrical  and  communication  infrastructure  which
supports the technical solution around the initial airport perimeter coverage area. 
(3) Integrate the solution with existing security systems to provide a comprehensive picture
and operational efficiencies. 
(4) Provide licenses, professional and maintenance services.
