ACTION ITEM                            Date of Meeting      January 22, 2019 
DATE:     January 10, 2019 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Wendy Reiter, Director Aviation Security 
SUBJECT:  Perimeter Intrusion Detection System (CIP #C800844) 
Amount of this request:               $3,520,000 
Total estimated project cost:         $10,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to authorize to (1) proceed with
the first phase  in  the Perimeter Intrusion Detection capital project  at Seattle-Tacoma
International Airport; (2) procure required hardware, software, vendor services, and license and
maintenance; and (3) use Port staff for implementation, for a total phase one cost not to
exceed $3,500,000 and estimated training of $20,000. A 10 -year contract for license and
maintenance fees is estimated at $420,000. 
EXECUTIVE SUMMARY 
The purpose of this authorization request is to create an additional security layer for portions of
the Airport perimeter using technology for continuous monitoring, threat assessment, and
alerts. This improved capability is an important part of the Aviation Security Plan. 
Perimeter detection systems include a range of technologies that provide reliable detection of
an intruder, and integrated with a video surveillance system, allow for visual verification and
assessment for appropriate security or operational response. Enhanced perimeter intrusion
detection  (PIDS)  at  Sea-Tac  airport  is  most  economically  provided  using  a  variety  of
technologies appropriate for the selected coverage areas. Radar or similar technology can cover
a large amount of the visible perimeter with centrally located detection devices. In areas with
visibility obstructions, integrated fencing systems will better meet security requirements. This
layered approach for perimeter security improvements will advance the Port's capabilitiesto
detect and analyze intrusion events and enable rapid, coordinated responses. 
The full PIDS capital budget includes scope to implement multiple technology solutions for
selected coverage areas. To maximize our investment, the solution will be delivered in two
phases. The scope of this initial phase includes the procurement and full implementation of
only the radar, or similar technology, intrusion detection system. Once the coverage  area for

the first phase is finalized, a second phase for fencing intrusion detection will be brought
forward for authorization. The authorization request for this initial phase includes no funding
for the planned second phase. 
Aviation Security, Information & Communication Technology (ICT), Aviation Maintenance
(AVM), and Port Construction Services (PCS) will collaborate to complete this project. Total cost
for this initial phase is estimated to be $3,520,000. Ten-year license and maintenance fees are
estimated at $420,000. Recurring license and maintenance costs will be budgeted within the
Aviation Maintenance department operating budget. The cost of both phases was included in
the 2019-2023 capital budget and plan of finance in the amount of $10,000,000. 
JUSTIFICATION 
Enhancements to our perimeter security have been identified as critical in ensuring public
safety and improving operational efficiencies through automation. The new system will be part
of a layered protection strategy that 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. 
The authorization for the first phase will provide for selected areas of the airport perimeter: 
(1)   Continuous monitoring for selected coverage areas. 
(2)   Algorithm-based threat assessment with the ability to proactively distinguish between
normal operations and a potential threat. 
(3)   Robust alerting capabilities. 
(4)   Directional tracking of potential intrusions enabling rapid responses to mitigate issues. 
DETAILS 
Scope of Work for First Phase 
(1)   Procure and implement a radar or similar technology solution to enhance perimeter
security for selected coverage areas. 
(2)   Integrate with existing security systems to provide a comprehensive picture and
operational efficiencies.

ALTERNATIVES AND IMPLICATIONS CONSIDERED FOR FIRST PHASE 
Alternative 1  Implement the Initial Phase of the Perimeter Intrusion Detection System 
Project 
Cost Implications: Phase One Cost: $3,520,000 + Operating Expense: $42,000 per year 
Pros: 
(1)   Provides  continuous  monitoring,  real-time  intrusion  alarms,  threat  assessment,
location and information for appropriate and coordinated security and operational
responses for selected coverage areas. 
(2)   Remote  location,  tracking,  identification  and  assessment  capability  for  multiple
business units that aids quicker response and resource coordination. 
(3)   Ability to respond rapidly and in a coordinated manner based on assessment of
intrusion. 
(4)   Additional data and robust reporting capabilities for post-incident assessment and
analysis of intrusion types. 
Cons: 
(1)   Capital funds are not available for other efforts. 
(2)   Requires an additional FTE to manage and maintain the system.
