EXECUTIVE SUMMARY
The 2024 Airfield Projects – Contract 3 is comprised of two interdependent Capital
Improvement Projects (CIPs) noted above. The two projects have overlapping work areas and
design functionality, interdependent operational impacts, and share 2024 schedule milestones.
As such, they are being planned, designed, and phased to be delivered concurrently for the
purposes of Airfield safety and efficiency, while minimizing operational impacts. 
The below table details the CIPs, corresponding authorizations requested, total authorizations
to date, and the total estimated project cost for each CIP.

JUSTIFICATION
The two projects being co-delivered via the 2024 Airfield Projects – Contract 3 consist of a
variety of physically and functionally interdependent Capital Improvements designed to ensure
continued operational safety and security and  meet SEA’s regulatory requirements. The
purpose of each project (CIP) is summarized below:
•    The PAGE project will reduce the risk of unauthorized fence and gate intrusions. This
project will also meet Port Security Standards to comply with our Airport Security
Program (ASP) and Transportation Security Regulations by increasing the height of the
defined Perimeter fence. 
•    The  Perimeter  Intrusion  Detection  System  (PIDS)  project  will  enhance  the  airport
perimeter security to ensure public safety and improve operational efficiencies through
use of technology and automation. PIDS Phase 2 enable PIDS to meet the operational
and functional requirements by reducing nuisance alarms on high usage gates via Access
Control.
Diversity in Contracting 
Through the Diversity in Contracting program, a Women and Minority Business Enterprise
(WMBE) aspirational goal will be established  and included  in the procurement of this
construction contract.
DETAILS 
These projects will interface with other projects and airfield operations. Continual coordination
with Airport Operations, Airlines, and related Tenants will ensure the least possible operational
impact during construction.
A project labor agreement will be used for these projects based on the importance of labor
continuity and the need to minimize any risk of impact to operations during construction.

Meeting Date: November 14, 2023
Scope of Work
The PAGE project will automate three Airport Operations Area (AOA) perimeter vehicle access
gates and install access control systems, cameras, and lighting; replace three seven foot gates
with 12 feet gates and upgrade outdated equipment at the gates; replace perimeter fence and
signage to comply with Port standards; and install razor wire on existing perimeter fence along
the AOA perimeter. 
The PIDS Phase 2 will install access control systems to two AOA perimeter gates so that
personnel accessing the AOA area can be identified via technology, reducing nuisance alarms.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Proceed with only the PAGE project scope. Do not proceed with the project
scope in PIDS Phase 2 which includes installing access control to two Gates. 
Cost Implications: $3,116,000 in Capital Cost for Perimeter Access and Gate Enhancements 
Pros:
(1)   Reduced capital spending in 2024. 
(2)   Reduced construction impacts to airport/airline operations in 2024.
(3)   Meets Ports Security Standards to comply with our Airport Security Program (ASP) and
Transportation Security Regulations.
Cons:
(1)   Requires PIDS Phase 2 to be handled as a separate effort.

Meeting Date: November 14, 2023
(2)   Does increase the risk of added cost to install access control at the two gates through
a future project.
This is not the recommended alternative.
Alternative 2 – Construct each individual project with separate construction contracts.
Cost Implications: An estimated $4,083,000 in Capital Cost to deliver the projects via two major
construction contracts, $267,000 more than delivering via one major construction contract as
proposed by the recommended alternative. 
Pros:
(1)   Less complexity for budget tracking during construction.
Cons:
(1)   Additional labor costs for contractor on-boarding and mobilizations, double-project
ramp up and close out. 
(2)   Increased coordination required between overlapping projects.
(3)   Increased construction safety risk due to overlapping work areas.
(4)   Additional and recurring impacts to airfield operations.
(5)   Additional risk in less attractive contracts for bidders. 
This is not the recommended alternative. 
Alternative 3 – Move forward to construct both projects as a single coordinated effort. 
Cost Implications: $3,816,000.
Pros:
(1)   Reduces safety risks, minimizes operational impacts and increases efficiencies as
coordination and construction is managed as a single effort. 
(2)   Minimizes  time  to  completion,  limiting  exposure  to  future  cost  increases,  while
delivering benefits expeditiously. 
Cons:
(1)   Additional accounting complexity during construction.
This is the recommended alternative.

the 2023-2027 capital budget and plan of finance with a budget of $3,400,000. The funding
sources would be Airport Development Fund and revenue bonds.
The Perimeter Intrusion Detection System (PIDS) – (CIP 800844) project was included in the
2023-2027 capital budget and Plan of Finance for $28,500,000. The capital budget increase of
