Meeting Date: July 10, 2018

The project was presented at the Airline Airport Affairs Committee (AAAC) meeting on May 18,
2017, and received a positive majority-in-interest (MII) vote in September 2017. Since this
time, the Port has worked with the Federal Aviation Administration (FAA) to secure a FAA
Airport Improvement Program (AIP) grant for a portion of the project. Consequently, an
additional MII vote is not needed as the airline rate based costs will likely be lower than the
original approval. Since this will be an AIP funded project, the Port will include goals for
Disadvantaged Business Enterprises (DBEs).
JUSTIFICATION
The Airport Operations Area (AOA) perimeter fence line is the primary physical barrier into the
secured areas of commercial airports. Over the past years, other airports have experienced
several nationally recognized breaches in security that included accessing the AOA by climbing
over a perimeter fence. Seattle-Tacoma International Airport has also experienced this type of
trespass. There is a recognized need to improve security by increasing the level of difficulty for
unauthorized access through the AOA perimeter fence.
After the event of 9/11, the Port of Seattle established a minimum fence height of twelve feet
for the AOA perimeter fence wherever permissible by the Federal Aviation Administration
(FAA). Portions of the perimeter fence have been replaced with the twelve foot fence over time
as construction projects moved fence lines. However, there are still areas with shorter fence
that need to be upgraded.
Agreements were signed in September 2017 between the Port and the Transportation Security
Administration (TSA). As required in the agreements, non-climbable fence needs to be installed
for areas having higher potential for intrusion such as adjacent to roadways or where buildings
are present.
DETAILS
Primary reasons for the cost increase are additional items identified during design including (1)
the installation of non-climbable fence for areas with a higher potential of intrusion such as
adjacent to roadways or where buildings are present, based on the modified agreement
between the Port and the TSA; (2) the installation of faster gate operating system for AOA
access gate E-160 to standardize gate operating device for higher operating speed and
reliability; (3) the replacement of related AOA access gates including E-165, E-170, E-175, E-145,
E-100, E-160, W-45, E-105, E-150, E-155 and E-180 and (4) the installation of security camera
system for identified AOA access gates by Security to comply with the current airport security
requirements.
Scope of Work
(1) Replace approximately 8,100 linear feet of seven-foot AOA perimeter fence with twelve-
foot fence plus one foot of barbed wire at the top. Approximately 6,500 linear feet out
of the 8,100 linear feet of fence will be replaced with non-climbable fence.
