ACTION REQUESTED 
Request a single Commission authorization for the Chief Executive Officer to design, advertise
and execute a major works contract and execute a contract to purchase equipment to take two
existing gates at the South Satellite that are currently configured for domestic, narrow body
aircraft only and modify them to accept international, widebody aircraft operations. The amount
of this request is $4,850,000. 
SYNOPSIS
As international traffic grows at the Airport, the availability of gates suitable for international
wide-body aircraft operations at the South Satellite is becoming critical. Current flight schedules
during the noon peak at the South Satellite show that it is at capacity for widebody gates and
short of capacity for international gates.
The primary objective of this project is to reconfigure two existing gates that are currently used
for domestic, narrow-body aircraft operations only (Gates S4 and S6) and connect them to the
Airport's currentinternational arrivals facility by extending the International Corridor at the
South Satellite. One existing domestic, narrow-body aircraft gate will be deactivated (Gate S5)
which will allow Gates S3 and S6 to be configured to accept international, wide-body aircraft 
operations.
As Delta Air Lines and other international airlines increase international flights to Seattle this
year and next,  staff is requesting a single Commission authorization for the design,
advertisement and execution of a major works contract in order to connect one of the South
Satellite gates to the International Corridor before the 2015 summer travel peak.

BACKGROUND 
This work was originally included in the scope of the new International Arrivals Facility (IAF)
project; however, staff quickly recognized that the problem of inadequate international gating
capacity needed to be addressed sooner than the 2018 completion date currently anticipated for
the IAF project. Of the 14 gates at the South Satellite, 11 are currently capable of
accommodating international, wide-body  aircraft operations.  These gates connect arriving
international passengers to the U.S. Customs facilities via the international corridor, which is
located one level below the concourse level. When a departing or arriving international flight is
delayed, or if a gate becomes inoperative due to equipment problems, gate assignments need to
be reallocated quickly. 
International flights are predominantly operated by wide-body aircraft, and sometimes have to
hold on taxiways or remote parking areas until a suitable gate becomes available. This situation
was documented 12 times in 2013 with an average wait time of 27 minutes for the next available
gate. 
The summer 2014 scheduled flight activity will exceed the capacity of the existing facility. This
will require aircraft to be serviced on remote parking areas with passengers being bused to and
from the terminal. This  will lead to connection times longer than the currently published 90
minutes to connect between international and domestic flights. Such alternate procedures as
remote parking operations, implemented in conjunction with Customs and Border Protection
(CBP), Airport Operations, and the airlines to optimize the capacity of the current facility, are
not anticipated to keep pace with projected growth. Increased connection times risk potential
loss of market share to other West Coast airports with more modern international arrivals 
facilities. 
This project seeks to reduce the instances of holding aircraft off gate prior to unloading, as well
as the likelihood of hardstand unloading/loading operations or  displacing planes to other
Concourses for their departures.
These proposed modifications will significantly improve international  aircraft gating
opportunities and provide urgently needed flexibility in advance of the completion of the new
International Arrivals Facility in 2018. 
Under the provisions of the new airline signatory lease and agreement Section 6.5.1 (c), this
project is exempt from majority-in-interest (MII) approval by the signatory airlines. 
PROJECT JUSTIFICATION AND DETAILS 
The Port strives to provide appropriate gating options for international, wide-body aircraft
operations. Current traffic volumes combined with forecasted increases in international service
to and from the Airport mean that the gates capable of accommodating international arrivals and
departures are often booked at or beyond capacity.

COMMISSION AGENDA

This capacity shortfall in turn increases the likelihood that arriving international passengers will
have to hold onboard their aircraft for an extended period of time until a suitable gate becomes
available. In extreme cases, aircraft may be required to park on remote hardstands and bus
arriving international passengers to the South Satellite to clear U.S. customs or to split operations
and depart from another concourse at the Airport. 
Even with the addition of two more gates with access to the Airport's existing international
arrivals facility, the Airport will be approaching the Commission at a later date for action to
support hardstand busing operations according to forecasted increases in international flight 
volume in 2014 and beyond. 
Project Objectives 
The objectives of this project are: 
To provide increased gating options to international aircraft operations at the Airport. 
To minimize or eliminate hold time for arriving international aircraft while they await
access to an appropriate gate position. 
To minimize the need for remote hardstand or split operations. 
Scope of Work 
Design for this scope of work will be procured under one of the existing design services
IDIQ contracts 
Extend the international corridor (IC) at the South Satellite from Gate S3 to Gate S4 
Furnish and install a new passenger loading bridge (PLB) and fixed walkway at Gate
S4 that will connect to both the newly extended IC and the concourse levels 
Remove the existing PLB at Gate S6 and store it offsite for possible future
use/refurbishment 
Deactivate Gate S5 and relocate the existing PLB at Gate S5 to Gate S6 
Connect the Gate S5/S6 terminal node to the newly extended IC at Gate S4 using a
series of enclosed, temporary fixed walkways 
Purchase and installation of new PLB, fixed walkways and associated components
along with necessary architectural, electrical, data and mechanical infrastructure
upgrades to meet new standards and current building code requirements
Due to timeliness requirements, the new PLB, fixed walkways and associated
components will be purchased by the Port and provided to the contractor as ownerfurnished
equipment.

Lifecycle Cost and Savings 
Aviation Maintenance completes regular preventive, corrective and emergency maintenance on
all Port-owned PLBs, as well as provides customer service support for operations. Aviation
Maintenance estimates a current annual cost per PLB of approximately $20,000 inclusive of all
repair, maintenance and customer support activities, including 24/7  response.  Aviation
Maintenance does not anticipate adding or reducing staff or increasing or reducing budget to
support these PLB assets. Facility-wide, other PLBs are being added or removed from service as
components of other projects. Aviation Maintenance will be reallocating resources to adjust for
the changes to the assets affected by this project. 
STRATEGIES AND OBJECTIVES 
This project will support the Port's Century Agenda objectives of making Seattle-Tacoma
International Airport the West Coast 'Gateway of Choice' for international travel and of meeting
the region's air transportation needs atthe Airport for the next 25 years by providing critically
needed international gate capacity.
TRIPLE BOTTOM LINE 
Economic Development 
This project will allow the Port to provide our airline tenants and the traveling public with the
increased international aircraft and wide-body gating capacity they need to support and grow
their businesses. This in turn will provide additional development and economic benefits to the
region through increased international travel and business opportunities.
Environmental Responsibility 
This project will install a new PLB at the South Satellite to replace aging, less energy efficient
equipment. A system of surface mounted, temporary fixed walkways will also be installed to
connect Gate S6 to the International Corridor, thereby eliminating the need to excavate the ramp
area for the installation of traditional foundations and footings.
New PLBs employ the use of advanced electronics, materials and finishes that provide enhanced
energy efficiency and improved air quality through: 
Use of EnergyStar compliant equipment/components where applicable 
Use of up to 30% pre-consumer recycled content in the PLB flooring 
Use of repurposed rubber from aircraft tires for the PLB cab wheels 
Use of environmentally friendly adhesives and coatings where possible 
Use of energy efficient LED light fixtures in place of existing fluorescent fixtures 
Provision of increased passive ventilation in PLBs and fixed walkways

Community Benefits 
In addition to the increase in economic benefits to the region through increased international
travel and business opportunities, small contractors and suppliers will gain from increased
opportunities, in accordance with Small Business Resolution No. 3618, to work at the Airport as
a result of this scope of work. Increased international gates will also improve the Airport's
reputation by being able to better accommodate the international traffic and growth we are
encouraging and forecasting. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Wait until the new International Arrivals Facility (IAF) is under contract for
construction and include these modifications in that scope of work. Per the current schedule it
will be 2018 before this could be completed, during which time operational impacts to
international flight operations will continue and increase. This alternative will not address wait
times for arriving international flights during peak travel periods or the increased potential of
split or remote hardstand operations until the IAF is completed in 2018. This is not the
recommended alternative. 
Alternative 2)  Provide new international arrivals processing capacity elsewhere at the Airport.
A suitable location for adding this type of capacity at one of the concourses or another facility at
the Airport would require further analysis.  This option would very likely take longer to
complete, be more costly and cause greater disruptions to ongoing flight operations. This option
makes no interim provisions for minimizing wait times or decreasing split or hardstand
operations. This is not the recommended alternative. 
Alternative 3)  Invest in an extension to the International Corridor to Gate S4 and provide a
temporary connection from the reconfigured Gate S6 to the International Corridor. This will
increase international, wide-body aircraft gating flexibility, as well as minimizing arriving
international aircraft hold times, the need for split operations and the number of flights having to 
arrive and depart from remote parking areas.  This is the recommended alternative.
