SUBJECT:  South Satellite Common-Use Infrastructure Expansion at Seattle-Tacoma
International Airport (CIP C800276). 
Amount of This Request: $2,403,500       Source of Funds: Airport Development Fund 
State and Local Taxes Paid: $109,500      Jobs Created: 25 
ACTION REQUESTED: 
Request Port Commission authorization for the Chief Executive Officer to advertise and execute
a major construction contract and provide installation of computer hardware by Port staff for the
South Satellite Common-Use Infrastructure Expansion project at Seattle-Tacoma International
Airport (Airport), for $2,403,500 out of a total projected program cost of $2,909,500. 
SYNOPSIS: 
The Airport has installed "common-use" infrastructure and equipment at several locations in the
terminal, such as most international gate areas and ticket counters, that can be used
interchangeably by participating airlines as a productivity and cost-savings program. A flexible,
common-use environment allows more airlines to use existing terminal facilities without
reoccurring capital investment. The Airport is further able to handle more passengers and support
future growth within the current terminal footprint. This project brings common-use equipment
and infrastructure to gates at the South Satellite (SSAT). 
This project will install the Airport's new common-use infrastructure at nine SSAT gates 
preferentially leased by Delta Air Lines, and installs Port standard casework at gates S1, S7, S8
and S9, plus repositions gate podiums closer to passenger loading bridge doors. The original
scope of this project also included conversion of up to fourteen ticket counter positions to
common-use and installation of common-use computer equipment at three Concourse A gates.
That work has since been accomplished by other projects or deemed unnecessary in light of 
future airline realignment work. The budget has been adjusted downward by $608,500 to reflect
this reduced scope.

BACKGROUND: 
Delta Air Lines' (DL) consolidation of its flight operations at the SSAT has created efficiencies
for its growing international operations because the Federal Inspection Service (FIS) area is also
located at the SSAT. DL has also recently constructed a new VIP lounge for their passengers on
the roof of the South Satellite. The Port supports the DL consolidation, but this has driven the 
need for installation of common-use infrastructure and equipment at four additional SSAT gates. 
DL has preferentially leased nine mid and wide-body gates, but four of these still need to be
available for use by other international carriers, when the capacity (and access to the FIS) has
been exceeded at the Port-owned gates (S10, S11, S12, S15 and S16). 
The Port and the carriers are interested in creating additional operational efficiencies at the gates
in an ongoing effort to reduce airline operating costs. The project repositions podiums and back
screens to locations closer to the passenger loading bridge doors to support this goal. The carriers
can more effectively manage the boarding of a flight with gate agents that can perform multiple
tasks from a single workstation near the bridge door. 
PROJECT JUSTIFICATION: 
The purpose of this project is to facilitate an expansion of the Airport's common use
environment through a program of Port sponsored projects that will support operations, bring
gate podiums and ticket counters to Port standards and provide common use infrastructure.
Project Objectives: 
Increase utilization of existing SSAT gates while avoiding incremental major capital
investment. 
Support future international carrier growth. 
Allow operations to be handled without delays to arrivals and departures when current
capacity is exceeded. 
Update the gate podium facilities to match current Airport standards already in place at most 
SSAT gates. 
Increase efficiencies at gates by relocating podiums closer to the boarding doors. 
Expand a passenger processing system that maximizes flexibility, meets operational needs
and reduces airline costs. 
Reduce airline expenses through more efficient use of resources necessary to manage
boarding and check in processes. 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
At the completion of this project SSAT gates will be newly equipped with the following: 
Gates S-1, S-7, S-8, S-9 
New Port standard gate podium casework and backstand monitors repositioned closer to
boarding doors 
Common use equipment and infrastructure 
Updated task lighting and signs

change to business plan forecast as this project was
included. Asbestos abatement costs, depending on the
timing will cause a short term increase in CPE by
$.02 in 2012.
Lifecycle Cost and Savings: 
Operation and Maintenance expenses by Aviation Maintenance are anticipated to increase by
$30,000 annually. 
It is also anticipated that the implementation of this project will involve asbestos abatement. The 
current estimate is $300,000. The asbestos abatement costs will be charged to expense (as an
environmental remediation liability project) in the year the triggering event occurs. 
ENVIRONMENT AND SUSTAINABILITY:
This project demonstrates environmental sustainability by improving existing Port assets and
better utilizing existing resources thus reducing the potential environmental impact of new gate
construction.
STRATEGIC OBJECTIVES: 
The South Satellite Common Use Expansion project supports two of the Port's Strategies and
Objectives, notably: 
This project promotes the Port's strategic goals to "Ensure Airport and Seaport Vitality" and "Be
a Catalyst for Regional Transportation Solutions" by providing the airlines with the tools and
equipment to achieve on-time performance. Flexible infrastructure at gates will improve the
Airport's asset base since more airlines will be able to use existing facilities for their operations.

Creating a flexible common-use environment allows carriers and the Airport to spend fewer 
capital dollars recreating facilities as operational conditions change. Carriers are able to share the
same ticket counter and gate facilities, including passenger processing hardware, without
spending on redesign and construction to customize the operating environment for a single
airline's needs. This helps increase total Airport through-put rates, in the existing footprint of the 
terminal, as passenger volumes increase. 
BUSINESS PLAN OBJECTIVES: 
Installation of common-use infrastructure and equipment will facilitate greater utilization of 
SSAT international gates. This project will improve customer service and provide a means to
serve airlines in a less expensive way (than expanding the SSAT building envelope) which
minimizes the growth of cost per enplaned passenger. As future international growth occurs this 
will create significant economic benefits in Seattle and the greater Puget Sound area. 
TRIPLE BOTTOM LINE SUMMARY: 
This project standardizes gate amenities and gives the airlines opportunities to operate their gate 
operations more efficiently. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
1.     The recommended action is for the Port to provide a common-use environment at
the South Satellite, utilizing the latest technology, to optimize flexibility to
accommodate growth and irregular operations by all carriers that use these facilities. 
2.     Delta Air Lines could retain proprietary communications technology only at the
SSAT gates without addition of common use gates, resulting in a less flexible gating
environment. This will not allow other carriers to benefit from the flexibility of the
common use environment for growth or support irregular operations. 
3.     Expansion of the SSAT building to provide additional gates could be implemented
immediately, at high capital cost, to create adequate facilities to handle the irregular
operations and future growth of DL and other international carriers. It is expected that
this option would have little carrier support at this time.
