MEMORANDUM 
COMMISSION AGENDA             Item No.      6b 
Date of Meeting    January 25, 2011 

DATE:    January 18, 2011 
TO:     Tay Yoshitani, Chief Executive Officer 
FROM:    Michael Ehl, Director Airport Operations 
Wayne Grotheer, Director, Aviation Capital Improvement Program 
SUBJECT:  Concourse D Common Use Expansion Project (C800455) 
Amount of This Request: $4,250,000        Source of Funds: Airport Development
Fund and/or existing 2010 bond proceeds 
State and Local Taxes Paid: $184,000       Jobs Created: 31 
Total Project Cost: $4,250,000 
ACTION REQUESTED: 
Request Port Commission authorization for the Chief Executive Officer to: (1) move forward
with completing design of the Concourse D Common Use Expansion project at Seattle-Tacoma
International Airport as outlined in this memorandum; (2) advertise and execute a major
construction contract; (3) execute contracts to purchase seating and passenger processing
equipment; (4) execute and/or amend software and maintenance contracts for the Concourse D
Common Use Expansion project; and (5) and utilize Port Crews for abatement and other work.
The total amount of this request is $4,250,000. The total projected program cost is also
$4,250,000. This request seeks a single Commission authorization to move forward with design,
advertisement and execution of a major construction contract. 
SYNOPSIS: 
This project is the beginning phase of a comprehensive reallocation of air carrier operations that
will take place at the Airport over the next two years. The air carriers are pursuing an aggressive
schedule for their reallocation project and have asked that we complete conversion of Concourse
D to common use by the end of 2011, thus driving the need to expedite the project and request a
single authorization now for design, advertisement and construction.
The Airport has installed common use passenger processing equipment at several locations that
can be used interchangeably by participating airlines as a flexibility and cost-savings initiative.
Several different airlines may share these common-use facilities, thereby deferring costly major

capital facility development. This affords the Airport the ability to accommodate more
passengers and support future enplanement growth within the current terminal footprint.
This project develops Concourse D into a common-use capable environment with the latest
common use processing equipment and technology. This project also updates gate and boarding
podiums to a new Airport standard, installs new carpet, new wall coverings and task lighting,
provides Airport standard gate seating and relocates gate podiums locations closer to the
passenger loading bridge doors.
This authorization will provide for design by outside professional services under an IDIQ
contract, allow the Port to advertise and execute a major construction contract, assuming there
are no bid irregularities, authorize use of Port Crews to perform work on the project; and
purchase seating and selected passenger processing equipment as a single authorization.
BACKGROUND: 
In the current Signatory Lease and Operating Agreement (SLOA), there is provision for a One-
Time airline Reallocation allowing the Airport to reassign airline operations areas for better
utilization of the existing facility. The Airport has issued a notice of intent to exercise the One-
Time Reallocation to support airline consolidation interests to maximize operational efficiency,
and the Port and airlines' mutual interest in deferring significant capital expansion costs. 
The reallocation calls for a number of gate reassignments including the conversion of Concourse
D from Alaska Airlines proprietary gates to a concourse that can accommodate various other
carriers. Converting Concourse D to a common use environment will satisfy the short-term as
well as the long-term needs for gate flexibility. Installation of common use passenger processing
equipment on Concourse D is a critical first step in supporting the movements of the other
airlines and gaining operational efficiency. As such, there is concerted emphasis on expediting
this project. This request seeks a single Commission approval action for authorization for the
project, so we can move forward with design, and advertisement and execution of major
construction contract because we need to expedite completion of this project ahead of the
relocation of new airlines to this concourse. 
PROJECT JUSTIFICATION: 
Project Objectives: 
Minimize the air carriers' costs as they relocate within the existing terminal facilities. 
Allow air carriers to grow and shrink in the marketplace without reinvesting in facilities. 
Enable the Airport to gain secondary user rights on gates with common use equipment.
This provides more flexibility to maximize the use of each gate and prevents new facility
investments every time a flight is added. 
Optimize location of check in and boarding equipment so that airlines can spend fewer
resources to manage each departure. 
Increase passenger flow and improve agent sightlines.

Lifecycle Cost and Savings: 
Port Information & Communication Technology and Aviation Maintenance expenses are
estimated to increase $115,000 annually. 
ENVIRONMENT AND SUSTAINABILITY:
This project demonstrates environmental sustainability by improving existing Port assets and
better utilizing existing resources. This common-use equipment will facilitate greater utilization
of the Concourse D gates. This reduces the potential environmental impact of major new
construction.
STRATEGIC OBJECTIVES: 
The Concourse D 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 greater facility

flexibility. Flexible gate operations will allow for greater utilization of the Airport's existing
facilities. 
Air carriers have continually vied for increased market share since the passage of the Airline
Deregulation Act of 1978. This drives constant change in their facility requirements. Creating a
flexible, common-use environment allows carriers and the Airport to spend fewer capital dollars
recreating facilities as market conditions change. More carriers are able to share the same
facilities without constant redesign and construction to customize the operating environment to
their specific proprietary needs. This also increases total Airport through-put rates, in a finite
sized terminal, as passenger volumes increase. 
BUSINESS PLAN OBJECTIVES: 
The Aeronautical business strategy aims to strike the right balance between meeting the needs of
our airline customers and the traveling public through cost effective means. Minimizing new
construction by making new operational improvements with technology helps to minimize costs
to the airlines. The use of technology and thoughtful long-term planning are key elements of the
strategy. 
TRIPLE BOTTOM LINE SUMMARY: 
This project standardizes Concourse D gate amenities and gives the airlines opportunities to
operate their boarding and check-in operations more efficiently. The traveling community will
benefit from an increased processing rate. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
1.  The recommended action is to provide the latest technology common-use environment
at all Concourse D gates to optimize flexibility and accommodate growth and irregular
operations by all carriers that use these facilities. 
2.  The Alaska Airlines proprietary communications technology could remain as-is, resulting
in a limited gating environment. This would not allow other carriers to use the gates, nor
would they benefit from the flexibility of a new common use environment for growth and
irregular operations. This is not recommended. 
3.  Provide new proprietary communications technology for each air carrier as they relocate
to Concourse D gates. This would conflict with the Airport's initiative to optimize
flexibility in gate operations and would require significant investment in construction
costs as airlines grow or modify their operations. This is not recommended.
