FROM:    Michael Ehl, Director Airport Operations 
Wayne Grotheer, Director, Aviation Capital Improvement Programs 
SUBJECT:  Passenger Loading Bridge Replacement Project  Airline Realignment (C800467) 
Amount of This Request: $6,700,000       Source of Funds: Airport Development Fund 
State and Local Taxes Paid: $420,000      Jobs Created: 13 
Total Estimated Cost of Project: $14,850,000 
ACTION REQUESTED: 
Request Port Commission authorization for the Chief Executive Officer to: 
(1) Proceed with design for the installation or refurbishment of approximately fifteen Passenger
Loading Bridges (PLBs) to be located at Concourse B, Concourse D and the North Satellite; 
(2) Purchase existing airline-owned PLBs when refurbishment rather than replacement is
appropriate or as negotiated with the airline; 
(3) Execute contracts to purchase up to five new PLBs with a future option to purchase
approximately ten additional PLBs; and 
(4) Advertise and execute one major construction contract to replace and/or refurbish up to five 
existing PLBs located on Concourse D at Gates D1 through D5.
The amount of this request is $6,700,000. The total cost of the Passenger Loading Bridge
Replacement  Airline Realignment project at Seattle-Tacoma International Airport (Airport) is
$14,850,000. This request seeks a single Commission authorization to move forward with
design, advertisement, and execution of a major construction contract for Gates D1 through D5
only. The execution of the remaining work will return for future authorizations. 
SYNOPSIS: 
This project is part of the one-time realignment of air carrier operations that will take place at the
Airport over the next several years. The air carriers involved in this realignment program are

pursuing an aggressive schedule in which they propose to occupy gates on Concourse D by early
2012. Due to this realignment, a number of airlines are scheduled to relocate operations to gates
with PLBs that are currently owned and maintained by another airline. This project would
replace airline-owned PLBs with Port-owned PLBs, simplifying operational and maintenance
concerns. 
In order to facilitate this relocation schedule, the new PLB work at Concourse D needs to be
expedited. We therefore request a single authorization at this time for the advertisement and
execution of a major construction contract for new PLBs for Gates D1 through D5 only.
Because they are not under the same time constraints, we will return to the Commission to
request authorization to advertise and execute the remaining PLB major construction contract for
the replacement and refurbishment work on Concourse B, Concourse D (Gates D7, D8 and D10) 
and the North Satellite after the completion of design. 
BACKGROUND: 
In the current Signatory Lease and Operating Agreement 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
Airline Reallocation to support airline consolidation, maximize operational efficiency, and meet
the Port and airlines' mutual interest in deferring significant capital expansion costs. 
A consequence of the reallocation is that several airlines will be relocating their gate operations
to gates with PLBs that are currently owned and maintained by other airlines. For example,
American Airlines, Frontier Airlines, and JetBlue Airways are slated to use gates with PLBs
presently owned by Alaska Airlines.
Decisions related to which bridges should be replaced versus purchased and refurbished will be
made following detailed mechanical inspections. This authorization request seeks a single
Commission approval action for a time critical portion of the project, the replacement of five
PLBs on Concourse D at Gates D1-D5, that will expedite completion of this portion of the
project ahead of the relocation of new airlines to this concourse. The design of non-time critical
PLBs elsewhere on Concourse D, Concourse B, and the North Satellite are within this
authorization, however the advertisement and construction work for these bridges will return to
Commission to seek authorization at a later date.
The airport currently has a total of 74 PLBs. The Airport currently owns 52. 48 of the 52 PLB's
are manufactured or supported by one manufacturer named John Bean Technologies (JBT)
Corporation. The airport is standardizing on JBT bridges over time to lower operating costs,
maintain warrantees, minimize parts inventory, streamline training of Airport maintenance staff,
and simplify operator training for both airline employees and their contracted ramp workers. As
a result any replacement PLB's will be procured from JBT. The Commission was notified of
this sole source procurement strategy on July 9th 2010. The current contract with JBT for

COMMISSION AGENDA

procurement will be in place through 2015. Obtaining option pricing for up to 15 bridges will
ensure good pricing from JBT. In addition the construction work associated with the removal of
old bridges, and the installation of new bridges will be publicly bid to ensure both opportunity
for local contractors and good competitive pricing for the Airport.
PROJECT JUSTIFICATION: 
The majority of work planned under this authorization represents a time critical component in
supporting the broader airline relocation effort while also providing improved operational
efficiency throughout the airport.
Project Objectives: 
Support the timely relocation of airlines 
Enable the Airport to gain more flexibility to maximize the use of each gate 
Extend the service life of eligible PLBs for several more years through refurbishment of
major components and systems to increase reliability and reduce maintenance costs 
Reduce the possibility of a carrier being assigned to a gate with a PLB owned by another
airline 
Advance the Port's goal of standardizing Port-provided amenities at all gates
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
The scope of work for this project includes the replacement or refurbishment of up to 15 PLBs.
This includes the replacement of existing foundations where necessary. Prior to determining
replacement versus refurbishment, a condition survey will be prepared by an independent
contractor. Refurbishment scope of work will include renewal and replacement of primary
systems, equipment, components and finishes in order to extend their useful life. Purchase of the
airline owned PLBs is included, as appropriate for the corresponding work. Design will be
completed using an existing previously authorized Indefinite Delivery Indefinite Quantity service
agreement for Passenger Loading Bridge Design Services. PLB procurement will utilize the
existing competition waiver allowing for sole source procurement from the manufacturer.

CPE Impact              CPE will increase by $.11 by 2014, but no
change to the business plan forecast as this
project was included. The airlines will
realize lower operating and maintenance
costs. 
Lifecycle Cost and Savings: 
Annual operating and maintenance costs have been calculated by Aviation Maintenance at
$33,046 per PLB per year or a total of $495,685 for the first year plus an estimated 3% inflation
escalation thereafter. Based upon actual costs for 2010 and budgeted costs for 2011 and beyond, 
additional future full time equivalent (FTE) staff members will be required to maintain the added
PLBs and the future FTE's are included within the cost identified above. The additional Airport 
costs offset the lower operating and maintenance costs realized by the airlines. The Airport will
efficiently centralize the work to optimize the overall costs, and will report the CPE cost shift
when communicating with the airlines.
ENVIRONMENT AND SUSTAINABILITY:
The new and refurbished PLBs will reduce the amount of man hours necessary for maintaining
and repairing PLBs that have reached or exceeded their optimum design life. The project will
facilitate greater utilization of gates throughout the Airport, thus reducing the potential need for, 
and the environmental impact of, major new and costly construction to increase the total number
of gates and associated holdrooms over time.
STRATEGIC OBJECTIVES: 
The Passenger Loading Bridge Replacement Project  Airline Realignment supports two of the
Port's Strategies and Objectives, notably:

COMMISSION AGENDA 
Tay Yoshitani, Chief Executive Officer 
February 11, 2011 
Page 6 of 7 

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 and more efficient 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, thereby driving nearly constant change in their facility requirements.
Creating a flexible, common-use environment allows carriers and the Airport to spend fewer
capital dollars remodeling facilities as market conditions change. More carriers are able to share
the same facilities without continual redesign and construction to customize the operating
environment to their specific proprietary needs. This also increases total Airport through-put
rates, within the existing terminal footprint, as passenger volumes continue to increase. 
BUSINESS PLAN OBJECTIVES: 
The aeronautical business strategy aims to strike a right balance between meeting the needs of
our airline customers and the traveling public through cost-effective means. Minimizing new
facilities construction requirements by making new operational improvements with up-to-date
equipment and 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 supports the Airport's initiative to standardize PLB equipment and provides the
flexibility the Airport needs to assign gates and to operate more efficiently. The traveling
community will also benefit from increased airline availability to modern, functional gate
equipment. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
ALTERNATIVE 1:  Replace or refurbish up to 15 PLBs as described in order to optimize gate
flexibility, alleviate conflict between ownership and user, accommodate growth, and add further
Port-owned PLBs into the inventory. Provide a single authorization to design, advertise and
award replacement or refurbishment of the PLBs at Gates D1-D5. We will return to the
Commission to request authorization to advertise and award the remaining PLB work on
Concourse B, Concourse D and the North Satellite Terminal after design has been completed and
per the scheduled provided. This is the recommended action.
ALTERNATIVE 2:  Do nothing: Leave the PLBs as-is and require airlines to negotiate new
ownership, or remove, and/or purchase PLBs for preferential gates. This would require
negotiation agreements with the airlines and would continue to complicate future moves. This
action is not recommended.

(revised) dated 12/02/2010 
PREVIOUS COMMISSION ACTION: 
On July 9th, 2010, the Commission was notified that the CEO would enter into a 5 year sole
source contract with JBT Corporation for PLB procurements, parts, and equipment. The airport
is standardizing on a single type of PLB. The justification memorandum attached to the July 9th 
notification outlined the benefits of the sole source contract that includes less inventory,
interoperability of parts, not voiding warrantees, standardizing training, and generally lowering
operating costs.
On January 25, 2011, the Commission was briefed on several projects, including this one, that
are part of the overall airline realignment program and which will require a single Commission
authorization in order to meet the realignment schedule. The first part of the realignment
program was authorized by the Commission on this date under the Concourse D Common Use
Expansion Project (C800455).
