SUBJECT:  Passenger Loading Bridge Replacement Project  Airline Realignment (C800467)
Amount of This Request: $1,570,000    Source of Funds: Existing revenue bonds 
Est. State and Local Taxes: $99,000     Est. Construction Jobs Generated: 13 
Total Project Cost: $14,850,000 
ACTION REQUESTED:
Request Port Commission authorization for the Chief Executive Officer to: (1) execute a contract
to purchase one new passenger loading bridge (PLB) for Gate B1; (2) execute contracts to
purchase proprietary and long-lead components required to refurbish one PLB at Gate B11; and
(3) advertise and execute one major works construction contract to install one new PLB at Gate
B1 and to refurbish one PLB at Gate B11 for the amount of $1,570,000. 
SYNOPSIS:
The Commission has been briefed on the Terminal Realignment program several times. This
project represents the continuation of the one-time realignment of air carrier operations that is
taking place at the Airport over the next two years and was included in the 2012-2016 capital
budget and plan of finance. 
Due to this realignment effort, two airlines are scheduled to begin operations at gates on
Concourse B where there is either not currently an existing PLB (Gate B1) or where there is a
PLB that is currently owned and maintained by another airline (Gate B11). This project will
install a new PLB at Gate B1 where one does not currently exist. It will also purchase and
refurbish the 23 year old, airline-owned PLB at Gate B11 thereby bringing it up to current code
and Airport PLB standard.
A previous request in the amount of $6,700,000 for the first phase of this work was approved by
the Commission on February 22, 2011, and included PLB design services, the purchase of new
PLBs, and the advertisement and execution of one major works contract to replace, refurbish and
relocate PLBs at Concourse D in support of the first stage of the overall airline gate reallocation
effort.

This request includes the Passenger Loading Bridge  Airline Realignment scope of work
located on Concourse B. The total cost of the Passenger Loading Bridge  Airline Realignment
project at Seattle-Tacoma International Airport (Airport) is $14,850,000.
This PLB installation and refurbishment construction procurement documents will require 6%
participation by small contractors and suppliers (SCS) as identified by the Office of Social
Responsibility. 
BACKGROUND: 
The previous authorization associated with this CIP requested approval for the PLB replacement,
refurbishment and relocation work at Concourse D. This project continues the next phase of
PLB Replacement  Airline Realignment work for the two affected gates at Concourse B. It
further advances the Airport's objective to standardize on John Bean Technologies
AeroTech/Jetway PLBs and components.
Approval for subsequent realignment PLB work at the North Satellite will be requested from the
Commission at a later time. 
PROJECT JUSTIFICATION: 
The work planned under this authorization represents the next phase in a time-critical sequence
supporting the broader airline realignment effort while also providing improved operational
flexibility and efficiency at the Airport.
PROJECT STATEMENT AND OBJECTIVES: 
Project Statement: 
In order to accommodate the airlines to be relocated under this phase of the airline realignment
effort, one new PLB will be installed at Gate B1 where there is not currently an existing PLB. In
addition, one PLB at Gate B11 that was manufactured in 1989 and is currently owned by
Continental / United Airlines will be purchased by the Airport and refurbished to extend its 
operational life for up to 20 more years. This PLB has been evaluated by Aviation Maintenance
and determined to be a good candidate for refurbishment as opposed to replacement. Given the
current economic climate, the refurbishment of PLBs becomes a more attractive option than
outright replacement since a PLB can be refurbished for approximately half the price of one PLB
replacement. 
Project Objectives: 
This project advances the Airport's goal of standardizing airport owned PLBs for a common
use environment.
The refurbishment of PLBs that have reached the end of their service life will result in
decreased maintenance costs while extending the useful life of the PLBs and thereby
allowing the Airport to more cost effectively provide upgraded equipment at more gates. 
Refurbishing PLBs instead of replacing them keeps approximately 20 tons of demolition
debris per refurbished PLB out of the waste stream.

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
approximately $12,600 per PLB per year or a total of $25,200 for the first year plus an estimated
3% inflation escalation thereafter. These values include labor and materials, and are estimated
based upon actual costs from 2011 for similar newer Port-owned passenger loading bridges. The
labor portion of the operating and maintenance costs for these two bridges may not reach the
level indicated above because maintenance may not add staff when these two bridges are
activated. Through multiple elements of the Airline Realignment Project, seven passenger
loading bridges will be added to the list of PLB assets maintained by the Port by early 2013. As
workload is increased with the addition of these assets, staffing additions will eventually be
required. Through the utilization of continuous process improvement efforts, the addition of staff

may be able to be delayed for at least a portion if not all of these PLB assets. The additional
Airport costs are offset by the lower operating and maintenance costs realized by the
airlines. The airlines will save operational costs because they are no longer paying to maintain
the PLB assets. Rather they are shifting the maintenance costs to the Airport and they ultimately
pay for the PLB maintenance through Airport rates and charges. The Airport will efficiently
centralize the work to optimize the overall costs and will continue to pursue continuous process
improvements to improve efficiency. STRATEGIC OBJECTIVES: 
By providing improved PLBs, this project supports the Port's strategic objectives to:Ensure 
Airport vitality by providing airlines with reliable and efficient gate services. 
Lead the U.S. airport industry in environmental innovation and minimize the Airport's
environmental impacts.
ENVIRONMENTAL SUSTAINABILITY: 
This project will install new equipment at one gate and refurbish the existing PLB at one gate to
replace aging, less energy efficient equipment. Refurbishing PLBs instead of replacing them
prevents up to 20 tons of demolition debris per bridge from entering the waste stream. New and
refurbished PLBs employ the use of advanced electronics, materials and finishes that provide
enhanced energy efficiency and improved air quality through: 
Installation of EnergyStar compliant equipment/components where applicable. 
Use of up to 30% pre-consumer recycled content in PLB flooring. 
Use of repurposed rubber from used aircraft tires for PLB control cab drive wheel
assemblies. 
Use of No/Low VOC paints, adhesives and finishes wherever possible.
Use of LED light fixture lamps in place of fluorescent lamps. 
Provision for increased passive ventilation in newly manufactured PLBs over older models. 
BUSINESS PLAN OBJECTIVES: 
The aeronautical business strategy aims to strike a right balance between meeting the needs of
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 cost to the airlines. The use of technology and
thoughtful long term planning are key elements to this strategy.
Installation of new PLBs and the refurbishment of aging PLBs will provide reliable, high quality
facilities for passengers and airlines. This translates into reduced overall maintenance costs,
increased operational reliability and deferred future capital expenditures. 
The Passenger Loading Bridge Replacement Project  Airline Realignment supports the
Airport's Strategies and Objectives, namely: 
'Ensure Airport and Seaport Viability' 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 resources.

COMMISSION AGENDA

'Operating a world class airport' by managing our assets to minimize the long term cost of
ownership. 
TRIPLE BOTTOM LINE: 
This project demonstrates environmental sustainability by replacing outdated, inefficient and
unreliable PLBs and refurbishing viable existing PLBs. This will allow the Port to provide our
tenants and the general public with the updated, dependable and more efficient equipment that
they need to support and grow their business. The resulting improvement to the Port's PLB
inventory will promote net operating income through ongoing gate leases to airlines with a
corresponding decrease in maintenance and capital expenditures. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative #1: Replace one PLB and refurbish one PLB at Concourse B in support of the
ongoing airline realignment effort. Installation of a new PLB at Gate B1 where no PLB
currently exists will provide greater flexibility of gate operations and allow for better and more
efficient utilization of the Airport's existing facilities. Refurbishing the aging PLB at Gate B11
is a cost effective alternative to outright replacement, will provide a like new appearance
accompanied by approximately 20 years of additional service life. This is the preferred
alternative. 
Alternative #2: Continue to operate existing PLBs at Concourse B in their current configuration.
Frontier Airlines is scheduled to be assigned to gate B1 in the realignment. Without a new PLB
added to Gate B1, their operation cannot be accommodated. The PLB at gate B11 is currently
owned and maintained by United/Continental. They will be relocated to Concourse A with the
realignment and thus have no interest in owning and maintaining the B11 PLB. Hawaiian
Airlines will be utilizing gate B11 after the realignment. Delaying the refurbishment of the PLB
at Gate B11 will result in ever increasing maintenance costs, gate downtime and the risk of total
PLB failure. When a PLB fails the affected gate position cannot be used to its fullest potential
until repaired or replaced, both at considerable cost to the Port and significant impact to airline
operations. This in turn would result in lost revenue, reduced ability to accommodate flights and
would negatively impact major tenants by forcing airlines to possibly ground load passengers.
This is not the preferred alternative.
