COMMISSION AGENDA             Item No.      5b 
ACTION ITEM             Date of Meeting    April 24, 2012 

DATE:    April 13, 2012 
TO:     Tay Yoshitani, Chief Executive Officer 
FROM:    Michael Ehl, Director, Airport Operations 
Wayne Grotheer, Director, Aviation Project Management Group 
SUBJECT:  Passenger Loading Bridges at Seattle-Tacoma International Airport (C800105) 
Amount of This Request: $656,000         Source of Funds: Existing revenue bonds 
Est. State and Local Taxes: $42,000         Est. Construction Jobs Generated: 6 
Total Project Cost: $6,000,000 (no change from original) 
ACTION REQUESTED:
Request Port Commission authorization for the Chief Executive Officer to: (1) expand the scope
of work to cover refurbishment of one passenger loading bridge (PLB) to be installed at Gate S8;
(2) prepare design documents; (3) authorize Port Construction Services (PCS) to self-perform
work; and (4) advertise and execute one major works construction contract to refurbish one Portof-Seattle-owned
PLB formerly located at Gate S10 and reinstall it at Gate S8. No new funding
is required to complete this refurbishment. 
SYNOPSIS:
This request will refurbish a Port owned PLB currently in storage and replace the PLB at Gate
S8 owned by Delta Air Lines. Gate S8 recently experienced catastrophic failure and was out of
service for eight days while awaiting replacement parts. International, wide-body flights needed
to be reassigned to other gates while S8 was inoperative at considerable inconvenience to the
Airport and various airlines. Due to its age, configuration and current mechanical condition, the
existing Delta-Air-Lines-owned PLB at Gate S8 is not considered to be a candidate for
refurbishment by the manufacturer (John Bean Technologies - JBT AeroTech/Jetway). 
This request is part of the Airport's plan to standardize PLBs for a common use environment and
will complete the PLB work that has taken place under Capital Improvement Project (CIP) 
C800105 since it was initially authorized by the Commission in July 2007 to include the
purchase and replacement of up to six PLBs. Under this CIP, seven PLBs have been replaced
and one existing PLB has been relocated to a new gate. PLB component purchases will utilize
an existing competition waiver allowing for sole source procurement of these items.
Approximately $680,000 of previously authorized funding remains despite this expanded scope.

This project is included in the 2012-2016 Capital Budget and Plan of Finance within CIP
#C800105. 
Staff has determined that these remaining funds will be sufficient to refurbish the Port-owned
PLB that was removed from Gate S10 in December 2011. After refurbishment, this bridge will
be installed at Gate S8 to replace the existing PLB currently owned by Delta Air Lines. The
existing PLB at Gate S8 was manufactured and installed in 1971 and its operational condition
continues to deteriorate.
Delta Air Lines' corporate management has formally notified Aviation Operations of their
willingness to remove and dispose of their PLB at Gate S8 if the Port will replace it with this
refurbished bridge. 
BACKGROUND: 
The primary objectives of CIP C800105 were twofold; to purchase and replace aging airlineowned
loading bridges and to replace Port-owned loading bridges that were deemed to be at the
end of their operational lives.
After it was removed from the South Satellite in December 2011, the former S10 PLB and
associated components were preserved to protect them from the elements and are currently being
stored at an unused Port-owned parking facility south of the Airport. The intent is to refurbish
the PLB at this location, thus minimizing operational impacts at the South Satellite, and then
install it at Gate S8 after the existing PLB is removed and disposed of by Delta Air Lines.
Since 2008, this CIP has been responsible for replacing PLBs at Gates B5, B12, N7, S1, S2, S5, 
and S10 as well as relocating the PLB formerly located at Gate C3 to Gate B3.
PROJECT JUSTIFICATION: 
The work planned under this authorization supports the overall initiative by the Port to own and
maintain all PLBs in a common use environment while also providing improved operational
flexibility and efficiency at the Airport.
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 diverts approximately 20 tons of demolition
debris per refurbished PLB from the waste stream.
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
This scope of work will take place in the parking area formerly used for the South Terminal
Expansion Project and at the South Satellite and includes:

Lifecycle Cost and Savings 
Annual operating and maintenance costs have been calculated by Aviation Maintenance at
approximately $12,600 per PLB per year plus an estimated 3% annual 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 this bridge may not reach the level indicated above because
maintenance may not add staff when this bridge is added to the Port inventory. 
Several passenger loading bridges will be added to the list of PLB assets maintained by the Port
by early 2013. As workload increases 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 new PLB
assets. 
STRATEGIC OBJECTIVES: 
By providing improved PLBs, this project supports the Port's strategic objective 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 refurbish and reinstall a surplus PLB at one gate to replace aging, less energy
efficient equipment. Refurbishing PLBs instead of replacing them diverts up to 20 tons of
demolition debris per bridge from entering the waste stream. 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. 
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.
Refurbishment of aging PLBs will provide reliable, high quality facilities for passengers and
airlines at low cost to the Port. This translates into reduced overall maintenance repair costs,
increased operational reliability and lower capital expenditures. 
This PLB project at the Airport project supports the Airport's Strategic Goal of operating a world
class airport by managing our assets to minimize the long-term cost of ownership. 
TRIPLE BOTTOM LINE SUMMARY: 
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: Refurbish the surplus, former S10 PLB and use it to replace the 41-year-old,
airline-owned PLB at Gate S8. Replacing the aging PLB at Gate S8 with a newly refurbished
bridge 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 the existing PLB at Gate S8 and leave the former S10 bridge
in storage as-is. The existing 41-year-old Delta-Air-Lines-owned PLB at Gate S8 recently
experienced catastrophic failure and was out of service for eight days while awaiting

replacement parts. When a PLB fails the affected gate position cannot be used to its fullest
potential until repaired, typically at substantial cost and significantly impact to airline operations.
This is especially true at the South Satellite where gates like S8 that are configured to
accommodate international, wide-body flights are in high demand. Should this PLB fail again,
this in turn would result in lost revenue, reduced ability to accommodate international, widebody
flights and would negatively affect major tenants by forcing them to relocate operations or
ground load passengers. This is not the preferred alternative.
