ACTION REQUESTED 
Request a single Commission authorization for the Chief Executive Officer to (1) proceed with
design for the replacement of the passenger loading bridges (PLBs) at Gates S7 and S9 and the
installation of a new PLB and fixed walkway at Gate B4; (2) purchase three new PLBs and a
fixed walkway to provide as owner-furnished equipment; (3) advertise and execute a major
works construction contract for the work at Gates S7 and S9; and (4) use Port crews to perform
some site work at Gates S7 and S9 and to complete the installation of the new PLB and fixed
walkway at Gate B4 at Seattle-Tacoma International Airport. The amount of this request is
$2,950,000. 
SYNOPSIS 
This project aids Delta Airlines increased flight schedule this summer. Both Delta and Alaska
Airlines are increasing the number of their flights. This increased activity across the Airport
necessitates the operational use of every available aircraft position which in turn requires a new
PLB be installed at gates B4, S7, and S9. The PLB's at S7 and S9 will be converted from airline
to Airport ownership. All three gates will be Airport owned and maintained to help facilitate the
ability for more shared use by multiple airlines which in turn can allow more aircraft turns per
gate per day. As a result of an earlier Continuous Process Improvement Lean workshop to
improve maintenance work flow on PLBs, and due to the removal of other PLBs as part of other
projects, no additional Airport maintenance craft full-time-equivalent personal are necessary in
order to maintain these additional Airport owned bridges. 
Airline activity growth at the Airport is requiring the installation of a new PLB at Gate B4 and
the mitigation of the risks of failure for older PLBs at Gates S7 and S9. Currently Gate B4 does

not have a PLB as it was removed in 2003. The new PLB would be installed at the location of
the one previously removed. The existing PLBs at Gate S7 and S9 are airline owned, are over 25 
years old and have begun to experience significant electrical and control system problems. The
Port will purchase new PLBs for installation at Gates S7 and S9. 
While CIP C800543 is included in the 2014- 2018 capital budget and plan of finance, the need to
add a PLB to Gate B4 is new, and requires a budget transfer from another CIP (C800653) for
PLB renewal and replacement. The need to add a functioning PLB at B4 is due to another new
CIP (C800662) that will add a 12th wide body gate at the South Satellite with access to the
Federal Inspection Service area to accommodate the growth in international flights. The
conversion of a narrow body gate to a wide body gate results in the elimination of one gate. This
request for a single authorization for design, procurement and installation is needed to have this
additional gate in operation by June 2014 in time for the busy airline summer schedule. This
authorization includes three PLBs, however, any necessary aircraft fuel pit relocations to match
aircraft sizes will be covered by separate authorizations. 
BACKGROUND 
The passenger loading bridge at Gate B4 was removed in 2003, and there is infrastructure in
place to provide for a new PLB to be installed. The gate will serve regional flights and reduce
the demand on heavily used South Satellite gates. 
PLBs are considered to have a service life of 25 years before major refurbishment or replacement
is required. The PLBs at Gates S7 and S9 were manufactured and installed in 1983 and 1988
respectively. These PLBs have experienced significant electrical and control system problems
over the past 20 months which have made them mechanically unreliable and often difficult to
operate. 
These PLBs are airline-owned. While some maintenance has been performed by the airlines over
the past 25 years, none of the major technical/operational systems of either PLB have been
upgraded since the original installation. Port staff has inspected them and determined thatthey 
are beyond their useful life and are not candidates for refurbishment. 
In addition, replacement of the existing PLBs  would  take each gate out of service for
approximately three weeks compared to up to 12 weeks for a complete refurbishment, which is
operationally unacceptable. After assessment by staff it was determined that due to the high
demand for aircraft gates with access to the existing international arrivals facilities at the South
Satellite, the PLBs at Gate S7 and S9 are not considered to be a good candidate for in-place
refurbishment and recommend instead that the PLBs are replaced with new.
Therefore, this project will purchase new PLBs for installation at Gates S7 and S9 which would
become Port-owned at the completion of the project. The existing airline owned PLBs will be
removed by the airlines and this work is not part of this project.

PROJECT JUSTIFICATION AND DETAILS 
Delta Air Lines, in an effort to reduce its operational costs and improve bridge reliability has
requested that the Port replace the old, worn out PLBs at Gate S7 and S9 with new or refurbished
bridges that meet their operational needs. Delta has requested that S7, the oldest and least
reliable PLB, be replaced by June 1, 2014, to meet their projected flight schedule requirements. 
S9 will be replaced in the fall of 2014. Delta has also requested the installation of the PLB at
Gate B4, so regional flights can be serviced from this location. To accommodate the projected
flight schedule this bridge also needs to be installed by June 1, 2014.
This Delta request is consistent with the Airport's strategy of opportunistically acquiring airline
PLBs so that the Airport can maintain them to the same high standards to ensure operational
reliability. The operational failure of a PLB, whether airline-owned or Port owned, negatively
affects operations and airline service while significantly inconveniencing the traveling public.
Gates S7 and S9 are capable of accepting international wide body aircraft and provide access to
the South Satellite international arrivals facility. Having either of these bridges out of operation
for even a short period of time significantly impacts the Port's ability to safely and efficiently
accommodate international passenger operations at the South Satellite.
Project Objectives 
The objectives of this project are: 
To provide safe and reliable equipment at the Airport's gates. 
To minimize unplanned PLB and gate downtime. 
To improve the efficient use of Port owned PLBs. 
Scope of Work 
Design for this scope of work to be procured under the existing design services indefinite
delivery, indefinite quantity (IDIQ) contracts. 
Purchase and installation of new PLBs, associated fixed walkway and related components
at Gates B4, S7 and S9 along with necessary architectural, electrical, data and mechanical
infrastructure upgrades to meet new PLB standards and current code requirements.
Port Construction Services will perform work associated with preparing the foundations
for the PLB replacement and construction management services should this be required.
A small works contractor will be responsible for installing and commissioning the new
PLB and fixed walkway at B4, which will be provided as owner-furnished equipment.
A major construction contract will be issued for installation and commissioning of the
new PLBs at Gates S7 and S9. 
The new bridges will be connected to the Port's Facility Monitoring System so any
malfunction that shuts the bridge down will be promptly reported to Maintenance for
faster response.

Lifecycle Cost and Savings 
Aviation Maintenance completes regular preventive, corrective and emergency maintenance on
all Port-owned PLBs, as well as providing customer service support for operations. Aviation
Maintenance estimates a current annual cost per PLB of approximately $20,000 inclusive of all
repair, maintenance and customer support activities, including 24/7 response. Aviation
Maintenance does not anticipate adding staff to support these PLB's. Facility wide, other PLB's
are being removed from service as components of other projects. Aviation Maintenance will be
reallocating resources to absorb the additional assets generated by this project. 
STRATEGIES AND OBJECTIVES 
By replacing the airline-owned PLBs that are at the end of their useful operational life with new
Port-owned PLBs, this CIP advances the Port's strategic objectives of: 
Ensuring Airport vitality by providing airlines with reliable and efficient gate services 
Maximize asset utilization and high density development to achieve the highest
throughput in the lowest possible footprint, and to preserve longterm growth
capacity. 
Exhibit Environmental Stewardship through our Actions 
Conserve energy and other resources, and minimize pollution and waste in the
construction and operation of our facilities and delivery of our services. 
TRIPLE BOTTOM LINE 
Economic Development 
This project demonstrates environmental sustainability by replacing outdated, inefficient and
unreliable PLBs. This will allow the Port to provide its 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 repair and
capital expenditures.

Environmental Responsibility 
This project will install a new PLB, associated fixed walkway and related equipment to replace
aging, less energy efficient equipment at Gate S7 and S9 and install a new efficient PLB at gate
B4.
New PLBs employ the use of advanced electronics, materials and finishes that provide enhanced 
energy efficiency and improved air quality through: 
Installation of Energy Star compliant equipment/components where applicable. 
Use of up to 30% pre-consumer recycled content in PLB flooring. 
Use of repurposed rubber from spent aircraft tires for PLB control cab bogies (under-cab
assemblies) 
Use of No/Low VOC (volatile organic compound) 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 
This project supports the Aviation Division's strategic goal to operate a world-class international
Airport by providing safe and secure operations, anticipating and meeting the needs of our
tenants and passengers and by managing Port assets to minimize the long-term total cost of
ownership. Having an operationally reliable and aesthetically pleasing PLBs at Gate B4, S7 and
S9 are advantageous to the Port as the premier gateway to and from the Northwest. 
Community Involvement 
The Project Manager will work with the Office of Social Responsibility to determine small
business participation opportunities, in accordance with small business Resolution No. 3618. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1) Install a new PLB at Gate B4 and transfer ownership of the existing PLBs at
Gates S7 and S9 and continue to operation them As-Is.  Installing the PLB at Gate B4 will
provide operational flexibility for regional fights. H owever, not replacing the PLBs at Gates S7
and S9; which have an increasing trend of mechanical and electrical failures, will impact safety,
increase emergency maintenance costs, and risk higher PLB downtime. This would reduce the
Port'sability to accommodate international flights as well as result in lost revenue. This is not
the recommended alternative. 
Alternative 2) Do nothing.  This alternative would not provide operational flexibility for
regional flights. It would not mitigate the risk for PLB failure. This is not the recommended
alternative.

Alternative 3) Install a new PLB at B4 and replace the airline-owned PLBs at Gates S7 and S9. 
Installing the PLB at Gate B4 will provide operational flexibility for regional fights. Replacing 
the PLBs at Gates S7 and S9, which are at risk of future service interruptions, with new Portowned
PLBs  will provide safe, high quality facilities for Airport passengers, increased
operational reliability and take Gates S7 and S9 out of operation for the shortest period of time
possible. This is the recommended alternative.
