ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to: (1) adjust scope to
reallocate the various elevators and escalators between Vertical Conveyance Modernization,
Aero Phase 1 and Phase 2 CIPs to best address operational concerns and coordinate with the
NorthSTAR program; (2) combine both Vertical Conveyance Modernization Aero Phase 1 and
Aero Phase 2 CIPs into a single CIP; and (3) advertise for bids and execute construction
contracts for the Vertical Conveyance Modernization, Aero Phase 1 including associated
regulated materials abatement and removal for a project total of $14,999,000. The combined
project total will be $24,556,408. 
SYNOPSIS 
The Airport has developed a renewal and replacement program for both the elevators and
escalators throughout the main terminal and satellites. Many of the elevators and escalators are
over 40 years old and are at the end of their service lives. The Vertical Conveyance
Modernization Aero projects will update old elevators and escalators over a two-year period. 
Passengers will benefit from this project by using faster, more reliable elevators and escalators.
A year ago, the Commission authorized the design and regulated materials abatement for the
Vertical Conveyance Modernization, Aero Phase 1 project. Concurrently, the Commission
authorized design and abatement for the Vertical Conveyance Modernization, Aero Phase 2
project. Subsequent to those authorizations, two elevators and four escalators at the North
Satellite, one elevator and four escalators at the end of Concourse C, along with associated
design funds, were transferred to the NorthSTAR program  in order to gain construction

efficiencies. Both of the Vertical Conveyance CIPs are included in the 2014  2018 capital
budget and plan of finance. 
The transfer of the above cited units to the NorthSTAR program, design delays resulting from
technical difficulties associated with the design of the two new elevators at South Satellite, and
ongoing operational/maintenance concerns necessitated a re-alignment of Aero Phase 1 project
elements. Combining the Aero Phase I and Aero Phase II CIPs into one CIP will facilitate
ongoing efficiencies in the management of this program. 
BACKGROUND 
The existing elevators included in this project were installed in the 1960's and 1970's and the 
existing escalators were installed in 1970 and upgraded in 1990. Due to their age and technology,
the controls, drives, and door actuators of these elevators and escalators have become
uneconomical to maintain. Two elevators in this project (SSAF and MT-2) are currently out of
service and cannot be repaired. The unavailability of the freight elevator (SSAF) is causing
problems such as having to move concessions goods through smaller passenger elevators. 
Installation of hydraulic oil cooling packages will improve the reliability of the existing
hydraulic elevators by eliminating or decreasing outages due to overheating, thus improving the
Airport's experience of passengers who are unable to use the stairs or escalators. 
Below is an updated listing of elevators and escalators in this authorization request:

Budget Status and Source of Funds 
This project (CIP #C800251) was included in the 2014-2018 capital budget and plan of finance 
with a budget of $13,502,211. A budget increase of $486,789 is due to the addition of one
additional hydraulic elevator oil cooling system as well as updated program support costs. The
funding sources will include existing revenue bonds and future revenue bonds. As explained in
connection with the 2014  2018 plan of finance, The Port plans to issue revenue bonds in 2014
to fund a number of projects included in the 2014-2018 capital budget. 
Vertical Conveyance Modernization Aero, Phase 2 (CIP #C800375) is also included in the 2014-
2018 capital budget and plan of finance with a budget of $8,834,408. This project will also be
funded by a combination of existing and future revenue bonds. 
Expense funds will be used for the regulated materials management major construction contract,
support/monitoring work performed by Port Construction Services, and the necessary nonwarranty
maintenance activity during the twelve-month warranty period for the seven elevators

Lifecycle Cost and Savings 
From a financial perspective, the Port will experience ongoing maintenance and periodic
component renewal. However, these are normal operations and maintenance costs, which are
expected to be offset to some degree by reduced repairs on an emergency and/or urgent repair
basis to aging existing vertical conveyance equipment. 
The primary benefit of the elevators in this project will be realized by inbound and outbound
passengers who are not able to use escalators. There will be increased availability of elevators for
these passengers. 
This project is in alignment with the Port's goal of improving the long-term sustainability of its
facilities and operations. This project will provide a generally positive effect on the environment
to the extent that modernized elevators and escalators will reduce the Airport's reliance on older
and less energy efficient vertical conveyances.

STRATEGIES AND OBJECTIVES 
This project contributes to accommodating the Port's Century Agenda Goal to meet the region's
air transportation needs at Sea-Tac Airport for the next 25 years. The project provides enhanced
capacity and flexibility in critical terminal vertical circulation infrastructure, complementing the
recently completed Terminal Escalator Modernization (44 escalators) project. 
TRIPLE BOTTOM LINE 
Economic Development 
This project will increase the long-term ability of the Airport to serve the airline industry's future
passenger growth. This project improves the efficiency of the existing systems and adds longterm
reliability before major component replacement is required.
The project manager will work with the Office of Social Responsibility to determine small
business participation opportunities, in accordance with the small business resolution 3618. 
The Commission previously authorized execution of a project labor agreement for the project. 
Environmental Responsibility 
The project demonstrates environmental sustainability by improving existing Port assets to
extend their life and better utilizing existing resources. In addition, the modernized escalators
will have the ability to go into sleep mode, further reducing energy demand during non-peak
passenger times. 
Community Benefits 
This project will increase the capacity of future Airlines growth. Long-term vitality of the
Airport benefits the regional economy, the local environment, and nearby communities. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Do nothing. This would not address the Airport's urgent need to return
inoperable elevators to service, and would continue placing increased demands on the remaining
operating elevators and escalators as well as inconveniencing the traveling public. This is not the
recommended alternative. 
Alternative 2)  Repair/modernize only those elevators that are inoperable plus those elevators
for which parts are no longer available. This alternative only delays the inevitable modernization
of the remaining elevators and escalators and exposes the Airport to costly emergency and/or
urgent repairs when breakdowns do occur. This is not the recommended alternative. 
Alternative 3)  Perform the modernizations to the elevators and escalators, upgrade the service
life of the vertical circulation components to realize the benefits of reliable equipment and the
energy savings resulting from the solid state controls and escalator sleep mode operations, and be
assured of the availability of maintenance and repair parts for the next foreseeable future. This is
the recommended alternative.
