SUBJECT:  Vertical Conveyance (Elevator) Modernization Project at Seattle-Tacoma
International Airport (CIP # C800251). 
Amount of This Request: $2,991,850    Source of Funds: Airport Development Fund and
Existing Revenue Bonds 
Total Project Cost: $11,120,000 
ACTION REQUESTED: 
Request Port Commission authorization to (1) prepare full design documents; (2) authorize Port
Construction Services (PCS) to perform Regulated Material Management (RMM) design and 
monitoring; and (3) bid and award a major construction contract for RMM abatement in existing
elevator shafts and related spaces for the Vertical Conveyance (Elevator) Modernization Project,
Aero Phase I Project (CIP# C800251) at Seattle-Tacoma International Airport (Airport) for
$2,991,850. The total project cost is $11,120,000. 
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 Phase I project, one of four individual projects in this program, will
incorporate complete elevator modernization upgrades for eight existing traction elevators and
for the addition of hydraulic oil cooling units to eleven existing hydraulic elevators in the Main
Terminal. The design work for this project will be accomplished utilizing a previously
authorized IDIQ contract. The total project cost is $11,120,000 (including $1,346,850 expense).
This request is to complete design of this elevator modernization project and to authorize the first
construction contract to remove regulated materials from all of these elevator shafts. Staff will
return in the spring to request the remaining funds and authorization to advertise and award the
follow-on construction contract for upgrading the elevators. The Port is evaluating whether it
will utilize a project labor agreement (PLA) for the RMM abatement work and/or the follow-on
elevator construction contract.

BACKGROUND: 
In 2000/2001 an airport-wide elevator modernization program was planned as part of the Airport
Modernization Program. However, the events of September 11, 2001, forced the Airport to
significantly scale back those plans. Of the 79 escalators and 80 elevators in the Airport 
terminal, only 12 elevators and six escalators have been modernized. Since 2001, additional
elevators and escalators have been identified for modernization or upgrades due to the increased
time in service. Currently the Terminal Escalator Modernization project ($55,000,000
authorized February 1, 2011) is modernizing 42 existing escalators throughout the Main
Terminal and South Satellite and installing two new escalators in the South Satellite. This
project (Aero Phase 1- $11,120,000) will modernize eight elevators and overhaul the hydraulics
of 11 existing elevators, which were all identified as the most critical to upgrade quickly. The
follow-on projects for next year (Aero Phase 2 - $17,227,000 and Non-Aero Phase 1 - 
$9,806,000) will modernize an additional 15 elevators and 12 escalators. After all of the above
projects are completed, 19 escalators and 34 elevators will remain at the terminal that have not
been upgraded; however, they are all less than 20 years old and have expected service lives of
five years or more remaining. The two follow-on projects for next year may be modified to
install new elevators or escalators for the South Satellite Federal Inspection Services mid-term
improvements and changes proposed by Alaska Air Group for the C Concourse, both of which
are now under study. 
The elevators included in this project were installed in 1970 and 1971. Due to their age and
technology, the controls, drives and door actuators of these elevators have become uneconomical
to maintain. In addition, the replaced systems, i.e., new motors and controls, would be more
efficient and meet current energy codes, resulting in energy savings.

STRATEGIC OBJECTIVES: 
Ensure Airport and Seaport Vitality 
The project provides enhanced capacity and flexibility in critical terminal infrastructure, both for
airline customers and for the Airport's concessionaire customers at both the South and North
Satellites. This project supports the Airport strategy that provides world-class facilities that
anticipate and provide for the needs of travelers and customers. 
Exhibit Environmental Stewardship through Our Actions 
This project is in alignment with the Port's goal of improving the long-term sustainability of its
facilities and operations. This project has a generally positive effect on the environment to the
extent that modernized elevators will reduce Airport reliance on less energy efficient vertical
conveyance alternatives and will allow more efficient movement of passengers and retail
product. Passengers and tenants will benefit from faster, more reliable elevators.

increase on a one-time basis by $.08 spread over two
years (approximately $.04 in 2012 and 2013) 
There are no anticipated increases in annual elevator O&M costs associated with this project.
ECONOMIC IMPACTS: 
The Port will spend less maintenance funds on emergency and/or urgent repairs to existing
vertical conveyance equipment. 
ENVIRONMENTAL SUSTAINABILITY/COMMUNITY BENEFITS: 
There are significant benefits with reductions in handling of concessionaire's retail product on
the ramp, as they will be able to use freight elevators, in lieu of service elevators or freight
elevators that are not co-located where their retail product is stored. Reduced ramp vehicular
traffic will result in lower fuel consumption and therefore less carbon air emissions.

TRIPLE BOTTOM LINE SUMMARY: 
This project will provide tangible improvements to the Airport's vertical circulation capability. 
Passengers will be able to depend on reliable vertical circulation means to safely and quickly
move between floors in the South Satellite, Concourse C and Main Terminal. In addition, the
modernized freight elevators will allow goods to be reliably delivered to the concession storage
areas, and safely and efficiently retrieved by concession tenants when needed. Reduced freight
and service use of passenger elevators in the North and South Satellite will also enhance
passenger travel experiences.

ALTERNATIVES CONSIDERED/RECOMMENDED ACTION: 
Alternative 1: The age and their obsolete technology require these elevators to be modernized to
current standards. This is the recommended alternative.
Alternative 2: The "Do Nothing" alternative results in continued customer service disruptions
and increased maintenance costs. Many parts are no longer available and have to be custom
manufactured, where possible. At some point in time, even custom fabricated replacement parts
will not be available, and the elevators will be modernized using maintenance funds, all at a
greater cost than proceeding with a designed and competitively bid modernization project.
