SUBJECT: Renewal and Replacement of 42 Escalators and 2 New Escalators project at
Seattle-Tacoma International Airport (CIP # C800237).
Amount of This Request: $-0-           Source of Funds: Airport Development Fund
& Future Bonds
ACTION REQUESTED: 
Request Port Commission authorization for the Chief Executive Officer (CEO) to issue a request
for proposals for the Renewal/Replacement of forty-two (42) Escalators and 2 New Escalators
project (CIP # C800237) at Seattle-Tacoma International Airport (Airport).
SYNOPSIS: 
This memorandum requests approval to issue a request for proposals using the design-build
contracting method, in accordance with RCW 30.10.280 and 300  330, to replace 42 existing
escalators in the Main Terminal, Concourse B, and the South Satellite, and install two new
escalators in the South Satellite. The Commission previously authorized on April 13, 2010 the
advertisement of a request for qualifications under the design-build contracting procedure and to
apply a Project Labor Agreement. On July 22, 2008, the Commission authorized $3,183,000 for
design. An additional request for authorization is required for award of the contract. If the
Commission votes to authorize the award request, the total budget would equal $55 million.
BACKGROUND: 
The escalators included in this project have been in daily use since their installation in the early
1970's and have reached the end of their useful service life. Several of the escalators have failed
over the past few years causing passenger disruptions and requiring costly emergency repairs. In
an effort to lessen the impact of further failures, a significantly higher level of repairs and
maintenance has also been necessary, resulting in continuing impacts on the traveling public and
increased maintenance expenses.

This project will be executed using the "Design-Build" contracting method in accordance with
RCW 39.10.280 and 300-330. The project was approved by the legislatively-mandated Capital
Projects Advisory Review Board, Project Review Committee on February 2, 2010, to use the
Design-Build method. This contracting method promotes competition and innovation necessary
to address the complex construction methodologies and scheduling issues in this project, in order
to minimize disruptions to the traveling public and airport operations while maximizing schedule
performance. This approach allows the Port to evaluate and select the design-builder based on
technical qualifications/approach and price, using a specifically defined set of evaluation criteria.
The award will be based upon the highest scored proposal but not necessarily the lowest price, as
determined by the Port.
Under the design-build method, the Port will publicly advertise a Request for Qualifications
(RFQ). Following the RFQ process, the Port will issue a Request for Proposal (RFP). No more
than five respondents will be selected to submit a RFP. The proposers will prepare and submit
their proposed technical approach, escalator product, and price. The successful proposer will
perform the design, manufacturing and installation in accordance with the RFP requirements. As
required by RCW 39.10.330, honorarium payments will be provided to all selected finalists
submitting best and final proposals that are not awarded the contract.
As provided by Resolution No. 3605, after the best proposal is selected, Commission
authorization will be requested for the final design and construction funding, and award of the
design-build contract.
PROJECT DESCRIPTION/SCOPE OF WORK: 
Project Statement:
This project will replace 42 existing escalators that have reached the end of their useful life, and
include the installation of 2 new escalators at the South Satellite by December 2013 for
$55,000,000. The design life of the new escalators is 25  30 years.
Project Objectives:
Remove and replace the 42 existing escalators in an accelerated manner with the least
amount of disruption to Airport operations as possible.
Install 2 new escalators in the South Satellite to improve operational performance and
reliability, and address future passenger growth.
Include heavy-duty escalator components for improved reliability and overall longevity.
Increase the energy efficiency of the escalators.
Scope of Work:
Remove and replace 42 existing escalators at the Airport with new heavy-duty escalators in the
same locations and configurations, and add 2 new escalators at the South Satellite. The new
escalators in the South Satellite will be installed adjacent to the existing escalators traveling from

the transit station level, up to the mezzanine level, and continuing up to the concourse level. The
escalators will meet all current escalator code requirements.
STRATEGIC OBJECTIVES: 
Ensure Airport and Seaport Vitality
The project provides enhanced reliability and performance for critical vertical transportation in
significant areas of the Airport, which facilitates use of the Airport by the traveling public.
Exhibit Environmental Stewardship through Our Actions
This project is consistent with the Port's goal of improving the long term sustainability of its
facilities and operations. This project supports and encourages Airport environmental initiatives.
This project has a generally positive effect on the environment to the extent that the new
escalators will have more efficient drive motors and features that adjust the power demand and
speed of the escalators based on load and usage.

Given the nature of the design-build process being used for the escalator project, the accelerated
schedule, and the difficulty of integrating artwork into the specification criteria for the escalator
units, the Port will establish a separate work project for the art. The Art Oversight Committee
will be defining an art plan for this project.

ALTERNATIVES CONSIDERED/RECOMMENDED ACTION:
Alternative 1: Proceed with the Renew/Replace 42 Escalators and 2 New Escalators project
using the "Design-Build" contracting method. This approach renews and upgrades the aging
escalators at the Airport, improving passenger flow through the reduction of service outages.
This contracting method provides the opportunity for competitive delivery schedules and design
solutions, and effective pricing by proposers. This method will shorten the overall schedule and
decrease the risk associated with the traditional design-bid-build approach. This is the
recommended alternative. 
Alternative 2: Continue the repair and maintenance of the existing escalators. This is a reactive
approach that disrupts passenger flows throughout the facility and is not cost effective. This is
not the recommended alternative.
Alternative 3: Proceed with the Renew/Replace 42 Escalators and 2 New Escalators project
using the "Design-Bid-Build" contracting method. This approach renews and upgrades the aging
escalators at the Airport; however, the traditional Design-Bid-Build contracting method does not
adequately allow for innovation and competition by prospective manufacturers and/or general
contractor. This method would base the selection on price only versus best overall approach that
considers technical approach and price, lengthen the overall schedule, and put the Port at greater
risk for design changes, schedule delays, and change orders. This is not the recommended
alternative.
PREVIOUS COMMISSION ACTION: 
On April 13, 2010, the Commission authorized the advertisement of the Request for
Qualifications under the Design-Build contracting procedure, and the application of a Project

Labor Agreement. The project scope was changed to include a second new escalator in the
South Satellite.
On September 22, 2009, the Commission was briefed on the Airport's "Facility Functionality
and Readiness", which included a discussion of the escalators and elevators.
On July 22, 2008, the Commission authorized $3,183,000 to prepare the performance
specifications and preliminary design for the Renew/Replace 42 Escalators and 1 New Escalator
project at Seattle-Tacoma International Airport.
