MEMORANDUM 
COMMISSION AGENDA             Item No.      6a 
Date of Meeting    February 1, 2011 

DATE:    January 21, 2011 
TO:     Tay Yoshitani, Chief Executive Officer 
FROM:    Wayne Grotheer, Director, Aviation Project Management Group 
David Soike, Director, Aviation Facilities and Capital Program 
SUBJECT:  Renewal and Replacement of 42 Escalators and 2 New Escalators project at
Seattle-Tacoma International Airport (CIP#C800237). 
Amount of This Request: $51,817,000       Source of Funds: Airport Development 
Fund and existing Revenue Bond Proceeds 
Total Project Budget: $55,000,000         Job Created: 80 
Sales Tax Paid: $3,819,000 
ACTION REQUESTED: 
Request Port Commission authorization for the Chief Executive Officer to execute a contract
with the selected Design-Build team and construct the Renewal/Replacement of forty-two (42)
Escalators and 2 New Escalators project (CIP # C800237) at Seattle-Tacoma International
Airport (Airport). The amount of this request is $51,817,000. The total cost of the project is
estimated to be $55,000,000. 
SYNOPSIS: 
This memorandum requests approval to execute a contract and proceed with the replacement of
forty-two (42) existing escalators in the Main Terminal, Concourse B, and the South Satellite,
and installation of two new escalators in the South Satellite. These existing escalators are critical
infrastructure essential to the operation of Seattle-Tacoma International Airport and have reached
the end of their useful service life.
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 been necessary, resulting in increased maintenance expenses.

The Commission previously authorized the use of the "Design-Build" contracting method in
accordance with RCW 39.10.280 and 300-330. The project was approved by the legislativelymandated
Capital Projects Advisory Review Board, Project Review Committee on February 2,
2010. 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 is based upon the highest scored proposal as determined by the Port. 
The Port publicly advertised an RFQ on May 21, 2010. Four of the six firms responding to the
RFQ were deemed qualified to submit an RFP. The Port issued the RFP on July 16, 2010 and
proposals were received on September 9, 2010. Interviews were conducted on October 16 and
17, 2010. The Port received four best and final offers on December 10, 2010. The technical
scores for the four finalists were tightly grouped, with a total variance of just 6.5% from highest
to lowest. The successful firm, Turner Construction Company, had both the highest technical
score and the lowest price. 
The successful firm will perform the final design, manufacturing and installation in accordance
with the RFP requirements. As required by RCW 39.10.330, honorarium payments will be
provided to the three finalists submitting best and final proposals that are not awarded the
contract. The honorarium amount is $25,000. 
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. The new escalators will
meet all current escalator code requirements. The airlines have approved this project. 
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. 
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 and executing an art plan for this project. 
Source of Funds 
This project (CIP # C800237) was included in the 2011-15 capital budget and plan of finance as
a committed project with a budget of $55.0 million. The funding source will be the Airport
Development Fund and existing revenue bonds.

which point approximately $.21 will have been
added to CPE; however, this project was already
included in the business plan forecast so there is no
change. 
ECONOMIC IMPACTS: 
The Airport will provide a higher level of service to the traveling public, while reducing
escalator repair costs an estimated $250,000 annually. 
ENVIRONMENTAL SUSTAINABILITY/COMMUNITY BENEFITS: 
The new escalators will be 20% more energy efficient than the existing escalators. 
TRIPLE BOTTOM LINE SUMMARY: 
This project will reduce the overall maintenance costs by reducing the high costs of emergency
repairs. This effort reduces the Airport's exposure to liability by replacing the escalators that are
beyond their useful life. Ensuring that the Airport's vertical transportation system is safe and
reliable promotes efficient Airport operations that benefit the traveling public, while improved
energy efficiency benefits the environment. 
PROJECT SCHEDULE: 
Request for Commission Authorization to Award       February 2011 
Notice to Proceed for final design and construction      March 2011 
Installation Complete                       September 2013 
ALTERNATIVES CONSIDERED/RECOMMENDED ACTION: 
Alternative 1: Proceed with the execution of a "Design-Build" contract with Turner
Construction Company, authorizing the contractor to complete the design and construct the
project. This approach renews and upgrades the aging escalators at the Airport, improving
passenger flow through the reduction of service outages. This is the recommended alternative. 
Alternative 2: Cancel the procurement. Pay the honorarium to all four proposers and 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.
