SUBJECT:  Parking Garage Emergency Lights project at Seattle-Tacoma International Airport 
(CIP #C800230) 
Amount of This Request: $1,157,081   Source of Funds: Airport Development Fund 
Est. State and Local Taxes: $0 
Est. Total Project Cost: $5,269,600 
ACTION REQUESTED: 
Request authorization for the Chief Executive Officer to prepare full design and construction bid
documents for the Parking Garage Emergency Lights project at Seattle-Tacoma International
Airport in the amount of $1,157,081, with a total estimated budget for the completed project of 
$5,269,600. 
SYNOPSIS: 
This request authorizes the Airport Parking Garage Emergency Lights project to move forward
with design and preparation of construction documents. This work will be performed under an
existing Emergency System Electrical Infrastructure Design indefinite delivery, indefinite
quantity (IDIQ) contract. This project was included in the 2012  2016 capital budget and plan
of finance. 
The parking garage has light fixtures throughout the parking areas and stairwells that allow for
24-hour operations. A small portion of those fixtures have dual functions and one is to serve as
emergency light fixtures when normal power is lost. The current emergency lighting system was
intended to be a temporary fix after a system failure in 2007. It is not fully code compliant. This
project provides the infrastructure that will ensure the Port continues to meet applicable life
safety code requirements for egress area illumination levels in the parking garage. In addition,
this project will eliminate the need for the battery-powered emergency lights currently in use, 
therefore eliminating the need to purchase batteries and pay associated disposal fees. During
design, staff will review available lighting fixtures and the selection will be based on fixtures that
will decrease electrical loads while providing acceptable light output. In addition, this design

will provide a foundation for a follow-up project to install new light fixtures throughout the
garage that will further reduce energy consumption. 
BACKGROUND: 
In 2007, the existing uninterruptible power supply (UPS) batteries that provided backup power
for egress lighting in the parking garage failed. In the event of a normal power failure, these
batteries would have provided backup power to the light fixtures on emergency circuits and these
fixtures maintained light levels necessary for safe egress from the garage. Following the battery
failures in 2007, temporary battery backup fixtures were installed to provide emergency egress
lighting until a permanent solution could be implemented. This temporary system is near the end
of its life and is not compliant with code requirements. The permanent solution will comply with 
egress lighting requirements as specified in NFPA 101: Life Safety Code (National Fire
Protection Agency). Failure of the UPS batteries and the corresponding costs to maintain the
temporary fixtures have compelled the Port to look at light fixtures and emergency power
distribution infrastructure alternatives that will utilize energy saving technology with acceptable
light quality while reducing maintenance and operating costs to provide reliable egress lighting. 
Staff has identified grants that may apply to this project, and will make a determination during
design to pursue them if applicable. In addition, staff may partner with the State of Washington
energy contracting office, and will make that determination during design if applicable. These
decisions would be detailed in future requests for authorization. If grants and state energy
partnership are deemed favorable to the project, then staff will return to Commission to request
design, scope, and any associated budget changes. 
PROJECT JUSTIFICATION: 
The purpose of this project is to provide the electrical infrastructure for a new source of
emergency power to feed the parking garage emergency lighting circuits in order to ensure that
code required level of egress illumination is provided for the safety of customers.
This project will provide the infrastructure for a follow-up project to replace the emergency light
fixtures in the parking garage. This new infrastructure capacity will provide the capability to
utilize energy saving lighting technology that will significantly decrease energy usage,
maintenance, and operating costs. 
Project Objectives: 
Satisfy applicable code requirements for emergency lighting; 
Provide proper egress lighting for the safety of customers; 
Allow for the capability to decrease electrical loads on the emergency circuits by
utilizing current lighting technology in fixtures that require less power; and 
Decrease maintenance and operations cost by utilizing current lighting technology in
fixtures with longer lamp life.

Budget Status and Source of Funds: 
The Parking Garage Emergency Lights project (CIP #C800230) is included in the 2012-2016 
capital budget and plan of finance as a business plan prospective project in the amount of
$750,000. The budget increase of $4,519,600 will be transferred from the Non-Aeronautical 
Renewal/Replacement (C800153), a business plan prospective project allowance, resulting in no
net change to the Aviation capital budget. The source of funds for this project is the Airport
Development Fund. 
The project budget has increased due to scope increase to include replacement of approximately
1,500 emergency light fixtures with more energy-efficient fixtures. This led to design concept
modifications to include four new electrical closets to comply with the National Electrical Code
that requires the segregation of normal and emergency power. Fire heat sensors were added to
comply with Port Fire Department requirements in each closet. The scope also increased to
include electric power revenue meters to provide monitoring of electric loads. The project
budget was also affected by a scope transfer to include emergency lighting replacement and
associated infrastructure on Floors 1 and 2 from the Parking Retrofit Project (CIP #C800225)
for design efficiency.

ENVIRONMENTAL SUSTAINABILITY: 
This project will provide the opportunity to apply environmental sustainability principles
primarily through the use of energy-efficient light fixtures by reducing the energy use by an
estimated 50% while providing more than four times the lamp operating life compared to what is
currently installed.
TRIPLE BOTTOM LINE SUMMARY: 
The project supports economic development by investing in an upgraded parking garage to serve
the public's safety needs at the Airport. Environmental sustainability principles will be
employed as needed or when practical. Procedures set forth in the Port's new Small Contractor
and Supplier Project from the Office of Social Responsibility will be used when applicable in the
project contracting process. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1  Do nothing. Do not implement any improvements to the existing parking garage.
This alternative is not recommended because the temporary battery backup emergency lighting
fixtures have reached their life expectancy and will begin to fail and the parking garage currently
does not meet egress lighting code. This alternative will negatively affect the safety of the
public. This is not the recommended alternative. 
Alternative 2  Provide new emergency power to allow for the emergency light fixtures to be
replaced with newer and more energy-efficient lighting technology. This alternative will meet
the life/safety code requirements for egress illumination levels and provide safety for the public.
This is the recommended alternative.
