SUBJECT:  Fire Station Electrical Service Upgrade (CIP #C800479) 

Amount of This Request:    $346,000    Source of Funds:   Airport Development Fund 
Est. State and Local Taxes:  $122,000    Est. Jobs Created: 24 
Est. Total Project Cost:    $2,033,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to proceed with design of the
Sea-Tac Airport Fire Station Electrical Service Upgrade project and use Port crews to support
site investigation needed to develop the construction contract documents in the amount of
$346,000 for a total estimated project cost of $2,033,000. 
SYNOPSIS: 
This project upgrades aging electrical infrastructure. Commission authorization is requested to
proceed with design of the Fire Station Electrical Service Upgrade project. The existing system
is over 40 years old and at capacity. In order to maintain a relia ble and adequate source of power
for current as well as future needs, the power service to the station must be renewed and
replaced. This project would install a new service, switchgear, and an emergency generator.
Staff intends to combine design and construction of this project with the Feeder 101 Tap
Replacement Upgrade project for cost efficiency. 
Design services will be performed using an existing mechanical electrical indefinite delivery,
indefinite quantity service agreement that was competitively procured. 
This project was included in the approved 2013-2017 capital budget and plan of finance. 
BACKGROUND: 
The source of electrical power to the Fire Station is provided through a 300 kilovolt amps (kVA) 
120/208 volt (V) transformer and switchgear. The existing equipment is a decade beyond its
predicted life, is loaded to its capacity, and therefore has caused circuit breaker outages at the
Fire Department.

COMMISSION AGENDA

The existing 120/208V transformer and switchgear will be replaced with equipment with an
increased capacity and a new generator will be added. The new generator will serve the entire
facility enabling the Fire Station to be fully operational during an emergency and will allow for
the addition of future loads. 
This project will also add 480V power to meet current and future electrical upgrades as well as
provide for a future Fire Station Heating, Ventilation, Air Conditioning (HVAC) project to
address HVAC deficiencies. This project will be combined with the nearby Feeder 101 Taps
Replacement project into one construction contract. Both projects have similar medium voltage
equipment requirements and are tied to Feeder 101, which is adjacent to Air Cargo Road,
adjacent to the Fire Station. Combining the project s takes advantage of potential cost
efficiencies. The Feeder 101 Taps Replacement project was previously authorized for design by
Commission on January 22, 2013. 
PROJECT JUSTIFICATION: 
This request will authorize design services to replace the 300 kVA, 208/120V transformer and
switchgear that provides power to the Fire Station. As stated above, the equipment is over 40
years old, fully loaded, and well past the predicted life of 30 years. A lso, the Fire Station has
had power failures due to overloading. New 480V service will be added to support future
HVAC improvements planned for the Fire Station. 
Project Objectives: 
Replace the existing limited capacity, unreliable power source with a new, codecompliant
power source capable of meeting current and projected demand. 
Add a 480V transformer, associated switchgear, and an emergency generator to meet
future needs and provide backup power to support continuous operations.

Lifecycle Cost and Savings: 
The project replaces existing electrical infrastructure with a higher capacity. T he potential for
higher electrical use is included to meet long-term Fire Department needs. Maintenance trouble
calls will decrease. Estimated operating costs will be verified during the design stage. 
STRATEGIC OBJECTIVES: 
This project will support the Century Agenda objective of meeting the region's air transportation
needs at Sea-Tac Airport for the next 25 years. In order to support existing operations, and
further growth, the Airport must maintain critical assets such as the Fire Station.

ENVIRONMENTAL SUSTAINABILITY: 
This project demonstrates environmental sustainability by improving existing Port assets and
better utilizing existing resources. This project will replace existing equipment with new, more
efficient systems. Existing materials will be recycled. 
BUSINESS PLAN OBJECTIVES: 
This project will support the Airport Strategy of ensuring a safe and secure airport by improving
aging and inefficient physical assets. 
TRIPLE BOTTOM LINE SUMMARY: 
This project provides a cost-effective means of accomplishing necessary renovation of the Fire
Station electrical power source. Without reliable electrical power, the Fire Station cannot
operate to fully benefit our business customers, travelers, and the region. An effective Fire
Station benefits both the Airport and surrounding communities. 
This project provides the potential for small business participation on the subcontractor level
particularly for the sitework trades. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1  Do nothing. The aging equipment would be replaced when there are failures.
This option will increase the costs to the Port for emergency replacement and there is a high
possibility that the Fire Station would be out of commission for an extended period of time. This
option is not considered viable. This is not the recommended alternative. 
Alternative 2  Replace the existing 120/208V equipment in-kind. This option addresses the
aging equipment; however, it does not address the current overloaded equipment or any future
needs requiring a 480V service. This is not the recommended alternative. 
Alternative 3  Replace the existing 120/208V equipment with a larger capacity system. This
option addresses the aging overloaded equipment; however, it does not address any future needs
requiring a 480V service. This is not the recommended alternative. 
Alternative 4  Replace the existing 120/208V equipment with a larger capacity system and add
a 480V service. This alternative addresses all of the electrical needs of the Fire Station for the
next 15 years. This is the recommended Alternative. 
OTHER DOCUMENTS ASSOCIATED WITH THIS REQUEST: 
None. 
PREVIOUS COMMISSION ACTIONS OR BRIEFINGS: 
On January 22, 2013, the Commission authorized funding for design of the Feeder 101
Taps Replacement project in the amount of $500,000.
