ACTION REQUESTED 
Request Commission authorization for  the Chief Executive Officer to authorize (1) the
preparation of design and construction documents  to update the Airport parking garage
emergency phone system, and (2) use of Port crews to construct the project. 
SYNOPSIS 
This project is a complete overhaul and modernization of the Airport parking garage emergency
phone system. The project will mitigate the risk of failure by obsolete phone equipment, and
correct the inability to determine the location of 911 requests for assistance in the parking
garage. 
BACKGROUND 
The Airport parking garage emergency call stations are essentially two systems operating in
parallel and encompasses both a 1970's era phone handset system, currently maintained by the
Port of Seattle Fire Department, and a 1990's era intercom system, currently maintained by
Aviation Maintenance.  Neither system has the ability to locate the caller to aid the 911
dispatcher. The 1970's era phone handsets are no longer manufactured, and replacement parts
for the system are difficult to find or are not available. The 1990's era intercoms are dependable
and are currently used throughout much of the Airport.
Today's emergency call stations, phone handsets and intercoms, are not consistently located 
throughout the parking garage. For example, there are intercoms in two of the stairwells on the
east side of the parking garage, one on each floor, but there are no intercoms in the other
stairwells.  The south elevator bank has an intercom on each floor, the other elevator banks do

not. Variation in locations depending on where you are in the parking garage can make
emergency call stations hard to find. 
PROJECT JUSTIFICATION AND DETAILS 
Key performance problems are the lack of consistency in the location of the emergency call
stations, two disparate systems are currently required and the inability to obtain parts for the
older system. These two systems must be monitored by different departments  911 Dispatch
and Fire Department. Finally, the current systems do not automatically locate the person needing
assistance. Therefore, the Fire Station and 911 Dispatcher cannot locate a caller automatically 
and must rely on the caller's ability to identify their location during an emergency.
An emergency phone system is not required by code; however, providing one is standard
industry practice. 
Project Objectives 
Improve public safety: 
Remove obsolete equipment 
Locate the new emergency call stations in consistent, central locations, to enable the
public to easily find them 
Enable the emergency call stations to indicate the location of the caller to 911 dispatch 
Scope of Work 
Design will be performed by an existing IDIQ consultant and the work will be performed by port
crews and small works contractors. In order to mitigate the risks associated with the current
emergency phone system this project includes the following components: 
Decommission the phone handset system 
Relocate intercoms from the garage stairwells and intercoms located in the southern
portion of the parking garage to central locations at elevator banks on each floor of the
parking garage and to the walkway leading to the Light Rail Station 
Connect each intercom with communications cabling to the existing 911 system 
Revise signage to help passengers locate the emergency call stations

Budget Status and Source of Funds 
This project was included in the 2015  2019 capital budget and plan of finance with a budget of
$440,000. Since that time, the cost estimate has been refined resulting in a capital cost reduction
and an operating cost increase for a net reduction of $4,000 in the total project cost. The funding
source will be the Airport Development Fund.

Lifecycle Cost and Savings 
The project removes obsolete equipment that was maintained by the Fire Department at minimal
cost. Removal of this equipment will not affect lifecycle costs and the Fire Department staff will
not be reduced as a result of this project. The project also relocates several intercoms to central
locations. The intercoms are proven hardware and  require  little maintenance. Airport 
Maintenance anticipates no impact to operation and maintenance (O&M) costs as a result of this
project.

STRATEGIES AND OBJECTIVES 
The project supports the Port's Century Agenda objective of meeting the region's air
transportation needs at Sea-Tac International Airport for the next 25 years by improving security
and customer service.  It also supports the Airport's strategic goal of operating a world-class
international airport by ensuring safe and secure operations through enhanced security. 
TRIPLE BOTTOM LINE 
Environmental Responsibility 
This project reuses existing intercoms.  The project will recycle wire to be removed when
possible. 
Community Benefits 
The project supports public safety. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1) Keep the status quo. This alternative would leave the emergency phone handsets
and intercoms call station in place.
Capital Cost: $0. 
Pros: 
The phone handset parts could be repaired or decommissioned as they fail. The existing
intercoms would remain in place. The Port could delay expenditure of the cost of system
design and replacement, using the funds for other purposes.
Cons: 
This alternative does not address lack of consistency in location of emergency call
stations throughout the parking garage and today's systems can't automatically provide 
the caller's location to 911 Dispatch. This alternative does improve reliability or public
safety. This is a no-cost alternative. 
Alternative 2) Remove the obsolete phone handset system. E xpand installation of the intercoms
to all elevator banks and to stairwells on the east side to the garage. Intercoms will be located at
each of the 5 elevator banks with one on each of the 8 floors for a total of 40 locations (8 are
currently located at the southernmost elevator bank) and they will be located at each of the 6
eastern stair wells with one on each floor for a total of 48. This involves removing all obsolete 
phone handsets, removing intercoms from the south section of the Airport parking garage,
relocating intercoms to the elevator banks and to the stair wells on the east side of the parking
garage (one per floor at each location), and relocating one intercom to the walkway leading to
the Light Rail Station.  The relocated intercoms would be connected to a more modern 
communication system connected to the Airport's computer network. This allows 911 Dispatch 
to automatically locate the person needing assistance.

Capital Cost: $900,000; Expense: $158,000. 
Pros: 
This alternative satisfies the need to remove the obsolete phone handsets, removes
intercoms from arbitrary locations in southern area of the parking garage and allows the
911 Dispatch to automatically locate the person needing assistance. Also, this alternative
adds intercoms to the eastern stairwells in locations that have no emergency call stations;
this will make finding an intercom along the eastern side of the parking garage easier. 
Cons: 
The phone handsets and intercoms will not be located between parking stalls. This will
require travelers or employees to use intercoms at elevator banks, stairwells or use their
cell phones.  The emergency call stations in the east stairwells are easier to find;
however, most travelers use the elevators for vertical circulation. Adding call stations to
the east stairwells is not cost effective. Adding locations in the stairwells adds over
$500,000 without appreciably increasing safety. 
Alternative 3) This alternative is similar to alternative 2 with the following exception: intercoms
will not be installed in stairwells on the east side of the parking garage. This alternative removes 
the obsolete phone handsets and expands the intercom locations to all elevator banks. Intercoms
will be relocated to each of the 5 elevator banks with one on each of the 8 floors for a total of 40
locations (8 are currently located at the southernmost elevator bank).  This involves removing
obsolete devices, removing intercoms from the south section of the Airport parking garage,
relocating intercoms to the elevator banks and relocating one intercom to the walkway leading to
the Light Rail Station.  The relocated intercoms would be connected to a more modern 
communication system connected to the Airport's computer network. This allows 911 Dispatch
to automatically locate the person needing assistance. 
Capital Costs: $378,000; Expense: $158,000 
Pros: 
This alternative satisfies the need to remove the obsolete phone handsets, removes
intercoms from arbitrary locations in the southern portion of the parking garage and 
eastern stairwells, and allows the 911 Dispatch to automatically locate the person needing
assistance. As stated in alternative 2, the emergency call stations in the east stairwells are
easier to find; however, most travelers use the elevators for vertical circulation. Adding
call stations to the east stairwells is not cost effective. This approach has lower cost than
alternative 2. 
Cons: 
The intercoms will not be located between parking stalls nor stairwells. This will require
travelers or employees to use intercoms at elevator banks or use their cell phones. 
This is the recommended option.
