Item No.
6a
Date of Meeting
April 28, 2009
DATE: April 1, 2009
TO: Tay Yoshitani, Chief Executive Officer
FROM: Richard Ottele, General Manager, Aviation Facilities and Infrastructure
Robert F. Riley, Director, Aviation Capital Improvement Program
SUBJECT: Fire Piping Upgrades at the Main Terminal of Seattle-Tacoma International
Airport.
ACTION REQUESTED
Request Port Commission authorization for the Chief Executive Officer to advertise for
construction bids, award the contract and construct the Fire Piping Upgrades Main Terminal
Project at Seattle-Tacoma International Airport (Airport), for an additional amount of $1,288,500
and a total project cost of $1,450,000.
SYNOPSIS
This memorandum requests authorization for construction and the approval to advertise for
construction bids for the Fire Piping Upgrades, Main Terminal Project. This project will replace
certain vulnerable portions of the Main Terminal fire main piping system to restore system
reliability and provide full monitoring compatibility with the central fire alarm system. The
Commission previously authorized $161,500 to complete design on September 23, 2008. This
authorization for construction will increase the project authorization by $1,288,500 for an
estimated total project cost of $1,450,000.
BACKGROUND
The existing fire sprinkler system main supply piping and valves were installed in the late 1960’s
as part of the Main Terminal construction. Several Main Terminal fire piping mains have
experienced pipe and joint failures over the past few years necessitating emergency repairs. The
subject fire piping has reached the end of its useful life and requires the proposed upgrades to
maximize system reliability. The grade of the current pipes does not meet current standards and
seismic bracing needs to be upgraded. In addition, the system has limited alarm-reporting
capabilities, adversely affecting the Port’s ability to monitor system readiness.

The Commission authorized $161,500 on September 23, 2008 to complete design of the fire
main piping and valves as well as enhancement of the fire alarm monitoring and reporting
system. The total estimated project cost at that time was $1,500,000. The project design is now
complete. The Commission is being requested to approve the advertisement for construction
bids and to authorize funding for construction at a new estimated total project amount of
$1,450,000.
PROJECT DESCRIPTION/SCOPE OF WORK
Project Statement:
Replace certain vulnerable portions of the Main Terminal fire main piping system to restore
system reliability and provide full monitoring compatibility with the central fire alarm system.
Project Objectives:
Enhance the reliability of the fire protection system for the Main Terminal.
Scope of Work:
Replace approximately 600 feet of fire main piping in the Main Terminal utility corridors with
new, thicker grade piping including installation of piping supports and bracing that meets current
seismic codes. The project will also replace the check valves and certain fire alarm valves prior
to each fire main branch serving the various zones in the Main Terminal. Further, new flow
switches will be installed and connected to the central fire alarm system to provide activation
signals for the Main Terminal fire sprinkler system. The scope of work for the replacement of
the gate valves isolating the domestic water main from the fire main piping will be transferred to
a future project to better facilitate shutdown impacts to the Main Terminal.
This requested action authorizes construction and the approval to advertise for construction bids.
STRATEGIC OBJECTIVES
This project supports the Port strategy to “Ensure Airport and Seaport Vitality” through
enhancing safety by ensuring the fire piping system will perform reliability.

ECONOMIC IMPACTS
This project will eliminate the need for emergency repairs of the approximately 40 year old Main
Terminal fire main piping system and improve fire protection in the Main Terminal.
ENVIRONMENTAL SUSTAINABILITY/COMMUNITY BENEFITS
No impact to the environment is anticipated as a result of this project. Upgrades will be
constructed with materials that have demonstrated long life and durability.
TRIPLE BOTTOM LINE SUMMARY
This project will improve the reliability of the Main Terminal fire piping system, have no impact
on the environment, and enhance safety for the community and traveling public at the Airport.
