PORT OF SEATTLE
MEMORANDUM
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.
