SUBJECT:  Interim Fire Station  West Side (CIP #C800876) 
Amount of this request:               $5,295,000 
Total estimated project cost:          $5,500,000 
ACTION REQUESTED 
Request Commission Authorization for the Executive Director to: (1) execute an amendment to
the lease with PACCAR to remove  land from their pad needed to meet Port Fire Department
requirements, and (2) authorize the design and construction of an interim fire station next to
the PACCAR hangar on the west side of Sea-Tac International Airport. The total estimated
project cost is $5,500,000. 
EXECUTIVE SUMMARY 
This project would establish a stand-alone, fully functional fire station next to the PACCAR
hangar, which will provide adequate accommodations for Fire Department staff and equipment
enabling the Fire Department to meet the Federal Aviation Administration's (FAA's) mandated
airfield response time. 
Since 1979, the Airport Fire Department has operated out of a single fire station, located
adjacent to the main terminal building on the east side of the airport runways. As part of the
FAA Federal Aviation Regulation Part 139 airport certification process, the Fire Department is
required to demonstrate its ability to respond to the midpoint of the furthest runway within
three (3) minutes. The completion of the airport's third runway and reconfiguration of taxiways
impacted this response time such that additional location has been arranged in order to correct
the situation. 
In order to meet the FAA's mandated response time the Fire Department has been operating
from a small converted conference room within the PACCAR hangar, located on the west side
of the airfield. This temporary facility is inadequate for continuing Fire Department operations.

COMMISSION AGENDA  Action Item No. __8b__                              Page 2 of 5 
Meeting Date: February 27, 2018 
An option to enlarge and segregate this facility within the PACCAR hangar could not meet the
Fire Department's requirements and PACCAR's operations. 
In negotiations with PACCAR, a longer-term solution was agreed upon that will meet the needs
of the Fire Department while minimizing the impact on flight operations at PACCAR. 
As discussed in the alternatives section of this memorandum, by building this interim facility
detached from the PACCAR facility the anticipated new Westside Fire Station can be built at this
site without disrupting the Fire Department's functions on the Westside of the airfield. Port
staff anticipates that this interim facility will be utilized at this Westside location until at least
the 4th quarter of 2023, for a minimum estimated life of four years. 
JUSTIFICATION 
The current temporary housing at PACCAR is extremely small and does not meet the Fire
Department's personnel accommodation standards. In this small space, the Fire Department
can only operate a skeleton crew of two (2) fire fighters. To properly staff the station, the Fire
Department requires a total of five (5) fire fighters and two (2) Aircraft Rescue Fire Fighting
(ARFF) trucks at the location. 
DETAILS 
Scope of Work 
This project involves installing a modular type building to accommodate the necessary living
quarters for the five (5) firefighters and a steel framed metal covered shelter for the storage of
two (2) ARFF trucks. These buildings will be located directly east of the PACCAR hangar within
their current lease boundary. Additional asphalt placement, a concrete slab, security fence
relocating and utility work is required to facilitate placement of the new modular building and
shelter. The living quarters will consist of five (5) bunkrooms, a day room, kitchen, male and
female restrooms with showers, laundry facilities and an exercise room. Secured entry doors,
video conferencing equipment and an emergency response alerting system will be installed.
The ARFF truck storage shelter will include features currently used at the existing fire station.
Design will be completed using a combination of in-house and contracted services.  Also
included in the project is procurement of an estimated $60,000 of furnishings for the station. 
The Port's Aviation Project Management Group is coordinating and partnering with the Port's 
small business group to help identify and outreach to small businesses for opportunities within
the project scope of work and will be establishing contracting goals for the project.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
All alternatives contemplate the construction of a permanent fire station on the west side of
the airport, at the site of the PACCAR Hangar. This project, in the $35 to $45 million range
would start construction after the expiration of the hangar lease, and be completed in
approximately 2023. 
Alternative 1  Status Quo - Do not perform the improvements or provide a secondary ARFF
truck shelter. 
Cost Implications: $0 
Pros: 
(1)   Lowest capital cost and no long-term lease payments. 
Cons: 
(1)   The Fire Department would continue to use inadequate facilities on the west side. 
(2)   The current agreement can be terminated by PACCAR on very short-term notice. 
(3)   PACCAR has requested that the Port's use of its space be separated and segregated
from its operations. 
This is not the recommended alternative. 
Alternative 2    Enter into a long term agreement with PACCAR and construct the Fire
Department's west side facility as a segregated space within the PACCAR hangar. 
Cost Implications: $2,600,000 
Pros: 
(1)    This alternative responds to PACCAR's request that a segregated space be created. 
(2)    The Fire Department would have the storage space for two (2) ARFF trucks. 
Cons: 
(1)    This alternative would not meet the requirements by the Fire Department to facilitate
five (5) firefighters due to the limited amount of space that PACCAR is willing to
provide inside the building for the tenant improvements. 
(2)    The Port will incur a build out expense in addition to a long-term lease agreement. 
(3)    Utility payment responsibilities would be complicated to resolve. 
(4)    Space build out inside of PACCAR hangar presumably would have to move again if a
new primary station was built on the PACCAR site as depicted in our SAMP plans.

COMMISSION AGENDA  Action Item No. __8b__                              Page 4 of 5 
Meeting Date: February 27, 2018 
This is not the recommended alternative. 
Alternative 3  Build a separate modular building providing firefighters an improved living
space and a shelter for two (2) ARFF vehicles. 
Cost Implications: $5,500,000 
Pros: 
(1)   The Fire Department would have a facility to meet the FAA's response time
requirements. 
(2)    The facility would be improved and meet adequate accommodations for the Fire
Department. 
(3)    This alternative responds to PACCAR's request that a segregated space is created. 
(4)    The modular building offers flexibility to respond to future needs. 
(5)   The Fire Department would have the storage space for two (2) ARFF trucks. 
(6)   Building detached from the PACCAR facility allows the anticipated new Primary Fire
Station to be built without disrupting Fire Department operations on the Westside of
the airfield. 
Cons: 
(1)   Constructing a separate building outside of the PACCAR hangar will cost more. 
(2)   Additional paving would be required. 
This is the recommended alternative.

Annual Budget Status and Source of Funds 
This project was included in the 2018  2022 capital budget and plan of finance with a budget
of $2,400,000 million. The cost increase was due to building a separate modular building
providing firefighters an improved living space and a shelter for two (2) ARFF vehicles. The
budget increase will be transferred from the Aeronautical Allowance CIP (C800753) resulting in
