SUBJECT:  Interim Westside Fire Station  Budget Request (CIP #C800876) 
Amount of this request:                 $609,000 
Total estimated project cost:          $9,788,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to increase funding for the Interim
Westside Fire Station project, at Seattle-Tacoma International Airport, by $609,000 for a new
total project total authorization in the amount of $9,788,000. 
EXECUTIVE SUMMARY 
This request is for additional budget for the Interim Westside Fire Station. The construction
schedule of the Fire Station has slipped primarily due to the impacts of COVID-19 and differing
site conditions found during excavation. As a result of this schedule slippage, additional costs are
forecasting beyond the project budget. The project team has forecasted $409,000, of the
$609,000 requested, will be required to complete the project. A further $200,000 is requested as
contingency for any unexpected future costs. 
This facility, once thought to have a limited use due to pending development, has been sited
where it can remain either as a fire station or other use. 
JUSTIFICATION 
Two factors have contributed to the project's cost growth: First, this project was placed on hold
through a mutually agreed to, no cost partial suspension of all on-site construction work with the
Contractor and the Port of Seattle in response to COVID 19. This moved the Substantial
Completion date by 63 days. 
The second factor was the impact of differing site conditions. Numerous obstacles were
uncovered during site and utility excavations. The project was able to cover the direct costs
related to the underground obstacles with existing contingency, but unable to cover the full cost

of the delay it caused. The impact of the delay to the project schedule is now resulting in the
need for additional budget to cover the increased Port staffing resources for this delay. 
This suspension along with the impact of the differing site conditions has moved construction
into an unfavorable weather window. The Port will continue to emphasize worker safety by
requiring the contractor to continue to follow COVID 19 protocols. Substantial completion date
is forecast to be May 31, 2021. 
Most of the project's cost growth has been driven by the need to cover staff's additional time. In
order to provide construction inspectors, resident engineers, construction managers, project
managers, engineering specialty consultants, security personnel, operational personnel, to
manage work around an active airfield, monitor and review contractor submittals, perform
quality checks, and manage the program, it is necessary to increase the budget to cover these
additional soft costs. 
The project team is evaluating the project schedule to determine responsibility for each delay.
Delays attributable to the contractor will remain the responsibility of the contractor to remedy. 
Diversity in Contracting 
The project team worked with the Diversity in Contracting Department to set goals for the Interim
Westside Fire Station. To-date, the WMBE utilization for this design-build contract is achieving
39.22%, above the original WMBE aspirational goal of 11%.
DETAILS 
This project will establish a stand-alone, fully functional fire station on the west side of the airfield
to meet Federal Aviation Administration (FAA) mandated airfield firefighting requirements. This
new fire station will provide necessary accommodations to house firefighters and Aircraft Rescue
Fire Fighting (ARFF) vehicles for 24/7/365 operation. This new facility will replace temporary
facilities that included a tent structure to cover one rescue vehicle and multiple leased rooms
within a nearby hangar that house firefighter quarters in a 'makeshift' or 'make-do' manner.
Planning for the future permanent fire station will not require the removal of this facility. 
Scope of Work 
The project scope of work has not changed. This project designs and constructs a building to
accommodate the necessary living quarters for five (5) firefighters and vehicle bays for the
storage of two (2) ARFF vehicles. The building is located directly east of the PACCAR hangar. 
The living quarters will consist of five (5) bunkrooms, a dayroom, kitchen, 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 vehicle bays
include features currently used at the existing fire station such as vehicle exhaust extraction.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
The project team has evaluated alternatives such as reducing the project scope and determined
that they are not viable solutions. 
Alternative 1  Increase the project budget by the forecasted $409,000 only, excluding the
$200,000 contingency. 
Cost Implications: $409,000 
Pros: 
(1) This will provide funding to cover known and anticipated costs. 
Cons: 
(1)  This budget amount would not provide contingency to cover unforeseen conditions. 
This is not the recommended alternative. 
Alternative 2  Include the $200,000 additional contingency to the project budget for a total
budget addition of $609,000. 
Cost Implications:  $609,000. Note:   Unspent contingency will be returned after project
completion for use in funding other Aviation projects. 
Pros: 
(1)     This will provide additional contingency of $200,000 in the event unforeseen
conditions arise. 
Cons: 
(1)   This is the highest cost alternative. 
This is the recommended alternative.
