DATE:     May 12, 2023 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Laurel Dunphy, Director, Airport Operations 
Eileen Francisco, Director, Aviation Project Management Group 
SUBJECT:  3rd Floor Ground Transportation Booth Enhancements (CIP #C801128) 
Amount of this request:               $2,941,000 
Total estimated project cost:          $3,181,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to take all steps necessary to
complete the 3rd Floor Ground Transportation Booth Enhancements project at Seattle-Tacoma
International Airport (SEA). This request is in the amount of $2,941,000 for a total authorization
amount of $3,181,000. 
EXECUTIVE SUMMARY 
This project will renovate and expand the existing ground transportation booth (the GT booth)
located on the 3rd Floor of the Main Garage at SEA. The GT booth functions as an administrative
center for the orderly permitting and control of all commercial ground transportation activity at
SEA. As a place of work, the GT booth  accommodates sixteen  Port of Seattle ground
transportation controllers on a 3-shift schedule. The existing facility was constructed over twenty
years ago when SEA activity levels were much lower and is now a confined and inefficient space.
Currently, the booth does not include a break room or restroom for staff. The new GT booth will
provide an inviting environment for customers and the existing customer restrooms will also be
upgraded to meet accessibility requirements. These improvements support SEAs customer
service goals. 
JUSTIFICATION 
This project reinvests in facilities essential to ground transportation operations at SEA supporting
the Century Agenda Goal to advance this region as a leading tourism destination and business
gateway by meeting the region’s air transportation needs by delivering vital facilities and
infrastructure in a sustainable and cost-effective manner.

Meeting Date: May 23, 2023 
The design of this project will utilize an existing indefinite delivery indefinite quantity (IDIQ)
contract that has a Women and Minority-Owned Business Enterprise (WMBE) commitment of
fifteen percent. The project team will work with the Diversity in Contracting department to
establish additional WMBE aspirational goals within the construction phase of this effort. 
DETAILS 
The existing GT booth was constructed in 2001 and is located on the 3rd Floor of the Main Garage
as part of the Ground Transportation Center servicing courtesy vehicles, taxis, pre-arranged limos
and transportation network companies like Uber and Lyft. Port staff (GT controllers) currently
work within this facility supporting the administration and management of ground transportation
permits and providing customer service to SEA passengers. The initial construction did not
include a few basic amenities for staff (e.g., break area, lockers), and with the growth in SEA
activity the facility is now very confined and has an inefficient layout for current operational
needs. The existing HVAC system is inefficient impacting workspace conditions and needs to be
upgraded. The existing facility is approximately 1,000 square feet in size, and the new expanded
facility will be approximately 1,700 square feet. Once completed the new facility will maximize
staff  productivity,  and  provide  a  high  level  of  service  to  SEA  passengers  and  ground
transportation providers. 
The project costs have increased since the project was originally planned. The cost increases are
associated with the HVAC system risk given the limited vertical clearance in the Main Garage.
Two potential solutions were identified that will be evaluated during design. Additional project
contingency and design costs were included to manage this risk. 
The project will be phased during construction to maintain SEA operations.  A portion of the
facility will be constructed first, then Port staff will be relocated into the new facility, prior to the
demolition of the existing facility. The two existing customer restrooms will also be maintained
until the new restrooms are completed. 
Scope of Work 
The scope of this project includes: 
(1)   Expansion of administration space to support up to eight staff per shift. 
(2)   Addition of a staff breakroom and restroom. 
(3)   Upgrade of customer restroom facilities meeting accessibility requirements. 
(4)   Upgrade and expansion of existing infrastructure systems, including HVAC, to support
functions. 
(5)   Technology enhancements include improved cell phone coverage and Wi-Fi.

Pros: 
(1)   No further investment required by the Port. 
Cons: 
(1)   Staff support space would remain confined and inefficient. 
(2)   Does not provide technology enhancements. 
(3)   Does not upgrade customer restrooms to meet accessibility requirements. 
(4)   Poor HVAC performance continues to negatively affect workplace conditions.
