SUBJECT: Holdroom Seating for Concourse B and C (CIP #C800833)
Amount of this request:
$9,226,000
Total estimated project cost:
$9,300,000
ACTION REQUESTED
Request Commission authorization for the Chief Executive Officer to (1) procure and install
replacement seating for all holdrooms in Concourses B and C; (2) design and construct electrical
improvements to power 100% of the new seating that will allow passengers to charge their
electronic devices such as phones, computers, and other personal electronics; (3) Utilize Port
crews and small works contracts. The amount of this request is $9,226,000.
EXECUTIVE SUMMARY
This project replaces existing holdroom seating in Concourses B and C with new seating that will
improve customer comfort and will provide additional power access and supporting
infrastructure for charging personal electronic devices. The new seating will meet the recently
established standard with a modern, durable and attractive product that is expected to require
less maintenance than existing seating.
Existing holdroom seating on Concourses B and C is worn, is a mix of airline and airport-owned
seating, and is in need of replacement. In addition, existing electronic device charging outlets
are not sufficiently provided to meet customer demand and depending on location are
provided at only 25-35% of the holdroom seats.
Comfortable, modern and fully powered seating throughout the holdrooms at Concourses B
and C will enhance passenger experience and support the Century Agenda goal to make Sea-Tac
the West Coast “Gateway of Choice.”
JUSTIFICATION
The project will implement new seating to improve passenger experience in all Concourse B and
C holdrooms. The Port executed an airport-wide seating contract as a result of a competitive

procurement authorized by Commission in 2016. The new seating was selected based on best
value for total cost of ownership, comfort, aesthetics, maintainability, environmental benefits
and small business factors.
DETAILS
The seating bolts together in 4 to 5 seat benches that are stable, sturdy, and due to substantial
weight, are expected to remain in place. Based on the preferred layout, the project will install
benches perpendicular to the main walkway, with 2-seat airside benches at the ends of double
rows in some locations. Seating will be placed to maximize the number of seats in each
holdroom while also providing adequate circulation areas. ADA seating will be provided near
service counters at every gate. Floor receptacles will be provided to minimize cord runs from
seating and to keep these cords out of walkways for improved customer safety.
To distribute power for the new seating, the project will install new electrical panels on the
ramp level, with new circuit runs to all holdroom locations. Power bars for the seating are
raised and located between chairs, making access easy and convenient. Passengers will have
access to both 120V and USB outlets for charging personal devices such as cell phones and
laptops at the seating.
Scope of Work
The project will install new seating in all holdrooms throughout Concourse B and Concourse C in
layouts that optimize the number of seats and level of service in each holdroom. The project
will also install improvements necessary to provide power to all seating, to allow customer
access for 120V and USB device charging.
Schedule
The project will install the new seating by the end of 2017 including charging stations where
electrical power is currently available in the holdrooms. Electrical improvements required for
providing power at 100% of the seats will follow and will be performed through a major works
contract by the end of 2018.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Install Vitra seating at Concourse B and C holdrooms. Provide power access for
charging personal devices only where there is currently electrical access provided.
Cost Implications: $6 million
Pros:
(1) Implement new seating standard in two Airport concourses.
(2) Lowest cost alternative to install new seats.
(3) Slightly higher seating capacity than Alternatives 2 and 3.
Cons:
(1) This alternative only provides charging options for 20 – 30% of the seats and
availability varies by holdroom.
(2) Layout constrained by existing floor boxes to provide power access.
(3) Does not improve existing level of service for power access.
This is not the recommended alternative.
Alternative 2 – Install Vitra seating at Concourse B and C holdrooms. Provide power access to
75% seating.
Cost Implications: $8.2 million
Pros:
(1) Implement new seating standard in a key Airport area.
(2) Power access improved over Alternative 1.
(3) Slightly higher seating capacity than Alternative 3.
(4) Less cost than Alternative 3.
Cons:
(1) Fewer circuits will be provided to holdrooms than Alternative 3, resulting in zones
with no capacity for powered seating.
(2) Design options for holdroom seating are more limited than Alternative 3, due to non-
powered holdroom areas.
This is not the recommended alternative.
Alternative 3 – Install Vitra seating at Concourse B and C holdrooms. Provide power access to
100% seating.
Cost Implications: $9.3 million
Pros:
(1) Implement new seating standard in a key Airport area.
(2) Most flexible layout by providing power completely throughout the seating areas.
(3) Best level of customer service.
