SUBJECT:  Concourse A, B and C Carpet Replacement project at Seattle-Tacoma International

ACTION REQUESTED 
Request a single Commission authorization for the Chief Executive Officer to: 1) proceed with
design of carpet replacement on Concourses A, B and C; and 2) advertise and execute a
construction contract to install carpet on Concourses A, B and C; and 3) authorize the use of Port
Crews to assist in construction activities for the project. This single authorization is for 
$3,636,000 of a total estimated project cost of $3,661,000. 
SYNOPSIS 
The carpeting in the gate hold rooms in Concourses A, B and C has become so unsightly that our
airline customers have requested that it be replaced as soon as possible. This customer driven
urgency is the reason for the single authorization request for both design and construction. This 
project will remove the existing carpet on concourse A, B and C and replace it with a carpet tile
system. The existing roll carpet was installed in the concourses in 2004 and 2005. It is worn and
unsightly and in need of replacement. 
BACKGROUND 
Concourse A was constructed and opened to the public in 2004. Carpeting on Concourses B and
C was installed in 2005 to match that installed in Concourse A. The service life expectancy of
carpet is typically 5-7 years and the carpeting on these concourses has already exceeded this
expectancy. 
Replacing carpeting in the aircraft gate hold rooms with terrazzo was an alternative that was
evaluated but not determined to be the preferred alternative. Terrazzo is a hard surface material
that is very wear resistant and an excellent choice for high traffic areas of the airport, like

concourse circulation corridors. However it is not suitable for all locations. Not only is terrazzo a
more expensive material to install (roughly five times more expensive than carpet alternatives), it
requires a longer and more invasive installation method, with each location barricaded and
separately ventilated. Further, as  a hard material, it can introduce acoustic reflectivity problems
creating a very noisy environment that would negatively impact customer experience. 
PROJECT JUSTIFICATION AND DETAILS 
The current rolled carpet was installed on Concourse A in 2004; the carpet on Concourses B and
C was installed in 2005. The aging carpet is worn and badly stained in many areas. Our airline
customers have requested that we replace all the carpet in hold room areas as soon as possible.
Replacing the carpet with carpet tile will greatly improve the aesthetics of the concourses while
providing a better option for replacing stained or damaged areas of carpet in the future as the
individual tiles can be quickly replaced if needed. 
Project Objectives 
Improve the declining tenant and customer satisfaction and feedback related to the look and feel,
of the departure experience in the hold rooms of Concourses A, B and C. 
Scope of Work 
The project will remove and replace carpeting on Concourses A, B and C and repair any
adjoining terrazzo areas that may be damaged during installation. The project will also remove
two payphone banks on Concourse A while preserving the floor power currently servicing these
units to provide power, to future hold room seating that will to be installed later under a separate
future project.

Budget Status and Source of Funds 
This project, CIP #C8007666 was included in the 2016-2020 capital budget and plan of finance
with a budget of $2,000,000. The scope and budget were increased to include Concourse A. The
budget increase will be transferred from the Aeronautical Allowances CIP (C800404). The

Lifecycle Cost and Savings 
The proposed carpet tile system is not expected to have significant repair costs in the first 5
years. Preventative maintenance costs will be consistent with the current maintenance program. 
The average life expectancy for carpet in public areas of the airport is 6-7 years. 
STRATEGIES AND OBJECTIVES 
This project supports the Century Agenda strategy of "advancing this region as a leading tourism
destination and business gateway" by providing targeted improvements tothe hold rooms of
Concourse A, B and C. Improving airport conditions such as carpeting will improve the
passenger perceptions of Sea-Tac and help us reach a key goal of the Century Agenda  to be the
west coast gateway of choice for international travel. 
This project also supports the Aviation Division strategy to become one of the top customer
service airports in the world. The style and perceived cleanliness of carpet in hold rooms (where
dwell time is often significant) contributes to the quality of the overall passenger experience in
the terminal.

This project supports the Century Agenda strategy to be the greenest Port in North America by
recycling the existing carpet material to the extent feasible. In addition , the project will install
new carpet containing recycled materials and will minimizing the use of volatile organic
compound containing materials.
Elements of the scope of work associated with the construction and installation of the new carpet
tile system support the utilization of small business to participate on this project. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Status Quo  Do not replace the carpet at this time. While the carpet does need
to be replaced, it could be deferred for one or two years. 
Capital Cost: $0 in 2016, but $3.636 million plus escalation in either 2017 or 2018. 
Pros: 
No capital investment. 
Cons: 
Retaining the existing carpet will require continued maintenance, likely on a more
frequent basis, as the carpeting continues to deteriorate. 
The carpet on Concourses A, B and C is 10 years old, worn stained and unsightly. 
This alternative perpetuates an impression that our hold rooms are dirty. 
This alternative does not respond to airline customers requests to replace carpet 
This is not the recommended alternative. 
Alternative 2  Replace Carpet with In-Kind Roll Carpet 
Cost Implications: $3,771,000.00 [carpet $12.25 per square foot] 
Pros: 
Old stained carpet is replaced with new in-kind roll carpet greatly improving the
aesthetics of the concourse. 
A slightly quicker installation process than carpet tile (Alternative 4) 
Cons: 
Requires a capital investment 
Slightly higher cost per square foot than carpet tile system (Alternative 4) 
When patched, the patched areas can be difficult to match up with the surrounding
pattern and can also fray easily. 
Left over carpet for future repairs (called "attic stock") in rolls is bulky and more
challenging to store than carpet tile that is typically delivered in smaller boxes. 
This is not the recommended alternative.

Alternative 3 Replace Carpet on Concourse A, B, and C with Terrazzo 
Cost Implications: $15,000,000 [Approximately $54 per square foot] 
Pros: 
Old stained carpet is replaced with terrazzo greatly improving the aesthetics of the
concourse. 
Terrazzo flooring system provides a more permanent and durable solution than
carpet. 
Cons: 
Terrazzo requires a significantly higher capital investment than carpet alternatives. 
Installing terrazzo on Concourse A, B and C would add more than a year to the
project. Installation would require each site to be isolated from the public and
separately ventilated. 
Terrazzo's hard surfaces reflect sound while carpeting's soft surfaces absorb sound.
Replacing carpeting with terrazzo increases the acoustic reflectivity making gate 
hold rooms very noisy.
This is not the recommended alternative. 
Alternative 4  Replace Carpet on Concourse A, B, and C with Carpet Tile System 
Cost Implications: $3,661,000.00 [carpet $12.19 per square foot] 
Pros: 
Slightly lower cost per square foot than roll carpet alternative 
Old stained carpet is replaced with carpet tile system greatly improving the
aesthetics of the concourse. 
Carpet tile system provides better solution for replacing stained or damage areas of
carpet in the future as stained tiles can be quickly replaced and cleaned. 
Attic stock is easier to maintain than rolled carpet. 
Cons: 
This option requires a capital investment 
Installation can be slower than a rolled carpet alternative 
This is the recommended alternative.
