ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to execute a design contract
and prepare design and construction bid documents for the Restroom Upgrades at Concourses B,
C, and D project at Seattle-Tacoma International Airport for an estimated $5,032,000 of a total
project cost of $33,047,000. 
SYNOPSIS 
This project will renovate, enlarge and build new public restrooms on Concourses B, C, and D at
the Airport. These restrooms have not been remodeled since 1992 and 2001. This project was
originally intended to make renovations to the existing restrooms. Because of passenger traffic 
growth, the existing restrooms are too small resulting in long lines during peak periods of use.
The project scope was increased to include additional restroom capacity. 
Restrooms included in this project are the oldest and most deteriorated in the Airport. As Airport
planning proceeds the restrooms in the main terminal, which were mainly refurbished in the
early 2000s, will be evaluated and a determination of their condition and capacity will be
performed to determine if upgrades are required. 
BACKGROUND 
In 1992 the Airport completed a major remodel of Concourses B, C, and D and constructed the
concourses'  public restrooms. That year  the Airport accommodated  16  million annual
passengers. Today traffic exceeds 42 million annual passengers. There are frequently lines at
many of these restrooms during peak travel periods due to their size and the increased passenger
traffic.

Page 2 of 8 
In the late 1990's the Port embarked on a multi-year project of restroom remodels in the Main
Terminal and the North and South Satellites. While some minor updates were completed for a
few of the restrooms on Concourses B, C, and D, most have not been renovated or enlarged. 
The Concourses B, C, and D restrooms are old, outdated, and overcrowded. They are difficult to
maintain due to the age of the finishes and fixtures, water infiltration and damage, limited air
circulation and odors that have penetrated the finishes. Of the existing eight pairs of restrooms, 
three have not been remodeled since 2001, and five have not been renovated since their
construction in 1992. 
In 2015, Port staff undertook a study to determine future restroom capacity needs. The study
utilized guidelines from the 2015 Airport Cooperative Research Program (ACRP) Guidebook for
Airport Terminal Restroom Planning and Design. These ACRP guidelines allowed staff to
calculate the optimal number of toilet fixtures required for each concourse based on a number of
factors including, 1) the type of aircraft that gate on each concourse (fleet mix); 2) the number of 
seats filled on these aircraft (load factor); and 3) the number of aircraft loading and unloading
passengers at the same time during peak periods (gate utilization). This study recommended
increasing the total number of fixtures for each concourse as follows: 
Location         Existing Fixtures      Recommended    Total To Be Provided 
Concourse B              50              93             91 
Concourse C               63              91             91 
Concourse D              50             73             73 
During the summer of 2015 electronic and manual counts of restroom use were also collected.
These counts confirmed that there are lines of people waiting during several hours per day at
many of our restrooms. The suggested square footage of restroom expansion in this project is
aligned with these industry standards and observations of current conditions. On concourses
where even more square footage could be identified for potential use, staff is recommending
additional restroom amenities such as nursing mother's rooms and pet relief areas. These
facilities are important to the traveling public and many other airports are providing them as
well. 
PROJECT JUSTIFICATION AND DETAILS 
The Airport has conducted quarterly customer satisfaction surveys using Airport Service Quality
(ASQ) since 2011. Under the quality service area of "restroom cleanliness," the Airport has
consistently under-performed relative to the top 25 North American peer airports. The lower
customer satisfaction ratings can be attributed to the worn and outdated restrooms. Although
restrooms are cleaned regularly, customers perceive the Airport restrooms as being unclean due
to their age and condition. The ASQ results show that the availability and cleanliness of airport
restrooms are very important. Restrooms are often the last place customers visit before their
flights depart and the first place passengers visit when their flights arrive.

COMMISSION AGENDA 
Ted Fick, Chief Executive Officer

Growing passenger numbers means many restrooms have lines of travelers waiting to use the
facilities during peak times. This project will address capacity needs by developing additional
restroom space. Because of the limited vacant space available in the public areas, this project
will relocate tenants and construct building additions in order to enlarge restrooms. 
Beyond cosmetic  updates that make the restrooms more comfortable and appealing to
passengers, recent work in these restrooms has revealed that water has infiltrated behind walls
and under floor tiles. This has led to rusted and in some cases failed wall studs, loosening floor
tile and standing pools of water. 
Project Objectives 
The project's objectives are to improve capacity and ASQ scores for Concourses B, C, and D and 
to decrease Operations and Maintenance (O&M) costs for restrooms. 
Scope of Work 
The project will renovate eight restrooms on Concourses B, C, and D. This project will increase
restroom capacity by increasing the size of two existing restrooms; building new restrooms
displacing existing tenant functions, and enlarging the building to add one additional new
restroom. The scope will build new tenant space; relocate tenants; demolish existing restrooms to
the framing; art relocation,  storage and reinstallation; new piping;  waterproof membrane;
plumbing; fixtures; and restroom accessories i.e. hand dryers, soap dispensers; new flooring,
lighting, and partitions. 
Concourses B and C have two sets of restrooms and Concourse D has four sets. Construction
will be phased at each concourse to ensure one or more sets of restrooms will be available while
other sets are under construction.

Budget Status and Source of Funds 
This project, CIP #C800697 was included in the 2016-2020 capital budget and plan of finance
with a budget of $11,180,000. The project scope and budget were increased as follows: 1)
signage, art impacts, and janitor's closet modifications were added to the project for a budget
increase of $2,020,000; and, 2) provisions for new restroom capacity were added to the project
also for a budget increase of $19,847,000. The capital budget increase of $21,867,000 was
transferred from the Aeronautical Allowance CIP (C800404) resulting in no net change to the
Airport capital budget. The funding source will be the Airport Development Fund and future
revenue bonds.

Lifecycle Cost and Savings 
Currently a project is underway to standardize the fixtures and finishes for the Airport restrooms.
The O&M project to improve costs related to restrooms was identified as a viable project to go
through the LEAN Continuous Process Improvement (CPI) efforts and is nearing completion and 
the implementation of streamlined processes. While many efficiencies have been identified for
implementation in the on-going O&M performed by the Airport, a new goal has been established
related to 'all restrooms being 100% ready by 4:00 a.m. each day'. Standardization and LEAN
process improvement efficiencies will decrease Airport O&M, but the new standard of having
the restrooms fully functional each morning may offset this decrease. The scope of the project
has expanded to include both renovation of existing restrooms as well as constructing additional
restrooms due to the increased passenger volumes and the resulting capacity need which will
increase O&M costs.

COMMISSION AGENDA

A compilation of the impacts (increases & decreases) in Airport O&M can be better estimated
during the design phase of the project at which time all stakeholders will be involved in the final
standardization decisions. 
STRATEGIES AND OBJECTIVES 
This project supports the Century Agenda strategy of "advancing this region as a leading tourism
destination and business gateway" by improving the public restrooms on Concourse B, C, and D.
Improving Airport restroom conditions will improve the passenger perceptions of Sea-Tac and
help reach a key goal of the Century Agenda  to be the west coast gateway of choice for
international travel. 
This project supports the Century Agenda by minimizing the Airport's environmental footprint
by conserving water through installing low flow toilets, urinals and fixtures. 
The condition of restrooms and cleanliness ranks in the top three of importance to Sea-Tac
customers as measured by the ASQ. This project supports the Aviation Division's strategic goal
to increase Overall Customer Satisfaction score in the ASQ. This project is directly linked to the
Aviation Division's ability to increase customer satisfaction. Restroom cleanliness and
availability contributes to the quality of the overall customer experience. 
This project has collaborated with the Economic Development's Small Business Group to
maximize small business participation throughout the design by using a 20% small business
participation goal. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Status Quo  Keep restrooms as they are today. Do not remodel or expand. 
Cost Estimate: Capital $0  Expense $145,000 yearly 
Pros:
No capital investment. 
No closure of public restrooms for renovation. 
Cons: 
The restrooms will continue to be impacted by their high use. 
This alternative would do nothing to improve the passenger experience in the restrooms
and Sea-Tac's ASQ scores on restroom cleanliness would likely continue to decrease as
the restrooms age and wear. 
This alternative would not solve problems behind walls (rusted studs, pooling water) and
under flooring (water penetration), that have continuously deteriorated these restrooms
due to lack of waterproof membrane to keep leaking water out. 
This alternative does not solve issues with odor and surfaces appearing unclean due to
wear and tear.

COMMISSION AGENDA 
Ted Fick, Chief Executive Officer

The lavatory hangers installed in these restrooms do not support updated porcelain and
fixtures adequately. Fixtures will begin falling off of the walls. 
This is not the recommended alternative. 
Alternative 2)  Update restroom finishes and fixtures only without tearing out walls and
undertaking a complete renovation or addressing capacity issues. This alternative would include
new toilets, urinals, sinks, flooring, hand dryers/paper towel holders, soap dispensers and stall
enclosures. 
Cost Estimate: Capital $7,970,000   Expense $39,000 yearly 
Pros: 
Limited capital investment compared to full renovation and shorter closure of restrooms. 
Cons: 
This alternative would not solve problems behind walls (rusted studs, pooling water) and
under flooring (water penetration), that have continuously deteriorated these restrooms
due to lack of waterproof membrane to keep leaking water out. 
This alternative will not allow fixture counts to be optimized. 
This alternative does not address capacity issues. Lines would continue to form and ASQ
scores would likely be impacted. 
This is not the recommended alternative. 
Alternative 3)  Renovate existing restrooms, tearing out walls, and undertake a complete
renovation. This alternative would include new toilets, urinals, sinks, flooring, hand dryers/paper
towel holders, soap dispensers and stall enclosures. 
Cost Estimate: Capital $13,047,000  Expense $0 
Pros: 
This alternative provides the opportunity to rebuild Sea-Tac's public restrooms to a
higher standard to handle the high volume of use they receive. 
This alternative also provides the opportunity to explore innovative restroom design that
incorporates environmental sustainability, and is pleasing the customers. New finishes are
generally easier to keep clean, and odor free. Less maintenance is required for new
fixtures than older fixtures. 
Renovating these restrooms is the only likely way to improve ASQ scores in the restroom
category. 
This project provides the opportunity to install low flow toilets, urinals, and faucets to
conserve water resources in the restrooms related to this project. 
Completely demolishing and renovating the existing restrooms will assist in preventing
further damage to the facility caused by water leaks within the existing wall cavities.

This alternative includes signage, art impacts and janitor's closets that were not included
in the original scope. 
Cons: 
This alternative is not intended to substantially improve capacity issues. 
This alternative involves closing restrooms for long period of time, up to 10 months at a
time for renovation, which will exacerbate our current problem with demand exceeding
availability. 
This is not the recommended alternative. 
Alternative 4) Renovate and enlarge existing restrooms and build new restrooms to address
capacity. 
Cost Estimate: $33,047,000 
Pros:
This alternative provides the opportunity to rebuild Sea-Tac's public restrooms to a
higher standard to handle the high volume of use they receive. 
This alternative provides an opportunity to increase restroom capacity. 
This alternative provides the opportunity to explore innovative restroom design that
incorporates environmental sustainability, is pleasing the customers and also easier to
maintain. 
Renovating these restrooms and adding capacity is the only likely way to improve ASQ
scores in the restroom category. 
This project provides the opportunity to install low flow toilets, urinals, and faucets to
conserve water resources in the restrooms related to this project. 
Completely demolishing and renovating the existing restrooms will assist in preventing
further damage to the facility caused by water leaks within the existing wall cavities. 
This alternative provides an opportunity to explore the efficiencies of gender neutral
restrooms. 
Cons: 
This alternative involves closing restrooms for long periods of time, up to 10 months at a
time for renovation, which will exacerbate our current problem with demand exceeding
availability. 
In order to gain space on the concourse level several enabling projects must be completed
and various airline office functions will need to be relocated. 
Building space for and vacating space currently leased adds time to the project delaying
improvement, which are needed now. 
This is the recommended alternative.
