ACTION ITEM                            Date of Meeting      October 12, 2021 

DATE:     September 10, 2021 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Laurel Dunphy, Director Airport Operations 
Nora Huey, Director of Central Purchasing Office 
SUBJECT:  Portable Restrooms, Airport Landside Operations 
Amount of this request:               $1,500,000 
Total estimated project cost:          $1,500,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute a contract for an
estimated value of $1,500,000 for the provision of portable restroom services for the Ground 
Transportation lots, the Cell Phone lot at SEA Airport and other various Port locations, with a
Contract Length of One (1) Year with Two (2) One-year Options for Renewal. 
EXECUTIVE SUMMARY 
The Port of Seattle supports a variety of transportation modes at SEA Airport (Airport) and other
Port locations. As part of the ongoing effort to provide amenities to public customers and
commercial ground transportation operators, the airport's Landside team coordinates a contract
for portable restroom and hand washing facilities. The airport team has managed the current
agreement since 2018 and recognizes the continuing need. The annual expenses for Aviation 
Landside Operations for portable restrooms services are projected to be in the amount of 
$275,000 for the October 1, 2021 to September 30, 2022 time period, and $350,000 each for the
second and third years of this contract resulting in a 3-year anticipated expenditure in the
amount of $975,000. Portable restrooms are also essential in other operating areas that do not
have permanent restroom facilities. These requests are usually ad-hoc and are for immediate use
due to unplanned circumstances.  Thus, CPO recommended adding $525,000 in additional
contract capacity to cover unanticipated needs of other Departments.  The total estimated 
contract value for portable restroom services is $1.5 million.
JUSTIFICATION 
This contract will provide portable restrooms for commercial operators and the traveling public
at the Airport and other Port locations. Sanitation facilities are essential to providing high levels
of customer service and maintaining public health.

Meeting Date: October 12, 2021 
There has been a consistent demand for restroom facilities at Landside properties. While demand
has fluctuated with passenger activity, it's anticipated that both commercial and passenger
activity levels will increase in 2022 and 2023 and the number of portable restrooms needed will
increase as well.
DETAILS 
The table below describes anticipated spending for portable restrooms in Landside Operations 
and other Port locations for each contract year from October 1, 2021 to September 30, 2024.

Year 1             Year 2            Year 3           (A+B+C) 
Landside Operations      $275,000         $350,000        $350,000        $975,000 
Other Port Locations      $175,000          $175,000         $175,000        $525,000 
Combined Total      $450,000         $525,000        $525,000       $1,500,000 

Note: The contract year is October 1 to September 30. The anticipated spending amount for
2021 is based on current activity.  Spending levels for 2022 and 2023 are based on projected
activity. Projections are based on current rates. Rates are subject to change if a new vendor is
awarded this contract. The Port issued a short-term change order to extend the contract until
December 31, 2021. No additional money was needed to cover this time period. 
In July 2018, the Commission authorized $2,040,000 to execute a contract for portable
restrooms. The requested amount in 2018 included $600,000 for other Port divisions to request
portable restrooms. The Port may still have needs outside of the airport and for efficiency we 
recommend a port-wide contract. CPO will work with Aviation to put into place an appropriate
management system to address other Division needs. 

Scope of Work 
This contract will cover all Port locations. Landside Operations plans to provide portable
restrooms at the following Airport locations: 
(1) Cell Phone Lot (2 units in 2021, 4 units in 2022 and 2023) 
(2) 160th Street TNC Holding Lot (4 units in 2021, 7 units in 2022 and 2023) 
(3) Taxi Feeder Lines on 3rd Floor of the Garage (2 units) 
(4) Cruise Bus Lot (2 units) 
(5) Port Valet bag sort location (1 unit)
