ACTION ITEM                            Date of Meeting        July 24, 2018 
DATE:     July 16, 2018 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Michael Ehl, Director Aviation Operations 
Jeffrey Hoevet, Senior Manager Airport Operations 
SUBJECT:  Portable Restrooms, Airport Landside Operations 
Amount of this request:               $2,040,000 
Total estimated project cost:          $2,040,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to advertise and award contracts
in the amount of $2,040,000 for the provision of portable restroom services primarily at ground
transportation locations at Seattle-Tacoma International Airport. This contract will be for one
year with two one-year options. 
EXECUTIVE SUMMARY 
Combined, Sea-Tac Airport Landside Operations' annual expenses for portable restroom
services are projected to be about $480,000 in 2018 which exceeds the budgetary limits
delegated to the Executive. Staff recommends consolidating portable restroom services under a
single, open-order contract with sufficient capacity to satisfy Landside Operations' business
requirements for three years.  The contract shall be written with enough flexibility to allow
other Port Divisions to utilize the contract if needed. 
JUSTIFICATION 
This contract will provide portable restrooms for commercial operators and the traveling public
at Sea-Tac Airport and other Port locations. Sanitation facilities are essential to providing high
levels of customer service and maintaining public health. 
The number of portable restrooms leased by Sea-Tac Landside Operations has increased during
the past two years due to the six-fold increase (from 2,000 to 12,000) in the number of
commercial operators at Sea-Tac Airport, and the 10 percent increase in the number of
passengers. 
The Transportation Network Companies (TNCs) staging lot requires the largest number of
portable restrooms as the TNC lot is full almost 20 hours per day.  The Port has already

Meeting Date: July 24, 2018 
responded to a Labor and Industries (L&I) complaint made regarding the facilities in the TNC
lot.  With the 7 units provided, the Port has met the Washington Administrative Code 296-800-
2320 requirement for portable restrooms. 
The requested contract amount includes additional margin--about $200,000 per year--for other
Port Divisions to request portable restrooms when needed. The recommended alternative calls
for an open order contract that means the Port may spend up to $2,040,000 or less depending
on the need. 
DETAILS 
The table below describes anticipated Landside Operations spending for portable restrooms
from 2018 to 2020 and the amount of contract capacity left for other Port Divisions.

Note:   Projected spending levels are based on current activity and restroom distribution patterns. 
Significant programmatic changes are not anticipated during the contract duration. 
Once Commission approval is received, the Port will issue solicitation in July 2018 with
anticipated start date in Q4 2018. 
Scope of Work 
At a minimum, provide and service portable restrooms at the following locations: 
Cell Phone Lot (4 units) 
160th Street TNC Holding Lot (7 units) 
160th Street Taxi Staging Lot (2 units) 
Taxi feeder lines on 3rd floor of the garage (2 units) 
Charter Bus Lot (2 units) 
Port Valet location (1 unit) 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Discontinue Service 
This option would remove all portable restrooms and cease services to all Airport facilities. The
current purchase method is unsustainable and could lead to a violation of Port policy. Instead
of exceeding the limits of Executive power, Port staff would discontinue service to the Airport's

facilities. This action may result in significant negative public reaction, increased hazardous
waste and non-compliance with L&I requirements. 
Cost Implications: $0 direct cost to implement this option 
Pros: 
(1)   Cessation of portable restroom service prior to exceeding the $300,000 threshold is
consistent with Port procurement policies 
Cons: 
(1)   Significant reduction in customer service at public-facing remote lots like the Cell
Phone Lot 
(2)   Increased likelihood of uncontained hazardous waste in remote lots 
(3)   Out of compliance with Washington State L&I standards for basic employee sanitation
facilities 
This is not the recommended alternative. 
Alternative 2  Request for Proposals 
This option would authorize the Executive Director to enter into agreements with a portable
restroom services provider to support Airport operations in the Cell Phone Lot, 160th Street
Ground Transportation  Lot, Charter Bus Lot, and other areas. Approving this option
consolidates portable restroom purchases under one open order contract with sufficient
capacity to meet Landside Operations' needs for the next three years and support other Port
Divisions' portable restroom needs. 
Cost Implications: $0 direct cost to implement this option 
Pros: 
(1)   Maintain consistency with Port of Seattle procurement policies 
(2)   Comply with Washington State L&I facilities standards 
(3)   Provide continuity of operationsexisting practice is unsustainable on a policy basis
and eventually requires an abrupt end of service without remedy 
(4)   Formalize contractor business requirements such as billing intervals and rates 
(5)   Opportunity to lower existing service rates due to competitive process 
Cons: 
(1)   Possible marginal increase in time to process paperwork and apply charges against the
contract limit 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
Annual Budget Status and Source of Funds 
Portable restrooms are an on-going operating expense for the Airport's Public Parking and
Ground Transportation operations and affect net operating income. No new or supplemental

funds are requested as part of this action. The actual costs incurred under this contract will be
included in annual operating budgets. 
Future Revenues and Expenses (Total cost of ownership) 
This request addresses an immediate need; portable restroom expenses will continue to affect
net operating income from both Ground Transportation and Public Parking operations at the
Airport in the near term.
