SUBJECT:  Enhanced TSA Checkpoint and Baggage Screening Area Cleaning 
Amount of this request:              $2,700,000 
Total estimated project cost:          $2,700,000 
ACTION REQUESTED 
Request Commission Authorization for the Executive Director to: amend a service contract for
Airport Custodial Services to provide enhanced cleaning and sanitation for Transportation
Security Administration (TSA) Checkpoints and Baggage Screening Areas as requested by the TSA. 
The additionally requested cleaning and sanitization work is estimated to cost $2.7 million. 
EXECUTIVE SUMMARY 
The TSA has requested enhanced cleaning at Checkpoints and Baggage Screening Areas under
their purview to reduce the risk of COVID-19 transmissions. The service is requested to start
immediately upon approval and is currently scheduled to end on December 31, 2020. 
The TSA funding has been appropriated and TSA has established a reimbursement process for
airports that experience an increased cleaning and sanitization requirement based on the
enhanced TSA requirements, including proactive custodial  services to mitigate COVID-19
transmission. All reimbursements must receive TSA approval. 
JUSTIFICATION 
Congress, as part of the "Coronavirus Aid, Relief, and Economic Security Act" or the "CARES Act"
has appropriated supplemental funding to pay for requested enhanced cleaning and sanitation
of TSA Checkpoints and Baggage Screening Areas in alignment with the local and state health
department and the Centers for Disease Control and Prevention (CDC) guidelines for COVID-19.

TSA has published specific cleaning/sanitization and frequency standards for enhanced cleaning
and sanitation of the security checkpoints and baggage screening areas. This cleaning is
supplemental to the daily/nightly general cleaning. These standards include specific tasks and
cleaning frequencies requested by TSA that are above the standard cleaning performed by the
Airport. 
The additional cleaning and sanitation  effort  is in alignment with and supported by our
FlyHealthy@SEA strategy, and is expected to assist in returning customer confidence in air travel.
The enhanced services would be a visible reminder regarding cleanliness and sanitation level of
the high touch point items and services at the Checkpoints. 
DETAILS 
The cost for the additional cleaning and sanitation will be reimbursed by TSA through the CARES
Act. The most impactful task among the requested cleaning and sanitation tasks is a request for
hourly sanitation of Divestiture Bins/Bowls. This labor-intensive requirement generates the need
for a full-time employee at each screening lane operating during the operation hours. Those
operational hours can range from 8 hours to 24 hours per lane.  This task accounts for
approximately 93% of the costs. 
The cost estimate of $2,700,000 is a conservative estimate, based on an estimated 20 lanes being
in operation approximately two and one-half shifts per day on average. Costs incurred will be
based on actual hours of service performed. TSA reimbursements will be based on these actual
costs as well. 
The port is seeking quotes from the two existing custodial service providers. Rational for the
limited competitive process is due to the immediate need to start the cleaning service and that
the current custodial service providers are familiar with the airport, have staff already badged
and onsite. Staff will be receiving quotes and are awarding after taking all applicable criteria into
consideration (price and staff availability). 
Airlines are supportive of this enhanced service to raise the confidence of their customers in
traveling through Seattle-Tacoma International Airport (SEA). 
Scope of Work 
The detailed scope of work as requested by the TSA is attached at the end of this memo.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Provide only the general cleaning that would not cost additional expense
Cost Estimate: $0.00 
Pros: 
1.  This alternative eliminates the need to modify the contracts and manage through the
CARES Act reimbursement process, which will require Port resources to complete.
Cons: 
1.  This approach does not help in the effort to improve customer confidence in air travel. 
2.  The opportunity would be missed to enhance the services at SEA that will be
experienced at other airports.
This is not the recommended alternative. 
Alternative 2  Amend and execute the contract only to provide the bin and bowls cleaning and
sanitization 
Cost Estimate: $2.55 million (to be reimbursed by TSA through the CARES Act) 
Pros: 
1.  This alternative provides a significant portion of the enhanced services as requested
by TSA, providing the visible reminder regarding the cleaning and sanitation of bins
and containers used at TSA checkpoints.
2.  This  alternative  supports  the  FlyHealthy@SEA  strategy  to  enhance  customer
confidence in flying through SEA.
3.  This alternative aligns with the requirements of the TSA, allowing for the
reimbursement of these costs through the CARES Act reimbursement process.
Cons: 
1.  This alternative does not provide the full level of enhance service at all the high touch
points or surfaces in all areas of the checkpoints. 
2.  This alternative creates demand for Port resources to manage the contracts and the
reimbursement process that the Port did not forecast or plan for. 
This is not the recommended alternative.

Alternative 3 - Amend and execute a service contract for enhanced services to provide TSA all
requested additional cleaning and sanitation at checkpoints and baggage screening areas. 
Cost Estimate: $2.7 million (to be reimbursed by TSA through the CARES Act) 
Pros: 
1.  This alternative allows for the contractor to provide the full suite of enhanced services that
TSA requested under the local/state and CDC requirements providing the visible reminder
regarding the cleaning and sanitation of bins, containers and surfaces used at TSA 
checkpoints.
2.  This alternative supports the FlyHealthy@SEA strategy to enhance customer confidence in
flying through SEA.
3.  This alternative aligns with the requirements of the TSA, allowing for the reimbursement of
these costs through the CARES Act reimbursement process.
4.  Cons: 
5.  This alternative creates demand for Port resources to manage the contracts and the
reimbursement process that the Port did not forecast or plan for.
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
Annual Budget Status and Source of Funds 
The additional custodial costs authorized by this request will increase the Aviation operating and
maintenance costs for 2020 by $2.7 million.  Since the Port assumes these costs will be
reimbursed by TSA, there will be no net increase to airline costs (CPE) and no impact on the Port's
net income.
