SUBJECT:  Airport Janitorial Service  Zone 1 

Contract Amendment:                   $341,740 
Total Amount of Contract:               $4,843,681 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to amend the service contract for
Seattle-Tacoma International Airport Janitorial Service in the existing Zone 1, consisting of
Concourse A, Concourse B, and South Satellite, increasing the contract value by $341,740. 
EXECUTIVE SUMMARY 
December 2019 marked the end of the second year of the four current custodial contracts at the
Seattle-Tacoma Airport (Airport). This also marks the end of the initial contract commitment
period on behalf of the contractors and the Port of Seattle. This two-year period, in combination
with passenger growth beyond 10% of the 2016 passenger enplanement levels, also triggered an
opportunity for the contractors and the Port to request adjustments to the contract values in
each of the zones. 
Over the past nine months, Port staff has been working with our service providers to address
their ability to meet the elevated standards implemented in the newest RFP, as well as the
challenges created by the continued strong growth in passenger traffic at the Airport. Through
these discussions and negotiations, Port staff and our Zone 1 contract service provider, C&W
services, have reached an agreement on a recommended increase in the value of the contract
for the year 2020 of $341,740. Most of the increase in funding is for additional staff and wage
adjustments. A small portion, approximately 5%, is for additional custodial supplies. 
Airport Staff is only requesting additional funding for 2020 while they continue to evaluate
options for 2021 and beyond. Staff may return at a future date to request contracting authority 
to execute a 2021 contract extension or may determine the execution of a new RFP for Zone 1
for 2021 and some years beyond is most appropriate.

COMMISSION AGENDA  Action Item No. 6c                                   Page 2 of 6 
Meeting Date: February 11, 2019 
Approval of this request will allow for the extension of the service contract for the full year of
2020 based on the current performance-based contracting model used in the balance of the
Airport facility. The amendment allows staff to a djust the value of the contract to better align
with actual costs, both wage and materials, necessary to meet the Airport's contractual standards
under these increased passenger demands. 
JUSTIFICATION 
The facility needs to be clean and well maintained to meet the Port's customer service and
cleanliness standards in support of the Port's Century Agenda goal to advance as a leading
tourism and business gateway of choice on the West Coast. 
DETAILS 
On September 27, 2016, Commission authorized the then CEO to execute up to four contracts
for custodial services at the Airport for up to five years, with an estimated total cost of
$80,000,000. From January 2018 through December 2019, approximately $33,400,000 has been
spent on the custodial contracts. Following that 2016 Commission approval, an extensive RFP
process was conducted to solicit bid for custodial services in each of the four zones. The result of
this process generated four contracts providing custodial services, spread amongst three
contractors. These contracts were executed in the fourth quarter of 2017, with a starting date of
January 1, 2018. This procurement methodology was significantly different from the previous
methods.  Previously a single contractor was responsible for the entire facility.  The new
methodology was intended to provide continued competition. In addition, significantly more
stringent cleanliness standards and a larger small business element was incorporated. 
The original procurement provided the four contracts to have a two-year initial contract duration
with the opportunity to renew any of the contracts for up to an additional three years in oneyear
increments. In addition, the RFP provided methodology to allow the Airport to transition
from one of the initially selected contractors to another at the time of contract renewals if
deemed necessary and appropriate. This initial procurement resulted in three prime contractors
being awarded the four zone contracts. 
As a result of that competitive process, C&W Services was awarded the contract for custodial
services in what has been identified as Zone 1, consisting of Concourses A and B and the South
Satellite. 
Through growth related triggers incorporated into the RFP, the opportunity was afforded to the
contractors after the initial two-year contract, and an enplanement growth of greater than 10%
from year end 2016, to request contract value adjustments. C&W Services elected to make the
request to adjust the contract value for Zone 1. 
With now nearly two years of experience under this contracting model, both Airport staff and
C&W staff have more information available to quantify and justify the need for any adjustments

to the contract value. C&W services has been very transparent as to what adjustments in staffing
and materials they determined would be necessary to allow them to meet the Airport standards
while allowing them a reasonable profit. Airport staff has worked with C&W staff to evaluate and
adjust the request. Through this  lengthy negotiation process,  staff  determined  the most
reasonable path forward for the Airport, for 2020, would be to renew with C&W Services for Zone
1. The value of the increase negotiated for Zone 1 is in the amount of $341,740. As this is an
amendment to an existing contract, and the value exceeds $300,000, the request exceeds the
delegation of authority for the Executive Director and requires Port Commission approval. 
ADDITIONAL INFORMATION 
Adjustments in Zones 2 and 3 were also necessary, but due to their size, or contracting
mechanisms built into the original contract, those changes do not require Commission action.
One of the levers built into the original RFP provided the Airport to transition from one of the
existing contractors to another existing contractor at time of renewal. This was intended to
provide staff with the flexibility necessary to make contractor changes when appropriate. In the
interest of transparency, however, Airport Staff is including information about those changes. 
In accordance with the original Commission authorization of September 27, 2016, and the
solicitation published in 2016 for janitorial services, the Port did not exercise the option term for
the Zone 2 contractor and awarded a new Zone 2 contract on December 24, 2019 to C&W
Services. This did not result in an increase in the contracting authority approved by Commission. 
As a result of the competitive process, C&W Services was also awarded the contract for custodial
services in Zone 3, consisting of the non-secure public areas of the facility including the curbsides
to the checkpoints on the ticketing level and the curbsides through the baggage claim level. 
Through growth related triggers incorporated into the RFP, the opportunity was afforded to the
contractors after the initial two-year contract, and an enplanement growth of greater than 10%
from year end 2016, to request contract value adjustments. C&W Services elected to make the
request to adjust the contract value for Zone 3. 
The value of the increase negotiated for Zone 3 is $290,100 and falls within the delegation of
authority for the Executive Director to execute this amendment. As such, no Commission action
is required. 
Through the competitive process, Whayne Enterprises, a Small Business Partner, was awarded
the contract for Zone 4, which consists primarily of non-public spaces such as the Airport Office
Building, remote port facilities, and the back-of-house areas such as the bagwell. There was no
adjustment required for Zone 4. 
Airport staff will be returning to Commission in the near future to request authorization for future
procurements for each of the four zones contracted through the initial 2017 four-zone

procurement. Staff anticipate staggering those procurements through 2020, 2021 and potentially
2022. 
Scope of Work 
The scope of work for the Zone 1 custodial services contract with revisions includes all elements
of the original RFP executed in 2017, adjusted for the actual increase in labor and materials cost
as a result of inflation, alignment with current labor rates, and passenger growth. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not provide the additional $341,740 for the additional labor and material
resources for Zone 1. Utilize the existing value of the contract without amendment for growth
and changed business conditions. 
Cost Implications: Zero additional dollars for Zone 1. 
Pros: 
(1)   This alternative saves the Airport $341,740. 
(2)   No contract amendment is required. 
Cons: 
(1)   The contractor will be unable to enlist additional staff deemed necessary to meet the
quality standards of the Airport. As a result, the customer experience will be negatively
impacted. 
(2)   This alternative would eliminate an existing  lever used  by Airport staff to drive
performance in a positive quality direction. 
This is not the recommended alternative. 
Alternative 2  Execute a multi-year change order for Zone 1. 
Cost Implications: Range of $600,000 to $800,000 cost increase for Zone 1 over multiple years.
Pros: 
(1)   This alternative provides more time to execute a new RFP for Zone 1, if the airport chose
to do so. 
(2)   This alternative could eliminate a need for a future necessary Commission action, if
Airport staff determined the best approach for 2021 was to renew with the current
contractor for Zone 1.
Cons: 
(1)   While  Airport  cleanliness  has  improved  despite  increased  demands,  the  Airport
cleanliness level expected has not yet been achieved in any of our zones. As such, staff 
do not yet feel it is appropriate to commit to a contractor beyond 2020. 
(2)   This alternative is the highest cost of the alternatives identified. 
This is not the recommended alternative.

Meeting Date: February 11, 2019 
Alternative 3  Execute a contract amendment for $341,740 for Zone 1 custodial services. 
Cost Implications: $341,740.23 
Pros: 
(1)   This alternative allows for continuity of service with the service provider for Zone 1,
limiting the complexities of multiple transitions in a short period of time. 
(2)   This alternative provides the level of financial resources identified by the service
provider that they feel will allow them to properly resource Zone 1 and meet the
Airport's standards. 
(3)   With this mutually agreed upon increase, a lever is provided to Airport staff to hold the
service provider accountable to meeting the Airport standards. This increase eliminates
barriers and excuses the contractor may otherwise leverage to explain away poor
performance. 
Cons: 
(1)   This alternative only addresses a contract increase for one year. If it is determined in
2020 that this approach is a successful one, a negotiation and potential Commission
action may be required to execute an amendment for 2021. This will require some level
of duplication of effort. 
(2)   This alternative is more costly than Alternative 1. 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
Annual Budget Status and Source of Funds 
Janitorial costs are included in Aviation Maintenance's annual operating budget, so the funding
source will be the Airport Development Fund. The increases discussed in this memo were not
known when the 2020 budget was developed and therefore not included.  The contract
amendment amount ($341,740) and the other adjustments for 2020 (not requiring Commission
action) total approximately $1.79 million. The Aviation division will strive to absorb these
additional costs within the 2020 approved operating budget.
