SUBJECT:  Concourse A Building Expansion for Lounges (CIP #C801205) 
Amount of this request:                $6,180,000 
Total estimated project cost*:         $71,400,000   *
* Cost estimate is based on Delta Air Lines current cost estimate, not a Port of Seattle estimate 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) authorize $6,180,000 of
design budget including a reimbursement to Delta Air Lines, Inc., for the design of the Concourse
A Building Expansion for Lounges project at Seattle-Tacoma International Airport; and, (2)
execute a Tenant Reimbursement Agreement (TRA) with Delta for this purpose under the
Airport's AV-2 Policy. 
EXECUTIVE SUMMARY 
This project includes a building expansion towards the end of Concourse A, to predominately
house a new passenger lounge for Delta Air Lines and provide additional expansion space for the
Port of Seattle common-use Club at SEA lounge. This project is expected to meet existing (pre-
COVID-19) passenger demand for Delta, as they intend to vacate their existing lounge at the
South Satellite. 
To achieve this, Delta desires to design and construct an approximately 47,000 Square Foot (SF)
building expansion at the east side of Concourse A, across from Gate A11 and directly south of
the International Arrivals Facility (IAF), via a TRA with the Port. It is expected that 24,500 SF of
the space will be leased directly by Delta Air Lines for their lounge. 
JUSTIFICATION 
Delta has requested to construct approximately 25,000 square feet to provide additional lounge 
premises to accommodate their passenger demand that is anticipated to shift from the South
Satellite to Concourse A due to the opening of the IAF and the conversion of Concourse A gates
from domestic only operations to gates that are capable of accommodating international
operations.  The Port currently does not have sufficient space to meet this demand. Thus, to 

revised January 10, 2019.

satisfy this request for additional leased space, (which coincides with the Port's Century Agenda
Goal # 2 to advance this region as a leading tourism destination and business gateway) the Port
would either (i) need to build the shell space itself, and then have Delta subsequently design and
construct their own tenant improvements, or (ii) allow Delta to design and construct the building
addition under a TRA. In addition, this proposed expansion will create additional space that will
be useful for future expansion of the Port's common-use lounge on Concourse A, which would
provide needed capacity to support pre-COVID passenger levels, as well as anticipated capacity
that will shift from South Satellite to Concourse A as a result of the completion of the IAF project. 
Proceeding with having Delta design and construct the improvements is likely to both be less
expensive, as well as faster, than the two-step process of the Port constructing the shell, and
then Delta constructing their tenant improvements. 
Diversity in Contracting 
The project team met with the Port's Diversity in Contracting Department and the Tenant
Reimbursement Agreement with Delta will include mutually agreed WMBE aspirational goals. 
DETAILS 
The budget range is based on the 30% design cost estimate provided by Delta for tenant
reimbursable shell and core construction costs. The budget includes Port soft costs, Delta's
design and project management costs for the TRA, art, and project contingency. After the 60%
design and cost estimate and TRA negotiations are completed, staff will return to Commission to
request authorization for construction. 
The project 30% design was completed in March 2020 at Delta Air Lines' risk, with the plan to
request Commission authorization after 90% design and Delta's receipt of contractor bids that
will better inform the maximum cost for the project. When the COVID-19 pandemic drastically
impacted passenger travel, the project was put on hold by Delta. 
Now, Delta is ready to resume design work, provided the Commission authorizes design funding
to reimburse them for design costs under a TRA. At the 60% design milestone, the Port intends
to negotiate a TRA cost split and maximum gross construction price with Delta. Presuming
agreement, staff would then seek additional Commission construction authorization and an
amendment to Delta's TRA for the final reimbursement value. 
Scope of Work 
This expansion includes approximately: 
o  24,500 SF for a new Delta passenger lounge, including 2,300 SF of shell space for
future expansion 
o  7,600 SF of shell space for a future expansion of the neighboring Port of Seattle
common-use lounge 
o  7,200 SF of vertical circulation, including stairs, elevators, mechanical space

Meeting Date: April 27, 2021 
o  7,600 SF of support areas for mechanical, electrical, plumbing and fire protection
systems 
The project also includes: 
o  1,200 SF of reconfigured existing space on the concourse level to accommodate a
new lounge entrance and associated revisions to the adjoining restrooms and
Airport Dining and Retail spaces 
The project (and Delta's current cost estimate) do not currently include scope to account
for two key unknowns that would ultimately increase the scope and final cost of this
project. Both unknowns require Delta to progress their design beyond the current 30%
level, so require this Commission authorization to further define. It is important to
recognize, that if either of them comes to fruition, they will result in an increase in the
final project cost estimate. 
o  The existing Concourse A hot and chilled water piping system might need to be 
expanded by this project to increase capacity. This will be better understood after
field investigation is completed when the design process is restarted, and it might
be added to the project scope. 
o  The  mezzanine  level  of  the  proposed  expansion  may  be  increased  by
approximately 3,000 sf to match the footprint of the Delta lounge space above
with no overhang. This is not currently in the project scope but may be added after
the design process is restarted to ensure the Port receives its desired scope out of
the Delta run project.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do not proceed with this project. 
Cost Implications: $120,000 
Pros: 
(1)   Lowest cost alternative. 
Cons: 
(1)   Fails to satisfy tenant's desired expansion premises. 
(2)   Fails to address deficiency in lounge premises on Concourse A to support flights that
will be accommodated there due to opening of the International Arrivals Facility. 
This is not the recommended alternative. 
Alternative 2  The Port designs and constructs the shell expansion of the building, and then
Delta would subsequently construct their tenant improvements. 
Cost Implications: Higher than alternative 3 (specific amounts not disclosed due to ongoing
negotiations). 
Pros: 
(1)   Port controls the design/construction process. 
(2)   Does not require negotiating a fairly complex TRA agreement with Delta. 
Cons: 
(1)   Process likely to be slower, and more expensive, than Alternative 3 because landlord
work would need to be completed and turned over prior to tenant improvements being
able to be constructed. 
(2)   Requires more Port project management and construction management resources than 
are currently available. 
(3)   Does not take advantage of the Port's TRA policy that allows for a more efficient single
contractor design and construction process. 
This is not the recommended alternative. 
Alternative 3  Allow Delta to design and construct the shell expansion space, as well as their
tenant improvements under a Tenant Reimbursement Agreement between the Port and Delta. 
Cost Implications: $71,400,000 
Pros: 
(1)   Likely to be the lowest cost, and fastest, delivery method for this project. 
(2)   Puts less demand on limited Port project management and construction management
resources. 
(3)   More efficient design and construction process (using a single designer and contractor)
through a TRA, versus both the Port and Delta hiring separate designers and contractors

that would need to coordinate and could end up tearing out some elements of recently
constructed base building facilities. 
Cons: 
(1)   More costly than not constructing the additional space. 
(2)   Requires negotiating a fairly complex TRA agreement with Delta. 
This is the recommended alternative.
