SUBJECT: Post IAF Airline Realignment Enabling Work Construction Authorization
(CIP #C801158)
Amount of this request:
$14.4 million
Total estimated project cost:
$102 $140 million
ACTION REQUESTED
Request Commission authorization for the Executive Director to (1) authorize enabling
construction work for the Post IAF Airline Realignment project at Seattle-Tacoma International
Airport, (2) procure long lead items, (3) increase the project authorization by $14,400,000, and
(4) execute a project labor agreement. The range of the total estimated cost of this project is
$102 million to $140 million.
EXECUTIVE SUMMARY
The project is facilitating the relocation of United Airlines’ (UA) domestic only operations from
Concourse A to Concourse B. This allows for airlines with international flights to use the vacated
international capable gates on Concourse A. Associated office and support spaces to support
both relocations, a ticket counter reconfiguration in the main terminal and United Airlines Lounge
renovation on Concourse B will be delivered as part of the project. This request is to authorize
funding for the construction of enabling work, facilitating initial existing infrastructure
relocations, and building code upgrades necessary to initiate the base program work.
As briefed on September 12, this project has four main packages of work being completed by the
Port, beginning with a package of enabling work and three packages of base program work. The
enabling work addresses code deficiencies, completes initial existing utility and infrastructure
relocations and includes demolition and reconfiguration at the ramp level of the A, B and S
Concourses. The enabling work delivers approximately 14,900 square feet of renovated Port and
tenant leasable space. The project team will return in December 2023 to request construction

authorization for the remaining 47,500 square feet of base program work included in the
remaining packages.
The amount of this request is $14,400,000 for enabling work construction. The current cost
estimate range for the full program is $102 - $140 million.
JUSTIFICATION
Construction authorization for the enabling work is required to make way for base program work
and support the Port’s overall airline realignment project progress and future gate allocation by
advancing the relocation of airlines as planned.
Significant phasing and sequencing are required to provide the spaces necessary to deliver the
base program scope. Initiating key infrastructure and existing systems relocations on Concourse
B ramp through the enabling work allows the GCCM to streamline construction durations and
avoid periods of time where no work is performed.
This program supports the Port’s Century Agenda’s strategic goal of “Advancing this region as a
leading tourism destination and business gateway” by:
(1) Continuously improving operational efficiency and customer experience at the Airport.
(2) Strengthening the competitiveness of the Airport in the regional and global marketplace.
(3) Meeting the region’s air transportation needs by delivering vital facilities and
infrastructure in sustainable and cost-effective manner.

has informed the design and supported the acceleration of key areas of enabling work that are
captured in this first construction authorization.
The design for the base program scope of work for the project has progressed through 60%
development. The project team will return to the Commission in December when the design has
been progressed through 90% and the full construction cost determined through public
procurement.
To execute the program, the project team intends to inform and request the necessary
authorizations according to the schedule below:

December 2023Base Program Construction Authorization
December 2023United Lounge Briefing
Quarter 2 2024 United Lounge Construction Authorization
The airline realignment construction work is currently broken down into two distinct phases.
Enabling Work
(1) Renovations to existing Port-occupied and tenant-leased spaces on Concourse A and
South Satellite ramp level to support tenant relocations required for the airline
realignment.
(2) Code upgrades and modifications to existing building systems and infrastructure to
support the future base program work on Concourse B ramp.
(3) Renovation, consolidation, and code upgrades to existing Port mechanical and electrical
spaces on Concourse B ramp, including dedicated rooms and security access control
upgrades to meet Port standards.
(4) Renovation of existing tenant-leased space on Concourse B ramp to consolidate existing
airline operations and allow for construction of a new interior corridor.
(5) New airline tenant cage storage on Concourse B ramp.
(6) Renovated and expanded restroom facilities to address code deficiencies on Concourse B
ramp.
(7) Procurement of mechanical upgrade equipment that has a manufacture and delivery
duration of several months to mitigate the impact to the construction schedule. These
include Air Handling Unit 2 and Air Handling Unit 4.
COMMISSION AGENDA Action Item No. 8d Page 4 of 8
Meeting Date: September 26, 2023
Template revised June 27, 2019 (Diversity in Contracting).
Base Program
(1) Renovations to existing tenant-leased spaces on Concourse A to support final tenant
relocations required for airline realignment.
(2) Renovated and expanded tenant-leased spaces on Concourse B ramp to create new office
support space for the relocated airline tenant.
(3) Code upgrades to extend the new interior corridor initiated with the enabling work.
(4) Cage storage provided with enabling work will be reconfigured to support final airline
relocations.
(5) Modifications and upgrades to existing Concourse B mechanical system to support the
newly expanded and renovated ramp leasable space, including two new enclosed
penthouses at the roof level.
(6) Renovated ticket counter and tenant-leased space in the central main terminal to provide
ten ticketing positions, an airline break room and Port leasable space for a future tenant.
This division of the scope is advantageous because it:
(1) Allows the project team to begin construction on enabling work that must be completed
to make way for the airline realignment renovation and building expansion.
(2) Value-added leasable space is improved while facilitating a coordinated consolidation of
Delta airlines Concourse B ramp support space. This consolidation makes available the
necessary leasable square footage to deliver like-for-like ramp support spaces for United
Airlines to relocate gate operations from Concourse A to Concourse B.
The project team will continue to gain budget and schedule certainty as the design progresses
through 90% development and the construction is publicly procured in Q4 2023.
Schedule
To facilitate the complex phased delivery of the project, a portion of work was identified, and the
design accelerated to allow the contractor to begin initial work as the base program design
continued development. The base program work will begin in Quarter 1 2024, after the first
phase of enabling work has been completed and makes the space available.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternatives Considered:
Alternative 1 Delay the procurement and construction of enabling work and combine with final
airline realignment design documents procured in Q4 2023.
Cost Implications: ~$1 million increase to the overall project budget.
Pros:
(1) Delays capital and expense investment for 3-5 months, allowing for a single construction
authorization for all airline realignment work.
(2) Potentially allows for improved cost certainty.
(3) Combining procurement packages into larger, more desirable, scopes of work to increase
the subcontractor participation.
Cons:
(1) Does not allow the project team to mitigate schedule delays through identification of
unforeseen conditions that would be identified during the enabling work.
(2) Delays United Airlines Gate allocation on Concourse B in September 2025
(3) Delays the GCCM from beginning work in tenant lease spaces that are available for
construction now.
(4) Costs will continue to escalate.
(5) Delaying the work could create unforeseen schedule impacts from adjacent Port projects
performing work in 2024.
(6) Significantly reduces the advantages of the GCCM contracting method by delaying the
work the mechanical and electrical subcontractors could negotiate and perform now.
This is not the recommended alternative.
