SUBJECT: 2027 Airfield Projects (CIP # C801379)
Amount of this request:
$40,000,000
Total estimated project cost:
$400,000,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to take all steps necessary to
complete two construction contracts for 2027 Airfield Projects and limited utility installation
scope on behalf of the S Concourse Evolution (SCE) Program located at the Cargo 7 hardstand
area.
The total amount of this authorization request is $40,000,000.
EXECUTIVE SUMMARY
These two construction contracts are comprised of two interdependent Capital Improvement
Projects (CIPs). Construction Contract #1 encompasses federally funded pavement and utility
infrastructure scope while Construction Contract #2 consists of all other airfield project work in
2027 and SCE power and communication utility installation scope at the Cargo 7 hardstand area.
Funding for the Cargo 7 utility scope was included in the Commission Authorization on August
11th, 2026, for design and construction under SCE CIP C801203. Due to overlapping design
functionality, interdependent operational impacts, and shared 2027 schedule milestones, the
Cargo 7 utility scope as part of the SCE Program was designed and phased to be delivered
concurrently with the Airfield Program scopes for purposes of Airfield safety, efficiency, and
minimization of operational impacts.

2026-2030 Airfield Program (C801379) receive federal grant funding for eligible items meeting
Federal Aviation Administration (FAA) standards with an anticipated FAA grant reimbursement
of $10.96M for the year 2027 and a total of approximately $56M expected for the life of the
program.
JUSTIFICATION
The 2027 Airfield scope is part of the 2026-2030 Airfield Program, which is a continuation of a
programmatic approach for airfield infrastructure renewal and replacement scope needed to
keep the airfield within regulatory compliance. The overarching goal of the Program is to provide
safe and efficient conditions for aircraft operations at SEA and to meet FAA and other regulatory
requirements.
Diversity in Contracting
The project staff, in coordination with the Diversity in Contracting Department, have set goals for
both contracts. However, Airfield Contract #1 is federally funded work and due to the Federal
adjustments to their Disadvantaged Business Enterprises (DBE) program, this goal will be TBD.
Contract #2 is not federally funded and as such will include a 10% Woman and Minority Business
Enterprise (WMBE) aspirational goal. These goals are based upon the projects’ scopes of work,
and baseline availability of certified DBE and WMBE businesses to perform the work under the
two separate contracts.
DETAILS
These projects will interface with other projects and airline operations. Continual coordination
with Airport Operations, Airlines, and related Tenants will ensure the least possible operational
impact during construction.
A project labor agreement will be used for these projects based on the importance of labor
continuity and the need to minimize any risk of impact to operations during construction.

2027 Airfield Contract #1 does not replace or add additional concrete. 2027 Airfield Contract #2
has limited pavement scope for individual concrete panels. For awareness, SEA's concrete meets
FAA design standards and exceeds industry standards for solar reflectivity minimizing heat island
effect. We also conduct routine maintenance including sweeping and runway rubber removal
that maintains solar reflectivity.
Scope of Work
The 2027 project scope includes replacement of distressed pavement at TW B, Taxilane W, Apron
and Cargo areas; replacement of aging and failing airfield utilities located within the Runway
Safety Area (RSA) for RW16R/34L; replacement of failing non-standard flush fire hydrant access
hatches; renewal and replacement of electrical circuits with low megger readings and installation
of LED lighting fixtures and signs for RW16R/34L and connecting taxiways; removal of turf edge
dams along RW16R/34L, connecting taxiways and access roads; mitigation of water ponding
areas and installation of anti-perching devices within the RW16R/34L RSA.
The 2027 Contract #2 will also construct utility installation scope at Cargo 7 as a facilitating
project on behalf of the SCE program.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Proceed only with federally funded 2027 Contract #1 Airfield work including the
replacement of aging and failing airfield utilities, non-standard flush fire hydrant access hatches,
electrical circuits, lighting fixtures and signs; removal of turf edge dams; mitigation of ponding
spots and installation of anti-perching devices at RW 16R/34L, connecting taxiways, infield areas
and vehicle service road. Do not proceed with the scope in 2027 Contract #2 including
replacement of distressed pavement at TW B, Taxilane W, Apron and Cargo areas, and installation
of power and communication at Cargo 7 area.
Cost Implications: $33M in Cost for 2027 Contract #1.
Pros:
(1) Reduced capital spending in 2027.
COMMISSION AGENDA – Action Item No. 8f Page 4 of 6
Meeting Date: October 13, 2026
Template revised June 27, 2019 (Diversity in Contracting).
(2) Less construction impacts to airport operations in 2027.
(3) Grant funded renewal and replacement work will proceed.
(4) Less complexity for budget tracking during construction.
(5) In alignment with FAA’s 5-year ACIP and receive grants.
Cons:
(1) Safety risks associated with failing airfield pavement and supporting infrastructure
included in 2027 Contract #2 are not addressed.
(2) Alternative is not in alignment with the current Port Century Agenda Goals. Aviation
Asset Management Goal: To deliver world-class SEA infrastructure and
Achieve 99% uptime for all critical assets by minimizing downtime across all CIP projects
to enhance operational reliability. Develop Sustainable and Resilient Facilities and
Infrastructure.
(3) Increased cost in the future due to escalation.
(4) Operational impacts from emergency repair/replacement.
This is not the recommended alternative.
Alternative 2 – Move forward with full scope proposed for 2027
Cost Implications: $40M in Cost for 2027 Contract #1 & Contract #2.
Pros:
(1) Provides safe and efficient conditions for aircraft operations and meets Federal
Aviation Regulations and other regulatory requirements.
(2) Programmatic replacement of aged and distressed pavements and related
infrastructures.
(3) In alignment with FAA’s 5-year ACIP and receive grant.
(4) Reduces safety risks, minimizes operational impacts and increases efficiencies as
coordination and construction is managed as combined construction contracts.
(5) Reduces maintenance costs by investing in renewal of critical assets.
(6) Meets Port goals.
Cons:
(1) Large capital costs in 2027.
(2) Increase complexity for budget tracking during construction.
(3) Operational impacts during construction.
This is the recommended alternative.

Annual Budget Status and Source of Funds
2026-2030 Airfield program was included in the 2026-2030 capital budget and plan of finance.
Project C801379 - 2026-2030 Airfield program anticipates approximately $56M in Federal
Aviation Administration (FAA) entitlement funds with the opportunity to receive additional
discretionary funds. The funding sources will be the Airport Development Fund, FAA grants, and
revenue bonds. This project is subject to the Port’s Very Large Project Process per Signatory Lease
Operating Agreement (SLOA) V.
Financial Analysis and Summary
Project cost for analysis
$400,000,000
Business Unit (BU)
Airfield movement and Airfield apron
Effect on business performance
(NOI after depreciation)
NOI after depreciation will increase due to inclusion of
capital (and operating) costs in airline rate base.

CPE Impact
Total project cost CPE of $1.06 in 2031; annual CPE of

Future Revenues and Expenses (Total cost of ownership)
This program will reduce the amount of time currently spent by the Port Maintenance team on
joint seal and pavement spall repairs. The new pavement will have a 40-year asset life and a
greatly reduced risk of loose gravel and rock Foreign Object Debris (“FOD”) that could be picked
up by vehicle tires or blown by jet engine exhaust and spread across the apron, taxiways and
runways.
The recircuiting scope will cause a decrease in annual operating & maintenance costs. This is
because the project will install more resilient LED lighting and signs, which is easier to maintain
as it has a longer life than the current incandescent lighting and signs. Furthermore, PVC conduit
will be installed, which makes cable pulling easier.
