TO: Stephen P. Metruck, Executive Director
FROM: Keri Stephens, Director, Aviation Facilities and Capital Programs

SUBJECT: Compactor Capacity Design and Construction Authorization (C801030)
Amount of this request:
$3,900,000
Total requested project cost:
$4,500,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to (1) authorize design and
preparation of construction bid documents; (2) advertise, award, and execute a major works
construction contract; (3) execute related project change orders, amendments, work
authorizations, purchases, contracts, and take other actions necessary to support and deliver the
Compactor Capacity project within the approved budget; and (4) authorize use of Port of Seattle
crews to support the design and construction activities. This request is for $3,900,000 of a total
estimated cost of $4,500,000.
EXECUTIVE SUMMARY
The purpose of this project is to expand capacity and improve sanitary conditions of the airfield
solid waste (garbage, and recycling) infrastructure. Significant passenger growth in the past 15
years has resulted in solid waste volumes that require our solid waste systems to operate at or
near maximum capacity with overages during peak times. The project supports the diversion of
waste from landfills by ensuring throughput capacity is available for recycling. The project
supports solid waste redundancy through providing additional solid waste assets, enabling
operations to continue during peak times and inclement weather.
Solid waste throughput and capacity are essential for airport operations, worker safety, pest
control, and overall sanitation. This project ensures operational integrity of the airfield solid
waste operations by adding four new compactors, two trash and two recycling, at the north end
of the airfield near gate E-100.

JUSTIFICATION
This action ensures adequate airfield solid waste infrastructure is in place to meet operational
needs, pest control, and worker safety requirements. Solid waste generation is directly
proportional to the number of passengers utilizing SEA. Trash and recycling compactor locations
are now experiencing higher volumes than intended and create single points of failure for the
SEA waste management system. Trash and recycling outflow is constrained by infrastructure
limitations. The dispersed trash and recycling compactor locations regularly reach maximum
throughput during peak times and compactors are often full well before haul can be performed.
Limited waste throughput capacity along with unscheduled maintenance events, create safety
hazards, unsanitary conditions, and impede airport operations. This project will reduce the single
point of failure when a compactor is full, being hauled off, or goes out of service for maintenance
by co-locating them to an accessible location. By co-locating the compactors, if one compactor is
not available operators will be able to use the adjacent one and reduce the downtime to dispose
of trash and recycling and increase the throughput capacity. The new location will be accessible
to the ramp operations but removed from the high activity area. Haul off and disposal operations
will not disrupt ramp operations or compactor operations which could lead to delays or no place
to dispose of trash and recycling.
Diversity in Contracting
This project will use an existing Indefinite Delivery, Indefinite Quantity (IDIQ) contract for design
that was established in 2022. The contract includes a 16% women-and-minority-owned business
enterprise (WMBE) participation utilization requirement. The project team will work with
Diversity in Contracting Department to determine participation opportunities and appropriate
aspirational goals for WMBE for the construction phase of the project.
DETAILS
Project site will be developed outside of the airfield fence, and a fence relocation will be
completed to include the project site during construction. The project site is a former fuel farm
that will be repurposed for beneficial use. The compactors will primarily serve airplane waste and
provide redundancy to existing compactor locations.
Scope of Work
(1) Pre-manufactured covered trash compactor structure to accommodate four compactor
units.
(2) Structure will be open air on all sides with a fabric chain-link fence or similar enclosure
to obscure three sides of the structure.
(3) Design of structural pad and foundation to accommodate compactors and pre-
manufactured structure.
(4) AOA fence modification to have the compactor structure located on the secure airside.

(5) Roadway modifications required to provide trash compactor truck access from the
apron to the new structure.
(6) Site utilities to provide, power, communication for cameras and compactors, and
water/sewer to the new structure.
(7) All other work necessary to ensure the site function as intended.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 –Status Quo – Don’t install new compactor location.
Cost Implications: $500,000 spent to date would need to be expensed.
Pros:
(1) Reduces capital expenditure
Cons:
(1) Does not address airfield trash and recycling capacity.
(2) Does not provide safe and updated compactor site location.
(3) Does not address displaced compactors at C1
This is not the recommended alternative.
Alternative 2 – Develop site at E-100 location with CMU block building and add four (two each
recycle and trash) 30 yard compactors, with accompanying infrastructure (power, rails, electronic
access systems) at a location at the north side of the airfield (this includes relocating C1
compactors).
Cost Implications: $5,500,000
Pros:
(1) Prevents leachate, contains foreign object debris (FOD)
(2) Provide uninterrupted disposal capability and eliminate single line of failures at airfield
compactor locations.

(3) Increase overall airport trash and recycling capacity.
Cons:
(1) Highest capital expenditure
This is not the recommended alternative.
Alternative 3 – Develop site at E-100 location with metal enclosed structure and add four (two
each recycle and trash) 30 yard compactors, with accompanying infrastructure (power, rails,
electronic access systems) at a location at the north side of the airfield (this includes relocating
C1 compactors).
Cost Implications: $4,500,000
Pros:
(1) Lowest cost alternative
(2) Prevents leachate, contains FOD
(3) Provide uninterrupted disposal capability and eliminate single line of failures at airfield
compactor locations.
(4) Increase overall airport trash and recycling capacity
Cons:
(1) Requires capital expenditure
This is the recommended alternative.
