TO: Stephen P. Metruck, Executive Director
FROM: Cox, Sarah, Director, Aviation Environmental
Francisco, Eileen, Director, Aviation Project Management
SUBJECT: Electric Vehicle Chargers for the Aviation Fleet Design and Construction
Authorization (C801232)
Amount of this request:
$2,698,000
Total estimated project cost:
$2,947,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to (1) authorize design and prepare
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 Electric Vehicle
(EV) Chargers for Aviation Fleet project within the approved budget; and (4) authorize use of Port
of Seattle crews and small and major works on-call contracts to support the design and
construction activities. This request is for $2,698,000 of a total estimated cost of $2,947,000.
EXECUTIVE SUMMARY
The Aviation Fleet Manager is working to transition Seattle-Tacoma International Airport’s (SEA)
vehicle fleet to electric per the Port’s Sustainable Fleet Plan. This project supports that effort by
installing 15 Level 2 chargers at fleet parking spots on the first floor of the Parking Garage, and a
mix of Level 2 and Level 3 chargers for 7 spots on the airfield near Concourse D. By enabling the
conversion of these high-use vehicles to electric, the Aviation Division can reduce both
greenhouse gas emissions and total lifetime cost to own and operate vehicles in comparison with
internal combustion engine vehicles.
JUSTIFICATION
This project will support the electrification of high-use Aviation fleet vehicles. The Level 3
chargers on Concourse D will allow Aviation Operations to use electric trucks for a range of tasks
across SEA locations. These Level 3 chargers will be able to charge vehicles in 1-2 hours,
dramatically reducing charging time when compared to the Level 2 chargers that take 8-10 hours.

Meeting Date: May 28, 2024

The Level 3 chargers are needed on the airfield as these vehicles are used continuously, especially
during emergency response situations and snow events. Chargers in the Parking Garage are
planned to be Level 2 as the vehicles that will use these chargers have more regular downtime
and can charge overnight or between shifts.
This project will reduce greenhouse gas emissions of the Aviation fleet by at least 175 metric tons
of CO
2
per year. This is nearly 20% of the current annual CO
2
emissions from the Aviation fleet.
This will help the Port meet its Century Agenda goal to reduce greenhouse gases by 50% by 2030.
Electrifying the vehicle to be supported by these chargers will also save at least $85,000 per year
in fuel costs.
Diversity in Contracting
This project will use an existing 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 is installing 15 Level 2 chargers in the Parking Garage; and a mix of Level 2 and Level 3
chargers on Concourse D to support 7 parking spots. These chargers will support electric charging
for at least 22 high-use fleet vehicles.
Scope of Work
Work involves installing the infrastructure required to support the new EV chargers. This will
include:
(1) Electrical power and conduit from electrical panels to charging equipment;
(2) Signage as required by code;
(3) Striping for parking stalls and as needed for movement of drive lanes;
(4) Bollards to protect the charging equipment;
(5) Foundations for charging pedestals;
(6) Charging equipment; and
(7) All other necessary work to ensure the chargers work as intended.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Status Quo – Don’t install the EV Chargers
Cost Implications: Expense $240,000 spent to date
Pros:
(1) Reduces the capital expenditure
Cons:
(1) Does not allow for electrification of high-use vehicles on the ramp of the Airport
(2) Requires expensing the cost of work to date
This is not the recommended alternative.
Alternative 2 – Install only the chargers on the ramp of Concourse D to support 7 parking spots.
Cost Implications: $1,874,000
Pros:
(1) Reduces the capital expenditure
(2) Allows for electrification of 7 high-use vehicles on the ramp of the Airport
Cons:
(1) Does not allow for electrification of 15 high-use vehicles in the Aviation Fleet
This is not the recommended alternative.
Alternative 3 – Install 15 chargers on in the fleet area of the Parking Garage and chargers on
Concourse D for 7 parking spots to support electrification of high-use vehicles.
Cost Implications: $2,947,000
Pros:
(1) Supports electrification of 22 high-use Aviation fleet vehicles
(2) Reduces greenhouse gas emissions by an estimated 175 tons of CO2 per year
Cons:
(1) Highest capital expenditure
This is the recommended alternative.
