SUBJECT:  Air Cargo 5 (AC-5) Ground Boarding Facility, Additional Funding Ratification to Close-out
the project (CIP #C801089) 
Amount of this request:                  $25,000 
Total estimated project cost:            $575,000 
ACTION REQUESTED 
Request Commission ratification and authorization of the additional expenditure of $25,000
needed to close out the Air Cargo 5 Ground Boarding Facility project at Seattle-Tacoma
International Airport for a total revised authorization of $575,000. 
EXECUTIVE SUMMARY 
This action requests additional funds to complete closeout for a pre-fabricated building with a
restroom and breakroom for 15-20 employees. This project serves two purposes; first to support
mitigation of North Satellite (NSAT) construction impacts to Alaska operations and second to
accommodate increased use of Air Cargo area five (AC-5) hardstand for multiple airline ground
board operations. 
JUSTIFICATION 
The project is complete and operating. An added $25,000 expenditure was necessary for changes
near the end of the project and to close-out the project.  The modest increase was necessary
because of varying site conditions and code compliance discovered during construction. 
DETAILS 
The project was executed as a separate CIP under the umbrella of the NorthSTAR program
managed by the NSAT project management team. The pre-fabricated trailer was procured using a
Port accessible, existing state contract, placed and with utilities tie-in work completed by Port
Construction Services (PCS) with design support from an existing consulting design contract. In
April 2019, the Port initiated a project to install a pre-fabricated trailer at the AC-5 Ground
Boarding Facility. Roles and responsibilities for the project were established as follows:
