EXECUTIVE SUMMARY 
The IAF request is for Commission authorization of the unfunded balance of the previously
agreed project cost plus an increase staff believes sufficient to complete the project. Grant of
this request will permit the IAF team to continue advancing the work while actively negotiating
a roll-up GMP with the design-builder. 
The NSAT request represents the final expected Commission authorization to complete the
expansion and modernization of the 45-year old satellite with the execution of the final
Maximum Allowable Construction Cost amendment to the Hensel Phelps contract and approval
of the other actions listed above. At completion the new facility will support the airports and
regions urgent demand by greatly enhancing travelers' experience and airport operations. 
Refer to attached IAF and NSAT project specific memos, Attachments A and B, respectively. 
JUSTIFICATION 
Sea-Tac is experiencing record growth driven both by one of the fastest growing regional
economies, the draw of the Seattle Tacoma metropolitan area, and by domestic and
international airline service successes. This has resulted in a shortage of aircraft gates and
existing facilities that cannot accommodate the demands of customers and passengers.
Additionally, both the North Satellite and the South Satellite, which houses the existing Federal
Inspection Services (FIS) for processing arriving international passengers, were constructed in
the early 1970's and have not had any significant renovations made since their opening. These
facilities are in desperate need of modernization and expansion to respond to airport-wide
growth, and to provide world class facilities for our customers and passengers. To sustain Sea-
Tac's competitive advantage and succeed within the national market place for airports, as laid
out in the Century Agenda, the airport must modernize and expand its aging facilities. The IAF
and NSAT projects are critical to achieving this. 
This request allows these two critical projects to proceed to completion and to respond to the
fast changing dynamics of the airport, meet the needs of multiple airlines and make a
deliberate and significant step to improving Sea-Tac's capacity, customer level of service and
competitive ranking among peer airports. Specific details, requirements, and supporting
information for the requested actions are presented in Attachment A for the IAF project and
Attachment B for the NSAT project.
