SUBJECT:   Airline Realignment Miscellaneous Building Improvements-Airline Realignment
(CIP #C800475) 
Amount of This Request: $0            Source of Funds: Airport Development Fund 
Est. State and Local Taxes: $94,000      Est. Jobs Created: 15 
Est. Total Project Cost:     2,722,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to (1) reduce the scope of the
Miscellaneous Building Improvements project that is part of the Airline Realignment program at
Seattle-Tacoma International Airport; (2) execute a contract estimated at $220,000 for purchase
of equipment; and (3) use Port crews for project construction. No additional funding is requested
with this authorization. 
SYNOPSIS: 
The work planned under this authorization represents the next phase in a time-critical sequence
supporting the broader airline realignment effort while also providing improved operational
flexibility and efficiency at the Airport. 
This project is part of the one-time realignment of air carrier operations that will occur in 2013. 
This authorization is necessary due to a change in scope since the December 6, 2011, 
authorization.  Concourse A is not currently equipped to provide accessible passenger loading
onto the small regional aircraft of United Express and Air Canada/Jazz, so a new exterior
covered passenger ramp will be needed at that location. During the design process, the planned
gate assignment for the United Airlines regional aircraft was changed from Gates A13/14 to Gate
A6. Additionally, the scope was reduced from a fully enclosed architectural ramp, stairs, or
elevator to a pre-fabricated covered ramp to be assembled on-site by Port crews and small works
contractors. The contract to purchase pre-fabricated covered ramp equipment is estimated to be
approximately $220,000. These scope changes were made in order to reduce construction costs
for the project, and the changes are supported by United Airlines. The project also includes other
miscellaneous capital improvements that are part of the airline realignment program. This project
was included in the 2013  2017 capital budget and plan of finance. Authorization in the amount
of $1,721,000 was previously granted for the project and no additional funding is being

requested at this time.  As a result of the change in scope, the total project budget has been
reduced by $5.2 million. 
BACKGROUND: 
With ongoing airline consolidation interests and a goal to maximize utilization of existing
facilities, the Airport is exercising the One-Time Reallocation provision in the current Signatory
Lease & Operating Agreement.  The reallocation will require a number of modifications
associated with the airlines that  will relocate their gate and ticket counter operations, to
effectively operate in their new locations. 
This  project  includes  other  miscellaneous  capital  improvements  in  the  Airport  terminal 
associated with Airline Realignment. At present that includes upgrades to the air ventilation
ductwork for the new ticket offices for three relocated airlines. 
PROJECT JUSTIFICATION: 
Project Objectives: 
Accommodate the airline relocations by providing miscellaneous building improvements
throughout the Airport terminal. 
Provide accessible boarding between the concourse level and the regional aircraft ground
boarding at Gate A6. 
Provide safer access to the ground level by providing a weatherprotected, sloped
walkway. 
Improve customer service and safety by providing new vertical circulation between the
concourse and ground level for access to/from regional aircraft. 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
This project will provide an exterior passenger boarding ramp that is compliant with the
Americans with Disabilities Act (ADA) at Gate A6 on Concourse A as part of the Airline
Realignment program.

Budget Status and Source of Funds: 
This project is included in the 2013-2017 Capital Budget and Plan of Finance within CIP
#C800475, Miscellaneous Building Improvements-Airline Realignment.   The budget was
decreased due to a combination of transfer of budget and authorization for the relocation of
Virgin America's ticket counter and office,to the Convert Ticket Zone 3 Flow Thru (CIP
#C800492) project,  and to recognize anticipated cost savings. The funding source will be the
Airport Development Fund.

CPE Impact                   CPE will increase by $.01 in 2014, but no change to

Lifecycle Cost and Savings: 
There will be a minor increase in staff costs to maintain the ramp equipment and new access
control card reader at the ramp, but the annual operating and maintenance costs are not
forecasted to change appreciably. 
STRATEGIC OBJECTIVES: 
The project supports  the Port's Century Agenda objective of meeting the region's air
transportation needs at Sea-Tac Airport for the next 25 years, by providing flexibility of the
existing airport facilities. It  supports  the airline realignment program, which benefits our
passengers and airline partners. 
ENVIRONMENTAL SUSTAINABILITY: 
This project demonstrates environmental sustainability by improving existing Port assets and
better utilizing  existing  resources.  Realignment  will  allow more  effective  use of  terminal
facilities, and this enables efficient operation for airlines at new locations. More sustainable
operations  of  the  Airport  are  expected  to  generate  lower  lifecycle  costs  of  the  needed
investments. 
BUSINESS PLAN OBJECTIVES: 
The Airport business plan notes that a strategic goal is to operate a world-class international
airport by meeting the needs of our tenants, passengers, and the region's economy. This project
facilitates airline relocations to different gates and ticket counters and meets the needs of our
tenants, passengers, and the region's economy. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1 (Do nothing): This alternative would preclude the realignment program as jointly
recommended by the Airline Airport Affairs Committee and the Aviation Division. This
alternative is not recommended.

COMMISSION AGENDA

Alternative 2: Provide a custom-designed, fully-enclosed architectural ramp or elevator. This
alternative would cost significantly more and would limit flexibility for future aircraft gate
assignments. This alternative is not recommended. 
Alternative 3: Provide miscellaneous building improvements at the Airport terminal to support
the airline realignment program. Work consists of a pre-fabricated passenger accessible loading
ramp to board planes at Gate A6 and other miscellaneous capital improvements. This is the
recommended alternative. 
OTHER DOCUMENTS ASSOCIATED WITH THIS REQUEST: 
None.
