FROM:    Michael Ehl, Director, Aviation Operations 
Wayne Grotheer, Director, Aviation Project Management Group 
SUBJECT:  Exterior Gate Improvements  Airline Realignment (CIP # C800472) 
Amount of This Request: $499,000      Source of Funds: Airport Development Fund 
and/or existing bond proceeds 
State and Local Taxes Paid: $0           Total Project Cost: $2,650,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to authorize design of the
Exterior Gate Improvements  Airline Realignment in the amount of 499,000 at Seattle-Tacoma
International Airport (Airport). This authorization is for $499,000 out of a total project estimated
cost of $2,650,000. 
SYNOPSIS: 
This authorization is one of many that have already been approved by the airlines and is 
necessary for the one-time realignment of air carrier operations that will take place at the Airport
over the next few years. The realignment was driven by the merger of two different sets of
major carriers and the consolidation needs for Alaska Airlines which necessitated the
repositioning of gating, holdroom, and ticketing positions throughout the Airport. The air
carriers are pursuing an aggressive schedule in which we complete the first relocation this year,
followed by four (4) airline relocations in 2012, and three (3) additional relocations in 2013 prior
to Alaska Air Group's renovation of the North Satellite and Concourse C. The total estimated
capital costs for the realignment program is $30-$35 million. The associated tenant relocation
reimbursements and expense costs are estimated at $20-$25 million. In addition, there are a
series of linked projects estimated at $70 million. See Attachment A for a listing of the projects. 
Due to this realignment, a number of airlines are scheduled to relocate aircraft gate operations.
Aircraft gate parking positions must be reconfigured to support these new operations. This will
require new exterior gate improvements including new aircraft fueling pits and new aircraft

docking guidance systems. These improvements will enable these airlines to maintain similar
operations at their new gate locations as at their current locations. Design will be accomplished
in-house by the Port of Seattle Engineering Department.
BACKGROUND: 
With on-going airline consolidation interests and a goal to maximize utilization of our existing
facilities, the Airport has issued intent to exercise the One-Time Reallocation provision in the
current Signatory Lease & Operating Agreement (SLOA). The reallocation will require a
number of modifications associated with the airlines that will relocate their gates and ticket
counter operations, to effectively operate in their new locations. It is the intent that a relocated
airline will be functionally equal in its new location, compared to its existing operation. 
PROJECT JUSTIFICATION: 
As airlines relocate gate operations on Concourses A, B and D, many of the aircraft parking
positions on the ramp must be adjusted due to differences in aircraft size/type. When this occurs, 
certain fuel pits will be out of alignment with the new aircraft parking positions. Installing new
fuel pits allows the aircraft to be fueled using the hydrant system rather than fuel trucks,
maintaining the increased ramp safety achieved when the hydrant system was installed and
minimizing fuel truck emissions.
American Airlines currently utilizes an automated aircraft docking system (Safedock) on gates
from which they operate on Concourse A. They have requested that this system be provided at
their relocated gates on Concourse D. Automated docking systems allow for free flow to the
gate and detect if a parking position is blocked between the docking system and the expected
nose position of the aircraft. This improves efficiency and ramp safety, reflecting cost savings to
the airlines.
PROJECT STATEMENT AND OBJECTIVES: 
Project Statement: 
Install new fuel pits at selected gates on Concourses A, B, and D. Install three (3) new Safedock
aircraft docking systems on Concourse D. 
Project Objectives: 
As airlines are relocated, this project will improve utilization of Airport facilities with the least
amount of disturbance giving the Airport the optimum flexibility for aircraft parking.

PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
Construct new fuel pits to accommodate revised aircraft gate layouts on Concourses A, B, and D. 
Fuel pits must be located to align with the projected aircraft fleet mix for each gate. Install new
Safedock aircraft docking systems at three gates on Concourse D to accommodate the move of
American Airlines.

ECONOMIC IMPACTS AND BUSINESS PLAN OBJECTIVES: 
A number of airlines are projected to relocate operations. This will result in airline relocations to
different gates. This project will make necessary modifications to the gates to accommodate the
airline moves. Failure to make these proposed changes could negatively impact airline
operations and customer relations. 
STRATEGIC OBJECTIVES: 
The Exterior Gate Improvements supports two of the Port's Strategies and Objectives, notably: 
This project promotes the Port's strategic goals to "Ensure Airport and Seaport Vitality" and "Be
a Catalyst for Regional Transportation Solutions" by providing the airlines with the facilities and 
equipment to maintain performance. With numerous airlines relocating to other gate and ticket
counter locations, there are modifications that must be addressed for the airlines to effectively
operate in their new locations. The relocations will yield a more balanced facility, increasing 
through-put rates in a finite sized terminal. There are a number of projects, which are directly
tied to this One-Time Reallocation (Airline Realignments) program, that are in concert with
Alaska Air Group's Master Plan to consolidate their gate operations onto the North Satellite and
Concourse C.

TRIPLE BOTTOM LINE SUMMARY: 
This project will increase the long-term ability of the Airport to serve a growing number of
passengers and airlines. Long-term vitality of the Airport benefits the regional economy, the
local environment, and nearby communities. 
ALTERNATIVES CONSIDERED/RECOMMENDED ACTION: 
ALTERNATIVE 1: Have the Port install new fuel pits and new Safedock aircraft docking 
system as described to facilitate airline relocations and provide for the best utilization of airport
gate resources. This alternative minimizes costs by completing work through a single entity.
This is the recommended action. 
ALTERNATIVE 2: Require individual airlines to install new fuel pits and new Safedock aircraft
docking system in their leased gates and have the Port install new fuel pits in common use gates.
This alternative would increase costs by completing work through multiple entities. This is not
the recommended action. 
ALTERNATIVE 3: Do nothing. This alternative would complicate the realignment program by
limiting the kind of aircraft that can be parked and fueled efficiently at the subject gates. It
would require additional fuel trucks on the ramp thereby increasing traffic and congestion,
posing increased safety risks. This is not the recommended action.
