ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to (1) advertise and execute a
single construction contract comprised of Cargo 2 Hardstand Expansion (CIP #C800247), Cargo
5 Hardstand Construction (CIP #C800254), Cargo 6 HardstandImprovements (CIP #C800390), 
and Airfield Pavement Replacement-Cargo 6 Apron (CIP #C102583); (2) execute contracts for
400 Hz ground power units, fire extinguishers, and furniture; and (3) to authorize port crews to
perform advance work associated with project delivery. This authorization is for $50,607,383,
and the cost for the complete project is $69,258,000. 
SYNOPSIS 
The combined projects ("project") will promote air freight and regional economic vitality by
allowing large freighter aircraft to operate efficiently at Cargo 2 and 6 hardstands and provide
additional remain-over-night (RON) parking positions at Cargo 5 that are critical to meeting
capacity demand  and  operational efficiency and safety requirements at Seattle-Tacoma
International Airport (Airport). Replacement of distressed pavement at Cargo 6 will also occur

in support of meeting these needs. The  project is consistent with,  and necessary for, 
implementation of the Commission's Century Agendaair cargo goal that calls for tripling air
cargo volume over 25 years. Meeting the goal will require expanded and more efficient facilities.
The Cargo 5 hardstand supports the Port's Century Agenda strategy to meet the region's air
transportation needs at the Airport for the next 25 years. 
Each of the cargo and other hardstand areas include electrical ground-power units that eliminate
the need for aircraft to use their auxiliary power. The underground fuel hydrant system is being
extended to Cargo 6. These features will assist the Port in its commitment to reduce the emission
of greenhouse gasses and other pollutants. A new security access facility at Cargo 5 and a
replacement guard shelter at Cargo 2 are also included in the project. 
These individual projects have been combined into a single construction contract because of the
similarity, proximity, and the timing of the work in each cargo area. The combined projects
benefit from a more efficient design, economies of scale, and lower administrative costs. The
Port will procure some items directly to include 400 Hz ground power units, fire extinguishers 
specific to hardstand use, and building interior furnishings for two airfield security gates
constructed by the project. The Port may also self-perform some elements of work such as the
repair of traffic control items located along the temporary haul route and other small works
projects that may be needed to facilitate overall delivery. Given the size and the security and
schedule constraints of these projects, they are not well suited for small businesses to be prime
contractors, even as separate procurements. The project team will coordinate with the Office of
Social Responsibility to evaluate appropriate small business subcontracting opportunities on the
major construction contract. 
BACKGROUND 
The overall air cargo market is forecast to grow at an annual rate of more than five percent over
the next 20 years, according to Boeing's current World Air Cargo Forecast, driven primarily by
growth in international traffic. The existing Cargo 2 and Cargo 6 hardstands are of insufficient
depth to accommodate simultaneous straight-in parking for large freighter nose-load operations 
common to international freighter use. This project will provide additional concrete apron space
that will provide better maneuverability, increased operational area for all users and will allow
the best utilization of these facilities. 
The Commission has previously approved a lease buyout of one of several ProLogis leaseholds,
which included two buildings, one of which will be demolished to accommodate the expanded
hardstand at Cargo 2. The Port has coordinated with ProLogis regarding the relocation oftheir 
tenants prior to the start of project construction. 
The demolition of the Cargo 2 building also requires the relocation of FAA Airport Surface
Detection Equipment Model-X Remote Unit No. 7 (ASDE-X RU7). The Commission has
previously authorized the execution of an agreement with the FAA and funds for this relocation. 
Additionally, as part of the multi-year concrete pavement replacement project, Port staff has 
specifically identified the Cargo 6 Hardstand area as a location with one of the highest

concentrations of distressed panels at the Airport. The replacement of these panels is included in
the project for efficiency and to reduce operational impacts if replacement were to occur
separately. 
The Airport's geographic location has traditionally been a determining factor in the
accommodation of RON aircraft by airline operators. By virtue of being located in the northwest
corner of the continental United States, a high number of departures are scheduled by the airlines
to leave early in the morning in order to reach their connections and destinations at desirable
times. Many of the morning departure aircraft return to the Airport at night to fuel and prepare
for the next day's early morning flight. As a result of the high number of morning departures,
more passenger aircraft remain overnight at the Airport than there are terminal gates available.
In the absence of sufficient RON parking capacity, airlines will most likely not schedule
additional morning departures. Without sufficient available RON hardstands, the Airport cannot
meet the demands of the airline customers. To accommodate anticipated future growth in RON
demand within the very limited space available, the Airport must convert underutilized airfield
assets to the highest and best use. 
The continuing growth of Alaska Airlines and Delta Air Lines, as well as the potential merger of
American Airlines and U.S. Airways further contributes to a corresponding demand in remainover-night
parking.  Finally, construction phasing for the NorthSTAR project and new
International Arrivals Facility project will ultimately impact existing RON availability over the
next five years. 
The Cargo 5 RON hardstand is being accomplished in three phases. The first phase was the
termination of the lease with the USPS. The second phase was the demolition of the USPS
building, completed in summer of 2012. The third and final phase is the design and construction
of the hardstand. 
Changes to the Airport Operations Area (AOA) Security access points are also necessitated by
the project. Vehicles currently entering the existing Gate E-100 are immediately introduced onto
the aircraft taxilane, which can create conflicts. This gate also has a steep entrance that can limit
access during inclement weather. The new Gate E -125 on the north side of Cargo 5 will provide
better access and eliminate the current potential conflict between vehicles accessing the airfield
and aircraft. At Cargo 2, the current Gate E-185 will be replaced with a relocated Gate E-190 to
accommodate the enlarged hardstand. 
The Commission previously authorized execution of a Project Labor Agreement for the Project. 
PROJECT JUSTIFICATION AND DETAILS 
This project is dedicated to improving efficiency in the use and utilization of off-gate ramp
space, meeting the demands of our airline customers, upgrading and improving airfield access
and security, and proactively reducing the emission of greenhouse gasses and other pollutants. 
Project Objectives: 
Expand the Cargo 2-West hardstand in order to accommodate the increased size and
frequency of wide body cargo aircraft at the Airport

STRATEGIES AND OBJECTIVES 
This project supports the Port's Century Agenda of tripling air cargo volume over 25 years. 
Providing and maintaining critical airfield assets also supports the Port's Century Agenda
objective to meet the region's air transportation needs at Sea-Tac. Modern and efficient air cargo
facilities are fundamental to the creation of an international logistics hub.  Secure access points
to the airfield that operate in all weather conditions and minimize potential conflicts with aircraft
is a safety objective. Ground power and the extension of the fuel system will assist the Port in
reducing greenhouse gas emissions. 
TRIPLE BOTTOM LINE 
Economic Development 
Users of the overall Cargo areas have increased their frequency of operation by more than 50%
in the last 5 years. The overall air cargo market is forecast to grow at an annual rate of more than
5% over the next 20 years, according to Boeing's current World Air Cargo Forecast, driven
primarily by growth in international traffic. Air cargo generally represents more than 30% of the
value of goods exported from the United States and is an essential part of regional economic
vitality and the efforts to increase overall exports. Expansion of the cargo hardstands and the
addition of efficiency upgrades will speed aircraft ground operations, reduce the amount of time
aircraft are on the ramp and will allow aircraft to utilize the area with a higher turnover rate, all
of which increase the Airport's competitiveness for air cargo business. Increased usage equates
to increased exports and increased cargo revenues. 
Replacement of cracked and deteriorated concrete reduces chances of loose and or broken
concrete, which becomes Foreign Object Debris (FOD). If FOD is ingested into an aircraft
engine, it has the potential to cause substantial damage costing millions of dollars in repairs.
Sealing joints between panels helps to prevent water intrusion to the subgrade and extends the
life of the pavement.
Environmental Responsibility 
During the construction, repair and maintenance activities of these projects various sustainable
practices will be considered and utilized whenever practicable.  These include, but are not
limited to, performing a lifecycle analysis of materials used to ensure that resources being used
and/or recycled are environmentally and economically practical; utilizing onsite water for dust
control and irrigation; the reuse of materials such as concrete and soil; and employing low
emission construction equipment. Alternative materials may be used in concrete, such as fly ash
and slag.

Ramp Lighting Illumination: 
Energy conservation lighting may be used to reduce energy use, as well as provide
benefits for off-airport glare and light pollution. 
400Hz In-Ground Power: 
o  Utilizing 400 Hz power, versus auxiliary power units (APUs) or ground power
units, supports the Port's Century Agenda Goal to Reduce carbon emissions from
all Port operations by 50% from 2005 levels and reduce aircraft-related carbon
emissions at Sea-Tac by 25%. Using 400 Hz power at freighter parking and
remain-over-night (RON) positions is consistent with previous decisions to reduce
noise and emissions. An example of the emission savings of utilizing 400 Hz
power versus APUs for a cumulative 648 hours of B747 or MD11 freighter
aircraft operations is: 
Hydrocarbon      0.2 tons/yr. 
Carbon Monoxide    3.5 tons/yr. 
Nitrous Oxides     1.0 tons/yr. 
Carbon Dioxide    590 tons/yr. 
Community Benefits 
The Cargo 2 and Cargo 6 Hardstands are included in the 2013-2017 Aviation Business Plan as
supporting the goal of operating a world-class airport by anticipating and meeting the needs of
our tenants, customers, and the region's economy by expanding and modernizing existing onairport
cargo facilities. The additional hardstand RON capacity at Cargo 5 is in alignment with
the future goals of the Airport to anticipate and increase passenger aircraft growth and demand. 
This is part of the Airport's goal in having a world class airport that meets the needs of
customers. The apron replacement at Cargo 6 furthers the Airport's business plan objectives to
operate a world-class international airport by ensuring safe and secure operations and by
managing our assets to minimize the total long-term cost of ownership. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Do Nothing. This alternative will perpetuate existing capacity constraints,
neglect customer requirements for the accommodation of increasingly larger aircraft  and
continue to limit the size and number of aircraft that can use these areas. Congested hardstand
conditions would persist and likely worsen. This alternative will not promote air cargo growth 
and does not align with Commission Century Agenda goals or the goal of tripling air freight at
the Airport in the next 25 years. This is not the recommended alternative. 
Alternative 2)  Authorize to advertise and execute a construction contract to enhance the Cargo
2 and Cargo 6 hardstands and to construct a hardstand at Cargo 5 that will increase the RON
aircraft parking.  This alternative is consistent with the goals of the Century Agenda for
promoting growth in air cargo by alleviating capacity constraints, and is consistent with the
Commission's previous actions for development of the Cargo 5 hardstand.  This is the
recommended alternative.
