ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to: (1) develop, advertise, and
execute an alternative public works delivery using the design-build (DB) method for the
Concourse D Hardstand Terminal Project at Sea-Tac International Airport with a total project
cost estimated at $38,400,000 and (2) authorize the use of Port crews for preliminary work in
support of the project. 
SYNOPSIS 
The airport is currently experiencing a shortage of gates and the related ability to accommodate
passenger loading/unloading at remote facilities. With the temporary loss of gates during the
construction of the International Arrivals Facility (IAF), North Satellite Expansion (NSAT) and
other future projects, compounded with the unprecedented growth in passenger traffic, this
shortage will be exacerbated. It is widely accepted that it will be necessary to operate inbound
and outbound aircraft from remote hardstand locations, busing passengers to and from the
terminal building. In order to accommodate these passengers, additional facilities with dedicated
holdroom and passenger processing space are needed. 
To provide for remote hardstand operations, this project will construct a 32,500 Square Foot (SF) 
building on the east side of Concourse D in the existing North Ground Transportation (GT) Lot.
This facility will house up to seven gate lobbies, or holdrooms, for hardstand operations. It is
expected that extensive hardstand operations will be required prior to summer of 2018. In order
to meet this schedule, staff recommends a design build alternative public works delivery method.
It is anticipated that this facility will have a useful life of 20 years.

BACKGROUND AND JUSTIFICATION 
Passenger traffic at Sea-Tac Airport continues to break records and has increased each month for
the past 31 straight months (since November 2013). Passenger traffic is up 10 percent for 2016
compared to 2015. This growth in passenger traffic is mirrored in growth in the number of airline
operations as well. This year, the number of flights arriving during peak periods is greater than
the number of available contact gates where aircraft can be connected through a passenger
loading bridge to the terminal building. 
In 2015 and 2016, airlines have participated in limited trial operations at remote hardstands. In 
2017, construction activities for two large projects, IAF and NSAT, will take existing gates out
of service for several years. To accommodate operations when sufficient gates are not available,
the airport will institute hardstand arrivals and departures where passengers are bused between
the terminal building and remotely parked aircraft. Since every gate will be in use and every 
holdroom will be occupied when hardstand operations are activated, the airport must construct
associated waiting areas for passengers for these flights. 
Today, the airport has two locations where buses from remote hardstands can drop arriving
passengers into the terminal building: Gates S1A and A6A. Both locations are adjacent to
functioning terminal connected contact gates. Both locations offer a sloped walkway ramp
between the bus drop off location and the terminal building concourse. Because both gate
holdrooms were designed solely to accommodate their primary gated flights, neither gate has
separate holdroom facilities for a departing hardstand bus operation. 
Departing flights from a remote hardstand require four basic elements: 1) Holdroom facilities to
process and hold passengers waiting to board their flights; 2) Ground access for passengers to
board the buses; 3) Buses to transport passengers to the hardstand aircraft parking (along with
boarding equipment) and, 4) Ground Service Equipment (GSE) for servicing aircraft at the
hardstand location. 
This past year the Airport began two capital projects to provide remote hardstand operations
capacity. The first is the Gate D6 Holdroom Improvements project (C800771). The design is
complete and is scheduled to be in use March 2017. This will provide an additional sloped
walkway ramp and make use of an otherwise vacant 2500 SF holdroom on Concourse D for up
to two staggered flights. The other is Concourse B Ramp Level Holdroom project (C800761), for
which the Commission authorized construction in July 2016 and is scheduled to be occupied in
May 2017. It will provide holdroom space of 3,400 SF to serve up to two staggered flights and
ramp access to bus transport. 
In 2015, AV Planning and Operations staff determined that the hardstand peak demand could 
eventually rise to 11-13 simultaneous operations in the 2018-19 timeframe. Airport staff agreed 
that the North Ground Transportation lot adjacent to Concourse D was the best location for a
holdroom facility to support these operations.

The Concourse D Hardstand Terminal will be directly linked to Concourse D by a bridge and to
the North Satellite Train System (STS) Main Station landing through a passenger covered
walkway. This location also allows for the simultaneous circulation of sufficient numbers of
dedicated buses to/from remote hardstands for the six to seven holdrooms without impeding
existing gates and ramp activities. 
Construction and use of the Concourse D Hardstand Terminal will require the relocation of all
operations utilizing the North Ground Transportation lot. Preliminary planning with Airport
Landside Operations has determined that these Ground Transportation operations can be
accommodated in other Main Terminal adjacent facilities and areas.
Staff will be seeking authorization shortly via an additional request to procure equipment
necessary to support remote hardstand operations. This will include additional dedicated airfield
passenger ramp buses and ground support equipment such as boarding stairs, ground power units
and PC Air units. 
PASSENGER EXPERIENCE AND PROJECT DETAILS 
Passengers departing via the Concourse D Hardstand Terminal would begin their journey in the
same way as any passenger with a flight departing from Concourse D. They would walk through
Concourse D and across a connector bridge onto the upper level mezzanine of the new two-story
Concourse D hardstand terminal. From the mezzanine, passengers will be able to view out into
the entire space of the building and locate their gate. 
The building will be light and airy with a sky-lighted curved roof structure, and display colors
and patterns with a Pacific Northwest feel. The mezzanine will provide modest concessions and
a place to sit and relax. From the mezzanine, one will be able to walk down the stairs or a gently
sloped ramp to the ground level and departure gates. 
On the ground level, there will be a number of amenities for passengers to use while waiting,
such as electric charging stations, free Airport Wi-Fi, concessions and restrooms. Passengers
would depart by walking through the gate door to a waiting bus instead of directly onto the
aircraft. The bus will then take passengers to the waiting remotely parked aircraft. 
The expected utility of the Concourse D Hardstand Holdroom is 20 years. Based on current
forecasts and development plans, staff anticipates it will be used as hardstand holdroom for 10 to
15 years depending on how long it will take to provide additional gate capacity connected to a
new North Terminal as envisioned under the Sustainable Airport Master Plan (SAMP). When
the facility is no longer needed for passenger operations,  an evaluation of the facility use,
forecasted needs and the development plans of the airport should be undertaken to determine
next steps for the building, likely removal.

Scope of Work 
This project will construct a 32,500 SF building on the East side of Concourse D in the existing
North Ground Transportation Lot. This facility will be a metal building system and will house
six to seven holdrooms for the hardstand operations connected to Concourse D by a connector
bridge. The project will install common use casework and passenger processing equipment as
well as passenger amenities including seating, Wi-Fi, restrooms and limited concessions. Outside
the building, the project will delineate passenger load and drop off zones for the airfield
passenger buses. The project will also add a passenger ramp and covered walkway down to the
mid-level of the North Main (STS) Station. The relocation of the American Airlines storage
shed and the POS garbage compactor will be required as enabling projects.

Lifecycle Cost and Savings 
The expected life of the Concourse D Hardstand Terminal is 20 years, all assets associated with
this project will be determined with this in mind. The major assets associated with this project
will be associated with the mechanical, electrical, building envelope, selection of fixtures and
materials. Aviation maintenance anticipates there will be some incremental costs associated with
the construction of this facility. 
STRATEGIES AND OBJECTIVES 
This project supports the Port's Century Agenda objectives of meeting the region's air
transportation needs at the Airport for the next 25 years by providing critically needed passenger
holdroom space with passenger processing equipment and a busing area to facilitate
hardstand/off-gate aircraft operations. 
This project will also seek to support the Port's Century Agenda objective to be the greenest and
most energy efficient port in North America and the strategy for a sustainable Airport to pursue
LEED Certification for all new Port projects by seeking LEED vs. 4 Silver Certification. There
are opportunities to meet increased energy needs through conservation and renewable resource,
meet agency requirements for storm water and reduce air pollutants and carbon emissions. This
facility will be designed and built to meet current building, electrical, mechanical and energy
codes. The restrooms water closets will be low-flow. Interior finishes will include all paints and
adhesives that are low in Volatile Organic Compounds (VOCs), and various interior materials, as
applicable, will use recycled content materials.

The construction of this project presents a number of small business opportunities. The project
team is working with the Port's Economic Development Division's Small Business Team to
maximize small business utilization efforts for this project. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Status Quo  Do not design or construct a hardstand terminal 
Cost Implications: $0 
This option does not provide new facilities in the terminal for facilitating hardstand operations.
During times of gate shortage, airlines would be required to wait on the ramp until a gate is
available or run hardstand operations without a dedicated facility for processing hardstand
passengers. 
Pros: 
This alternative does not require a capital investment. 
Cons: 
This alternative would potentially delay aircraft arrivals and departures, significantly
degrading the quality of passenger experience at Sea-Tac. 
This alternative would potentially lead to airlines having to process departing
hardstand passengers in severely congested holdrooms already being used for other
flights. 
This alternative does not give airlines a dedicated space to provide customer service
and process passengers for hardstand departures.
This is not the recommended alternative. 
Alternative 2  Build a Hardstand Terminal in an alternate location. 
Cost Implications: Central Terminal Location = $25 - $30M; Cargo 4 South=$65-$80M. 
Pros: 
Preserves the North GT Lot for Ground Transportation functions. 
Cons: 
A decision analysis was completed in consultation with airlines and all other potential
locations for this facility were ruled out due to cost, operational impact or customer
service degradation. 
Specific concerns with the Central Terminal location are the loss of aircraft parking
positions and traffic congestion (Vehicular and Aircraft) at a critical central point of
the ramp. The airlines consider these fatal flaws with the location. 
Specific concerns with Cargo 4 South location are remoteness and overall cost.
Staffing and customer service would most likely be impacted. 
This is not the recommended alternative.

Alternative 3    Build the Concourse D Hardstand Terminal via Design-Bid-Build
procurement method. 
Cost Implications: $40.6M 
Pros: 
Traditional construction delivery method 
Cons: 
This alternative would not provide a Concourse D hardstand terminal until 1st Qtr.
2019 and does not meet the summer 2018 in use date required to meet operational
demands. 
This is not the recommended alternative 
Alternative 4  Build Concourse D Hardstand Terminal via Design-Build procurement
method. 
Cost Implications: $38.4M 
Pros: 
This alternative meets the schedule required to meet operational demands by having
an in-use facility in the summer of 2018. 
Cons: 
Passengers will need to depart the holdroom and go up to the Concourse Level in
order to reach amenities like dining or retail, some concession will be located in the
new building. 
Eliminates North GT Lot for airport charters and Cruise ship bus operations.
Alternatives are in process for the relocation of these functions. 
Design Build will require the need to decide specifically what we want early in the
process and stick to it, in order to get the cost and schedule efficiencies of the method. 
This is the recommended alternative.
