ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to increase the budget for the
S1 Ramp project by $200,000. The new authorized total project cost will be $1,405,000.
SYNOPSIS 
On April 22, 2014, the Commission authorized the procurement of an Americans with
Disabilities Act (ADA) compliant sloping walkway (or ramp) for installation by Port crews. On
November 12, 2014, a single bid was received and opened. The bid exceeded the project cost
estimated amount by nearly 49 percent. This additional authorization of $200,000 represents the
difference between the project cost estimated amount and the bid plus construction contingency.
This project was included in the 2015  2019 capital budget and plan of finance.
Port staff has carefully reviewed the project in light of these increased costs and has determined
that it remains critical to the effective management of the Airport that the project proceed even
with the increased cost. A ramp will be essential during the summer of 2015 to provide a single
point of entry for international passengers transported to the terminal by bus when airplanes are
required to park at a remote area (hardstand). Remote aircraft parking will be required because
of unavoidable gate shortages for international wide-body flights at the South Satellite. No
project alternative such as re-bidding will allow the ramp to be completed in advance of this
need. 
BACKGROUND 
This project prepared a full design of the ramp structure anticipating that this would broaden the
pool of interested bidders for its fabrication. Unfortunately only one bid was received. While the
bid was higher than expected, staff recommends accepting the bid and authorizing execution of

the contract with the sole bidder. This would allow the ramp to be operational by the busy
summer traffic season of 2015. 
Immediately after receipt of the single high bid, Port staff evaluated available alternatives that
would allow the ramp to be constructed and in operation by June 1, 2015 in order to meet
operational requirements. We reviewed the following options: 
Option 1: Reject the bid, return to design and rebid the project as a public works. This option
could very well increase the number of interested and potential bidders. While this would 
improve competition among bidders, it may not result in a lower bid since many factors go into
bid results including market conditions at the time bids are prepared. This option would require
an additional six months to revise the bid documents and complete the re-bid, pushing the
completion of the ramp to December 2015, which will not provide it by June 2015. For this
reason, this option was not pursued. 
Option 2: Reject the bid, and have Port Construction Services (PCS) fabricate and install the
ramp using a combination of Port forces and on-call contractors. This option could result in a
lower cost than accepting the single bid for fabrication. This option would also allow the ramp
sooner than the option above. However, PCS staff would need to undertake work new to them
such as preparing shop drawings for review and painting the fabricated ramp components for
weather durability. Because they don't undertake these projects regularly, this effort would
combine a steep learning curve with the likelihood of never repeating it. Given these conditions,
there is no guarantee this work could be completed by June 1, 2015. Therefore, this option was
not pursued. 
Option 3: Preferred Option: Accept the bid, and complete the installation by PCS. This option
would require additional funding to complete as the bid amount is higher than the project
estimate. Proceeding with this option would ensure that this facility is complete prior to the busy
summer 2015 traffic season and available to international arriving passengers whose aircraft was
required to park remotely. This option is the only option that meets the critical operational need.
Therefore, given the uncertainty in cost for Options 1 and 2, this option presents a fair and
reasonable bid price to deliver the ramp for operations by June 1, 2015. 
PROJECT JUSTIFICATION AND DETAILS 
Hardstand operations for an international flight will need to move large numbers of passengers
(200-350) quickly and efficiently from the remotely parked aircraft to international arrivals. The
final piece of work required to ensure successful and safe hardstand operations is the ADA ramp
at Gate S1. This walkway will be a permanent, single point of access for all international
passengers arriving via hardstand operations. The only currently available option for getting
passengers from the ramp level to international arrivals is a set of stairs at the future walkway
location which is an unacceptable option for this summer.  A large majority of arriving
international passengers have wheeled luggage, strollers and other carry-on items with them
when they disembark the aircraft. Having then to walk up a long flight of stairs would be

difficult for these passengers and would lead to queuing and long waits at the bottom of the
stairs. The situation would prove untenable.
Additionally, passengers requiring mobility assistance including canes, walkers and wheelchairs
need a ramp to enter the building. Without this new ADA ramp at Gate S1, passengers requiring
mobility assistance and their accompanying family members would require multiple escorts to
assist in getting into the elevators to international arrivals, as well as traversing through the South
Satellite bagwell, which is a dangerous route for passengers due to tugs pulling baggage carts
through the area. 
Project Objectives 
Provide a single point of access for ambulatory and wheelchair passengers between the
ground level, international corridor, and concourse at the South Satellite. 
Improve safety and convenience for passengers. 
Provide a means of access for passengers into and out of the South Satellite during busing
for Satellite Transit System outages. 
Scope of Work 
At Gate S1, remove the extended fixed bridge and stairwell, add an ADA inclined walkway, and
add a tent for passengers to wait under for buses during inclement weather. The project will add
pavement striping to delineate a bus path to and from the site.

Budget Status and Source of Funds 
The Gate S1 Ramp (CIP #C800629) was included inthe 2015-2019 capital budget and plan of 
finance with a budget of $1,205,000. The current budget increase request is due to the single
responsive bid received for the fabrication of the walkway.  The budget increase will be
transferred from the Aeronautical Allowance CIP #C800404 resulting in no net change to the
Airport capital budget. The funding source for this project is the Airport Development Fund.

Lifecycle Cost and Savings 
The life of this asset is estimated to be 15 years. We do not anticipate significant ongoing
maintenance costs. We do, however, anticipate performing refurbishment of the floors, ceiling
material and siding material approximately every 3 to 5 years depending on usage and weather. 
It is estimated that the cost of these refurbishments will range between $5,000-$7,000 per event.
STRATEGIES AND OBJECTIVES 
This project supports the Century Agenda objective to make Sea-Tac the West Coast "Gateway
of Choice" for international travel.  In order to advance this region as a leading tourism
destination and business gateway we need to give traveling passengers a positive experience
when they arrive at Seattle-Tacoma International Airport.

COMMISSION AGENDA

With the goal to double the number of international flights, the Airport has outgrown its gates at
the South Satellite. By adding this much-needed infrastructure at Gate S1 the Airport will be
able to meet the region's air transportation needs more efficiently by improving the flow of
domestic and international passengers. 
The project manager will coordinate with the Office of Social Responsibility to identify small
business opportunities.
