SUBJECT:   Loading Bridge Gate Utilities Improvements (CIP # C800019) 
Amount of This Request: $0             Source of Funds: Existing revenue bonds 
Estimated State and Local Taxes: $567,000    Est. Jobs Created: 21 
Total Estimated Project Cost: $13,211,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to advertise, award, and execute a
major construction contract not to exceed $8,242,000 for Loading Bridges Gate Utilities Improvements
at the South Satellite of Seattle-Tacoma International Airport. No funding is required for this request as
the entire budget for this project has already been authorized. 
SYNOPSIS: 
This authorization continues progress toward all Airport common-use gates having standard utility
capability to serve aircraft potable water and electricity when the aircraft engines are off. Standardizing
utilities at gates helps enable more frequent use of an aircraft gate during each day to make the Airport
more efficient and therefore, significantly delays costly expansion projects to add more gates. This
project has been coordinated with the air carriers involved in the current realignment program so that we
can meet future aircraft requirements. 
On June 14, 2011, Commission authorized full funding for this project along with design and advance
procurement of equipment. In the course of design, staff has decided to include the equipment in the
construction contract rather than a separate procurement, and the construction will be accomplished in
increments. Staff learned that the power requirements of the Boeing Dreamliner 787 are greater than
anticipated. Given the expected deployment of the 787 by airlines at Sea-Tac, staff engaged in some redesign
and altered the contracting and procurement plans. The requested construction contract will
complete potable water and electrical work at the South Satellite. The remainder of the electrical work
at other concourses will be accomplished via later construction contracts after valuable experience is
gained from serving the 787, which started service earlier this year. The 787 has newer technology and
requires a greater level of electrical service than older aircraft. Staff will return at a later date for any

necessary design, scope or budget adjustments that may be needed prior to requesting authorization for
follow-on electrical contracts.
This project was included in the 2013  2017 capital budget and plan of finance. 
BACKGROUND: 
Currently there are 31 Airport-owned common-use aircraft gates on Concourses B and C, and the North
and South Satellites that do not have full aircraft utility capabilities. There are varying amenities at
these gates, including 400 Hz electrical power supply and potable water. This overall improvement
program will bring the 31 "utility deficient" Port-owned gates up to the same standard, including 400 Hz
power and potable water.
The Commission previously authorized design of this project. T his request is to authorize a major
construction contract to update potable water systems at all of the "utility deficient" gates and to replace
outdated 400Hz electrical motor generators owned by Delta Airlines at the South Satellite with Portowned
400Hz electrical motor generators, simplifying operational and maintenance concerns.
Additionally, installation of these hardwired motor generators will eliminate the need for airlines to use
fossil-fuel burning motor generators that are also used at the South Satellite. 
On June 14, 2011, the Commission authorized the entire budget of $13,211,000 (including expense
funds) to finish design, pre-purchase long-lead-time sole-source equipment (including motor generators) 
and construction. In the interim, staff learned from Boeing that the 787 has additional power
requirements and that the 787 will begin international service at a gate on the South Satellite this month.
The rapid deployment of the 787 by airlines to routes that serve the Airport has necessitated research
and re-design and has altered the procurement plan. After extensive research, staff has decided not to
pre-purchase the equipment, but instead to have the successful bidder purchase a specific motor
generator for which a sole source waiver has been obtained. This project initially included providing
400Hz motor generator power at the B concourse as well; however, staff recommends that this work be
delayed until such time that more is known about the 787 motor generator requirements and the
availability of equipment that meets these requirements. Staff will return to the Commission at a later
date for authorization for design and to advertise the construction of the remaining work.
Approximately $5 million of electrical work will be delayed until after valuable experience is gained
from serving the first 787 at the Airport.
PROJECT JUSTIFICATION: 
The majority of work planned under this authorization represents a time critical component in
supporting the broader airline relocation effort while also providing improved operational efficiency
throughout the Airport.
Project Objectives: 
Support the timely relocation of airlines 
Enable the Airport to gain more flexibility to maximize the use of each gate 
Extend the service life of each eligible gate for several more years through refurbishment of major
components and systems to increase reliability and reduce maintenance costs 
Reduce the possibility of a carrier being assigned to a gate without the same amenities as it has at
present

PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
The scope of work for this overall improvement program includes the replacement of the 400Hz system
at the South Satellite and replace the potable water boxes at all North and South Satellite, Concourse B
and Concourse C gates. This includes the replacement of existing equipment where necessary. Prior to
determining replacement versus refurbishment, a condition survey was prepared by an independent
contractor. Refurbishment scope of work included renewal and replacement of primary systems,
equipment, components and finishes in order to extend their useful life. Purchase of the 400 Hz motor
generator currently owned by Delta Airlines at the South Satellite is included, as appropriate for the
corresponding work. Design will be completed using an existing previously authorized design contract.
This design will be completed prior to advertising the construction contract.

CPE Impact             CPE will increase by $0.10 in 2014, but no change to the
business plan forecast as this project was included. The
airlines will realize lower operating and maintenance costs. 
Lifecycle Cost and Savings 
Annual operating and maintenance costs have been calculated by Aviation Maintenance at $33,046 per
gate per year or a total of $495,685 for the first year plus an estimated 3% inflation escalation thereafter.
Based upon actual costs for 2012 and budgeted costs for 2013 and beyond, additional future full time
equivalent (FTE) staff members will be required to maintain the added gates and the future FTEs are
included within the cost identified above. The additional Airport costs offset the lower operating and
maintenance costs realized by the airlines. The Airport will efficiently centralize the work to optimize
the overall costs, and will report the CPE cost shift when communicating with the airlines.
STRATEGIC OBJECTIVES: 
The Gate Utilities Improvements Project supports the Century Agenda objective of meeting the region's
air transportation needs at Sea-Tac for the next 25 years by providing the airlines with greater facility
flexibility. Flexible gate operations will allow for greater and more efficient use of the Airport's existing
facilities. 
Air carriers have continually vied for increased market share since the passage of the Airline
Deregulation Act of 1978, thereby driving nearly constant change in their facility requirements.
Creating a flexible, common-use environment allows carriers and the Airport to spend fewer capital
dollars remodeling facilities as market conditions change. More carriers are able to share the same
facilities without continual redesign and construction to customize the operating environment to their
specific proprietary needs. This also increases total Airport through-put rates, within the existing
terminal footprint, as passenger volumes continue to increase. 
ENVIRONMENTAL SUSTAINABILITY: 
The new and refurbished Gate Utilities will reduce the number of staff hours necessary for maintaining
and repairing the gates that have reached or exceeded their optimum design life. The project will
facilitate greater utilization of gates throughout the Airport, thus reducing the potential need for, and the

environmental impact of, major new and costly construction to increase the total number of gates and
associated holdrooms over time.
BUSINESS PLAN OBJECTIVES: 
This project supports the Airport's strategy to operate a world class international airport by anticipating
and meeting the needs of our tenants, passengers and the region's economy. Minimizing new facilities
construction requirements by making new operational improvements with up-to-date equipment and
technology helps to minimize costs to the airlines, thereby supporting the Airport's strategy to reduce
airline costs. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
ALTERNATIVE 1: Do nothing: Leave the Gates as-is and require airlines to negotiate new ownership,
or remove, and/or purchase gates for preferential services. This would require negotiation agreements
with the airlines and would continue to complicate future moves. This alternative is not recommended.
ALTERNATIVE 2: Replace the utilities at gates as described in order to optimize gate flexibility,
alleviate conflict between ownership and user, and accommodate growth. This is the recommended
action.
