SUBJECT:  Feeder 101 Taps Replacement (CIP # C800234) 
Amount of This Request:  $500,000         Source of Funds: Airport Development
Fund and future
revenue bonds 
Est. State and Local Taxes: $158,000         Est. Jobs Created: N/A 
Est. Total Project Cost:    $2,706,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to proceed with the Feeder
101 Taps Replacement project; direct staff to prepare design documents; use Port crews to
support site investigation needed to develop the construction contract documents; and use Port
Construction Services to conduct a good faith survey for regulated material. The total amount of
this request is $500,000 and the total projected cost is $2,706,000. 
SYNOPSIS: 
This project will replace components of the electrical system that feed power to the north end of
the Airport that includes cargo warehouse and aircraft areas and Airport maintenance areas.
Feeder 101 is the main feeder cable that supplies electric power to the various facilities along Air
Cargo Road. There are approximately 13 taps that have reached or passed their useful life and
must be replaced. A tap includes the connection to the main feeder and the service cable that
serves each facility.
The project also removes and replaces the existing unit substation at Air Cargo 4 (Port of Seattle
[POS] Maintenance Facility) that includes a transformer and switchboard in the building main
electrical room. This existing equipment has passed its useable life.
Design services will be performed using the existing mechanical  electrical indefinite delivery, 
indefinite quantity service agreement that has already been competitively competed. 
This project was included in the 2013-2017 capital budget and plan of finance.

BACKGROUND: 
When Feeder 101 was replaced by a previous project a decade ago, approximately 13 of the
existing medium voltage feeder taps were left for future replacement. The remaining taps have
now reached or passed their useful life. The taps must be replaced to maintain a reliable and safe
system. New taps will have a projected life of 30 years. 
The POS Maintenance Building unit substation lineup is over 40 years old. The projected life of
the original equipment is 40 years. Replacement parts are no longer available for the unit. A
failure of any of the components will shut down power to the building. A replacement unit can
take up to 18 months to be delivered. Replacing the unit on a predetermined schedule will save
downtime and be less costly. The new equipment will have a projected life of 40 years. 
The new unit substation lineup (transformer and switchboard) will not fit in the existing Airport
Maintenance Building electrical room due to current code requirements. The transformer will be
removed from the building's electrical room and replaced with a new, outdoor, pad-mounted
1000/1500 kVA transformer. A new 480V main switchboard will be placed in the existing
electric room. This allows us to install the equipment per current code. This also allows us to
properly phase construction to minimize the use of temporary measures and down times. 
Traffic along Air Cargo Road has increased with the opening of the Rental Car Facility. The
increased traffic increases the risk of vehicles damaging transformers and pad-mounted
interrupters (PMIs). The Airport has already replaced one transformer due to a traffic accident
with a taxi. This project will add protective bollards to transformers and/or PMIs along Air
Cargo Road in approximately 10 locations. 
PROJECT JUSTIFICATION: 
The existing feeder taps and the POS Maintenance unit substation lineup are past their projected
lives. The equipment is no longer reliable or safe and must be replaced.
The increased traffic on Air Cargo Road facilitates the need for protective bollards at existing
transformers and/or PMIs. 
Replacing the electrical equipment and bollards in a scheduled, controlled manner will save the
Port potentially long downtimes as well as controlling costs. 
Project Objectives: 
Replace the existing taps and feeders along Air Cargo Road. 
Replace the existing transformer and switchgear in the POS Maintenance Building. 
Provide a safe reliable system with a life of at least 30 years. 
Install additional protective bollards at transformers and/or PMIs. 
Minimize downtime and disruption to tenants. 
Complete project on time and within budget.

Budget Status and Source of Funds: 
This project, CIP #C800234, was included in the 2013-2017 capital budget and plan of finance
with a budget of $1,000,000. The budget increase of $1,646,000 has been transferred from
C800404 Aeronautical Allowance, a business plan prospective project, resulting in no net change
to the Aviation capital budget. The budget increase is due to increased soft costs, escalation in
prices, added Regulated Material Mitigation, and the addition of the switchgear/transformer in
Air Cargo #4. The funding sources are Airport Development Fund (ADF) and future bond
proceeds. The 2013  2017 capital budget and plan of finance assumes the Port will need to
issue revenue bonds in 2013 or 2014 to fund a number of capital projects.

Lifecycle Cost and Savings: 
The project replaces existing electrical infrastructure. Operational costs will remain the same
and are factored into existing Aviation Maintenance budgets. 
STRATEGIC OBJECTIVES: 
This project will support our Century Agenda Strategic Objective to triple air cargo volume by
ensuring that the infrastructure is reliable and up to date. 
ENVIRONMENTAL SUSTAINABILITY: 
This project demonstrates environmental sustainability by improving existing Port assets and
better utilizing existing resources. This project will replace existing equipment with new, more
efficient systems. The majority of the existing materials will be recycled. 
BUSINESS PLAN OBJECTIVES: 
The anticipated growth in air cargo will require a stable infrastructure that will remain reliable
for the next 30 years. This supports the Aviation Division's strategic goal of operating a worldclass
international airport by anticipating and meeting the needs of our tenants, passengers, and
the region's economy. 
TRIPLE BOTTOM LINE SUMMARY: 
This project supports:

COMMISSION AGENDA 
Tay Yoshitani, Chief Executive Officer

Page 5 of 5 
The economy by supporting our customers and by continuing to provide service to the
community with the facilities located along Air Cargo Road. 
The environment by recycling the majority of the materials to be removed and by
installing new more efficient electrical equipment. 
Social responsibility through supporting small business opportunities and job creation. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1  Replace the feeders, the unit substation, and add protective bollards on separate
contracts. This can be accomplished; however, this will increase the costs to the Port and to the
contractor. This will also lengthen the schedule, which increases the risk to the Port. This is not
the recommended Alternative. 
Alternative 2  Leave the equipment in place. The equipment would be replaced as it fails.
This alternative represents the biggest risk to the Port due to potential loss of operations and
impact to cargo airlines whose international flight schedules could be interrupted. This is not the
recommended Alternative. 
Alternative 3  Replace all of the feeder 101 taps along Air Cargo Road, replace the existing
POS Maintenance unit substation lineup, and add protective bollards to the transformers/PMIs
along Air Cargo Road. This alternative is the most cost effective and offers the shortest
schedule. The work will be bid as one package and the work will be sequenced to take
advantage of one contract. This is the recommended Alternative.
