SUBJECT:  Design for slot drains, pavement, and joint seal replacement and installation of
temporary common-use equipment at the South Satellite (CIP # C-102573) 
Amount of This Request:  $394,000      Source of Funds:  Airport Development Fund 
Total Project Cost:  $10,500,000 

ACTION REQUESTED: 
Request Port Commission to authorize the Chief Executive Officer to 1) proceed with
project management, design, environmental support, and preparation of 100% design level
construction documents for the replacement of slot drains, pavement, and joint seal at the
South Satellite at Seattle-Tacoma International Airport (Airport), 2) execute and award
outside professional service agreements, 3) pre-purchase common-use gate equipment, and
4) allow Port Construction Services (PCS) to self-perform work, advertise for bids, execute
and award small works construction contracts for common use equipment installation.
Project costs to accomplish this work are estimated at $394,000. The total cost of this
project is estimated to be $10,500,000 within a total estimated multi-year program of
$30,800,000 
SYNOPSIS: 
This project will produce the final design for slot drains (a long, narrow drain system to convey
runoff from the pavement surface), concrete pavement panels, and joint seal replacement at the
South Satellite. The design will include utilities and other scope items related to the project. The
final design will be completed in 2010 and implementation of the portable common use units is
anticipated to occur in early 2011. Port staff will return to the Commission by early 2011 to
request authorization for advertisement and construction funding. 
The scope of work includes the design, acquisition and activation of temporary common use
boarding door workstations for passenger processing activity for flights displaced by this
project. The Port of Seattle (Port) currently provides passenger processing equipment at five
common-use gates impacted by this project: S10, 11, 12, 15 and 16. Closure of these gates,

required by the construction of the project, will cause reassignment of international flights
to gates S7, 8 and 9. These three gates do not have common use equipment. The temporary
common use equipment will allow flights to be shifted to gates that currently do not have
common use equipment and minimize impacts to the airlines and passengers.
BACKGROUND: 
In 2009, Airport staff conducted a visual survey of the non-runway pavement on the airfield, to
determine which pavement needed replacing, and in what order. It was determined that the
South Satellite work should be completed first, due to the deteriorating condition of the
pavement, which is at the end of its useful life. To that end, w ork in 2011 will focus on
replacing pavement as well as associated slot drains around the South Satellite. Pavement joint
seals will also be replaced, to take advantage of the already closed gates.
The slot drain and adjacent concrete were originally installed in 1971 with an expected service
life of 20 years. Typical degradation of the concrete is occurring. In the areas adjacent to the slot
drains the concrete is degrading at an accelerated rate. Joint seal in the area has degraded and in
some cases is nonexistent.
The concrete, slot drain and joint seal work must occur in a phased, gate by gate, fashion to keep
the satellite functional for our airline tenants. Advance acquisition and installation of common
use units is required in order to enable a more efficient shift of airlines between gates to allow
the work in the vicinity of respective gates to proceed. 
This project is part of a multi-year program to replace some of the worst pavement and joint seal
on the airfield. The project will generally replace the most critical pavement first, but will
include other pavement sections when it makes sense. The criticality and order of the pavement
replacement may change over time, based on pavement deterioration, operational impacts, and
available funding. The 2011 project is anticipated to be approximately $10.5 million, which
includes the funds currently being requested. The overall program amount is $30.8 million. 
PROJECT JUSTIFICATION: 
In areas around the South Satellite, the design used for the existing slot drain system is causing
accelerated deterioration of the surrounding pavement. There is also other pavement in the
vicinity of the South Satellite that need to be replaced. Concrete debris resulting from the
deteriorating pavement is becoming a hazard for aircraft and personnel. As the gates are taken
out of service for the pavement and slot drain replacement, it presents an opportunity to also
replace the deteriorating pavement joint seal in the immediate area. 
This project will displace airline operations at gates S10, 11, 12, 15 and 16 to gates S7, 8 & 9
during construction. Gates S7, 8 and 9, while able to accommodate the displaced aircraft, only 
have Delta Airlines passenger processing equipment which cannot be used for flight operations
by other displaced airlines. The temporary common use equipment will facilitate boarding of all
other airline passengers at gates S7, 8 & 9 in a seamless manner.

they are primarily related to preservation of existing business activity. 
STRATEGIC OBJECTIVES: 
This project supports the Port's strategy to "Ensure Airport Vitality" by maintaining a safe
operating environment as well as maximizing asset utilization.

ENVIRONMENT SUSTAINABILITY AND COMMUNITY BENEFITS:
The concrete panel and slot drain repair and maintenance is eligible for a Categorical Exclusion
and Categorical Exemption under the National Environmental Policy Act (NEPA) and State
Environmental Policy Act (SEPA) due to the nature of the project. The environmental review for
the project will be completed before the project is advertised for construction. 
During repair and maintenance activities, various sustainable practices will be considered and
implemented when practicable. These include, but are not limited to, performing a life cycle
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. 
The Airport's ramp area is comprised of a series of concrete pavement panels, and its slot drain 
system services the various Airport concourses. The ramp provides parking and access to the
gate positions for aircraft. The slot drain system allows for drainage of the ramp area.
Maintaining the ramp and slot drain system is critical for preserving access to aircraft parking. 
TRIPLE BOTTOM LINE SUMMARY: 
Replacement of slot drains, concrete pavement panels, and the joint sealant are a financially
responsible way to insure continued access to the gate areas for the airline tenants and continued
gate availability for the traveling public. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
1)  Do nothing: This alternative would result in an increasing risk of aircraft ingesting
concrete debris into aircraft engines around the South Satellite and possible need for
closure of gates. This is not the recommended alternative. 
2)  Replace the pavement, slot drain system, and joint seal over a two year period: The
ultimate result would be the same as the preferred alternative however, the risk of aircraft
ingesting concrete debris increases with time as the pavement deteriorates. Escalation in
construction costs due to inflation and fixed mobilization/demobilization costs will also
occur. Performing the work over consecutive years would cause a prolonged hardship to
the South Satellite tenants. This is not the recommended alternative. 
3)  Replace the slot drains, pavement, and joint seal during the 2011 construction season
(approximately seven months). This is the preferred alternative
