SUBJECT:  2013 Airfield Apron Pavement and Joint Seal Replacement (CIP#102573)

Amount of This Request:  $8,967,000    Source of Funds:  Existing Revenue Bond

ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to advertise and execute a
single construction contract comprised of Airfield Panel Replacement and Joint Seal
Replacement (CIP #102573) and Runway 16C/34C Panel Replacement. This authorization
request is for $8,967,000, and the estimated total cost of the complete project is $9,377,000. 
Authorization is also requested to perform this contract under a project labor agreement (PLA). 
SYNOPSIS: 
Multiple projects to be constructed on the airfield in 2013 have been combined into a single
construction contract in order to minimize disruption to the airlines and Airport patrons.
Advertising these contracts as one project is advisable due to the coordination requirements for
multiple jobs affecting the airfield movement area in multiple locations. 
This year's pavement and joint seal replacement project is part of a comprehensive plan to
replace the most damaged, aged, and travelled concrete on the airfield as well as replacing failed
pavement joint seal. 
Runway 16C/34C Panel Replacement includes replacement of deteriorating concrete pavement
panels and joint seal. Runway 16C/34C is scheduled to be replaced in 2016. Replacement of
these panels will be paid for as an expense project because it does not meet the requirements for
capitalization. 
Estimated total project cost includes $200,000 previously authorized for design of the panel and
joint seal replacement and $210,000 of expense funds for panel replacement on Runway
16C/34C.

In return for the Port's promise to require in its bid specifications that all successful bidders
agree to be covered by a PLA, unions promise labor peace through the life of the contract. The
provisions of a PLA will help ensure that this project is completed during one summer
construction season, minimizing the impact on international and domestic travelers and carriers. 
Funding for this project is included in the 2013-2017 capital budget and plan of finance. 
BACKGROUND: 
Starting in 2009, Airport staff conducted visual surveys of pavement on the airfield to determine
which pavement needed replacing, and in what priority. Work in 2013 will focus on replacing
deteriorated panels on non-runway areas. Pavement joint seals will be replaced in both taxilane 
and taxiway areas. 
Many of the concrete pavements that are currently failing were originally installed as early as
1970 with a design life of 20 years. Typical degradation of the concrete is occurring. The
concrete and joint seal work must occur in phases to minimize impacts to airline operations.
The airfield pavement replacement is part of a multi-year program to replace some of the worst
pavement and joint seal on the airfield in non-runway areas. The project will replace areas of
concrete most susceptible to deterioration due to repeated aircraft loading and age and current
condition of the pavement. Additional non-runway panels may be replaced if they become
unserviceable. 
It is necessary to use expense funds for the 16C/34C runway panel replacement due to the
planned total replacement of the runway in 2016. There are currently six panels on runway
16C/34C identified for replacement and another 34 that are being monitored. Given that
pavement distress will continue to occur between now and construction, additional panels will
likely be added. Staff believes that the $210,000 should be enough to cover the costs, should a
small number of additional panels require replacement this year. 
PROJECT JUSTIFICATION: 
Much of the concrete pavement on the airfield has exceeded its service life and deteriorated to
the point of needing replacement. Concrete debris resulting from the deteriorating pavement can
become a hazard for aircraft and personnel. The replacement of pavement panels requires
phasing by area. Replacing joint seal is the primary method for extending the life of concrete
pavement. 
Project Objectives: 
Maintain the structural integrity of the pavements by the replacement of deteriorated
and aged pavement panels and joint sealant on runway and non-runway areas. 
Replace joint sealant between existing concrete panels on non-runway areas in an effort
to prolong the life of the existing concrete.

Lifecycle Cost and Savings: 
Annual Operating and Maintenance costs are not anticipated to change appreciably. The replacement
of concrete panels and joint seal will result in cost avoidance for maintaining them. 
STRATEGIC OBJECTIVES: 
This project supports the Century Agenda objective to "meet the region's air transportation needs at
Sea-Tac Airport for the next 25 years" by maintaining a safe operating environment as well as
maximizing asset utilization. 
ENVIRONMENTAL SUSTAINABILITY: 
During repair and maintenance activities, various sustainable practices will be considered and
implemented when practicable. These include, but are not limited to, performing a lifecycle 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. 
BUSINESS PLAN OBJECTIVES: 
This project furthers the Airport's business plan objectives to operate a world-class international
airport by ensuring safe and secure operations and by managing our assets to minimize the total longterm
cost of ownership. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
1.  Do nothing. This alternative would result in an increasing risk of aircraft ingesting concrete
debris into aircraft engines on non-runway areas and Runway 16C/34C resulting in the
potential need for closure of ramp areas or the center runway. This alternative is not
recommended. 
2.  Replacement of pavement and joint seal material in non-runway areas. Replacement of the
most distressed concrete panels on Runway 16C/34C. This is the recommended
alternative.
