ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to 1) design, prepare 
construction documents, and implement temporary measures as necessary to replace distressed 
pavement and joint sealant for the 2015 Airfield Pavement Replacement Program at  Seattle-
Tacoma International Airport (Sea-Tac) in the amount of $200,000 and 2) for the utilization of a
project labor agreement (PLA) for this project. The total estimated project cost is $1,761,000. 
SYNOPSIS 
This project is part of an ongoing Pavement Management and Maintenance Program (PMMP) as
required by the FAA. The PMMP includes replacing  aged and distressed  pavement and joint
sealant in non-runway areas. Many sections of airfield pavement have exceeded  their 20-year 
service life and have become cracked and damaged. The  PMMP is necessary for safe and 
efficient aircraft operations.  Replacing damaged pavement on the airfield supports the long-term
strategy of the Port's Century Agenda objective to "Meet the region's air transportation needs at
Seattle-Tacoma International Airport for the next 25 years." This project is included in the 2015
2019 capital budget. 
BACKGROUND 
The 2015 Airfield Pavement Replacement Program is a continuation of the programmatic
approach of replacing distressed concrete  pavement panels and joint sealant as part of a multiyear
program. 


Template revised May 30, 2013.

It is estimated, based on historic panel distress levels that approximately 12 panels on the airfield, 
in random locations, will need to be replaced by 2015. Work will also include joint sealing
taxiway B and taxilane W, between taxiways N and Q. 
Depending upon where pavement panels are replaced, it may be necessary to design and 
implement temporary measures, to mitigate airline impacts due to aircraft gate closures. 
Closure of gates can occur if distressed pavement panels are found near gates, which may cause 
reassignment of domestic and international flights to alternate gates. Port staff will return to
the  Commission  to request  additional funding  in the  event  that extensive  temporary 
modifications for reassigning gates and parking areas are required that  exceed the authorized 
funds. 
The current budget for CIP C102573 is $24,602,213. The funds utilized through the end of the
2014 construction season are expected to be $22,841,213. The current estimate for the 2015
Airfield Pavement Replacement Program is $1,761,000. 
This project may also be bundled with other 2015 Airfield Improvement Projects (AIP) to
increase efficiencies between AIP contracts. This would be addressed when Port staff returns to
Commission for Construction Authorization. 
Maintaining critical airfield assets supports the Port's Century Agenda objective to meet the 
region's air transportation needs at Seattle-Tacoma International Airport for the next 25 years. 
The PMMP maintains the integrity of airfield pavements and efficient airport operations. 
Deferring panel and joint sealant replacement could potentially increase risk to  airfield
operations and drive costs higher in the future. 
Project Labor Agreements have been used on past airfield projects in order to reduce risk to
operations caused by work interruptions. Staff recommends that this project utilize a project
labor agreement. 
PROJECT JUSTIFICATION AND DETAILS 
Project Objectives 
Replace aged pavement and joint sealant as part of the PMMP 
Provide stable pavement conditions 
Support the Port's Century Agenda 
Scope of Work

striping and lighting and other scope items related to the project.

CPE Impact             $.01 by 2016, but no change to business plan

Lifecycle Cost and Savings 
Annual Operating and Maintenance costs are not anticipated to change appreciably. The 
replacement of concrete panels will result in cost avoidance for maintaining them. 
STRATEGIES AND OBJECTIVES 
Maintaining critical airfield assets supports the Port's Century Agenda objective to "Meet the 
region's air transportation needs at Seattle-Tacoma International Airport for the next 25 years". 
TRIPLE BOTTOM LINE 
Economic Development 
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  long-term cost of ownership. 
Environmental Responsibility 
During repair and maintenance activities, various sustainable practices will be considered and 
implemented when practicable. 
Community Benefits 
Increasing safe operations at Seattle-Tacoma International Airport allows the community and
local business owners to prosper from the jobs and passengers the airport generates. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
1) Do nothing: This alternative would result in an increased risk to airfield operations as
pavement failures occur and an increased risk to airfield safety from concrete  debris 
resulting from distressed pavement.  This is not the recommended alternative. 
2) Replace distressed pavement and joint seal on the airfield during the 2015  construction 
season. This allows for the programmatic replacement of aged and distressed pavement as well
as replacement of joint seal. This is the recommended alternative.
