ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to approve and execute a
construction change order for 2015 Apron Panel Replacement (CIP #C102573) to be included in
the Runway 16C/34C Reconstruction (CIP #C800406) or alternatively to advertise and execute a

SYNOPSIS 
The 2015 Apron Panel Replacement project is part of an ongoing Pavement Management and
Maintenance Program (PMMP) as required by the Federal Aviation Administration. The PMMP
includes replacing aged and distressed pavement 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. This project is included in the
2015-2019 capital budget and plan of finance. 
BACKGROUND 
The 2015 Airfield Pavement Replacement project is a continuation of the programmatic
approach of replacing distressed concrete pavement as part of a multi-year program.
Maintaining critical airfield assets with the PMMP maintains the integrity of airfield pavement

and efficient airport operations. Deferring panel replacement could potentially increase risk to
airfield operations, airline operations and drive costs higher in the future.
A project labor agreement will be used for this project in order to reduce risk to operations
caused by potential work interruptions. This was approved by Commission November 11, 2014, 
in conjunction with design authorization.
This project is not impacted by and has no conflict with the proposed Sustainable Airport Master
Plan. 
PROJECT JUSTIFICATION AND DETAILS 
2015 Apron Panel Replacement is the proactive program to maintain the reliability and safety of
airfield pavement, reducing risks of operational and airline damage, delays and increased costs. 
Project Objectives 
Replace failed pavement as part of the PMMP 
Provide stable and safe pavement conditions 
Support the Port's Century Agenda 
Scope of Work 
This project will include demolition and replacement of approximately 20 distressed concrete
pavement panels, temporary and permanent striping and temporary modification to airfield
lighting.

Budget Status and Source of Funds 
2015 Apron Pavement Replacement, CIP C#102573, is included in the 2015-2019 capital budget
and plan of finance. The funding sources will include the Airport Development Fund and future

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 through proactive distressed pavement replacement 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." These projects also support the Aviation
Division's strategic goals of operating a world-class international airport, providing an
extraordinary customer service. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Status Quo - This alternative will not replace distressed concrete pavement. 
Pros:

COMMISSION AGENDA 
Ted Fick, Chief Executive Officer 
April 22, 2015 
Page 4 of 7 
Yearly budget savings, reduced construction traffic on the airfield and
fewer disruptions to airline operations.
Cons: 
Distressed and damaged concrete panels continue to deteriorate, possibly 
to the point of needed emergency repairs at significantly higher cost and
creating even greater risk of producing damaging foreign object debris.
This is not the recommended alternative. 
Alternative 2)  Replace distressed apron pavement during the 2015 construction season by
separate contract. 
Pros:
Maintaining strong and stable runway and apron surfaces through a
consistent and proactive program allows for budget management and
maintains the safety and integrity of the pavement, reducing potential
production of foreign object debris.
Staff inspects the airfield pavement a number of times each year to track
panels and larger pavement sections that are deteriorating and in need of
replacement. Only the areas which have major damage and are in
imminent danger of failing have been included in this alternative. 
Cons: 
Possibility of limited (single bid) or irregular bid which would delay work
outside of dry construction period. 
Limited ability to add/include last minute identified stressed or damaged
panels. 
This is not the recommended alternative. 
Alternative 3)  Replace distressed apron pavement during the 2015 construction season by
Change Order to existing Runway 16C/34C Reconstruction contract. 
Pros:
Greater assurance or work completion in the dry summer construction
season. 
Able to utilize same testing and QC consultant 
More flexibility to accommodate any last minute identified
distressed/damaged panels. 
Reduces soft costs and reduces Construction Management staffing needs 
Maintaining strong and stable runway and apron surfaces through a
consistent and proactive program allows for budget management and
maintains the safety and integrity of the pavement, reducing potential
production of foreign object debris.

replacement. Only the areas which have major damage and are in
imminent danger of failing have been included in this alternative. 
Cons: 
Possible unsuccessful negotiation for the additional work would require
expedited pursuit of Alternative 2. 
This is not the recommended alternative.
Alternative 4)  Replace distressed apron pavement during the 2015 construction season by
Change Order to existing Runway 16C/34C Reconstruction contract or alternatively advertise
and execute a separate construction contract.  Implement whichever alternative the CEO
determines to be the most operationally acceptable and cost effective. 
Pros:
Provides the Port with the ability to choose the most efficient and cost
effective means to complete the work within the 2015 construction season. 
Allows the Port to quickly shift to an alternative procurement method and
still get the project completed in a timely manner. 
Cons: 
Prolonged and unsuccessful change order negotiations may impact the
Port's ability to shift to an alternative procurement method and maintain
the project schedule. 
Project may get delayed to the 2016 construction season and extensive
pavement maintenance would be required in 2015. 
This alternative addresses both operational/safety needs and operational/construction schedule
timing. This is the recommended alternative.
