ACTION ITEM                  Date of Meeting     July 1, 2014 
DATE:    June 24, 2014 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:   Michael Ehl, Director, Airport Operations 
Wayne Grotheer, Director, Aviation Project Management Group 
SUBJECT:  2014 Airfield Improvement Project (CIP #C102573) 
Amount of This Request: $0              Source of Funds: Airport Development
Fund and future revenue bonds 
Est. Total Project Cost: $1,500,000 
Est. State and Local Taxes: $80,000 
ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to reject all bids for the
previously advertised contract for the Airfield Apron Pavement Replacement (CIP #102573) and
NSAT-STS Ceiling Leak Long Term Repair (CIP #C800609) and to re-advertise and execute a 
construction contract for a revised Airfield Apron Pavement Replacement project (CIP #C102573). 
SYNOPSIS 
On April 1, 2014, the Commission authorized the CEO to advertise and execute a single
construction contract for three projects consisting of two CIPs and one expense project to be
constructed on the airfield in 2014. A single bid was received for the contract, which was 29.45% 
over the Engineer's Estimate. The single bid was deemed to be irregular and subsequently rejected.
The requested authorization is to re-advertise a subset of the previous contract in order to address
the most critical items that could impact airport operations. The revised contract will include: 
Distressed concrete pavement on Runway 16C/34C. 
Distressed concrete pavement in three areas surrounding the North Satellite. 
No additional fund authorization is being requested. The estimated total cost of the revised project
is $1,500,000. 
BACKGROUND 
The 2014 Airfield Improvement Project is part of an ongoing pavement management program to
replace aged and distressed concrete pavement and joint sealant in non-runway areas. 
Concrete pavement panels and joint sealant typically have respective design lives of 20 and 10
years. Currently, there is a significant amount of airfield pavement and joint sealant that have far
exceeded their expected service lives. Concrete debris resulting from the deteriorating pavement can

become a hazard for aircraft and personnel. The replacement of the distressed panels is necessary
for the safe operation of aircraft. 
The revised 2014 Airfield Improvement Project will replace approximately 12 deteriorated panels
surrounding the North Satellite and approximately 15 deteriorated panels located on Runway
16C/34C. 
Replacement of pavement joint seal on portions of Taxiways B and W and the North Satellite  
Satellite Transit System (STS) Ceiling Leak Long-Term Repair will be deferred. Taxiways B and
W are located west of the North Satellite and their joint seal replacement is a component of CIP
#C102573. The North Satellite  STS ceiling repair to eliminate leaks is a component of CIP
#C800609. Performing work for these items is weather-sensitive and the schedule for the readvertised
project would likely affect the ability to perform the work. The interior of the STS lobby
would be exposed to weather during replacement of exterior components. 
Replacement of the distressed panels on Runway 16C/34C will be paid for using $300,000 of
expense funds because they will not meet the longevity requirements for capitalization with the
scheduled reconstruction of the runway in 2015. The 2014 operating budget includes $160,000 for
the Runway 16C/34C maintenance. 
The Commission previously authorized use of a project labor agreement for this project.
PROJECT JUSTIFICATION AND DETAILS 
Project Objectives 
Provide structurally sound pavements for current and future customers. 
Provide reliable and appropriate-sized infrastructure systems. 
Minimize total lifecycle cost (capital and expense). 
Minimize operational impacts. 
Scope of Work 
This request includes the following elements: 
Apron panel replacement of approximately twelve panels. 
Runway panel replacement (for RW 16C/34C) of approximately fifteen panels.

Budget Status and Source of Funds 
CIP C102573 is included in the 2014  2018 capital budget and plan of finance. The Runway
16C/34C expense work was included in the 2014 operating budget for $160,000. The Airport will
seek to absorb the increase through savings or use of contingency. The funding sources for these
projects include the Airport Development Fund and future bonds. The Port plans to issue bonds in
2014 to fund a number of projects.

Lifecycle Cost and Savings 
The replacement of concrete panels will result in cost avoidance for maintaining them. Geometric
constraints limit the depth of the pavement that can be constructed at the North Satellite and may
reduce the life of those particular concrete panels.
STRATEGIES AND OBJECTIVES 
This project supports the Port's Century Agenda objective of meeting the region's air transportation
needs at Seattle-Tacoma International Airport for the next 25 years. Ensuring safe and secure
operations and managing assets to minimize the long-term total cost of ownership assist in meeting
this objective. 
TRIPLE BOTTOM LINE 
Economic Development 
Generally, there are no economic impacts related to renewal/enhancement projects since they are
primarily related to preservation of existing business activity. 
Environmental Responsibility 
The project contains appropriate environmental controls to prevent sediments from entering
stormwater systems. Removed concrete panels are anticipated to be crushed and recycled as has
occurred on previous, similar projects.
Community Benefits 
Maintaining runway and airfield apron pavement benefits both our airline customers and travelers.
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
1) Do nothing: This alternative would result in an increasing risk of aircraft ingesting concrete
debris into aircraft engines from distressed pavement, adversely affecting Airport operations. This
is not the recommended alternative. 
2) Replace the deteriorated and aged pavement panels on runway and non-runway areas during the
2014 construction season. This allows for the programmatic replacement of aged and distressed
pavement and avoids operational risk from panels with known distress. This is the recommended
alternative.
