COMMISSION AGENDA             Item No.      6b 
Date of Meeting    January 24, 2012 

DATE:    January 12, 2012 
TO:     Tay Yoshitani, Chief Executive Officer 
FROM:    Michael Ehl, Director, Airport Operations 
Wayne Grotheer, Director, Aviation Project Management Group 
SUBJECT:  Airfield Pavement Replacement (CIP #C102573), Runway 16 Center/34 Center
(16C/34C) Panel Replacement (CIP #C800112), Exterior Gate Improvements  
Airline Realignment (CIP #C800472), and Snow Dump Pavement Expansion
(Small Jobs CIP #C800017 WP104647) 
Amount of This Request: $7,320,000      Source of Funds: Airport Development Fund
and Revenue Bonds 
State and Local Taxes Paid: $529,000      Jobs Created: 41 
Total Project Cost: $9,033,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to advertise and execute a
single construction contract comprised of: (1) Airfield Pavement Replacement (CIP #C102573);
(2) Runway 16 Center/34 Center (16C/34C) Panel Replacement (CIP #C800112); (3) Exterior
Gate Improvements  Airline Realignment (CIP #C800472); and (4) Snow Dump Pavement 
Expansion (Small Jobs CIP #C800017 WP104647). This authorization is for $7,320,000, and the
total cost for all four projects is $9,033,000. 
SYNOPSIS: 
Multiple projects to be constructed on the airfield in 2012 have been combined into a single
construction contract in order to minimize disruption to the airlines and Airport patrons.
Advertising these projects in a single contract is wise because separate contracts could result in a
disjointed effort with greater risk to Airport operations. It is common practice to combine
multiple work packages into a single contract for work on the airfield.
Airfield Pavement Replacement (CIP #C102573) includes replacement of deteriorated concrete
pavement panels and joint seal. This request includes $4,707,000 in additional fund
authorization for a total project authorization of $11,801,000 for a multi-year program cost of
$30,800,000, and a potential expense cost for contaminated soil estimated at $80,000.

Runway 16 Center/34 Center (16C/34C) Panel Replacement (CIP #C800112) includes 
replacement of deteriorated concrete pavement panels and joint seal. This request has no 
additional fund authorization. Total funding of $5,650,000 was authorized February 9, 2010. 
Exterior Gate Improvements  Airline Realignment (CIP #C800472) includes additional fuel pits
and aircraft docking systems. This request would authorize $2,613,000 in additional funds for a
total project authorization of $3,112,000. 
Snow Dump Pavement is a small jobs capital project and is included with the major capital
projects for coordination purposes. It has a total cost of less than $300,000 and funds were
previously authorized under the small jobs capital program.
For administrative purposes, to facilitate the distribution of costs during construction, funds for
these projects may be transferred to a single CIP. 
BACKGROUND: 
Starting in 2009, Airport staff conducted a visual survey of pavement on the airfield, to
determine which pavement needed replacing, and in what priority. Work in 2012 will focus on
replacing deteriorated panels on both non-runway areas and Runway 16C/34C. Pavement joint
seals will also be replaced, to take advantage of the already closed areas.
Many of the concrete pavements that are currently failing were originally installed as early as
1969 with an expected service 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 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 Airline Realignment program will require a number of modifications associated with the
airlines that will relocate their gates, to effectively operate in their new locations. The airline
realignment is driven by airline mergers and the consolidation needs of Alaska Airlines which
necessitates the repositioning of gates, holdrooms, and ticketing positions throughout the Airport.
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. The fuel pits and aircraft docking systems are part of the Airline Realignment
program. Expansion of the snow dump area is needed to clearly designate access and storage
areas for the snow clearing operation. The combination of these projects into a single contract
will limit impacts to airline operations and Airport customers.
Project Objective: 
Maintain the structural integrity of pavements by the replacement of deteriorated pavement
panels and joint sealant on non-runway areas and Runway 16C/34C and accommodate the airline

Budget Status and Source of Funds: 
All projects are included in the 2012  2016 capital budget and plan of finance. 
The airfield panel replacement project, CIP # C102573, is part of a multi-year program to replace
deteriorated pavement panels. The funding source will be existing revenue bond proceeds and
future bonds. 
The funding source for the replacement of panels on Runway 16C/34C, CIP # C800112, will be
the Airport Development Fund. 
This funding source for the Exterior Gate Improvements project, CIP # C800472, will be the
Airport Development Fund and existing and/or future revenue bonds.

Lifecycle Costs 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. The fuel
hydrant system is maintained by the fuel consortium, not the Port. The docking guidance system
will require minimum maintenance. The replacement of failing panels and joint sealant will
result in future cost avoidance. 
BUSINESS PLAN OBJECTIVES: 
These projects support the Aviation Strategic Goals in the Business Plan Objectives: operating a
world-class international airport by ensuring safe and secure operations, meeting the needs of

tenants, passengers and the region's economy and managing Port assets to minimize the long-
term total cost of ownership. 
ENVIRONMENT AND SUSTAINABILITY: 
These projects demonstrate environmental sustainability by improving existing Port assets and
better utilizing existing resources. Realignment will allow more effective use of terminal
facilities and this enables efficient operation for airlines at new locations. More sustainable
operations of the Airport are expected to generate lower lifecycle costs of the needed
investments. 
STRATEGIC OBJECTIVES: 
These projects support the Port's strategy to "Ensure Airport Vitality" by maintaining a safe
operating environment as well as maximizing asset utilization. 
TRIPLE BOTTOM LINE SUMMARY: 
Replacement of concrete pavement panels and 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. 
Re-alignment of the airlines increases the long-term ability of the Airport to serve a growing
number of both passengers and airlines. Long-term vitality of the Airport benefits the regional
economy, the local environment, and nearby communities. 
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 Runway 16C/34C and possible need for closure
of the center runway. This alternative would preclude the realignment program as jointly
recommended by the Airline Airport Affairs Committee and the Aviation Division. This
alternative is not recommended. 
2)  Split out the four projects into four separate construction contracts. This alternative
would create greater administrative burden and would heighten concerns related to safety
by increasing the number of individual contractors on the active airfield. This alternative
is not recommended. 
3)  Replace pavement & joint seal and construct exterior gate improvements consisting of
additional fuel hydrant valve pits and aircraft docking system additions during the 2012 
construction season. This is the recommended alternative.
