ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to prepare design and
construction bid documents, execute utility agreements, and utilize Port crews for the
Construction Logistics Expansion project at Seattle-Tacoma International Airport for an
estimated $2,468,000. The total estimated project cost is $7,400,000. 
SYNOPSIS 
With the addition of several large construction programs at the Airport, the existing construction
logistics facilities need to be expanded. These facilities currently provide space for contractor
parking, temporary construction trailers, and the delivery and storage of materials and equipment
for both Port and tenant projects. The Construction Logistics Expansion project will expand the
existing construction logistics facilities and renovate the existing remote field offices in support
of the Aviation capital program.  Airline majority-in-interest approval is required and that
process is currently underway with ballots due in November 2014. The current request includes
$420,000 for Port Construction Services to self-perform or execute small works contracts and 
staff expects to seek Commission authorization for the remaining construction in September
2015. 
BACKGROUND 
The construction logistics facilities were originally constructed in 2001 at the Logistics site (see
Attachment A) located in the vicinity of 28th Avenue South and South 192nd St. The logistics
facilities included a 560 stall contractor parking lot, and six construction laydown areas
providing 12.0 acres of support space. The contractor parking lot is used for construction worker
parking for both Port and tenant construction contracts. The construction laydown areas are used

for both temporary construction trailers (remote field offices), and the delivery and storage of
materials and equipment. In 2010 the construction of the Bus Maintenance Facility reduced the
available construction laydown facilities at the Logistics site to 7.7 acres. An additional acre of
construction laydown and logistics facility was provided at the Radisson site (see Attachment B),
located in the vicinity of S 170th St and International Blvd, in 2006. 
In order to support the upcoming Aviation Capital Program the construction logistics facilities
need to be expanded to provide a 900 stall contractor parking lot and a total of 9.6 acres of
construction laydown space. With the completion of the project, the contractor parking area will
be relocated from the Logistics site to the South Employee Parking Lot (SEPL). The current
contractor parking area will then be converted to construction laydown in order to provide the
necessary space. 
Construction Management, Survey, Construction Safety, and the construction section of the
Central Procurement Office are currently located in remote field offices at the Water Tower,
Westside, and Logistics sites (see Attachment C). These facilities were originally constructed as
temporary field offices and have a limited useful life. They now require renovation to maintain 
functionality for an additional 10 years in support of the upcoming Aviation Capital program. 
This authorization request includes the utilization of Port crews and a small works contractor in
order to complete the improvements necessary to relocate the contractor parking area to SEPL.
A future authorization request will include the award and execution of the two major works
contracts that supports the expansion and reconfiguration of the construction logistics facilities
and the renovation of the remote field offices. 
Staff evaluated a number of alternatives for providing the needed construction laydown space.
As explained on page 6, this proposed alternative is the lowest cost alternative. 
Staff will report on the results of the Airlines majority-in-interest balloting due in November.
The airlines were briefed on this project this past August with no significant comments or
concerns expressed. 
PROJECT JUSTIFICATION AND DETAILS 
The existing construction logistics facilities at Seattle-Tacoma International Airport are heavily
utilized during the construction of the Aviation capital program to provide construction worker
parking, and space for temporary construction trailers and the delivery and storage of materials
and equipment. This reduces impacts to existing Airport facilities, and reduces the cost from
contractors charging the Port for these facilities within each construction project. With the
increase in the Aviation capital program over the next 10 years the existing construction logistics
facilities are undersized and need to be expanded to include a 900 stall contractor parking lot,
and 9.6 acres that can be readily adjusted to accommodate the laydown space requirements based
on the size of the construction project.

Project Objectives 
Providing sufficient construction laydown and contractor parking facilities to support the
upcoming Aviation capital program through 2025 
Upgrade the existing SEPL storm water management facilities to meet current NPDES
permit requirements with no impact to the existing streams, wetlands, and associated buffers 
Maintain existing field offices to provide an effective work environment for Port staff 
Minimize investment in facilities that will be displaced by future project actions 
Scope of Work 
The project includes the reconfiguration and expansion of the construction logistics facilities, the
re-use of the SEPL as a contractor parking lot, the upgrade of the SEPL storm water management
facilities, and the renewal of the remote field offices used by Port staff. The key elements
include the following: 
Construction Laydown: The existing construction laydown facilities at the Logistics and
Radisson sites need to be reconfigured in order to maximize the use of the space and support
a wider range of uses, and be expanded to support anticipated demand which displaces the
existing contractor parking area. The redevelopment and expansion of the construction
laydown facilities includes utilities (power, communications, water, and sewer), trenching,
pavement patching, striping, and bollards. 
Contractor Parking: SEPL was originally constructed in the late 1980's and has not been in
use for several years as an employee parking facility. In order to get the parking facility back
into operation to support contractor parking, the lot needs to be cleaned, restriped, signed,
and existing pot holes and damaged curb sections repaired. In addition, the access control
system needs to be replaced. The completion of this work is included in this request and will
be completed by Port Construction Services (PCS). 
SEPL Storm Water Management Facilities: SEPL includes two storm water detention ponds
that were constructed as part of the original facility in the late 1980's. These facilities need
to be upgraded to meet the current NPDES permit requirements. The capacity of the existing
ponds needs to be expanded and protected (e.g., bird netting) and a swale needs to be
constructed for water quality. 
Field Offices: The Port has existing field offices at three locations (Water Tower, Westside, 
and Logistics) that support Construction Management, Survey, Construction Safety, and
Central Procurement Office staff. These facilities are over 10 years old and need
improvements in order to keep them in operation for the next 10 years. Improvements differ
by location but generally include replacement of the heating and ventilation systems, hot
water heaters, roof ladders, roof membrane upgrades, and exterior repair and repainting.
There are two vacant modular facility units at the Westside location that will be demolished
as part of this effort.

Lifecycle Cost and Savings 
Port staff does not anticipate a significant change in the on-going operation and maintenance
costs associated with the construction logistics facilities and the remote field offices. These costs
will continue to be incorporated into the Aviation capital program costs through allocated
overhead. 
The addition of a pond cover to the SEPL storm water management facilities does represent an
increase in the on-going operation and maintenance costs. Depending upon the size and material
used this will be better estimated during the design phase of the project. 
STRATEGIES AND OBJECTIVES 
This project supports the Century Agenda's strategic objective to advance this region as a
leading tourism destination and business gateway since this project supports the Aviation capital
program, which in turn provides the facilities necessary to meet the region's air transportation
needs at the Airport. 
This project also supports the Aviation Business Plan strategies to operate a world-class
international airport by anticipating and meeting the needs of our tenants, passengers and the
region's economy,  and to reduce airline costs as far as possible without compromising
operational and capital needs. This project supports the Aviation capital program, which in turn
provides the facilities necessary to support Airport operations. This project also focused on reutilizing
existing facility assets in order to minimize the overall cost impact.

TRIPLE BOTTOM LINE 
Economic Development 
The Construction Logistics Expansion project supports the Aviation capital program which
represents an investment in our current facilities and supports the long-term vitality of the
Airport and its tenants. 
Environmental Responsibility 
The Construction Logistics Expansion project will upgrade existing storm water management
facilities to meet current permit requirements and support of future development. 
Community Benefits 
The Construction Logistics Expansion project will provide construction logistics facilities for the
Aviation capital program. These facilities will reduce impacts on valuable existing Airport
facilities by construction workers or construction activities in order to continue operations at our
desired level of service for the traveling public. 
Small Business Opportunities 
The project manager  will collaborate with OSR to determine the maximum amount of
opportunities for small business participation. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Reconfigure SEPL to provide construction laydown and contractor parking for
one major project (e.g., International Arrival Facility). Provide additional construction laydown 
facilities at the Radisson and Logistics sites, and provide additional contractor parking at the
Logistics site. Upgrade the storm drainage facilities at SEPL to meet current NPDES permit
requirements; but there is a risk that this cannot be achieved since this alternative represents a
change of use and there would be conflicts with existing stream and wetland buffers. Renovate
the field offices to support the current and anticipated future use by Port personnel. The
anticipated cost for this alternative is $8,500,000. This is not the recommended alternative. 
Alternative 2) Reconfigure the existing construction logistics facilities at the Logistics and
Radisson sites to provide construction laydown. Relocate contractor parking to SEPL. Upgrade
the storm drainage facilities at SEPL to meet current NPDES permit requirements. Renovate the
field offices to support the current and anticipated future use by Port personnel. The anticipated
cost for this alternative is $7,400,000. This is the recommended alternative. 
Alternative 3) Reconfigure the existing construction logistics facilities to provide construction
laydown, and construct additional logistics facilities off-site on undeveloped Port property for
both construction laydown and contractor parking. These additional facilities can be located
either to the north or south of the Airport, but the intent is that they would support only one
major project (e.g., International Arrivals Facility). Provide contractor parking for tenant projects

at SEPL and upgrade the storm drainage facilities to meet current NPDES permit requirements.
Renovate the field offices support the current and anticipated future use by Port personnel. The
anticipated cost for this alternative is $12,400,000. This is not the recommended alternative. 
Alternative 4)  Under this alternative the Port would not provide any facilities for construction
laydown and contractor parking. Each contractor would be required to provide their own
facilities in support of the project. Typically 2-3% of the contractor bid costs are associated with
providing construction logistics for the project. Staff estimates that we reduce these costs by 1-
2% by providing these nearby facilities. Based upon the current Aviation capital program 1% of
the anticipated contractor bid costs is estimated at $12 million. In addition, by not providing
these facilities the local communities would experience a negative impact to their economic
development as property would be used for these temporary facilities instead of in support of the
local community's goals. This is not the recommended alternative.
