ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to 1) utilize Port crews, and
2) advertise, award, and execute a major public works contract for reconfiguration of the
construction laydown facilities as part of the Construction Logistics Expansion project at Seattle-
Tacoma International Airport for an additional $4,447,000. 
SYNOPSIS 
With the increasing capital construction program at the Airport, the existing construction
logistics facilities need to be reconfigured. 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. This authorization request allows the reconfiguration of the
construction laydown facilities that support temporary construction trailers, and the delivery and
storage of materials and equipment. While this project is included in the 2015  2019 capital
budget and plan of finance, the current request also reflects a $460,000 capital budget increase
due to identified risks from previous lessons learned which include anticipated unsuitable
material conditions ($360,000) and additional electrical improvements ($100,000). 

The Commission earlier approved the design for both the construction laydown facilities and the
field offices, and design and construction for the contractor parking lot. T oday's request
supports the construction of the construction laydown facilities.  Staff will seek separate
Commission authorization for the renovation of the field offices later this year.

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 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 space for the delivery and
storage of materials and equipment. These facilities enable contractors to provide lower bid
prices to the Port.
In 2010, the Bus Maintenance Facility was constructed in a portion of the Logistics site, reducing 
the available construction laydown area from 12 to 7.7 acres. With the expansion of the Aviation
capital program, the construction logistics facilities need to be reconfigured to provide a 900 stall
contractor parking lot and a total of 9.6 acres of construction laydown space.
In addition, Port construction contract support services including Construction Management,
Survey, Construction Safety, and Central Procurement Office staffs are currently located in
remote field offices at the Water Tower, West Side, and Logistics sites (see Attachment B).
These facilities are more than ten years old and require renovation to maintain functionality for
an additional 10 years in support of the Aviation capital program. 
This project is planned to be completed as three separate efforts as described in the paragraphs
below. 
Contractor Parking 
The contractor parking function will be relocated from the current logistics site to the old South
Employee Parking Lot (SEPL) that is now closed and located just north of the construction
logistics facilities. This will allow the existing contractor parking facility to be reconfigured and
used for construction laydown. In order to get SEPL back into operation to support contractor
parking, a combination of Port crews and small works contracts will be used for construction.
This work was previously authorized by the Port of Seattle Commission on October 28, 2014, 
and the work is underway. This effort is forecast to remain on budget (total cost of $595,000)
and anticipated to be complete by this August. The SEPL storm water management facilities
also need to be upgraded to meet current permit requirements for water quality. This work is
planned to be completed as part of the construction laydown improvements described below. 
Construction Laydown 
The existing construction laydown facilities at the Logistics site need to be reconfigured in order
to maximize the use of the available space in support of the Aviation capital program. This
work, and the storm water management facilities, was originally planned to be completed by a
major works construction contract for a total cost of $5,355,000.  The design of these
improvements was previously authorized by the Port of Seattle Commission on October 28, 2014
and is well underway. Based upon the anticipated construction schedules for the Aviation capital

program a portion of this work needs to be accelerated and staff proposes the work be completed
in two phases. Phase one would include the work in Logistics Lots 1 and 2 and construction 
would be completed in 2015 through a combination of Port crews and small works contracts.
Phase two would include the remaining construction laydown facilities (Logistics Lots 3 and 4,
and the old contractor parking lot), and the upgrade of the storm water management facilities,
and would be completed by a major works construction contract in 2016. The total cost of these
improvements has increased from$5,355,000 to $5,755,000. The cost increase is attributed to 
anticipated unsuitable material conditions and additional electrical improvements. Both of these
were identified as risks in project definition based upon lessons learned from the construction of
the Bus Maintenance Facility and Cell Phone Lot site investigations, respectively, and design
work has now shown that additional budget is needed. This authorization request includes the
construction of these improvements (both phase one and phase two). 
Field Offices 
The Port has existing field offices at three locations (Water Tower, West Side, and Logistics)
that house Construction Management, Survey, Construction Safety, and Central Procurement
Office staff. The renovation of these facilities was originally planned to be completed by a
major works construction contract for a total estimated cost of $1,450,000. The design of these
improvements was previously authorized by the Port of Seattle Commission on October 28, 2014 
and is currently underway. Staff has recently completed the existing condition assessment of the
field offices and has determined that more work is required than was previously anticipated.
This was an identified risk in project definition and staff will continue to monitor these costs as
the design progresses, however, additional budget may be required to complete this work. A
future authorization request will be required for the construction of these improvements. 
Sustainable Airport Master Plan 
The Aviation Division is underway with the Sustainable Airport Master Plan (SAMP) and
alternatives have been identified that may displace the contractor parking lot, construction
laydown area, and field office locations in approximately ten to fifteen years. The development
of alternative Port-owned property for construction logistics facilities was explored during the
planning phase of this project. The sites evaluated have the same risk of displacement by future
SAMP development, but costs were higher (estimated at $10-$15M depending upon the site). 
Staff recommends proceeding with the current reconfiguration as the best lowest cost approach. 
PROJECT JUSTIFICATION AND DETAILS 
The existing construction logistics facilities at Seattle-Tacoma International Airport will be
heavily utilized during the construction of the Aviation capital program in order to limit impacts
to on-going Airport operations. With the increase in the Aviation capital program over the next
10 years the existing construction logistics facilities need to be reconfigured to include a 900
stall contractor parking lot and 9.6 acres of flexible construction laydown space.

Project Objectives 
Provide sufficient construction laydown and contractor parking facilities to support the
anticipated Aviation capital program through 2025 
Upgrade the existing SEPL storm water management facilities to meet current 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 may be displaced by future project actions 
Scope of Work 
The project includes the reconfiguration of the construction logistics facilities, the re-use of
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 Logistics site needs to be reconfigured in order to maximize the
use of the space and support a larger number of temporary construction trailers. The
redevelopment  of  the  construction  laydown  facilities  includes  utilities  (power,
communications, water, and sewer), trenching, pavement patching, striping, lighting and
bollards. 
Contractor Parking: SEPL was originally constructed in the late 1980's and has not been in
use for several years. In order to get the 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. 
SEPL Storm Water Management Facilities: SEPL includes two storm detention ponds and
biofiltration swales that were constructed as part of the original facility in the late 1980's.
The biofiltration swales need to be upgraded to meet current permit requirements for water
quality. 
Field Offices: The Port has existing field offices at three locations (Water Tower, West Side, 
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 facilities at the West Side location that will be demolished as part of
this effort.

The total expense budget for this project is $1,278,000 and includes the SEPL improvements for
contractor parking ($555,000), utility improvements for the construction laydown facilities
($440,000), expense costs associated with the field office renovation ($153,000), and costs to
relocate existing field offices during the construction of the construction laydown facilities
($100,000). The $460,000 capital budget increase is attributed to anticipated unsuitable material
conditions ($360,000) and additional electrical improvements ($100,000). 
Budget Status and Source of Funds 
The Construction Logistics Expansion Project (CIP #C800688) was included in the 2015-2019 
capital budget and plan of finance as a committed project with a total capital budget of
$6,122,000. Additional budget of $460,000 was transferred from the Aeronautical Allowance
(#C800404) to provide a total capital budget of $6,552,000 to support the completion of the
construction laydown improvements. As the design progresses for the renovation of the field
offices additional budget may be required to complete that work. The funding source for this
project is the Airport Development Fund and future revenue bonds. The Airlines approved this
project as part of the November 2014 majority-in-interest ballot.

Port staff does not anticipate a significant change in the on-going operation and maintenance
costs associated with the construction logistics facilities and remote field offices. These costs
will continue to be incorporated into the Aviation capital program costs through allocated
overhead. 
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. 
Community Benefits 
The Construction Logistics Expansion project will provide construction logistics facilities for the
Aviation capital program which will reduce the impact to existing Airport operations and provide
an increased level of service for passengers and the traveling public. In addition, staff will work
with the Office of Social Responsibility to determine small business participation opportunities,
in accordance with Resolution No. 3618. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Relocate Contractor Parking Only 
Under this alternative the contractor parking improvements would be completed and contractor
parking would be  relocated to SEPL  later this year. The  remaining improvements for
construction laydown, SEPL storm water management, and field offices would not be completed.
The total estimated cost for this alternative is $1 Million. This is not the recommended
alternative. 
Pros: 
Provides the necessary space for contractor parking (900 parking stalls) 
Minimizes the facility improvements in an area potentially impacted by future SAMP 
development 
Cons: 
Adequate construction laydown facilities for temporary construction trailers would not
be provided, resulting in additional construction bid costs.  Typically 2-3% of the
contractor bid costs are associated with providing construction logistics for a project.
Staff estimates that we reduce these costs by 1-2% by providing these nearby facilities.
Based on the committed Aviation capital program, 1% of the anticipated contractor bid
costs is estimated at $13 million. 
The field offices would not be renovated in order to extend their useful life. Staff may
need to be relocated as the roofing, plumbing, heating and ventilation systems continue
to fail on a regular basis making the field offices unsuitable for work. 
SEPL storm water management facilities would not be updated to meet current permit
requirements. 
Negative impact to local community economic development as available non-Port
property would be used by contractors for temporary construction laydown facilities. 
Contractor parking facilities would likely be displaced by future SAMP development in
the next ten to fifteen years.

Alternative 2)  Complete the Project without Acceleration Work 
Under this alternative the contractor parking improvements would be completed and that
function relocated to SEPL later this year.  In addition, the remaining improvements for
construction laydown, SEPL storm water management, and field offices would be completed
next year. The construction laydown improvements in Lots 1 and 2 would not be accelerated.
The total estimated cost for this alternative is $8.8 Million and includes the cost of the project
improvements and the increased bid costs for the early projects that cannot be accommodated in
a Port provided logistics facility. This is not the recommended alternative. 
Pros: 
Provides the necessary space for contractor parking (900 parking stalls) 
Provides the necessary space for construction laydown facilities (9.6 acres) and avoids
additional soft costs due to acceleration (estimated at $50,000) 
The field offices would be renovated in order to extend their useful life 
SEPL storm water management facilities would be updated to meet current permit
requirements 
Cons: 
A portion of the Aviation capital program needs construction laydown space for
temporary construction trailers in late 2015.  Since these facilities would not be
available until 2016, the 2015 contracts would have higher construction bid costs since
the contractors would need to provide these facilities elsewhere. Assuming the impact
is 1% of the anticipated contractor bid costs, the estimated cost for the affected projects
is approximately $1 Million. 
Contractor parking, construction laydown, and the field office locations would likely be
displaced by future SAMP development in the next ten to fifteen years 
Alternative 3)  Complete the Project and Accelerate Work 
Under this alternative the contractor parking improvements would be completed and that
function relocated to SEPL later this year. A portion of the construction laydown improvements
would also be accelerated and completed later this year. The remaining improvements for
construction laydown, SEPL storm water management, and field offices would be completed
next year.  The total estimated cost for this alternative is $7.8 Million.  This is the
recommended alternative. 
Pros: 
Provides the necessary space for contractor parking (900 parking stalls) 
Provides the necessary space for construction laydown facilities (9.6 acres) including
the work planned to start later this year 
The field offices would be renovated in order to extend their useful life 
SEPL storm water management facilities would be updated to meet current permit
requirements

Cons: 
Costs include additional soft costs due to acceleration (estimated at $50,000) 
Contractor parking, construction laydown, and the field office locations would be 
displaced by future SAMP development in the next ten to fifteen years 
Alternative 4  Provide Additional Construction Logistics Facilities Off-Site 
Under this alternative the existing construction logistics facilities would be used in their current
condition and additional facilities would be constructed either north (located on South 146th 
Street) or south (located on South 200th Street) of the Airport on Port-owned property late next
year. The remaining improvements for the field offices would also be completed next year. The
total estimated cost for this alternative is $10-$15 Million depending upon the site selected, plus
increased bid costs for the projects that cannot be accommodated in a Port provided logistics
facilities. This is not the recommended alternative. 
Pros: 
Provides the necessary space for contractor parking (900 parking stalls) 
Provides the necessary space for construction laydown facilities 
The field offices would be renovated in order to extend their useful life 
Cons: 
A portion of the Aviation capital program needs construction laydown space for
temporary construction trailers in late 2015.  Since these facilities would not be
available until 2016, the 2015 contracts would have higher construction bid costs since
the contractors would need to provide these facilities elsewhere. Assuming the impact
is 1% of the anticipated contractor bid costs, the estimated cost for the affected projects
is approximately $1 Million. 
The existing construction logistics facilities would not be reconfigured to efficiently
support the number of anticipated temporary construction trailers. Therefore, additional
facilities will need to be provided at an estimated cost of $10-$15 Million. 
Given the longer development schedule required for undeveloped property, the
additional construction logistics facilities that are provided off-site would not be
available in time. The impacted projects would need to find an alternative solution, at
additional cost to those projects. 
Contractor parking, construction laydown, and the field office locations would likely be
displaced by future SAMP development in the next ten to fifteen years.
