Design Complexity 
Difficult Wayfinding 
Challenges                Solutions 
Difficult Wayfinding           Improve Wayfinding 
Provide more intuitive                Create open sight lines 
wayfinding for passengers        Provide open and unobstructed
within NSAT                      travel paths 
Provide more intuitive                Improve sign placement and
wayfinding for passengers         sign terminology 
connecting between NSAT,       Create markers (art, signage,
Concourse C and the Main        design features) in STS
Terminal                           stations and on Concourse
level

Design Complexity 
Aging Infrastructure 
Challenges                Solutions 
Obsolete Facility and         Improve Building
Infrastructure                  Infrastructure 
Aging HVAC and  systems          Seismically reinforce NSAT for
infrastructure (40+ years)           life safety 
Confined passenger areas          Install energy efficient systems 
Inadequate back of house           Provide larger and better
support space                     located support areas 
Uncomfortable and crowded        Upgrade data and wi-fi
gate lobbies                        performance / coverage

Drivers for NSAT Expansion 
Airlines 
Travelers 
Level of Service (LOS) Rating (Using IATA Standards) 
LOS Without Expansion: D through F 
LOS With Expansion: B+; allows for growth 
Dining, beverage and retail areas 
Current Area:             Approximately 19,000 SF 
Projected Need:         Approximately 48,000 SF 
With Expansion:         Approximately 46,000 SF 


15

Recommendation 
Expand NSAT to 20 Contact Gates 
Least cost option for adding gate capacity at Sea-Tac 
Expand SSAT or Concourse A - demolition of hangars (AAG,DL) 
Expand Concourse D  relocation of expressway for only 3 gates 
No opportunity to expand Concourses B and C 
Consistent with long-range airport expansion plan 
Airlines approved this project 
Greatly enhances LOS for North Satellite passengers 
Restrooms, holdrooms, concessions and passenger amenities) 
Without expansion: 
Airport-wide gate capacity requirements not met 
Increases hardstand passenger loading & unloading 
Increases holding passengers on aircraft more frequently

NSAT Expansion Design 
20 Gate Layout 
Aircraft Positions 
Loading Bridge = 20* 
Ground Load = 7* 
* North end will
accommodate both 6
loading bridge positions
and 7 ground load
positions for flexibility

Sustainability In Design 
High Performance Building Systems (HVAC, Lighting) 
High Performance Glass and Building Envelope 
Water Conserving Fixtures 
Interior Daylighting 
Regionally Sourced Materials 
Materials with High Recycle Content 
White "Cool" Roof Materials for Heat Reflection 
Informative / Interactive Opportunities for Passengers 


23

Project Contracting Approach 
Recommendation: 
Use General Contractor/Construction Manager (GC/CM) with
Prequalified Mechanical & Electrical Subcontractors 
The Project Meets RCW 39.10.340 Criteria 
Complex scheduling, phasing and coordination 
Facility must continue to operate during construction 



24

Benefits of GC/CM 
Early involvement by general contractor, electrical &
mechanical subcontractors improves the design and value
engineering process 
Opportunity to perform early work or long lead procurement 
Potential to minimize operational impacts 
Input into construction phasing plans 
Confirmation of construction costs in parallel with design
completion 
Opportunity to use 3-dimensional modeling during design
phase to reduce systems conflicts, lower costs, and reduce
the potential of change orders
