SUBJECT:  2018 Q1 NorthSTAR Program and North Satellite Project (CIP C800556) Briefing 
EXECUTIVE SUMMARY 
The North Sea-Tac Airport Renovation (NorthSTAR) Program is a collaborative effort of the Port
and Alaska Airlines (AS) to improve traveler experience and customer service.  The North
Satellite (NSAT) Renovation and Expansion project is the largest segment of the NorthSTAR
Program. This component project addresses the expansion of the North Satellite from 12 to 20
contact gates, modernization of the existing North Satellite facility including North Satellite and
Concourse C Satellite Transit Stations, and expansion of the baggage system to accommodate
the satellite expansion.  On August 15, 2017 the Commission approved the remaining
unauthorized funds for the entire NSAT project. The update reflects that construction is well
underway, is currently progressing on schedule and if forecasting to remain within authorized
budget. Current risks, concerns and issues are: 1) finding skilled and qualified labor as the
project ramps up for completion; 2)  finalizing  the  Concourse  C  vertical  transportation
improvements construction work plan and schedule that minimizes closure of the C STS station;
3) finalizing the operational aspects of the Phase 2 ground boarding to be safe and minimize
passenger exposure to the elements; and 4) negotiate the design development change orders
to remain within the contractual allowance. 
This presentation details the progress made over the past quarter on these projects. 
1.  CIP C800556 NorthSTAR NSAT Renovation & North Satellite Transit System Lobbies 
This project includes the modernization of NSAT and the satellite transit system (STS) lobbies at
Concourse C and North Satellite including infrastructure and seismic reinforcement, the
expansion of the NSAT to 20 contact gates and expansion of the baggage handling system to
improve customer service, provide a balance of holdrooms, concessions and circulation space
to meet the overall program vision.

scope changes, change orders, errors and omissions and differing site conditions during
construction 
(4) Ability to provide adequate terminal/airside facilities (12 vs 14 gates) to minimize
passenger & operational levels of service impacts during Phase 2 
(5) Uncertainty regarding certification level, Leadership in Energy & Environmental Design
