SUBJECT:  2018 Q3 NorthSTAR Program and North Satellite Project Briefing (CIP #C800556) 
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. This update reflects that construction is well
underway, is currently progressing on schedule, approximately 12 weeks from the opening of
Phase 1A and is forecasting to remain within authorized budget. Phase 1A is an opening of 5
new aircraft gates, the north holdroom, concessions, and the river concourse leading from the
existing building. 
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 from 12 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. 

Accomplishments 
(1) Phase 1 Taxiway A/B Reconfiguration completed 
(2) East taxiway vehicle service road striping completed

Risks and Critical Issues 
(1) Ability to maintain current construction schedule for Phase 1 opening could be impacted
by further scope changes, operational changes, customer service, unforeseen or
unanticipated situations 
(2) Central Core phasing challenges  Complexity of central core escalator and elevator
phasing and impacts to passenger and operational levels of service 
(3) Adequately covering within budget non-discretionary/discretionary post final design
scope changes, change orders, errors and omissions and differing site conditions during
construction

per week on overtime 
(5) Cobus Operations  Maximize level of service; minimize exposure to elements; maintain
safety 
(6) Contractor Design Development estimate exceeds contractual allowance by $3.5M 
(7) Dining and Retail project completing on time for Phase 1 opening
