Sea-Tac North Satellite Renovation and Expansion

The North Satellite modernization project expanded and renovated the 44-year-old facility to better serve passengers and respond to continuing growth at Seattle-Tacoma International Airport. It included adding eight new gates with a 240-foot extension of the building to the west, adding an upper-level mezzanine, doubling the existing dining and retail square footage, and introducing a rooftop Alaska Airlines lounge with views of the Olympic Mountains.

Parametrix, as part of a blended consultant/Port team, provided resident engineering, cost estimating, and change management services for all phases of construction of this project delivered via GC/CM. Responsibilities included contract administration, management of all RFIs and submittals, oversight of the final Phase 1 of the FAA paving and civil utilities, and support for the Phase 1A turnover to the Port and Alaska Airlines team. We also provided LEED certification support, oversight of all Phase 2 scopes of work, and oversight of the Phase 1A apron pavement remediation to keep the project on schedule for turnover. The remediation work included management and support of the Port’s Airfield inspection team, field services, change orders, and cost control. Cost estimating and change management support was provided throughout both phases.
