O’Brien360 is currently working on two projects for the Port of Seattle at Seatac Airport. The first, O’Brien360 is part of the design-build team working on the International Arrivals Facility (IAF). This new, expanded facility is designed to meet growing regional demand for international service, enhance the passenger experience, advance the Puget Sound region as a leading tourism and business gateway and serve the traveling public well into the future. The project is the first LEED v4 project for the Port of Seattle and O’Brien360 has helped the team navigate how those standards fit with Port standards, Port sustainability goals and specific goals set for the IAF. As part of finding the route to LEED certification, O’Brien360 has collaborated closely with the Port of Seattle Environmental Program Manager as that team pursued LEED credits via for the Seatac Master Site via the LEED Campus program.

Recently, O’Brien360 was brought in, via a separate agreement, to support and complete documentation for a second round of Master Site credits. Many of these involve finding unique approaches for earning innovation credits for leadership projects the Port has undertaken at the Airport, such as implementing an extensive food donation program and the development of pollinator habitat.
