This presentation will be on the ongoing Port of Portland Terminal Core Renovation (TCORE) which started in 2020 and is slated for completion in 2026. The TCORE project at the Port of Portland carries a lofty goal of building a new resilient terminal that is designed to not only survive a M9 event on the Cascadia Subduction Zone, but be back in operation after a major Cascadia Event. In addition to the new resilient terminal, portions of the work go to improving the seismic performance of the existing terminal by reducing existing foundation loading and seismic mass, replacing diaphragm components, and reinforcing connections. The new expanded terminal will contain the ticket lobby, security screening, baggage handling and baggage claim, mezzanine offices and conference rooms, and a pre-security concessions area. This presentation will dig into some of the technical aspects of designing a resilient facility including the significant concrete work to upgrade the original 1956 terminal, the new wood roof structure and the extensive foundations that support it.
