The Oregon State Treasury Department building located in Salem, Oregon is the first USRC Platinum-rated building in Oregon and the first USRC-rated seismically isolated building in the United States. The Treasury Resilience Building is a 30,000-square-foot, 2-story, steel-framed building and achieves both a USRC Platinum rating at the design-basis earthquake as well as at the Risk-Targeted Maximum Considered Earthquake (MCER) as a result of its seismic isolation system.
KPFF used SP3-Design (now SP3-RiskModel Advanced) to choose a base-isolation system that reduces floor accelerations. This resiliently designed building is expected to survive a large earthquake and reduce expected losses down to 1% of construction costs. This will allow the Treasury to resume operations shortly after such an event, with little disruption.
