Miyamoto provided structural engineering services for this five-story science classroom building built at a time when the CSU was experiencing tremendous growth. Between 1984 and 2003, Placer Hall was one of almost a dozen new academic and service buildings to be built, nearly doubling the campus’s size. Since then, this geology building has become one of the signature structures on the Sacramento campus. The United States Geological Survey scientists and staff occupy the top floors; the college’s geology department is located on the first and second floors. Miyamoto implemented a structural system of steel moment frames with composite floor beams and fluid viscous dampers for seismic energy dissipation.
