The existing neoclassical John L. O’Brien Building, which houses 64 of the 98 Washington State House of Representatives members, became both an earthquake and a fire risk after the destructive Nisqually earthquake in 2001. This project involved a $47.5 million renovation consisting of seismic and life safety upgrades, replacement of aging and failing infrastructures, energy conservation, and efficiency improvements to the four-story structure constructed in 1940 on the Capitol campus.
