Washington State Legislative Building

Olympia, WA


Sensitive modernization of this 1927 building has preserved its failing structure for future generations with updated spaces and systems to meet current needs as well as safety, accessibility and security standards. Earthquake damage had adversely impacted the structure's condition, most notably by shifting the massive columns that support the dome (the fourth largest in the world). Our approach exceeded expectations for achieving these complex goals while also saving the client approximately $25 million over the previously proposed plan.

Because this project was designed to LEED for Existing Buildings standards, we evaluated innovative and cost-efficient energy solutions. Cooling load evaluations took into account the shading of the building's monumental columns, reducing the load by half from previous calculations.
