We have preserved, restored and seismically strengthened hundreds of buildings throughout the western states. As the nation’s oldest and largest earthquake engineering firm, we have evaluated many thousands of buildings for seismic vulnerability. Our practice is renowned for sensitively preserving important architectural features and finding effective solutions to seismic weaknesses that do not impact the architectural and historic integrity of the building. Our projects have won numerous historic awards from historic preservation organizations such as the National Trust for Historic Preservation, California Preservation Foundation, and The Foundation for San Francisco’s Architectural Heritage.
