Soft-Story Retrofit Engineering in Los Angeles: Local Conditions That Matter
Los Angeles is in a high-seismic zone with complex fault lines. Seismic retrofits and earthquake-resistant design are critical for older buildings. Open-ground-floor buildings in Los Angeles are the highest-risk structures in any earthquake — the weak story concentrates damage. Our retrofit designs add strength where the building needs it most, sized to code without gold-plating.
