his Los Angeles apartment complex received a full Soft-Story Seismic Retrofit to strengthen the ground-floor parking level and bring the structure into compliance with the City of Los Angeles Mandatory Retrofit Program.
Before construction, the building’s open carport level left it vulnerable to collapse during an earthquake — a common issue in older multi-family housing.
Each column and beam was strategically placed to provide maximum support while maintaining tenant access throughout construction. The system ties directly into the existing framing to distribute seismic forces evenly, preventing soft-story failure and improving the building’s overall rigidity.
The result is a fully reinforced, code-compliant structure built to withstand future seismic activity. This retrofit ensures long-term safety for residents, protects property value, and provides peace of mind for ownership.
At Alpha Structural, we specialize in seismic retrofits for apartment buildings and commercial properties across Los Angeles. Our in-house engineering and construction teams handle every phase, ensuring a smooth, efficient retrofit process.
