Seismic Retrofitting.
We engineer seismic retrofits to ensure structural safety, strength, and life safety. Our engineering balances lateral stiffness to prevent collapse while maintaining flexibility to protect upper floors during seismic events.
Ordinance 183893
City of Los Angeles Ordinance 183893 mandates structural evaluations and seismic retrofits for existing wood-frame soft-story buildings. We perform detailed site assessments, develop compliant engineering plans, and guide property owners through the mandatory retrofit timeline to bring multi-family residential structures into full compliance with city standards.
Ordinances 184081
Ordinance 184081 regulates mandatory seismic strengthening for non-ductile concrete buildings constructed prior to modern seismic codes. Our team delivers comprehensive structural analysis, retrofitting designs, and engineering submittals necessary to increase lateral strength and prevent concrete frame collapse during major seismic events.
Soft-Story Retrofit
Soft story structures, typically multi story buildings with ground floor parking or large open commercial spaces, require specialized structural reinforcement to withstand lateral earthquake forces. We handle the entire engineering lifecycle: measuring site conditions for as-built plans, conducting structural modeling, engineering steel moment frames or shear walls, and securing city permit approvals for construction.
