Why Retrofit Matters in California

Many California jurisdictions mandate seismic upgrades for older commercial and multi-tenant buildings. A retrofit protects occupants, preserves asset value and keeps you compliant with local ordinances. iBeam manages the full scope — from detailing and fabrication to installation and inspection sign-off.
