Structural Expert Witness in Downey: Local Conditions That Matter
Downey sits near the Whittier Fault trend within the LA seismic framework — high regional demand, and its post-war tract housing stock makes retrofit evaluation broadly worthwhile. Downey cases often turn on causation and standard of care: was the damage seismic, settlement, water, or defect — and did the design or construction meet the California Building Code? Dr. Mousavi brings a Ph.D. in structural engineering (Texas A&M), 20+ years of experience, 7,000+ projects, and peer-reviewed research to those questions.
Seismic Conditions
Downey sits near the Whittier Fault trend within the LA seismic framework — high regional demand, and its post-war tract housing stock makes retrofit evaluation broadly worthwhile.
