Kent K. Sasaki



Kent Sasaki has performed engineering investigations on hundreds of structures, including high-rise buildings, warehouses, apartment buildings, houses, bridges, tunnels, aqueducts, seawalls, wharfs, water tanks, power plants, historic structures, mine processing buildings, and monuments. He investigates damage from earthquakes, fire, earth movement, landslides, flooding, vibration, blast, and construction defects.

Mr. Sasaki provides expertise in the differentiation between old and new damage; application of building codes to the repair of structures; and evaluation of materials using nondestructive, destructive, load, and laboratory testing. He has substantial experience with insurance and litigation claims, investigates large collapses, designs repairs and seismic retrofits, and evaluates defect claims. Mr. Sasaki assesses structures affected by corrosion and alkali-silica reactions (ASRs), authors technical papers, conducts research, presents at mediations, and provides expert trial testimony. As a commissioner for the California Building Standards Commission, Mr. Sasaki reviews and approves building codes (Title 24) for California.
