Shows Sonic Pulse Echo test record from 36-inch diameter cast-in-drill-hole (CIDH) pile 56 feet deep. Reflection from impedance reduction was detected above the toe reflection indicating a possible defect in pile shaft diameter from partial borehole collapse. Data was recorded by AGI from hundreds of Pulse Echo tests on CIDH bridge piles constructed for Alameda Corridor rail line trench in Central Los Angeles.
