The Soga Research Group/Center for Smart Infrastructure, in partnership with Caltrans, progressed with the instrumentation and field implementation of four Cast-in-Steel-Shell (CISS) concrete piles to better understand the geotechnical capacity of soil plugs of large diameter piles. Instrumentation, installation, and testing of four piles took place between June-July 2024. Fiber optic, piezometer, and strain gauge data was collected during various stages of the process including driving, restrike, and static load tests.
