Cornerstone Earth Group, Inc. provided geotechnical engineering, consultation, and construction observation and testing services for 𝗖𝗼𝗿𝗲𝘀𝗶𝘁𝗲’𝘀 new data center project in Santa Clara, CA.
This video shows Cornerstone observing Berkel and GRL engineers conduct high-strain dynamic testing on their sacrificial test auger cast piles. The sacrificial piles were previously installed to a depth of 60 and 100 feet. The testing operations include placing a test frame with a 16-ton weight over each test pile. The 16-ton weight is then dropped from heights ranging from 1 to 5 feet onto the pile’s head. Multiple drops, with increasing heights per drop, are performed to verify the ultimate capacity of the pile, confirming the design specifications.
