North Madison Substation

GRL Engineers took on an investigative project on the North Madison Substation in Wisconsin, analyzing acceleration and stresses in non-uniform piles during vibratory driving. The test involved Pile Driving Monitoring with the PDI-VIB Program. Read More

1100 Broadway Avenue in Oakland

The Case Pacific Company in California contacted GRL Engineers to help collect high-strain dynamic measurements using APPLE Drop Weight Testing with the Pile Driving Analyzer (PDA) on two Cast-In-Drilled-Hole piles. The project utilized CAPWAP Signal Matching Software to assess the collected data that was taken during testing. Read More
