A Peer Exchange and Review of Deep Foundation Testing Methodologies at Caltrans

There are two objectives of this study; first to perform a peer review of the Caltrans Geotechnical Services Foundation Testing Branch (FTB). This review will evaluate current practices used to for deep foundations (piles) on Caltrans construction projects. Some of the current test methods, practices and procedures include gamma-gamma logging (GGL); crosshole sonic logging (CSL); pile load testing, Pile Driving Analyses ,Sonic Caliper Testing and Vibration Monitoring. Information to be reviewed includes current operational practices and procedures associated with managing the testing program, conducting the tests, and managing the analysis and reports generated for Caltrans projects. In addition to reviewing Caltrans current practice, the review will identify best practices and improvements that can be made to the current methodologies used to accept deep foundations. Included in this effort will be the identification of new technologies that should be considered by Caltrans for adoption. The second objective of this review effort is to be available to provide advice to the Department regarding their continuing effort of reviewing existing GGL data and to evaluate processes for adequacy.
