1. We typically use load tests or pile driving formulas to test driven piles, because they are precast. List all the typical tests that are recommended on drilled shafts in order to ensure they are properly installed and ready to be integrated with the rest of the structure. 2. In case that a test drilled shaft fails, i.e. shows lower capacity than the one you have predicted in your design, what would you do?
