Re: TO DETERMINE LOAD CARRYING CAPACITY OF EXISTING TIMBER PILES : WE WOULD LIKE TO DETERMINE THE LOAD CARRYING CAPACITY OF EXISTING TIMBER PILES. : WHAT ARE THE TEST METHODS AVAILABLE TO DETERMINE THE SAME? : DO WE NEED TO TAKE THE CORE SAMPLE TO EVALUATE THAT? . Does "existing" mean that these piles are already buried in the ground? In this case test loading might give you the realistic bearing capacity.
