the subsurface strata is sandy from medium to dense.

RE: cast in situ concrete piles

If the holes are excavated immediately prior to concrete placement then a minimum strength of 80% of F'c is recommended before disturbing the adjacent soil. Using high early mix designs, this can be less than 24 hours.
