one hundred twenty five-inch of metal into the thickness from the piles. This will insert costs to the venture if it has not presently been accounted for by driveability analyses or lateral capacity requirements. A brief discussion on the New York City Building Code requirement for all pile steel to become designed assuming a yield toughness of 36 ksi or significantly less, regardless of the correct content energy, generally ends in piles that could have reserve capacity to account for one/eight-inch corrosion."
