It is usually clever to consult the crane company commonly they are interested in offering assistance and pertinent information.
125-inch of steel to your thickness on the piles. This will likely increase costs to the challenge if it hasn't now been accounted for through driveability analyses or lateral capacity needs. A quick discussion on the New York City Developing Code necessity for all pile steel to get designed assuming a produce power of 36 ksi or fewer, whatever the genuine product toughness, normally brings about piles which will have reserve capacity to account for one/8-inch corrosion."
