Selection of the proper hammer in pile driving and estimation of the total driving time

Engineers and contractors have been designing and installing pile foundations for many years. The most common way of installing a pile is driving of it by a hammer especially in marine environments.A hammer which is too small may not be able to drive the pile to the required capacity; or may need an excessive number of blows. On the other hand, a hammer which is too large may damage the pile or fails to operate properly after a few blows.
