Or enhanced driving program general performance. A restrike exam is necessary to ascertain alterations while in the soil toughness. A structural engineer will decide if modifications during the driving process or pile depth are necessary.
Inadequate driving method efficiency could be as a result of insufficient hammering performance or way too-tender cushioning. The soil may have a lot more energy, the next damping ratio, or bigger soil quakes than to begin with examined for.
