If percussive piling is necessary, soft-start procedures must be used to ensure incremental increase in pile power over a set time period until full operational power is achieved.\n(2) The soft-start duration must be a period of not less than 20 minutes.\n(3) Should piling cease for a period greater than 10 minutes then the soft start procedure must be repeated.",
