Install bored holes (400–600 mm diameter) at strategic boundaries to allow displaced soil to enter, reducing lateral pressure on neighbouring structures. Pre-boring:

A pile is considered "set" if its downward movement does not exceed during a minimum holding time of 30 seconds It is standard practice to achieve two consistent "sets" by releasing the force and re-jacking without pause. Maintenance Install bored holes (400–600 mm diameter) at strategic

Contractors must perform a pre-construction condition survey of all buildings within the zone of influence. Safe vibration and displacement limits must be established in accordance with Building and Construction Authority (BCA) regulations.
