The press-in method combines the sustainability advantages of traditional dynamic piling techniques (in that preformed piles can be extracted and the site reused) with the low environmental disturbance associated with bored piles. Through field measurements of ground-borne vibrations at press-in piling sites, a method has been developed to predict these vibrations. The reduction in ground-borne vibrations achieved through the use of the press-in method instead of other dynamic methods can reduce the separation between piling operations and sensitive structures by a factor of 10-50. The separation between the piling operations and the public can be decreased by a factor of up to 5. Equipped with this guidance, designers can predict the level of disturbance associated with the press-in method and thus confidently specify the technique in locations for which displacement piling could not previously be considered.
