Aprecast concrete pile, 305 x 305mm in size is proposed to be installed at a site where two layers of sand exist. The upper layer is 3.7 m thick medium dense sand with y= 16 kN/m² and 6 35º The lower layer is a thick deposit of dense sand with y 19 kN/m² and 6 = 37° a) Differentiate between bored and driven piles in processes to the surrounding soil. terms of the effects of their installation
