When would engineers use Cone Penetration Testing instead of Standard Penetration Test?

(I) Standard Penetration Test is carried out in boreholes at 1.5-2m intervals. However, Cone Penetration Testing allows a continuous record of ground resistance profile.

(II) Disturbance to ground is less by Cone Penetration Testing when compared with Standard Penetration Test.

(III) The use of Cone Penetration Testing is faster and cheaper when compared with the combination of boring, sampling and Standard Penetration Test.
