A square footing of size 8 8 m is founded at a depth of 2 m below the ground surface in loose to medium dense sand. Standard penetration tests conducted at the site gave the following corrected N60 values. Depth below G.L.. (m) N cor Depth below G.L.

Determine the immediate settlement of the foundation using Schmertmann's method by making use of relationship qe 4Ncor kg/cm, where qe is static cone penetration value in kg/cm. Assume settlement is required at the end of a period of 3 years.
