Building has to be supported over a raft foundation of dimension 15 m * 25 m. The soil is clay having unconfined compressive strength of 20 KN/m2. The safe pressure to be applied at the base of raft is 180 KN/m2. The building has provision of basement floor then recommended the depth of raft foundation. use factor of safety 3.0 and unit weight of clay 19 KN/m3. Adopt skempton's approach.
