A water tank of 5 metres broad by 20 metres long is to be built at a depth of 0.8 metres below ground. The tank's water is 75 metres deep. A loose, medium-dense, typically cemented sand was visible in the bonings, and the water table was 2 metres below the surface. Plotted in below  Fig.are standard penetration tests conducted in the boreholes. Verify that the service-ability limit states and the ultimate limit are not exceeded.
