You are building a new storage building with plan dimensions of 20-ft x 20-ft.The building will weigh a total of 100,000-lbs.A geotechnical report indicates your project site contains a layer of normally consolidated clay at a depth of 50-ft below the ground surface.The layer is 10-ft thick.The soil above the normally consolidated clay layer is a Sand with a unit weight = 100pcf. There is no groundwater below the site.

Calculate the overburden pressure at the mid-point of the normally consolidated layer
