A planned subterranean vault for heavy power transformer equipment is required in an area where a thick deposit of weak soils exists. The vault is 8 m by 12 m in plan area and is 4 m high. The soil unit weight is 15 kN/m3. The approximate weight of the vault structure plus included equipment is 5,500 kN. It is proposed to apply the floating foundation concept to the design–installation of the vault, to eliminate the expense of deep foundation support. Does the proposal appear reasonable?
