The pile driver drives the 91.4 cm centers piles until the penetration under the last hammer blow is 2.54 cm in a quicksand (Bearing = 5.38 ton/m2). The driver’s 1-ton hammer drops 2.6 m. Piles are sawn off and surmounted by a concrete slab 91.4 cm thick. What average bearing power in Ton/m2, does this foundation provide?
