<p>A foundation pier (28) for a building structure is formed by making a downhardly converging hole in the ground, for example by hammering or vibrating a conical mandrel (10, 12, 14) into the ground, and filling the hole with concrete (24) to form a pier having a slenderness or aspect ratio of length to thickness of no greater than 10. Precast beams (30) are placed between adjacent piers (28) upon which the structure is built and a floor slab is cast in situ utilising the beams (30) as lateral shuttering.</p> |
