The site of a proposed civic building in the town of Whyalla was tested by means of 5 power-auger test holes. These bores revealed aeolian fine sands and silts and red-brown sandy clay overlying bedrock, probably Corunna Conglomerate. The soil profiles are very uniform in character excepting in the depth to firm bedrock, which varies from 10 ft. 3 in. to 16 ft. If it is intended to construct a basement, for which the site is very suitable, some excavation of hard rock will be necessary in the south-west corner. Elsewhere the building will be founded on firm, finely sandy and silty clay, underlain by bedrock at shallow depth. For a building without a basement it will be necessary to seat the footings at a minimum depth of 4 ft. below the surface. At this depth the maximum safe bearing capacity is estimated to be of the order of 4 tons per square foot, but since the soil here is fine and somewhat limey some significant loss of strength could result if it were allowed to become saturated. Properly constructed drains of adequate capacity therefore will be necessary to dispose of roof run-off and other waste water.
