A spread footing may be defined as a reinforced concrete footing poured into an excavation which has been dug by hand or by machine but which has been trimmed by hand to the specified dimensions. The primary purpose of this footing is to transfer vertical and horizontal loads from the building into the ground. Footings supporting walls are usually continuous. Footings supporting columns are usually square or rectangular, and may be designed to support individual or multiple columns. Footing selection depends upon the architectural layout of the columns with respect to each other and with respect to property lines or other obstructions.
