We all know that footing is an inseparable part of foundation construction. They are built by the help of concrete with rebar reinforcement. The objective of footing is to provide adequate support to the foundation and restrain settling. Footings are especially crucial in the areas where soil condition is not up to the mark.
Usage of Combined Footing Construction practice may ordain using just one footing for two or more columns owing to:
1) Closeness of column
(for instance around elevator shafts and escalators )
2) Owing to property line constraint, this may restrict the size of footings at boundary. The aberration of a column positioned on the verge of a footing may be made up by joining the footing to the interior column.
