Why is it necessary to step footings on a sloping site?

Footings, the concrete pads upon which foundation walls are built, must be located beneath the frost line in order to prevent a building from heaving when the ground freezes. If the site is sloped maintaining a constant elevation for the footings would either cause the footings to be above the frost line or significantly deeper than the frost line at one end of the building. Stepping the footings enables them to follow the slope of the site and remain below the frost line without going too deep under the ground. It allows the foundation wall heights to be minimized because the footings are kept as close to the surface as possible.

What is the difference between footings and foundation?

We could start with the argument that both words mean the same thing, that is, a basis on which anything is established. However, this is not the true answer to the question, shallow foundations are often called footings which are embedded about a meter into soil. A spread footing consists of strips or pads of concrete extending below the frost line and transferring weight to the soil or bedrock below. A foundation, or a deep foundation transfers the load of a structure through the weaker top soil to a more solid foundation underneath. There are different types of foundations, as driven piles or drilled shafts for example. Foundations have sufficient load capacity and are designed by a geotechnical engineer whilst footing need only the expertise of a structural engineer
