How do you pour a footing and pier?
Dig and pour all footings and piers at one time, if possible. Have rebar and anchor bolts or post bases on hand, as you must add them to the concrete while it is still wet. Lay out the footings. The spacing between footings for support posts is determined by post placements, which are a factor of beam spans.
Can I pour my footing and slab together?
However, you may alter this construction standard by pouring a floor and footer at the same time in certain situations. Known as slab-on-grade, or a monolithic pour, this foundation method is quicker and less expensive than a multisegment pour.

How far apart should piers be?
8 to 10 feet apart
While 8 to 10 feet apart is a sufficient distance for foundation piers to support most structures that would sit atop a post and pier foundation, if the building is particularly tall or made of heavier materials such as brick or metal, it’s not uncommon to place the foundation piers even closer together.
How many piers do I need for a 10×12 shed?

How deep should a footing be?
Depth of Footings
Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.
