Doing it myself
How do I arrange the rebar in the footing? What size square should I make? How do you figure out what depth to put the rebar at? Do I need 1 layer or two layers?
Thanks Daniel.You have provided minimal information. You don't say what load you are supporting. You don't mention the type of soil your footing rests on. You don't mention what type of column you have. You don't mention if you are in a seismic zone. You don't mention if you designed this footing yourself, or if an engineer told you that you need steel in the footing.
The design of the steel reinforcing is driven by the loads the footing needs to carry, the type of framing and columns, the soil conditions, and any seismic issues.
