A footing sits in a trench in the ground, and the wall, porch, addition or column goes on top of it. The kind you need depends on whether your project rests on walls or on columns, so that's the first thing I ask. The footing gets buried soon after the pour, which is why the digging matters more than anything you'll see.
The price moves with how many footings there are, how far we dig to reach firm ground, how much steel goes in and how easy it is to get a concrete truck to the spot. Your written estimate puts each part of the work on its own line, so you can see where the money goes.
The schedule mostly turns on three things. One is the permit, when the job needs one. Another is a soil engineer's visit, if the ground calls for it. The last is the weather on pour day. When your job needs a permit, we pull it with the city.
