If you look at the bottom rebar grid, you will notice that it has small concrete blocks holding it up.

Here's an excellent picture of a structural reinforcement rebar grid. These large concrete pads are used for heavy loads from wood or metal posts that will be carrying a lot of weight from the roof or floor.

They're using a lot of foundation support ties, because the forms are wide and will be holding a lot more concrete than the smaller ones.

Corner view of the building foundation. If you look at the bottom left-hand side of the picture you can see where they over dug the corner a little bit.

That's a lot of wood and metal, plus all of the bracing and supports for keeping the forms straight while pouring the concrete.

The plywood keeps the dirt out. Be careful doing something like this, because this plywood needs to be removed, eventually.

Here's another view of the plywood that's holding the dirt back.

Wow, look at all of that wood and metal.

Another picture of the inside corner of the building foundation before the concrete is poured.

The bottom of the picture shows two rebars lapping.

Another picture of the outside corner of the homes foundation.

This looks like an elevator pit. Most people don't realize how much work goes into this type of foundation.

Here's a picture of two stakes being used instead of one long one, to support the concrete forms.

A different angle of the same picture where the two stakes are being used.

There vertical rebar sticking out of the footing are a clear sign that they're going to use a block wall here.

Look at how straight everything is.

The other side of the garage forms.

In the picture above, you will notice the electrical conduit pipes that will be used later to supply the home of electricity.

Here is an upper view of the electrical conduit pipes inside of the concrete forms.

It's always a good idea to tape the pipe openings to prevent debris from falling into the pipes.
