This new house is also rather large compared to typical houses. The foundation for the main house is over 2,400 sq. ft. in area and the garage is an additional 800 sq. ft. A crew of 4 men has been setting up these plywood form panels for two days. Tomorrow they will pour close to 50 cubic yards of concrete in the forms.
The contractor will leave the forms in place for at least 24 hours before removing them. After 24 hours the concrete will be strong enough to support itself. We’ll then let the concrete sit for a few days over the weekend before proceeding with the project.
The next step will be preparing the sub-base for the concrete slabs, installing under-slab utilities and damp-proofing the foundation. We’ll also install the under-slab radon vent system and the perimeter foundation drains. Stay tuned for future posts as we continue building this new house.

How do you determine the width of the foundation wall? Is there a standard width that can support X amount of weight where X represents >90% of all homes Y stories high?
If we ignore the extra cost and perhaps extra curing time a thicker wall would require, are there any advantages to a thicker wall?
The wall thickness will very depending on local codes and loads. Most residential foundations are 8" thick but that can vary from town to town and state to state.
A thicker wall is stronger but not really necessary.
