So why were we pouring foundation again?? To make up for the mistakes of the original contractor.
Here are photos of the foundation. To the right wing side, the contractor ran out of concrete mix, so they finished that part of the foundation the next day. The flagstone patio was built by the first contractor (when they messed up the first attempt at the oven). The second contractor had to dig out to pour the foundation a little further back (front to back) and they poured it higher to match up with the patio level.
In the background of the second photo is the grill island that the first contractor built (they did a good job with that).
The completed foundation with the oven dome on top to help check dimensions. The dome will actually be further forward when it's actually installed on top of the hearth.
