Concrete, bricks, wood and a… bucket?

During our pilgrimage to the house today we were excited to see a huge lump of concrete where there was just dirt, more dirt and bags of dirt!  The foundation is poured and we even walked around on it.  Isn’t it so pretty, all gray with tubes and pipes and stuff.

We also found that they had delivered our bricks and what looks like all the wood for the framing.  We are anticipating that they will start framing in the next day or two and that will be done by next week.  That’s a total guess on my part but I know the framers have been waiting to start.  Hopefully they are also waiting to finish and will jump right on it.

 

What is this?  Why is there a bucket–actually two of them–embedded in our concrete?  I don’t remember ordering the installed planter option.
