Where's our concrete?

They've now added two layers of gravel (the second was somewhat finer than the first), and they also added some additional waterproofing material along the edges. We got an e-mail message from Steve today indicating that the plumbing had passed inspection and we were ready to get our slab poured. Hopefully, if the weather holds (which it is supposed to all this weekend and well into next week), I would think we would have a foundation in place very soon!
