Carlos, it's clear that your company uses superior construction methods. I, too, would like to see pics of the on-going work.
But it seems like a small pond for all that effort and expense. How big is it? From the pics, it looks like only 4'-5' round. I can understand them wanting it to be deeper. But, gee, while they're at it, wouldn't they want to make it wider, too?
What do you do with the fish, in the interum?
