I'm a bundle of jangled nerve about my foundation being done tomorrow. I keep envisioning some kind of massive failure or disaster that they won't be liable for. I know one of the worst things that can happen is the plumbing is damaged under the slab. I intend to watch them do the job if only because I find it interesting (I promise to stay out of the way), so are there any red flags I should watch for, like code words and furtive looks... or running and screaming? I'm already concerned about the sprinkler system. (They know how to get around that. Right?) :::sigh::: I guess THIS is what husbands are for.
