Joel:

Thank you for your reponse. This is one solution we definitely plan to use. My strucutral engineer here in Southern California tells me that glass anchors (epoxy) such as those by Hilti can be used in California for residential applications. However, I know from experience that not all jurisdictions in all states permit their use without a PE stamp and in commercial applications at least, pullout tests. In other words, the extra cost and delay of epoxy anchors in some states may be problematic.

I have seen widgets in Simpon's catalog for positioning AB's in formwork. Have you used those?

What is the best way to get subs to put in the AB's properly the first time, or is it entirely impossible?

How best to ensure subs form and pour a level concrete face at the proper elevation to receive the bottom plate/sill?

Thanks,

Stan
