Galvanized or not galvanized??
(OP)
On one of the wood projects I am working on, the contractor is proposing to use Advance Guard borate treated lumber for sill plates, which he claims doesn't require anchor bolts be galvanized. It is our typical office practice to require galvanized anchor bolts where they are in contact with pressure treated lumber. Your views please. Thanks.

You will have to check into whether the Advance Guard borate treatment meets this.

Depending on the type of cladding you have on the walls, the plate and anchor bolts can be damp more than you'd like, so corrosion is an issue, without regard to the treatment method for the wood.
Tell the contractor he doesn't have to remove what's there, just go back in between and put the right ones in.

I have investigated the failure of many exterior walls from water intrusion issues. Galvanized anchors are usually intact. Plain steel ones are often rusted away or nearly so.

I agree with others, I have only used galvanized bolts in this situation.
