   Mark,
   Talk to your local building inspector to verify that any suggested solution is acceptable. Retrofit anchor bolts are an engineered solution and are usually accepted as code-compliant. For more information on retrofit anchor bolts, see:

   Mark,
   Oh, and by the way -- don't hire that contractor for any future jobs.

   Martin, I've been a carpenter in Maine for 35 years and now I'm building my retirement home in Georgia. You can imagine my surprise when I didn't see the bolts. The contractor's name is "%#&*@!?". Now if you'll excuse me I have to get into the Zen of drilling concrete. Thanks again, Mark
