Another good idea. I have some testing companies that say they can use ultrasound to determine the length. If this is true and it works I will report back with the results. If the length testing falls through I will perform a couple of pull tests. I think I can get to some of the outside bolts. The inside bolts are just under the elevated base frame. As you say, who cares what type of bolt it is or how long it is as long as we can get the load out of it that we need per our calculations (along with a healthy factor of safety).

As an additional thought to add to my previous posting (inspired by James' suggestion), you might be able to do a pull test to see if they holds 1.1 to 1.25 (as you see fit, or as your applicable code requires) of your maximum required design load. After all who cares whether the bottle is half empty or half full as long as there is enough left to satisfy your thirst?

If it's a wedge anchor, maybe you could drill one out and see what you've got. (See attached link). You might also be able to do a pull test on one without removing it. http://www.drillcodevices.com/removal.html

I am reviewing the anchorage of a hospital emergency generator with 40 - 3/4 inch diameter cast-in-place anchor bolts but the drawings do not show the embedment depth. Does anyone know of a field test to determine the embedment depth? I am thinking there must be some type of sonic test that could measure the rebound and determine the bolt length. Any ideas?
