I have a question, particularly for any special inspectors on the list. For expansion bolts we have always specified minimum embedment length on our drawings and schedules. In Hilti's Product Technical Guide (And I assume on others) the required hole depth is greater than the embedment by one bolt diameter. This is due to the fact that the load is transferred at the wedge not at the bottom of the bolt. My questions to the inspectors are this: 1) When you are checking depth of holes are you checking against minimum embedment or are you checking for the minimum hole depth (which will always be deeper for expansion bolts). 2) Does it create problems in the field when the plans list only embedment and not minimum hole depth? Which would you like to see specified on the plans? (Both??) As a design engineer I am very rarely on the job during anchor installations. We depend on the special inspector for these verifications in critical applications. My feeling is that we will need to be more specific on our drawings and schedules so it is very clear that we are getting the embedment we need.
