I am reviewing an installation plan for a number of drilled shafts. These are dry-cased, end-bearing shafts anchored in bedrock. The procedure states that once the bedrock is reached, the shaft needs to be cleaned out before the rock socket is drilled. Is this done just to verify top of rock or are there other reasons for it?
