Is it really OK to pound concrete anchor bolts in place?

I just had my 3&#; high foundation walls poured today.  Between using a super-plasticizer and delaying over an hour to start inserting the anchor bolts, the concrete was already setting quite a bit.

Half-way through, it started taking them nearly 15 seconds of intense manual effort to sink a bolt to its proper depth. Then they&#;d spend a full 60 seconds pulling the bolt up and down in the hole!  They insisted that this will properly consolidate the concrete around it.

Then they started using a hammer to insert bolts as the concrete continued to harden!  They followed this up with their standard policy of jerking the bolts up and down in the holes for a prolonged period before sealing the hole in the surface with more concrete.  

I even have videos of them doing this!  When I repeatedly stated that I didn&#;t believe this procedure would anchor the bolts securely, he insisted that he&#;s been doing this for years, everyone does it, and he guarantees it&#;s just fine.

I&#;m convinced that the bolts are not embedded properly.  I believe that all that motion of the bolt in hardening concrete just forces water and fines into the hole, and pushes larger aggregate aside.  Which could significantly weaken the anchor.

I don&#;t want to accept this quality of work, but I don&#;t know if I can insist that this be corrected. Prior to starting my home, I could not find any local contractor willing to fix the bolts on the forms prior to the pour.

Is there any way I can prove that this is not adequate quality work? Do I need to consult an engineer? Is there something specific in the code regarding this issue?  Or am I just making a big deal out of this?  Thanks.
