First of all the ICC, in it's wisdom, has assigned epoxy bolting to the special inspector, not to both the special inspector and the field inspector. The AHJ does have the right and responsibility to approve the special inspector, the way I read Chapter 17 is that Tiger doesn't have the right to second guess the special inspector, but he does have the right to disqualify the special inspector. I'm now quoting from the 2013 CBC (I'm retired and don't now if changes have been made, but be aware that the code shows that many changes have been made to the IBC by the CBC, but of course Tiger is in California):
1704A.2 Special inspections. Where application is made for construction as described in this section, the owner shall employ one or more approved agencies to perform inspections during construction on the types of work listed under Section 1705A. These inspections are in addition to the inspections identified in Section 110.
Exception: Special inspections are not required for construction of a minor nature or as warranted by conditions in the jurisdiction, as approved by the building official.
One of the biggest complaints I get from owners is the additional cost of Special Inspections, as one guy asked: "Why all these multi-layers of inspection?" The way I read it is Tiger either accepts the special inspection reports, or goes the the CBO and reports the special inspection firm suggesting their approval be withdrawn. I would call this "minor" and Tiger could try to get the SI's approval pulled and do the inspection himself.
