When the regional codes transitioned to the IBC the chapter numbering changed so chapter 17 in the 1967 UBC did not address special inspections. The required special inspections were listed in Section 305. As I recall there were about 4 or 5 special inspections at that time.
Can you look them up? As I recall they were piers, epoxy, welding, and something else. But I also remember getting special inspections on CMU pours as far back as the early 60s, but I was always successful in getting the city inspectors to sign them off for me, even recently I've been successful getting nice inspectors to sign off on epoxy and piers.
