I remember them saying that I needed to inspect the piers as well, but they were able to bring the piering forward and it happened without me inspecting anything. I've wondered from time to time about this issue. Perhaps it has to do with contracts that have a piering allowance - so they can show you how/why it's gone over the allowance? My contract (and others by some of the comments here) now have fixed piering costs, so perhaps the inspection thing is less relevant? I haven't heard of other builders doing customer piering inspections.
