The whole icpi manual is here: http://www.icpi.org/studyicpi
Are you sure the L.A. is specifying the base requirements or the engineer? A L.A. doesn't know anything about soil mechanics so I would follow the ICPI specs over the LA specs. ICPI advises against precompacting the bedding layer for interlocking pavers but if you are installing large paving slabs then you may have to precompact the bedding layer. Even with precompacting, the bedding sand thickness is still the same at 1in.
