You will need to check the UL listing of the pipe and the pipe manufacturer's tech data regarding the loading the pipe can take from building foundations and other loads such as traffic, truck wheel loads on flexible pavement(asphalt), most of the underground plastic pipe is not listed for use above ground, and you are required to use a DI transition piece. I have seen AHJ require the removal of the plastic pipe and replacement with DI transition piece, very expensive after floor is poured and walls are up.

As of right now, section 6.3.1.1.1 will read: 6.3.1.1.1* Underground pipe shall be permitted to extend into the building through the slab or wall not more than 24 inches. The annex note reads: A.6.3.1.1.1 Extending the underground into a building provides working room to transition to the appropriate above ground piping. Environmental conditions should be considered as outlined in 23.1.6.1.2 That was voted on in the report on comments, 13-79, Log 34. Interesting, to say the least.
