In response to Re: Installing a bathroom in a basement

My son has purchased a home that had the waste plumbing stubbed in the basement.

The 3-inch drain pipe protrudes about one foot above the floor and the other drain pipe is located
about 12 inches away and protrudes up about one foot.

I assume that the basement floor will need to be broken around the stool drain so the pipe can be cut

Yes, a little bit of concrete will need to be broken out around the three inch pipe to install a water closet flange. The pipe that is 12" away is most likely the vent pipe for the toilet.
Some plumbing inspectors will allow a lav to be "wet" vented over a toilet, using the vent as a lav drain. If this is the case in your area, the trap arm for the lav may be extended out, up to 42" from the vent to the wier of the p-trap of the lav. (where the trap takes a bend down)

The lav must be no closer than 15" from the edge to the center of the toilet.
