>Post Moved< Basement Rough In Plumbing

We're in the process of finishing the basement in our home that was built 1.5 yrs ago. The builder did a "rough in" for a bathroom. I'm trying to figure out what we're dealing with, and if we'll need to vent any of these.

In the first picture (below), I'm assuming (left to right), bath tub drain, toilet, then sink. To the right of the stubs you can see the line from upstairs that seems to dump into the sewer. The three stubs must be tied into this under the concrete. Could I assume this would already be vented, or will I need to install a vent back into the top side of the pipe to the right?

This picture shows a 'turbo vent' and the floor drain. I'm guessing that this is just the vent for the floor drain to keep gases from passing back through the drain.

I'm trying to determine if we'll need to vent any of the three before framing in the bathroom to avoid needing to do any re-work. Any help or guidance anyone can provide is greatly appreciated.

No you cant tie into the main from upstairs..

Look above the pipe for the sink.. Look for a capped 1 1/2 line or 2" line.. That would be the vent if the builder did it right...

Is that a 2" pipe hiding behind the 3" toilet pipe? If so, that's probably the vent for the toilet that needs to be continued up and to the roof. It would also imply that the vanity is not vented yet either.
