I have a finished basement which I would like to add a bathroom (shower stall, sink, toilet). The area that I would like to do this in has the house waste line exposed (above the concrete slab) and I have two clean out ports. Since the basement has high ceilings, couldn't I build a platform to raise the area where the bathroom will be and connect the pipes for the toilet, sink and shower to drain into the clean out port? I think it would be easy to vent because there is an existing nearby vent I could connect to as well. Would this work?

Does this pipe extend BELOW the concrete or go through the wall?
I get a good laugh every time I see one- too lazy to jackhammer the concrete, or think its cheaper to just "build a platform". There's nothing quite like walking "upstairs in a basement" to use a bathroom!
If you're going to do it- DO IT RIGHT OR DO NOTHING AT ALL.
As long as you can get said floor above this waste line for proper grade of newly installed waste, and maintain a reasonable ceiling height I see no problem. Pumping said waste up would be cost prohibitive. The problem is I see is tying into an existing vent stack being of sufficient volume of added connections.
I would consult a knowledgeable plumber in your specific application.
This post is a great example of why being an electrician is easy.
A water closet is required to have a vent. I'm not sure what point you're trying to make, but venting would be critical in this application if the OP intends on tying into an existing stack.
I'm quite familiar with what a vent stack is. It is you that claimed it's not needed.
I'm not sure what point you're trying to make here? HE HAS A PROBLEM WITH TYING INTO AN EXISTING VENT STACK! You cannot simply add a water closet, and lav to an existing stack unless it was oversized, which is unlikely.
I had 2 semesters of the UPC (Uniform Plumbing Code), and a lifetime of being around these guys. I have a lot of respect for a good plumber, and is why I suggested he seek professional help.
That's the easy part. If close enough, the toilet itself needs no vent.
I thought the same and it might have been within code in the early 90's (one guide I had then showed a picture of it). I've subsequently learned that any fixture downstream of a water closet needs to have an air vent. It makes sens too as the vacuum created by an large volume of water could suck out the water in traps downstream.
To the OP, when we bought the house, it had a toilet that mounted to the wall and I thought it would be easier if we had raised fixtures. In re-thinking it, it was easier and better to just jackhammer the concrete and replace the waste pipe, connecting where we needed to be.

And?
One of the biggest arguements going on right now in some states (mostly northern states because of unions) is which code to adopt(?)
If you own a building, design a building or have to regulate a building, you pretty much support the IPC. If you have to put plumbing into a building, you like the UPC, because it sells more plumbing. Some of the examples are pretty idiotic; my favorite- a "waterless urinal" requires a supply line, according to the UPC. No wonder unions love the UPC so much.
I for one support and advocate the IPC. Mainly because with one code, no matter where you go, to either work on, install, or service the "rules" are the same. The same could be said for the UPC but...
