I see. Still don't know why he needs plumbling. I would guess he needs a permit in this case. Not sure that's how it works here to be honest.
From the OP
"The main level of the garage is off limits and cannot be changed or altered in any way except to accommodate the necessary plumbing for the loft level. "
Would there be tax implications for making a space above the garage livable?
It's a school project, guys. They expect high schoolers to be basic and dumb. Think this through that way.
Of course this varies wildly by jurisdiction. So the proper course of action is to... hire a lawyer/architect to advise you of the necessary requirements for that specific locality.The OP said he needed plumbing of some sort. Furthermore, when building finished walls, code calls for outlets every 6 to 8 feet depending on the municipality, and usually some type of lighting (or a switched outlet) you can turn on when you enter the room.
ALSO, and this is important, if you build these walls without a permit, the city can make you rip them out if not built correctly, fine you for not getting a permit, or charge you out the ass for a backdated permit.
So yeah, get a permit up front and do it right.

It's not homework, I volunteered for this. - ___-
No. Sound transmission is through rigid materials, particularly the screws in drywall.I'd think that 2 layers of drywall separated by furring strips would be good, cheap soundproofing. And cork flooring.
If you pull building permits there will be
Why would you volunteer for something you don't know how to do and then expect other people to do it for you? That's just...I'm not even sure there is one word for what that is. Bizarre. That's for sure.

Usually you build a second wall airgapped with the the exterior wall and fill the space between with vermiculite or something. There are also little channel strips that work like your idea, but they are made to no transmit the vibrations between the sheets of drywall. Sheer mass doesnt have much deadening effect, it's the composition of the materials that make up that mass. Whatever absorbs vibrations is good.
I saw a radio booth that had kiln dried sand in the walls once.
