Not sure what you are asking. If you are wanting to build a wall in a basement, measure the height required between the floor and the floor joist, build the wall on the floor, stand the wall up with the top in place where you want the wall to be and drive the bottom in place with a small sledge hammer. You can also make the wall just a little bit shorter than needed and drive shims between the top plate and the floor joists before you nail the wall in place. Nail the top and anchor the bottom with either concrete screws, shoot nails in or drill 1/8th holes through the bottom plate and into the concrete and use a 16 penny nail to lock it in place. It can't raise up, so you just have to keep the wall from moving side to side.
**For a wall that runs perpendicular to the joists: Lay the top and bottom plates edge side up and mark the stud locations on both as you normally would. Then screw the top plate into the joists where it needs to go. Lay the bottom plate on the floor and staple black poly onto the bottom, flip it right over and staple onto the sides of the plate (never put untreated wood on concrete). Lay the bottom plate down close to being underneath the top plate. Stand a stud's inside edge on the outside edge of the bottom plate and mark its length where it touches the top plate. Cut to this length and position about 1/8" over the line you marked on the plates. Screw 2x diagonally through the sides of the stud into the plates using 2 or 2 1/2" decking screws (this will pull the stud to your line). When all the studs are installed, tap the sole plate in/out/left/right to square up the wall. Drill through the bottom plate into the floor and anchor with Tapcon screws or use a Hilti gun (powder shot nail gun) to anchor the base of the wall to the floor. I have done the first method many times and always ran into difficulty raising the wall unless it was made short on purpose. The wall is longer across the diagonal from the edge of the bottom plate to the edge that gets to the joists first if you make the wall height the same as the vertical measurement.
You can use untreated as long as you have a treated sill plate. Untreated wood should not touch the concrete.
The wall has a bottom plate or 2x4 laying flat that is nailed to the bottom of the studs. Two top plates at the top of the wall. The wall is built, stood up and nailed down to the floor. If the house is set on a concrete slab, bolts are set in the concrete and the wall is bolted down.

The easiest way is to build a rough frame out of 2x4's. Put two vertical 2x4's at the ends, out from the wall to make the shelf the desired depth. These rest on the floor and need no further support once the shelves are attached. Then build rectangular frames for each shelf you want. fasten these to the wall and the vertical 2x4's at the desired height. use 1/2 or 5/8 ply for the shelf surfaces. When I build these I make the shelve 18x84 inches to get 3 shelves form a sheet of ply.

Some houses are built on slabs, and some are built on a concrete footing. Then, comes the framing. The walls are made by 2x4's layed out 16" apart with a top plate and bottom plate added. Then, they raise the wall into place. They do this all the way around the house for the first floor. Then, they add floor joists (2x10) and cover them with plywood for the second floor. They build the second floor, and then use 2x6's to build the roof. The plumbers and electricians come in and add the pipes and wires. Then, the house is sheetrocked and finished up. That's the basic house. There are concrete houses and other ways to build houses. I think they use 2x6's in the walls in colder areas so they can add more insulation.
Walls are commonly framed with 2x4 lumber, known as studs. The covering is fastened to the wall to enclose it.
You will need at least 13-9' 2x4's, on 16" centers, and 2-16' 2x4's for plates. (Deduct plate thickness from stud length)
9 if the studs are on 16" center and 7 if on 24"
Every 16" and you'd need 25
12' is max for a 2 x 4 wall. You will need 69 studs for a 90' wall with 16" centers.
