I need information about applying advanced framing techniques(OVE) to multifamily homes from 3 to 4 stories. How appropriate is OVE for this type of building?

"OVE" framing wall panels are not totally compatible with multiple stories. "TFC" wall framing wall panels with 2,3,or 4 stories of continuous studs (Finger Jointed is allowed at varied lengths to get the 4 story by 12" wide panels. Individual panels are to be joined with mostly full sheats of sheathing while the factory made panels can have up to 90% of the sheathing factory attached to the studs to make up the panels. Openings can be made after erection with focus to change the partial boxed beam into complete boxed beams.
Another part of the focus is to use 24" center windows as much as possible to eliminate requirements for both headers and double studding.

Your reference to OVE framing is a step in the right direction, but OVE framing requires top and bottom plates (thermal conductors)for each story of the building. The almost universal use of full outer wall structural sheathing practice way over reinforces the slight need for lateral strength. To compensate for this, I would subtract all top and floor level horizontal plate studs from outer walls. This would not leave flimsy areas if the structural sheathing is inside under the gypsum board. This move also allows intersecting wall stud starts with only a screw mounted steel stud. Further interior wall framing should be with steel top and bottom plates with wood studs @16"o.c. attached to the sides of the top and bottom plates. This is a forgiving, but tight support that doesn't interfere with stressing of the designed roof loads.
With the above elements made into floor, wall, & roof panels that are joined mostly with truss plates driven home with a porta-power c-clamp, the whole house becomes a whole house truss with much improved resistance to wind stress and moisture encapsulations.
This type of greater strength, greater durability, and greater insulation also dovetails into greater remodel-ability & ~70% reduction in shell costs plus easier routing of plumbing, electrical, & HVAC runs.
This in turn re-opens the 1960's practice of doing shell homes to let buyers do the interior finish work. This also invites student at vocational school part time jobs doing OJT repairing unskilled mistakes. This provision also allays lender fears for lack of builder/buyer talents.
This lumber saving art is exportable and encourages cement block builders to avoid wind and quake damage intolerant materials, & develop local lumber industries in quake ravaged areas.
