• Method 1: Pre-install anchor bolts into the concrete at the position of each wall.  Attach end stud of wall to anchor bolts

• Method 2: Shoot long concrete nails trhough end stud and into the concrete of the ICF wall

• Method 3: Glue the end stud to the foam

Some of our builders attach flashing metal or flattened drywall c-channel horizontally between the furring strips on either side of the partition wall. They attach 1 strip every 2-3 feet, then screw the wall stud into that. This leaves them a lot of "wiggle room" in exactly where they end up putting the interior wall. They also don't have to plan out where the interior wall goes before the pour, since the metal can be attached to the furring strips afterward.

The fastest and easiest trick I've seen is to push J-bolts into position at the end of the pour. Of course you have to have the locations of the walls marked before the pour. But you don't have to glue the bolt into place because the wet concrete holds it. The contractor I saw do this pushed the bent end in and hooked it around. When he realized he'd misplaced a couple, he pulled them out (didn't seal the hole and no concrete leaked out) and pushed them back in at the right location. Of course J-bolts are a bit expensive, but this might work with other fasteners, too, like a sill strap.

I think mechanical attachment to the concrete is best. Just gluing the end stud to the foam could let it flex around.

I used 1/2" x 7" concrete anchors and a SDS rotary hammer drill after the interior wall was up to attach the wall to the ICF exterior wall .I figure at a cost of a dollar a piece for the anchors that this worked out the best for my project.
