Carnation Walling - Finishing Forming
Implement groove keyway and holes for pipes etc and add extra bracing.
Implement groove plank, wood cubes, and walkways
Implementing and bracing pipes through walls
Where there are holes to allow electrical, plumbing, utilities, and vents through the concrete wall, it is best to use 4" PVC pipe cut to a length of XX". This is the right length for the wall width plus two pieces of 2-by either side to brace it. Where it is the actual 4" PVC pipe that will be used (eg air ducting), make the pipe longer so it can be joined to other piping.
(The pictures show bits of 2x4 to sometimes attach to the vertical bracing, but it is better to just always use Kreg screws to the batons.)

Wherever you think there might be a weak area in the wall it is good to add some extra bracing. Typically this means some horizontal pieces of 2x4 that are screwed between the vertical bracing assemblies.
Sometimes a long horizontal plank is useful to keep two windows in line. It also forms a useful shelf for tools and lights.

Move 6mil polyethylene edges
The large polyethylene sheet that hugs the contours of the EPS flooring blocks currently extends to over the 8" of wall EPS. The vertical rebar in the walls will be through puncture holes in the sheet. Just ahead of the concrete pour you need to cut and move the edge to go down the inside of the wall plywood.
During Concrete Pour
The actual concrete pour is handled in the next step, but it is worth noting that immediately after the pour, while the concrete is still wet, it is necessary to check the walls are still accurately vertical and if necessary adjust them using turnbuckles on the angled bracing.
After Concrete Pour
Remove the wall ties
Undo the nuts and pull out the threaded rod.
Remove thick plywood
The construction grade thicker plywood is easy to remove because the thin plywood stops the concrete from touching its surface.
Squirt PL-Premium into holes in thin ply
As well as filling the holes so they can be sanded and painted, the PL-Premium also secures the plastic pipe to the thin plywood so the plywood is less likely to fall off the concrete wall.
Fill EPS holes from outside
Do this all the way through with foam gap filler .
