Wherever possible, route plumbing, wiring, and heating or air conditioning ducts through interior partition walls or spaces. If necessary, they may be installed in the vertical stud spaces of the PWF walls. However, studs, plates, structural blocking, and framing anchors between foundation wall and floor framing should not be cut or removed. In some cases, it may be necessary to provide a furred wall or ceiling chase adjacent to PWF wall for routing plumbing and ducts.
Electrical wiring in PWF walls may be routed vertically within the stud spaces to outlet boxes or switches, and pass through drilled holes in the top plates of the foundation wall for routing through floor joist spaces to other locations.
Insulation: When installing insulation between studs in the below-grade portion of basement foundation walls, provide a space of at least 2" between the end of the insulation and the bottom plate.

Note: Panel foundations can be site built or made in a shop. When made so it cover up items that need inspection by the Building Inspector. Third Party Inspection may be required. (inspect for grade stamps, treatment stamps, stud spacing, insulation, nailing, dip of saw cuts, plywood requirments are some of the item that a third party inspection will note.

All Panel Wood Foundations must be designed and installed in accordance with:
All current Building Codes Standards

While wood foundations are easy to build, this is only true if one is building from an accurate well designed plan. When such a plan is incorrect, or if something is left out of the plan or absent, or if a design is made using a guide manual (these are not design manuals); major mistakes can be made during the construction process. These errors cause problems for the owner, builder, and the building department.
