The attached picture shows a section through a proposed foundation wall, with the wood-frame construction above, and the floor frame hung inside the ICF. The proposed house will be built in a jurisdiction that requires all wiring be run in EMT (electrical metal tubing, i.e. conduit). We seek solutions for getting the tube-clad wire runs into the wall cavities along the exterior walls of the main floor. This need is mostly for receptacles, but there are other openings required, such as for wall lighting, switching, and exterior lighting. What works best here, if you know from experience? I thought one way to do it would be to place foam blocks, say 4 x 4 x ICF core thickness, glued and fixed into the tops of the forms and braced there, to serve as a punch-through cavity for elbow sweeps of EMT. The electrical sub would need to show us where these would be needed, and at what size. What else might work?

My picture won't attach. What is the secret?

Is it less than 100k in size? If not, do one or all of the following. Save it with your photo program to a jpg with a quality level of 8, or 80 to 85 depending on program. Secondly, reduce the resolution down to something like 800 x 600. Third, crop all unnecessary parts off from around the perimeter of the pic. Crop first, reduce quality second, reduce resolution third.

You can get a 1.2 meg pic down to under 100k pretty easily this way, with a minimal impact on the usefulness of the final product.

Gene - If I understand the problem correctly, than what I would do is lay up the ICF with strong backs that are slightly less than the bottom of the floor. Set your wall ledgers in place c/w with their anchors (which ever system you are using) but have at least 3/4" material between the top of the strong backs and the ledger to knock out later else the strongbacks could become trapped. Install the whole floor system and then have the electrician install the sweep 90º where needed. When he is done, pour your walls by standing on the nice big floor surface you already have in place. The floor system if properly installed will guarantee that you house stays perfectly square and level!!
