Electrical and Mechanical
It is not recommended to bury electrical and plumbing in concrete walls and roofs because of the difficulty of making conduit connections and extra cost of installing buried electrical conduit. Instead, shortly after concrete is placed, they can quickly and economically be installed directly into the rigid foam insulation boards affixed to the interior faces of concrete walls and roof planks as is demonstrated in Figure 9.
The technology for electrical installation has by today been well developed and is standard practice in the ICF industry. No conduit is needed. Neither is it necessary to bury conduit in concrete elements. Wiring and outlets are installed directly into the foam board insulation, and not into the concrete, the latter being an expensive time-consuming process.
