How to install outlet boxes in a SIP walls
During the plan stage, you mark up your drawings with every location you think you might want an outlet or switch on an outside wall. When the panels are being manufactured, they cut vertical chases into the foam at those locations; and then mark the OSB top and bottom. As the builder is setting the panels, we drills holes through the bottom plate and through the top spacer and 2x6.
I made a template for my router by tracing around a face-mount box with a marker. By cutting to the outside of the marker line, the hole is the right amount "oversize" so I can use a collar round the router bit. Here are pics of the sequence during install.
